But why? I have no idea. It works for you with vomp. It worked for
me with streamdev when I tested this last year. But I had only
streamdev-server running and used vlc to switch channels.
Streamdev-client won't forward calls to SetChannelDevice and ProvidesChannel
to the server, if the current channel and the requested new channel are on the
same transponder. Instead it will just go ahead and later add the PIDs of the
new channel to the current connection.
Pvrinput obviously uses the same frequencies (i.e. transponder) and even the
same PIDs for different channels, so streamdev-clients current behaviour is
bound to fail. According to an other posting in this thread, it is not
possible to use different frequencies, so it seems the problem needs to be
fixed in streamdev-client. Please try the following patch:

Re: [vdr] Streamdev to Streamdev with PVRInput card
streamdev doesn't query for a new device if the current and the next channel has the same transponder. This is checked via the following define: channels.h:#define ISTRANSPONDER(f1, f2) (abs((f1) - (f2)) 4) //XXX All the channels in channel.conf have the same frequency, so streamdev only changes the receivers but doesn't query for a device. I havent understand exactly what you are doing. Do you use an analogue input (like scart) of the pvr500 card and the channel switch script changes the channel of another device ? If so, i could imagine the frequency in channels.conf doesn't matter and you could simply modify the frequencies. The frequency matters since he is using the tuner input. Lars. I think Rob's version of pvrinput has already the code for calling the externchannelswitch-script in case eTelevision and not only in case eExternalInput. (Otherwise it wouldn't work at startup). The code in ProvidesChannel() and SetChannelDevice checks not only for the same frequency, but also for the channel number: if ((Channel-Number() == CurrentChannel.Number()) (CurrentFrequency == Channel-Frequency()) (CurrentInput == input) (CurrentNorm == norm)) When Rob switches to another channel number, pvrinput should return needsDetachReceivers = true in ProvidesChannel(). It should also get a call for SetChannelDevice(). The problem is that both functions are never called - but obviously only in combination with running streamdev. ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

Re: [vdr] Streamdev to Streamdev with PVRInput card
Hi Rob,
for your (and only for your) problem there could be an easier solution:
When doing a channel switch streamdev queries for a new device while
the current device is still active (means receivers are attached to
the device). If no device could be found, streamdev detaches itself
and queries again.
If streamdev only queries for a device after detaching itself, the
pvrinput device gets closed and reopened again incl. executing the
channel switch thing. This is a really hack with some disadvantages
(e.g. like larger channel switch times in case of multiple channels in
a transponder) but i guess this would help.
I guess doing the following line should be sufficient in
server/connection.c (streamdev-version 0.5.0-CVS):
bool cServerConnection::ProvidesChannel(const cChannel *Channel, int Priority)
{
const cChannel *current =
Channels.GetByNumber(cDevice::CurrentChannel());
const cChannel *current =
Channels.GetByNumber(cDevice::CurrentChannel());
cDevice *device = CheckDlevice(Channel, Priority, false);
cDevice *device = 0;
if (!device || (device == cDevice::ActualDevice()
!cSuspendCtl::IsActive()
StreamdevServerSetup.SuspendMode != smAlways
current != NULL
!TRANSPONDER(Channel, current))) {
// mustn't switch actual device
// maybe a device would be free if THIS connection did turn off
its streams?
Detach();
device = CheckDevice(Channel, Priority, false);
Attach();

Re: [vdr] Streamdev to Streamdev with PVRInput card
Ok, will try this out tonight when I get home.
For info. PVRInput should treat every channel as a seperate transponder
(imho).
I think you hit the nail on the head though, it's not detaching the first
stream before starting the second, which is why changing channel on the
remote frontend from say 5 to 8 leaves the backend locked on channel 5.
Conversely, the vomp plugin always seems to detach, which probably leads
to longer channel change times, but works with pvrinput.
Could the patch below work for everyone if a conditional check for tuner
type P was put in?

Re: [vdr] Streamdev to Streamdev with PVRInput card
I have a PVR500 with the PVRInput plugin running on my Backend. I am using an old Hauppauge FF DVB-s card just as a frontend on another low powered system in order to throw the PVRInput channels to the kitchen. On the backend it's all working, however, switching between channels doesn't quite work, as the streamdev server will give the client the same channel over and over again regardless of what it requested, unless the device changes (ie, if I go from /dev/video1 to /dev/video2 it'll change channel). how do you force switching the video device? An example of the channel list is: 2-WTTW PBS_Affiliate ntsc;WTTW:67250:TV|NTSC:V:0:301+101=2:300=@4:0:0:30020:32:32:0 3-WREX NBC_Affiliate ntsc;WREX:67250:TV|NTSC:V:0:301+101=2:300=@4:305:0:30030:48:48:0 4-WTVO ABC_Affiliate ntsc;WTVO:67250:TV|NTSC:V:0:301+101=2:300=@4:0:0:30040:64:64:0 5-WIFR CBS_Affiliate ntsc;WIFR:67250:TV|NTSC:V:0:301+101=2:300=@4:0:0:30050:80:80:0 6-WQRF Fox_Affiliate ntsc;WQRF:67250:TV|NTSC:V:0:301+101=2:300=@4:0:0:30060:96:96:0 But, obviously all on the same line. I think this is probably an issue with streamdev rather than pvrinput as it works with Vomp happily. I need it to detach and change channel in order to trigger the external channel changer script. pvrinput does its channel settings (this includes executing the externchannelswitch-script) inside its function OpenDvr() while the encoder is still stopped. The settings will only be done if the bool ChannelSettingsDone is false. This bool is always false at first plugin start. I guess this is the reason why your channel settings were done once: Jun 7 19:13:24 oac vdr: [8795] entering cPvrDevice::OpenDvr: Dvr of /dev/video1 (PVR500#1) is closed Jun 7 19:13:24 oac vdr: [8795] entering cPvrDevice::CloseDvr: Dvr of /dev/video1 (PVR500#1) is closed Jun 7 19:13:24 oac vdr: [8795] cPvrDevice::ResetBuffering(): tsBuffer prefill = 314524 for /dev/video1 (PVR500#1) Jun 7 19:13:24 oac vdr: [8795] channel is television.

There are no debug messages from pvrinput's SetChannelDevice() or ProvidesChannel(), so vdr never calls these pvrinput functions - although a channel switch for a pvrinput device is requested. But why? I have no idea. It works for you with vomp. It worked for me with streamdev when I tested this last year. But I had only streamdev-server running and used vlc to switch channels.

But don't tell anyone.. :-) An example of the channel list is: 2-WTTW PBS_Affiliate ntsc;WTTW:67250:TV|NTSC:V:0:301+101=2:300=@4:0:0:30020:32:32:0 3-WREX NBC_Affiliate ntsc;WREX:67250:TV|NTSC:V:0:301+101=2:300=@4:305:0:30030:48:48:0 4-WTVO ABC_Affiliate ntsc;WTVO:67250:TV|NTSC:V:0:301+101=2:300=@4:0:0:30040:64:64:0 5-WIFR CBS_Affiliate ntsc;WIFR:67250:TV|NTSC:V:0:301+101=2:300=@4:0:0:30050:80:80:0 6-WQRF Fox_Affiliate ntsc;WQRF:67250:TV|NTSC:V:0:301+101=2:300=@4:0:0:30060:96:96:0 But, obviously all on the same line. I think this is probably an issue with streamdev rather than pvrinput as it works with Vomp happily. I need it to detach and change channel in order to trigger the external channel changer script. pvrinput does its channel settings (this includes executing the externchannelswitch-script) inside its function OpenDvr() while the encoder is still stopped. The settings will only be done if the bool ChannelSettingsDone is false. This bool is always false at first plugin start.

Maybe a streamdev developer reads this and has an idea or can explain possible interactions between streamdev-client, vdr and a receiving device. I think this is a streamdev issue not a pvrinput one, as if I change from channel 5 to 6 on the remote streamdev client it will continue to display channel 5. If both my tuners are busy then it will lock to channel 5 on my backend if I test it with xineliboutput. Not lock to channel 6. I had a look at the http::// streamdev playlist settings and it sees different channel pids. Streamdev to vlc would work as it breaks the streamdev connection when you change channel. But streamdev-server to streamdev-client doesn't seem to break the connection, just request a second channel as it releases the first. ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
Re: [vdr] Streamdev to Streamdev with PVRInput card
Hi Rob, I also don't think its a pvrinput problem because: streamdev doesn't query for a new device if the current and the next channel has the same transponder. This is checked via the following define: channels.h:#define ISTRANSPONDER(f1, f2) (abs((f1) - (f2)) 4) //XXX All the channels in channel.conf have the same frequency, so streamdev only changes the receivers but doesn't query for a device. I havent understand exactly what you are doing. Do you use an analogue input (like scart) of the pvr500 card and the channel switch script changes the channel of another device ? If so, i could imagine the frequency in channels.conf doesn't matter and you could simply modify the frequencies.

Re: [vdr] Streamdev to Streamdev with PVRInput card
Hi Rob, I also don't think its a pvrinput problem because: streamdev doesn't query for a new device if the current and the next channel has the same transponder. This is checked via the following define: channels.h:#define ISTRANSPONDER(f1, f2) (abs((f1) - (f2)) 4) //XXX All the channels in channel.conf have the same frequency, so streamdev only changes the receivers but doesn't query for a device. I havent understand exactly what you are doing. Do you use an analogue input (like scart) of the pvr500 card and the channel switch script changes the channel of another device ? If so, i could imagine the frequency in channels.conf doesn't matter and you could simply modify the frequencies. ok, that makes sense to me... I am using a brain dead cable box which are being given away by the cable company, these have RF out only on either US Channel 3 or 4. I have two of these wired together with a signal combiner (To minimize the side band intererence). For pvrinput they all need this frequency.. (now at Ch 4), if device 1 is busy I hacked pvrinput to flip the frequency to channel 3, but streamdev would never know this. Can we put a check in streamdev to check if it's a pvrinput device and recall even if the frequency is the same? ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
