Memory usage increasing when rtp streaming without mux

[vukia]

Hi all,

I've tested this issue from 2.0.x up to 2.1.3,
I use vlm to create a rtsp streaming, the source is a h.264 rtsp ip camera.
When didn't set any mux, after several days(usually 2 days it will happen), it will suddenly increase memory usage from 30mb to 400mb and continuing increasing until crash.
If I set the rtsp streaming "mux = ts", it works normally over 40 days.

Thanks any help, because I need camera sound, but ts can't

I've trace the rtp.c source code, it seems use "es" muxer if no mux has been set.
Besides, even the memory is increasing, the streaming is working and cpu usage doesn't increase work load, just memory problem.
If I try to lookup source codes about es muxer, which file should I notice?
Thanks alot

Err what? Without muxer, the RPT output does not use a muxer at all, period.

I didn't found any error, function is working, but the memory suddenly increasing 400k~800k per second after unknown condition happen.
Usually race this condition after two days.
The same environment but set "mux=ts", didn't have any problem.
I'm tracing rtp.c files now, hope I can find something there

I'd guess some queue, possibly the RTP output thread, is filling up faster than it gets flushed.

Thanks for your reply,

I traced the rtp.c source code, maybe this issue is in p_buffer block release and packetize:

if (id->b_first_packet)
{
id->b_first_packet = false;
if (!strcmp(id->rtp_fmt.ptname, "vorbis") ||
!strcmp(id->rtp_fmt.ptname, "theora"))
rtp_packetize_xiph_config(id, id->rtp_fmt.fmtp,
p_buffer->i_pts);
}

if( id->rtp_fmt.pf_packetize( id, p_buffer ) )
break;

block_Release( p_buffer );
p_buffer = p_next;
}

This issue seems still exists in the latest version, does anyone can give me some hint to solve this problem?
Because if I set mux to ts, the audio from IP camera (mlaw) is gone....
Thanks for any help~
