Two-ended buffers are pretty good when used correctly, but nowadays they have a small chance of triggering memory ordering issues, where it is possible that written data to the buffer is still stuck in a distant cache, while the updated head pointer is already known to other CPU cores. To be absolutely safe, the head pointer would need atomic read/write, forcing ordering with a memory barrier. But in general the timing for such a bug is pretty narrow, and advanced CPUs (esp. intel/amd) make sure that things get stored in order anyway. Worst thing would also just be false data read, not a crash. Cheers, Udo ___ vdr mailing list vdr@linuxtv.org https://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

Re: [vdr] [PATCH] Fix undefined behaviour

Allocating a variable-length array of length 0 is undefined behaviour. The compiler is allowed to assume NumCamSlots>0 and optimize something based on that assumption. I think this is because some compilers avoid zero-sized data structures, so that every data structure has an unique address. In this case, if NumCamSlots is 0, the address of SlotPriority would be the same as of NumUsableSlots. (or whatever follows it in case of variable-length local arrays.) The alternative would be to ensure a minimum length of 1 (as its done for empty structs), but that would add notable overhead for a corner case, so its left 'undefined'.

VDR doesn't know much about what might have stopped shutdown externally, so the only way is to frequently retry. And since VDR never knows if shutdown will succeed, until the final termiante call, there needs to be a warning beforehand. After all, since there was no interactive usage for a long time, its very unlikely that there's someone actually seeing the shutdown messages pop up every few minutes. There's a more complex plugin interface to shutdown, where even the shutdown message can be suppressed while busy, but there's no easy way to extend this to external scripts. One could however write a plugin that provides more complex interaction with external scripts, like ask for shutdown, and accepting something like wait for 5 more minutes in return, without displaying messages.

My initial thought on the code was that it seemed to unnecessary do too
many double to int conversions, plus not doing any of them with proper
rounding. But I also thought, this might turn out simpler when
transforming it a bit. So I just did some math transforms, and it came
out quite embarrassingly simple:
// Scale to units of 1/1000 osd, with rounding
int x = (Rect.X() * 1000 + osdWidth / 2) / osdWidth;
int y = (Rect.Y() * 1000 + osdHeight / 2) / osdHeight;
int w = (Rect.Width() * 1000 + osdWidth / 2) / osdWidth;
int h = (Rect.Height() * 1000 + osdHeight / 2) / osdHeight;
// make aspect corrections
if (w h) {
x += (w - h) / 2;
w = h;
}
else if (w h) {
y += (h - w) / 2;
h = w;
}
mHdffCmdIf-CmdAvSetVideoWindow(0, true, x, y, w, h);
This should be functionally identical to the original code, except for
less rounding errors. I haven't tested it though.

Hi, I've uploaded the newest version of S2API Wrapper 'light', the wrapper patch to VDR that ensures DVB API compatibility to all DVB 5.0 API kernel headers. The new version fixes the DVB-S2 EPG bug that was introduced with 1.7.40, whenever the runtime kernel had DVB API 5.7 or less. To do so, the wrapper queries the API version of the running kernel, and switches to legacy code depending on that. At the same time, some of the VDR compile-time code switches depending on DVB API version of the kernel/driver headers were converted to runtime kernel switches. All in all, with the patch VDR should compile on all DVB header versions from 5.0 upwards, and all DVB features should be available as long as the runtime kernel supports them.

Re: [vdr] [ANNOUNCE] VDR version 2.0.0 released
Sorry for interrupting the party, great job for sure, but I think EPG on DVB-S2 is in fact buggy on DVB APIs 5.3 to 5.7. For these API verisons, the API 5.8 code fork replaces DTV_STREAM_ID with DTV_DVBT2_PLP_ID, and sends this command to DVB-S2 cards, even though DVB-S2 cards can hardly handle DVB-T2 commands. At least DVBAPI 5.2 will fail miserably on that, not sure if DVBAPI 5.3 to 5.7 is more tolerant in ignoring this. Suggested fix is to at least limit the DTV_STREAM_ID call for DVB-S2 to DVB API 5.8. Alternatively, you can take over my runtime check, or just drop support for DVB API 5.7 and older. Cheers, Udo ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

That was actually the next trick I wanted to check, whether there's a safe way to grep for old vs. new system and handle them differently: Old system would just make all, and instead of make install copy from the old folders, while new system passes make all and make install to the plugin. Another improvement would be a way to explicitly tell the plugin that its being build in the source tree, and that ../../lib etc. should be a target, but that needs to be supported by all the plugins. - Some compatibility strategy. Being able to build the same plugin source under several VDR versions helps plugin developers a lot. Though this is not VDR's concern, it helps to keep that in mind. So all in all, lets just look forward, not backward, and find ways to improve the system. Cheers, Udo ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

If you put all your plugins into PLUGINS/src under the VDR source directory (with the old Make.global still in place), change into PLUGINS/src and do for i in *; do make -C $i all; done I would guess that they build regardless whether they use an old or new Makefile.

Plus, any updated plugin (at least any built-in plugin) does no longer create the *.so.$APIVERSION file, and there's no generic way to do this. All updated plugins require an additional make install, that will create the *.so.$APIVERSION in some folder defined in vdr.pc. However, some old-style plugins will do totally different things on make install, like xineliboutput for example.

Re: [vdr] [DISCUSSION REQUEST] reintroduce a common make configuration file in VDR-1.7.35
I've been doing things with Make.config too, and would like it to be available again. My plugins usually followed this pattern: -include $(VDRDIR)/Make.global -include $(VDRDIR)/Make.config -include Make.config so you always had the chance to have optional control without patching makefiles. The global Make.config had lines like this: ifeq ($(PLUGIN),someplugin) ... endif to do build configuration for some plugins, or to force-off some warnings or fix certain compile issues, or even add distribution-specific quirks. (building for different debian releases from same source) So I'm in for a central method to do configuration, and not having to patch every plugin makefile and distribute several local Make.config files.

Directly accessing Make.config is way easier than reconstructing it, though. Speaking of all, I wonder whether some plugin out there used PREFIX or MANDIR, these are now off-limits. Oh, and by the way, with introducing $(CWD) some previously relative paths got hard coded, so moving these builds around or accessing them from different mount points might now be broken. For example, my default lib dir changed from ./PLUGINS/lib to /usr/src/pc/vdr/vdr-1.7.34/PLUGINS/lib, which only makes sense within a single virtual machine that cannot even run VDR at all. I'll have to add some overrides for that. Also, this needs some thoughts on compatibility, as I prefer to provide ONE source code package, no matter what VDR version it is for. I won't support X different plugin versions for Y different VDR versions. Don't make me choose between dropping pre-1.7.34 or post-1.7.33, you might not like the outcome. Right now, the old Makefiles luckily just do compile after all. I suggest to put the lines PLGCFG ?= /etc/vdr/plugins.conf -include $(PLGCFG) into each plugin's Makefile and that's it. Please, prettyprettyprettyplease NOT /etc. Source code should compile from within its source folder, and not interfere with global configuration.

In order to still allow the normal building of VDR (with all plugins in its ./PLUGINS/src subdirectory, the plugin libraries in ./PLUGINS/lib and the i18n files in ./locale) the VDR Makefile checks the settings of LIBDIR and LOCDIR when building the plugins from within the VDR source directory. If these macros have their default values, then the 'install' targets of the plugins' Makefiles are called. Otherwise the 'all' targets are called and the plugins are merely built, and will have to be installed by a call to 'make install-plugins'. This now also allows a user to copy a plugin source to any directory, change into that directory and do 'make' and 'make install' to have the plugin installed to wherever the local installation of VDR expects them. This has a major downside: LIBDIR and LOCDIR have two different meanings: First, the install target for make install, second, the default search path for VDR as long as --lib and --localedir is not specified. There's no way to handle them different. So either I have a build that expects ./PLUGINS/lib to exist, or I *have* to use make install, that currently creates a total mess. (xineliboutput even tries to write outside of DESTDIR, and luckily fails to write directly to /lib/.) I'm now (after 6 hours) at the point that I'll probably have to write an own lib and locale collector script that collects what has been in ./locale and ./PLUGINS/lib before, avoiding all the Makefiles, picking the right folders and files (there's no common way to find the .so file in the src folder), renaming them, etc. And I'm starting to think whether staying at VDR-1.7.33 wouldn't be the better solution.

Thats because VDR does splitting and editing on the data stream level, not on the audio/video-track level. Merging all the file pieces together always gives the original stream, with just very minor modifications. Editing based on time stamps would be a lot more difficult, as near the splitting point, data needs to be moved to the previous/next file, depending on whether audio is ahead/behind video. To make things more complicated, there's no guarantee that together with the I-frame also a new audio frame starts at the exact time stamp. For precise editing, an audio frame may have to be split and re-compressed. And for playback, the same applies in reverse: For pre-buffering, the A/V-data of the file end and beginning needs to be merged with proper offset again. This is all a lot more complicated than just splitting the whole data stream as one. For further processing, its the best to merge continuous stream parts into one big file, if the program cannot handle split files on its own. If you want to avoid the copying, take a look at vdrnfofs, a virtual file system that virtually merges VDR recordings into single mpg files.

Re: [vdr] RFE: Make VDR more friendly when using combinations of DVB-S, DVB-T and DVB-C
Why not just patch VDR so it cycles through channels that use the same channel number. No bothering with sql databases dependency, no altering the real channel numbers, no real pain that I can think of. For example, say you have 3 different sources using the same channel number: channel 100, dvb-s channel 100, dvb-t channel 100, dvb-c You tune channel 100 from your remote, it tunes 100 dvb-s. Press 100 again and it tunes 100 dvb-t. And again, 100 dvb-c. And again, loop back to 100 dvb-s. Also, instead of having to enter the channel number to cycle through them, maybe just use different keys (skip +/-, ffw/rew, some other keys) to cycle. If there's only one of that channel number, the cycle keys don't do anything. I have a similar idea that I've carried in my head for some time. The idea is to extend the channel number by another character, like '.'. That way you can store the dvb-s channel as 100.1, the dvb-t as 100.2, and so on. Or if you have the same channel in HD and SD, give SD the 100.3. The channel number 100 would be an alias for one of the 100.x channels, ChUp/ChDown will go to 101 or 99 directly. Recordings for channel 100 will also pick the first available of them. By hitting a '.' key on the remote, you can still enter the sub level, where ChUp/ChDown cycles between 100.x channels, or for timers to record from a specific source. Hitting '.' again could return to the top level of numbers. Of course this would require a rewrite of the channel numbering code, probably by making the current channel numbers internal only, and having an additional UI channel number as string. For the channels.conf syntax, this could be an extension to the :@ syntax, where :@. or :@100. or @100.1 starts a group of channels. And maybe an empty :@ to end the group without explicitly setting :@101 as next number.

Re: [vdr] Understanding the dataflow
Am 20.04.2012 23:58, schrieb Roland Tapken: What is cPlayer? As cTransfer implements both cReceiver and cTransfer I thought about it as some kind of frontend abstraction (FF-output, xine, streamdev-server). But it seems that cPlayer directly acts on cDevice, and that doesn't make sense to me at the moment. Furthermore, I'm still not quote sure where all these components where attached to each other. A cDevice can be both, input device and output device. A cReceiver can generally receive stream data like video, audio, subtitles, teletext, EPG, and so on, from a device. A cPlayer provides video/audio data for replay and feeds it into the output device. A cControl acts as the controlling interface of a cPlayer. It can handle keyboard and OSD interaction for a cPlayer device. A cTransfer is a cReceiver and a cPlayer, and just pumps data between these two. One thing to understand is that a cDevice can be stream source and output device at the same time. Generally, if you switch to a channel, the output device will be asked to show a specific channel. Only if the device itself is unable to do this on its own, a different device will provide the video stream, and a cTransfer is created to transport all the data from the receiving to the output device. 'Full Featured' devices can handle all of this internally. TT-6400 cards, for example, even continue to display live TV while the computer is rebooting. The general way to switch to a channel is: - cDevice::PrimaryDevice()-SwitchChannel(channel, LiveView) Instruct the primary device to switch to a channel - cDevice::SetChannel(Channel, LiveView) Actually handles the switch - cDevice::GetDevice(Channel, Priority, LiveView, Query) Picks the device that will be receiving. Tries hard to prefer the primary device (output device) as source device too. If receiving device is an other than the output device, a transfer control / transfer device is created to link them. One more thing to be aware of: Old non-HD FF cards can only either receive or directly display a video stream. If you watch and record a stream, the recording will usually be on a different device, so two devices will tune to that channel. If there is no other device, and both need to use the same receiving device, then live viewing has to be done using transfer mode. (might break on high bandwidth channels.) I'm not completely sure where in the code this is handled, though. AFAIK the TT6400 cards technically can record and display at the same time, but I'm also not sure whether this is already implemented or still handled the 'old' way.

It's originally posted by Maniac in this thread -- On the original topic, I see room for one improvement: The defaults of the new --cachedir and --resdir parameter are the defaults set by Make.config's CACHEDIR and RESDIR. This is a minimal change in behavior to previous versions, where these were handled by --video and --config. So any old VDR that gets updated will behave different in case that --video or --config is set, and now needs to also have --cachedir and --resdir set. On the other hand, there needs to be a way for distributions to set their defaults so that VDR finds them automatically. My suggestion: Allow to keep the default CACHEDIR and RESDIR un-set (empty), and if --cachedir or --resdir is not present, default to whatever --video and --config is actually set to. That way, the package builder can decide whether to set CACHEDIR and RESDIR or not, and if they're set, he has to make sure that the startup scripts get modified to support --cachedir and --resdir if necessary. For an extra, an explicit --cachedir= and --resdir= could also override an explicit CACHEDIR and RESDIR and revert to duplicating --video and --config.

Since HDFF cards AFAIK can split their stream on card for live view and recording, this isn't valid any more.

I think, here is already the first shortcoming in design. May be cause you're thinking with today plugins in mind? You got me wrong on that. My vision would be that timer UI and recording backend are two modules, and in a more complex environment there may be several UI frontends connected to one (or more?) recording backends. Any client should be able to edit timers on the server independently, the backend shouldn't even have any UI. In fact, any UI should be located in the frontend. For all sxfe fans: A frontend implementation itself could split into two parts, one server-side frontend, and one lightweight streamOSD display. Or keep latency low and put a more complex frontend on the client, that acts independently of the server backend. A high-level frontend could connect to one or more receiver backends to get channels on demand, would be able to schedule timers on recording backend(s), and would be able to play back from storage sources. Why not allow a storage plugin to act as a media player instead of just VDR recording server? Or on-the-fly transcoding on recording? Additionally it should be possible to configure the preferred input device used by this client for life-view. Other devices may be configured as fallback, in case the preferred device is not available. Thought of that. Generally, the default link between video frontend and receiver backend should be handled like transfer mode, to make things more unique. For the case of FF cards, there could be an additional prefer-this-backend-for-this-frontend rule, and a shortcut in transfer control that routes the video stream within the card instead of user space. As I already wrote, from my point of view, plugins may continue do networking, but the connection between backend- and frontend-part of vdr should not be public nor affected by any plugin. Well, I have a different vision: More like recording server and streaming client, where all the UI logic resides in the client, and the server doesn't need to know about UI at all. One advantage: Allow a frontend to connect to more than one backend. For example, have two 'full' VDR systems with receivers, recording capabilities and storage, and some streaming clients. And then let each of them use any receiver, any recording capability, and any recording storage that is available. As said, the server itself could spawn several clients, so sxfe-like lightweight viewers can connect to it. There could also be shortcuts if backends are on the same machine or in the same executable, so not everything must go over network. However, thats all pretty much vision and far from being reality.

Keeping this code separate (means: A plugin) isn't a that bad idea, I think. Of course, this plugin could be delivered directly with VDR, like the other built-in plugins. I don't think a plugin is enough. For better client-server VDR needs to support multiple clients watching different channels with different OSDs simultaneously. Not necessarily. I think the key solution is to modularize VDR's internal structures, with well defined interfaces between them. A receiving module that provides stream sources, a recording module that does all the timer work, a frontend module that can display, a storage module that can store and provide videos, for example. A timer menu that belongs to a recording backend, a recording menu that displays content of storage modules, several frontends that can connect to one recording backend or several storage modules, and all can connect to different sources. With defined and pluggable structures between them, its easy to have them either locally connected or linked over network. Whether that's done by a plugin or VDR internally doesn't matter. In any case this would be the biggest rewrite of major parts of VDR ever, with lots of breakage, total loss of plugin compatibility and very long development cycle.

This still leaves the live related receivers unhandled, and since there's no way to port the 'volatile' patch without reverting your changes, we still have the old osdteletext-channel-blocking bug. What about having yet another plugin callback that fires before switching a live channel? Currently, plugins get notified after channel change, and thats too late to disconnect receivers early. And since receiving at -1 doesn't have any special meaning any more, there's no way to get receivers out of way early enough. Roughly, the callback should be at the places where these two get called: DELETENULL(liveSubtitle); DELETENULL(dvbSubtitleConverter); (Thats how VDR's own receivers get out of way.) That way, GetDevice(ch, 0, true) will still have the weired behavior of returning different devices before and after initiating the live view channel switch, but at least after disconnecting all live related receivers, the correct device will be returned.

Am 27.02.2012 14:33, schrieb Frank Schmirler: Instead of a configurable LiveTV priority, your approach uses the fixed priority value 0 for LiveTV. The new idle priority of -100 opens the range for cReceivers with negative priority. The problem is, that *any* negative priority is still considered as may be detached anytime, so there's still no real cReceiver with less priority than live TV. Unfortunately not, because may be detached anytime is intentionally broken since VDR 1.3.7 (2004). Fixing it would reintroduce the Live TV freeze on recording start bug. Extending this to priorities down to -99 doesn't change anything, and I currently see no real advantage in it: Why would someone want an unimportant stream with priority -10, and another with -20? VDR itself doesn't use them, so anything below 0 would be the same. Maybe, with some ugly hacks, Streamdev could emulate the old PrimaryLimit by adding some kind of priority offset to all streams, but as long as the rest is all broken, there's no real point in it. - instead of any negative priority, only priority -MAXPRIORITY gets the special meaning of may be detached anytime See above. Would require transfer mode to run on -99 too, otherwise would re-introduce live TV freeze. - the constructor of cReceiver should use default priority -MAXPRIORITY, so not all plugins have to be updated to keep their previous behaviour - use LIVEPRIORITY-1 as priority for cTransfer Such -1 offset workarounds usually don't work, I would prefer not to have them. For example, one transfer device can still block another before detaching or via Streamdev. The only consistent solution is to give transfer mode the same priority as primary device live priority, either PrimaryLimit or 0.

Hmmm, didn't even notice that change... Anyway, I think a better way to fix the problem would be to change the priority parameter of the GetDevice calls involved from GetDevice(channel, 0, true) to GetDevice(channel, Setup.PrimaryLimit, true). There are two calls in device.c and one call in menu.c. My 'volatile' patch did this, and it worked so far. I like that a lot more than the 1.7.24 solution that just adds another quirk to the priority system. If in doubt, this should just raise the priority on channel switching. I don't think that it would cause any negative side effects, esp. since this priority is ignored at the end anyway. (see below) IIRC that whole Primary Limit thing was introduced because in the beginning the full featured DVB cards were unable to record and play at the same time. So it could happen that a timer occupied the primary device and left the user with a black screen. Since the old FF cards have been given the ability to do simultaneous recording and replay a long time ago, and the new TT S2-6400 has been able to do this from the very start, I'd rather prefer to do away with the Primary Limit altogether - to make things simpler instead of more complex ;-) Keep in mind that a recording on an un-modded SD-FF device nowadays can cause broken recordings because of limited bandwidth. Being able to record and play at the same time is a rather theoretical ability, especially if its transfer mode playback. However, I never had PrimaryLimit set to anything but 0. http://projects.vdr-developer.org/attachments/355/vdr-1.7.12-detachreceiver-4.diff For description: http://projects.vdr-developer.org/issues/show/10 Well, I don't like the idea of introducing yet another parameter (volatile) here. The priority should be sufficient to solve this. So if you can suggest a solution that works solely with priorities, I might take a look ;-) That patch actually goes the same way as the above fix, but beside that its more about the detaching issue, and just fixed the PrimaryLimit issue on the way, so its not directly related. Even dropping PrimaryLimit wouldn't solve this issue. One of the core problems is that VDR selects a new device for live viewing before disconnecting the old live device. Thus, all live related receivers will still be present and will block the current device from being re-used. VDR works around this just because live view has no receivers (FF cards) or -1 priority receivers (transfer mode, subtitles), that are always of lower priority than anything. As a conequence, VDR has to ignore the '-1 can always be disconnected' rule, or it would also disconnect transfer mode on timers, regardless of free devices. And this leads to the osdteletext issue that the teletext receiver still blocks the device on channel switch. VDR's own receivers also work around this because they get disconnected before doing the final and counting GetDevice call, but plugins cannot do that at that time. A clean solution should imho do these things: - Fix the find-device-before-disconnecting loop - Transfer mode devices with 'real' priorities - Honor the -1 priority as always-detachable In the end, you need to know at a very early point (ChUp pressed etc.) whether a device will be available for live view, even if it is still used right now, and might be used on (if ChUp fails). Letting VDR know that a device will probably soon be detached was one of the smarter solutions to this. Another alternative I was thinking of was to let the device know that a receiver is 'live-related', and thus can be canceled for another live view, but the 'volatile' solution was more general. Maybe it would be possible to manually lower the transfer mode receivers to -1 when calling GetDevice with live view, and raise them back to PrimaryLimit (or 0) at the end. Not sure if that's more elegant... Cheers, Udo ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

[vdr] [ANNOUNCE] S2API wrapper for VDR-1.7.23 (also upgrades 5.x to 5.3 API)
Hi list, And here I was, thinking that I could finally drop support for this old compatibility patch that noone really needs any more, and then the new VDR-1.7.23 requires linux-3.0 or newer headers to compile... yay... So here it is again: S2API Wrapper 0.8 is released, and should allow to compile a fully functional VDR on any DVB API headers from version 3.0 to 5.3, plus being able to use all features if the compiled binary is run on a newer kernel.

However, beside the actual problem, there also seems to be a serious problem with compiler flags, or otherwise this should have worked. More precisely, VDR itself was compiled with USE_LIVEBUFFER, while at least some plugins were compiled without USE_LIVEBUFFER. This should be fixed too, as there may be more serious issues when headers get interpreted differently by VDR and plugins.

This is one of the cases where it seems appropriate to have a lawyer for
every C++ coder, just in case he needs to wrangle the standard...
For info, the above references 14.6.2/3 of the ISO C++ standard, which is:
In the definition of a class template or a member of a class template, if a
base class of the class template
depends on a template-parameter, the base class scope is not examined during
unqualified name lookup
either at the point of definition of the class template or member or during
an instantiation of the class tem-
plate or member. [Example:
typedef double A;
templateclass T class B {
typedef int A;
};
templateclass T struct X : BT {
A a;// a has type double
};
The type name A in the definition of XT binds to the typedef name defined
in the global namespace
scope, not to the typedef name defined in the base class BT. ]
In our case, I'm not sure if another solution would be to pull in the
Add() method manually, by adding an
using cListT::Add;
to the class definition.
There's a similar use of this-First() in Save() that already requires
the this- in current compilers, and it can also be resolved by an
using cListT::First;
.

Re: [vdr] Undetected channels on transponders switching from DVB-S to DVB-S2
Am 11.09.2011 11:37, schrieb Henning Pingel: And this tackles another small problem: I think that VDR doesn't delete any channels from the channels.conf in any case. So outdated channels have to be removed manually. Has there been an attempt to offer a functionality that VDR makes a note of those channels that get the line frontend timed out while tuning to channel X in the syslog and offers those channels for manual deletion via the OSD in a special OSD page called Outdated channels? There's currently no 'official' method to track down channels that are no longer announced. There's a trick however: Modify your channels.conf so that all channel names start with [outdated], then start VDR and wait for a full transponder scan to finish. All existing channels will be renamed back to their proper names, and all remaining [outdated] channels can be dropped after some grace period. I use a more advanced variant using a small patch and a plugin, both currently not publicly released: The patch tracks a 'last seen' timestamp to all channels, where 0 means 'not seen since VDR start'. A matching plugin holds a second channel list and periodically syncs with the regular channel list, with the additional info 'first seen' and 'last seen' tracked persistently across VDR sessions. Also, the plugin renames channels that are gone for some time so they can be identified and deleted. This has however two downsides: First, a VDR that hasn't been running for some time will instantly mark all channels gone, and the same thing happens if a source is temporarily unavailable - for me, DVB-T is regularly not plugged, so all DVB-T channels are usually marked as gone.

change when called from the file parser, and then stay at the last code

Correct me if I'm wrong, but doesn't transfer mode receive PCR clock data, while playback is without PCR clock?

It is, in both ways: Any supported DVB card can always be accessed by s2api and by DVB v3 API. Functionality may be limited on DVB v3 API of course. S2api is part of any kernel = 2.6.28.

Or, of course, would have if I were using a developer version, which nobody would do. ;) Can you provide a diff that reverts just that changeset so we can use all the other goodies of 1.7.19 for now?

Yes. Either this or -fpermissive. But personally I prefer the initializer
here, but I must admit I don't understand the technical reason, why the
standard requires a user defined default constructor at all.
I also have to admit that I don't understand what difference this makes.
Apparently the program works, so the initialization must be taking place,
even without explicitly calling cCursesFont().
What makes this even more strange to me is the fact, that
static const cCursesFont Font;
requires an user-declared default constructor, while
static const cCursesFont Font = cCursesFont();
creates an temporary non-const cCursesFont object, and then uses the
implicitly declared copy constructor to create the final Font object. So
why is the implicitly declared default constructor forbidden, and the
implicitly declared copy constructor ok?
You'll really need an lawyer when it comes to standards specifications...

Re: [vdr] Stop live TV whilst in menu
Am 13.05.2011 01:49, schrieb Dominic Evans: For example, currently if I want to watch two or three recordings one after another, I go to recordings menu, play 1 till end, hit back (returning me to recordings menu), play 2 till end and so on. Each time I go back to the recordings menu to choose the next recording, I'm forced to see and hear whatever happens to be showing at that time on the last channel tuned, even when it has no interest to me... I know similar situations where I don't want to have live TV, for example if this would tune to problematic channels (streamdev client) or would interrupt other receivers. Another good solution to this would be a real 'dummy' device, a receiving device that permanently receives a still picture, and that would be assigned to a free channel number. This would also be nice for a playback-only VDR without receiving devices, to avoid the frequent 'channel not available' messages. I've once tried to write such a plugin, however these attempts were missing some code to turn a single mpeg still frame into an endless sequence with proper time codes.

8.5/9 of the C++ standard says
If no initializer is specified for an object, and the object is of
(possibly cv-qualified) nonPOD class type (or array thereof), the object
shall be default-initialized; if the object is of const-qualified type,
the underlying class type shall have a user-declared default constructor.
Interestingly irritating... Since I don't have an GCC4.6 at hand, I
*think* the source of the problem might be that cCursesFont has just an
default constructor. So it should also work if you add an empty
constructor cCursesFont::cCursesFont() { } ???
I thought such an empty constructor would always behave the same as the
default constructor...
Does anyone know the background why the standard doesn't just use the
default constructor for const objects?

I seriously doubt virus scanners have anything to do with anything. That seems more trying to take a cheap jab at Windows then anything else. My work PC is an Core 1 Duo 1.8GHz running XP. The PC boots to desktop in roughly a minute, but is not usable for another 2 minutes due to high CPU and disk load by McAfee virus scanner. (I use SysInternals Process Explorer to monitor.) Also, every day at 10 I cannot do anything CPU or disk hungry for 1-2 minutes because McAfee does its signature update. You really notice that, even without the sudden increase in fan noise. Just recently I've upgraded the machine from 1.5Gb to 3Gb RAM with noticeable speed improvements. (Visual Studio 2010 is a huge memory hog!)

Am 21.04.2011 21:01, schrieb VDR User: I can't believe a dvb card vendor sets their minimum requirements based on things such as McAfee loads. It would be absurd to do so. Probably not that specific, but they have to calculate an average OS with average software running on it, and for a Windows 7 + basic software, the hardware needs are not much different. Btw, I used XP as well for many years. However, my boot times were never more then 30 secs. However, I've never bothered running virus scanners or anything like that unless I ran into an actual problem (10 times since win95), in which case I ran one and then exited the app - never left one running full-time. Corporate network, and lots of USB sticks and USB HDDs moving around. Virus scanner is an absolute must have... My XP boxes all had 1GB or 2GB or ram. XP + 2GB + VS6 worked great. I may have also used VS2005 at one point but not since then. Is VS2010 really that much of a resource hog?? I've seen it hogging 1GB of RAM while compiling an medium sized project, 3-4Mb zipped sources. VS08 also takes its part, but VS10 takes more, especially if intellisense and compiler run in parallel. The new IDE is worth it however. Cheers, Udo ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

Thats probably because you need at least an 2GHz P4 to boot windows and a virus scanner nowadays. The CPU and RAM demands should be not much higher than with an old SD FF card, as long as you only handle the encoded video stream like VDR does. The highest 'demand' is probably having an PCI Express socket already. (Not that PCI bandwidth wouldn't be enough either, but PCIE probably seemed more future proof and simpler.)
