Re: [linux-dvb] How do you stream the entire MPEG-TS with dvbstream?

If I do something like this: dvbstream -f 226500 -gi 16 -bw 7 512 650 Then it works fine, I get video and audio on the other PC and about 500kB/sec network use, but if I do this: dvbstream -f 226500 -gi 16 -bw 7 8192 Then the network use goes up to 1.7MB/sec but the picture and sound arrive corrupted, as if I have extremely bad reception. Using an old version of dvbstream with a Hauppauge Nova-T this works fine, except in that case I have 3MB/sec of network traffic with the same channel. It's almost as if the latest version of dvbstream doesn't correctly capture the whole MPEG-TS stream from the card. Has anyone else gotten this to work? Thanks, Adam. with the same drivers and a different version of dvbstream? In any case you should always try a fresh cvs checkout of dvbstream. A simple test you should run is this: dvbstream -f 226500 -gi 16 -bw 7 -o 8192 dump.ts and try to play the dump.ts from another terminal. If you see corruptions then report back, please.

No luck yet, although the h261 codec announces the frame size (apparently for cellphones) and refuses to decode further. What to do next? if in the SDP of the broadcast transmission there's some kind of configuration (base64-encoded) string (generally known as extradata ) then you won't get ffmpeg (or any other decoder) decode the raw ESs without passing the extradata before feeding it the payloads. This is the common practice for that abomination that is RT[SC]P, which encourages this splitting between extradata and payloads even for formats that may have headers in-stream like H26x and Mpeg4.

I'm lookig for a way to recognize the type of a video-frame in MPEG-2 (I.P or B) to create smooth transitions between video files, without having to decode the whole frame. I looked through the MPEG-2 TS and PES definitions, but all i found was a splicing_point_falg in the TS Adaptation Field. Unfortunately the hardware-encoder i'm working with doesn't seem to set these flags.

[linux-dvb] Re: [dvbtools-devel] dvbtune-0.5 inverts diseqc pol and band bits
Zoilo Gomez wrote: dvbtune-0.5 source apparently contains a bug where it inverts both the polarization and high/low band bits in the diseqc command ... as I cannot find any info on this anywhere, I am posting my results here. I discovered this while using a KNC1 DVB-S card to compare diseqc handling with VP1034 (because diseqc is not (yet) working on my VP1034). I am using a Spaun 17089-NF 16-input switch (4 sats) + 8 outputs, which supports up to Diseqc 2.0. First I got confused, because the Mantis driver simultaneously uses the old 18/13V+22kHz method to control polarization and band, as well as the Diseqc method. So for a while I believed that Diseqc was (partially) working, until I found out that in fact 18/13V+22kHz seems to be responsible for the (partial) job! As a result of no Diseqc-functionality on VP1034, it seems that with VP1034 on my switch, sat-selection is always fixed to sat=1 (makes sense, = the first 4 inputs, which happens to be Hotbird 13.0E in my setup), however input selection from the 4 feeds V/H and H/L works fine and correctly, although based on 18/13V+22kHz. When I compared this with my KNC-1 DVB-S card (to find out why Sat-selection is not working with VP1034), I found that with KNC1, Sat-selection does switch to Sat=2 (so it must be using diseqc), but polarization and band-selection were inverted ... So when I issued the following command: dvbtune -D 2 -f 10832000 -p H -s 22000 I found that it was actually selecting sat=2 pol=V band=H (e0 10 38 f5= switch input 7), instead of sat=2 pol=H band=L (= switch input 6 / e0 10 38 f6). The Diseqc-specs at http://www.eutelsat.com/satellites/pdf/Diseqc/Reference%20docs/bus_spec.pdf (table on page 13) confirm that dvbtune is in fact sending the wrong command. With a patched dvbtune (pol-bit and band-bit both inverted) it works OK, and is also according to the Eutelsat specs. Hope someone benefits from this. Z. nice, but i don't see the patch, but I wonder how I can have been using my sat switch for years ___ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb

Re: [linux-dvb] DVB-H and dvbnet / MAC-broadcast address
Dietmar Zlabinger wrote: Hi, I am looking for help on receiving DVB-H. I get to the point where the encapsulated IP is attached to a network interface (as dvb0_0 using dvbnet -p portnr). At this stage I am able to dump the UDP-packets received using tcpdump. But I am not able to get that IP-multicast into VLC. I believe the problem is related to the fact that normally IP-multicast uses the Ethernet broadcast address (ff:ff...) while in dvb-h the destination mac is (partly) replaced by the dvb-h time slicing information . Therefore the traffic is only received by the network interface when it is in promiscuous mode (when using tcpdump), but not when a normal program (like vlc) is trying to get multicast frames out of it. My idea then was to modify dvbnet so that it replaces the broken ethernet destination (is contains timeslicing-infos) by ff:ff so that it goes through the network interface. But the actual code of dvbnet does actually not handle the received data, the only thing that program does is some ioctl(fd_net). Any idea who I could get the ethernet-multicast out even when the destination mac is wrong? Any idea how I could modify (the kernel) so that I could overwrite the faulty mac? I could not find any description on how to receive dvb-h on the web. The are some mailing on how to find SDP files, but that was not such a big thing (dvbsnoop -b pid ..). Thanks for help, Dietmar premitting that I have very little confidence with networking in general... if you run $ ifconfig dvb0_0 ip/mask promisc up $ route add -net 224.0.0.0/4 dev dvb0_0 you shouldn't need to tamper with the MAC addresses. You can also use smcrouted to re-route the tuple src_ip-dest_ip from dvb0_0 to eth0 (although I find it annoying having to know the source ip).

Sorry, I haven't had the time to chase this one up, but I haven't had a peep out of my T-1500 since I tried using dvbtune instead of the dvb-apps tools. I had no luck at all with dvbtune, and now I can't get a picture out of it. The behaviour is very strange - doing all the things that used to work perfectly - scan gives me all the channels I would expect, tzap gets a lock, and dvbtraffic is reporting a plausible amount of data.

I'd like to be as efficient as possible, so I took at look at the splice() function implemented as of Linux 2.6.17 and it looks promising as for most cases I could splice() the data from the dvr device directly to the socket. There might be two problems though: - Is there a splice() patch for the DVB drivers? http://lwn.net/Articles/178199/ suggests that doing such a thing is possible, but I havn't found an implementation yet. - Is there a way to do a read() from the dvr device without removing the data from the queue (i.e. an equivalent for recv()/MSG_PEEK)? I'd need that to know the PID of the the TS packet. Thanks for any hint... Cheers, Johann already done: dvbstream from cvs can already stream to multiple unicast/multicast/file streams repeating pids to each of them, and it's very lightweight (although I have to admit it's a bit untidy). http://sourceforge.net/projects/dvbtools ___ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb

Test 1: tzap -r TVE 1 cat /dev/dvb/adapter0/dvr0 /tmp/tv.mpeg mplayer /tmp/tv.mpeg -- Works for some channels, doesn't work for others (pixels, glitches, bad audio, etc.) [Just for testing -not related with dvb, but with dvb+mplayer integration- I've tried with cat to a file, cat to named pipe and directly with mplayer /dev/dvb/... , with the same results] maybe due to bad reception Test 2: mplayer dvb://TVE 1 -- Works but, for some channels (the same that don't work with Test 1, sometimes, it doesn't work the first time [mplayer complains about a read error, ^c and launch again and 90% of the time it gets OK... maybe something related to tunning timeouts/issues?]) maybe. I hope I won't have to increase the timeout to +INF :( So, the question is (I guess the answer is obvious at this point): the mpeg stream that one gets from dvr0 cannot be passed to mplayer? uhm, if not how are you supposed to play it? :) how do you believe that mplayer plays dvb:// streams? depends on the channel? maybe depends of what information(s) that channel is sending? (epg, subtitles, multiple audio?) depends on the signal? broken streams will lead to broken playback, as is to be expected I've tried those examples (zap/cat) since they appear in the wiki as simple test tools, but maybe I'm assuming too much? no Should I use other tools like dvbrecord (I've just discovered it)? Or thinking about a simple pvr only with simple filters ala *nix style in this case [dvb, TS/PS, etc.] is not possible? it _is_ possible, provided that the drivers provide a stream as little damaged as possible. BTW, tzap+cat or dvbstream are the most reliable way to get your simple pvr working ___ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb

TS is for broadcasting, and PES is for recording. is this just a personal opinion? me, actually i can see a great move toward TS also for storing.. i think about the HDV storage cassette; there is a TS inside the tape. the forecoming blu ray technology has a TS inside the optical diskette (but i have to say there's a PS inside the HD-DVD disk; who's going to win, i dont know..) really? I thught it would use TS, too. Do you have any specification? IMHO i believe that in the medium term there's no space for two different storage standards: to hassle to maintain both up to date the TS is going to succeed because: - it's where all the development for newer services is going to be done - you can store the broadcast straight on the disk - the bucks per storage byte index is going lower and lower.. bye andrea venturi agree, and the overhead of ts over pes is going to be insignificant with the typically used bitrates.

Hmm, I would have expected that information to be in there somewhere.
The decoder should be able to detect the encoding of the data stream
by itself, without the application having to tell it what the data
actually is.
Klaus
from an application point of view it makes more sense to follow the model:
decode_pat()
foreach program
{
decode_pmt() == identify the codec used by the stream_type
}
Moreover, the pes headers in mpeg2 are already overbloated with 90% of
useless crap;
adding more stuff would have been a bad choice, IMO.

An application can simply try DMX_PES_OTHER first and if

Mythtv does it this way afaik.
it seems doable. I'll have a try modifying dvbstream (and mplayer
which is the same) and try to see what happens.
