does VBrick streams support include MPEG4 via RTP ??

Postby stafforj » 15 Nov 2004 15:53

Hi,

Release note for 0.8 says "VBrick streams fully supported" does this include MPEG-4 via RTP ?


------------------------

I am trying to use VLC 0.8 to play a multicast RTP mpeg4 stream from a Vbrick encoder, and I am getting nowhere.

If I use RTP:://@236.1.1.1:1234 as source instead then I get
"No RTP header detected" - due to the RTP payload type being 96 which VLC doesn’t handle.

If I use UDP:://@236.1.1.1:1234 then I get:

./vlc0.8 -vvv --vout fb --fbdev=/dev/fb0 udp://@236.1.1.1:1234 --width 480 --noaudio

mpeg4 over rtp is unplayable without the acompanying .sdp file. This is perhaps gotten through sap for multicast streams.

The Vbrick encoder makes the sdp available via http, or if need be I can store it in a file.

So assuming the sdp is available, how would this be provided to VLC ?

Has anyone has played MPEG4 via RTP ?

give VLC the link to the SDP, or get the RTSP link to VLC. Both will work.
Don't use PMs for support questions.

OK, I tried using the SDP via HTTP, and heres what happened, it fetches sdp ok, but end result is still 'garbage at input'.

You don't have rtsp support compiled in. compile with livedotcom support.
Don't use PMs for support questions.

Somehow the sdp seems very invalid. Perhaps we could have a look at it?

and an even better look at the log tells that the sdp is there allright, but somehow the wring module handles it.

Try this:
./vlc0.8 -vvv --vout fb --fbdev=/dev/fb0 http/livedotcom://172.63.200.7/vbs1d1.sdp --width 480 --noaudio

Sigmund,

Many thanks, that has fixed it, :)


....However, although it plays ok for the first few minutes, it then starts to get jerky/breakup and 'TaskInterrupt' starts appearing. :(
('TaskInterrupt' is printed from function TaskInterrupt() in livedotcom.cpp).
I'm not quite sure what the TaskInterrupt implies however.

It seems the longer it runs the worse it gets.

We currently have Vbrick encoder set to produce 12.5 FPS, and 512Kbps


The CPU usage observed via top, is around 50%
(cpu is a ppc405H, running at 200mhz)


Trace is as follows:

We will try to implement proper autodetection for steams like yours in time for next release.

TaskInterrupt means that the livedotcom library goes too long without actually getting anything to do. This usually imply that no data is arriving at the network card. But I guess in your case it could also happen because the cpu is overloaded or thread scheduling is horribly bad (last two are only suspiccions though, I haven't thouroughly checked that these are possible causes)

I found out why we got broken video after a few minutes playing, our system clock was running 0.625% slow. ie after 4 minute clock had lost a second!!

This was because on our custom board, the clock input to the PPC405 CPU goes through a spread spectrum device, which only speads the frequency downwards! The device gives a 1.25% frequency spread, resulting in an average 0.625% reduction in the clock rate. After we adjusted our clock dividers vlc plays fine.

However, I am left wondering why vlc could play MPEG4 TS over raw UDP steaams sucessfully with the inaccurate clock, but not RTP.
Does this mean that if RTP MPEG4 is left playing for a long time )ie months) on a standard PC, then clock drift could result in problems like we saw ?

I think it is because timestamps in mpeg2-ts are relative to a system clock that is embedded in the stream, while rtp use rtcp to create a mapping from stream-time to wall-clock-time. I think this actually show how mpeg2ts is better designed than rtp, and at least it's designed for this sort of application.

I've tried to read a RTP or RTSP stream from a pocket with VLC. But I could not. I believe it's not possible yet due to the lack of the livedotcom library on Pocket PC.

"The CPU usage observed via top, is around 50%
(cpu is a ppc405H, running at 200mhz) "

Did you manage to read a RTP stream from a pocket PC ?

If yes, could you give me some informations about the way you have done it (compilation, OS, source modifications ...)

It would be very helpful,

Thanks

Ahh wow u have a Brick we just bought a few 2! They are gorgeous!

Just out of curiosity, why don’t you want to use VBrick’s StreamPlayer?
