RTSP mpeg4 from Axis camera - capture to file - issue at 55s

Postby lerxst » 19 Jan 2007 19:33

Hello...
I've tried this on Windows, Linux and OS X(primary platform) and have an interesting error I'm encountering.

We're using a newer Axis webcam, and have been trying to capture the stream to a file.

We are doing this:
1) open VLC
2) preferences, select Input/Codecs, Demuxers, RTP/RTSP and check advanced box
3) check Use RTP over RTSP (TCP) client port -1
4) File | Open Network
5) click http/ftp/mms/rtsp and we are using rtsp://camera.ip.addr.com/mpeg4/media.amp
6) select target file (/Users/jre/Desktop/vlc-output.mp4) and set encapsulation method to MPEG4
7) click OK, OK again and it starts

It works GREAT if we capture less than 55 seconds.
RIGHT AT the 55 second mark, things go horribly wrong.

I ran it from the command line with verbosity, and here is the output. Note that I marked at 50 seconds and 55 seconds and when I hit Control-C a bunch of times to stop the program. If we don't run it from the command line, a Force Quit (OSX), process kill (linux), or task-kill AND reboot (windows) is necessary before it will work again (windows platform doesn't cleanly work again if a reboot doesn't happen...).

I need some ideas! and help! :)

Here is the dump:

Anyone got any clues? we would like 10-15 minutes of capture to the file, and instead can not even reach the 1-minute mark....

Thanks!

it seems related to an issue i had with a similair setup.

for an art project we want to receive/capture/manipulate/analyze/record/project etc.. a high resolution rtp/rtsp stream from an ip camera (which is way cooler than yours... :)

the quad G5 we currently develop on, is reasonably capable of handling a 1280x720 @25fps stream in mjpeg comression (±70%). depending on ligh and detail this results in 2 to 4Mb per second of data.

but anything higher will choke something somewhere in the system. didn't have time yet to see if it's quicktime, or maybe udp/tcp network-buffers going nuts...
i did do some tests with VLC, in order to see if it were an option to 'use' code from the VLC source, so we could bypass quicktime, but i ran into the same problem...

quicktime would just display a white frame, VLC will crash at some point..

didn't have time to create a clear, reproducable crahs situation yet, but i have the feeling it's maybe somewhere in the network-layer in osx..

anyway, try lowering the resolution and/or datarate. see if it still happens. this could give VLC developers maybe some clue.

btw; this 'cooler than yours' camera is the Elphel 333. (http://www.elphel.com)
it's really an amazing device. up to 3 Megapixels (@±12 fps) or up to 90fps on lower resolutions. and hard- and software are opensource...


cheers :)

btw;

a patched mplayer the elphel developers supply can handle high datarates with no problem on a thinkpad T42 running debian..

Other options?

Well, I don't think it's a /data size/ issue... my dual-proc G4 can't even do it.
But on ALL machines, including the windows computer, the stream basically plays forever in Quicktime.

So basically, I need to get this project done, and VLC seems not to be able to stream capture more than 55 seconds of this type of stream... but Quicktime plays it forever... no issues.

Ideas?

Wow... even playback doesn't work...

Ok. here's something interesting. Playback even stops at 55 seconds, when I'm not capturing the stream to a file.

Does this mean RTSP over TCP is broken in VLC?

seems like some timeout issue from the camera's side, (and no keep-alive from VLC) . the GET_PARAMETERS request doesn't even seem to me supportes by the camera:

maybe interesting to look at output of TCPFLOW

I was having the same 55sec timeout problem using an Axis 241SA Video Server. I found the solution in the Plain Config.

System Options > Advanced > Plain Config > Network

Scroll down to the RTSP section and the default timeout value on mine was 60 seconds. I set it to zero and now VLC plays just fine.

I am experiencing the occasional pause in audio (video is fine).

Where is the "System Options > Advanced > Plain Config > Network " settings? Is this in the Axis Video Server or the VLC Player?

I am having the same problem using the VLC player with another video server. Is there a config in the player to disable the timeout ping by the player? I could not find anything using the GUI preferences menus in the VLC player. However, I see the code is retrieving a timeout value from somewhere as below:

Taken from live555.cpp:
---------------------------------------
*****************************************************************************
* Play: starts the actual playback of the stream
*****************************************************************************/
static int Play( demux_t *p_demux )
{
demux_sys_t *p_sys = p_demux->p_sys;

if( p_sys->rtsp )
{
/* The PLAY */
if( !p_sys->rtsp->playMediaSession( *p_sys->ms ) )
{
msg_Err( p_demux, "RTSP PLAY failed %s", p_sys->env->getResultMsg() );
return VLC_EGENERIC;
}

/* Retrieve the timeout value and set up a timeout prevention thread */
#if LIVEMEDIA_LIBRARY_VERSION_INT >= 1138089600
p_sys->i_timeout = p_sys->rtsp->sessionTimeoutParameter();
#endif
if( p_sys->i_timeout > 0 && !p_sys->p_timeout )
{
msg_Dbg( p_demux, "We have a timeout of %d seconds", p_sys->i_timeout );
p_sys->p_timeout = (timeout_thread_t *)vlc_object_create( p_demux, sizeof(timeout_thread_t) );
p_sys->p_timeout->p_sys = p_demux->p_sys; /* lol, object recursion :D */
if( vlc_thread_create( p_sys->p_timeout, "liveMedia-timeout", TimeoutPrevention,
VLC_THREAD_PRIORITY_LOW, VLC_TRUE ) )
{
msg_Err( p_demux, "cannot spawn liveMedia timeout thread" );
vlc_object_destroy( p_sys->p_timeout );
}
msg_Dbg( p_demux, "spawned timeout thread" );
vlc_object_attach( p_sys->p_timeout, p_demux );
}
}
return VLC_SUCCESS;
}






This is an urgent issue for my customer, so any help would be appreciated.

Thanks,
Larry Deaton

Re: RTSP mpeg4 from Axis camera - capture to file - issue at 55s

Postby glebfrank » 03 Feb 2009 11:21

OK, I'm seeing what appears to be the same issue - but only on the Mac. I'm using VLC 0.9.8a. Basically, the first time VLC sends a GET_PARAMETER request to the server, I get tons of "Discarding interleaved RTP or RTCP packet" messages, and have to force-quit the VLC process... Works like a charm on Linux. Thoughts?

If vlc sends GET_PARAMETER on 0.9.8, then the server supports that message. The only reason that i see that can cause this, is simply that the AXIS camera responds incorrectly and the live555 (the component we use for RTSP) starts ignoring the data.

Note how the "Discarding" messages in the debug logging posted above don't start with: "[00000###]". Historically, AXIS isn't known for the fault tolerant RTSP implementation, but this might be a bug in live555 as well.
Don't use PMs for support questions.
