I'm new for video streaming but I'm really willing to work with that tool.
I use Ubuntu 12.11 and VLC media player 2.0.8 Twoflower (revision 2.0.8a-0-g68cf50b)
I have an experimment with rtpplay tool and VLC.
Rtpplay tool sends rtp packets to VLC: ./rtpplay -T -v -f /home/xxx/file 10.10.133.143/15028
VLC receives the packets and stores it as mp4 file: vlc --file-logging --log-verbose=2 --logfile=/home/xxx/vlc_log_receiving.txt file:///home/xxx/sdp.sdp --sout '#standard{access=file,mux=mp4,dst=/home/xxx/result_4.mp4}'
I have the following sdp file:
v=0
o=- 15484852015065732607 15484852015065732607 IN IP4 ekaterina-P5GZ-MX
s=Unnamed
i=N/A
c=IN IP4 10.10.133.143
t=0 0
a=tool:vlc 2.0.8
a=recvonly
a=type:broadcast
a=charset:UTF-8
m=video 15028 RTP/AVP 96
b=RR:0
a=rtpmap:96 H264/90000
a=fmtp:96 packetization-mode=1;profile-level-id=4d401f;sprop-parameter-sets=Z01AH+jAIAJNCAAAAwAIAAADAYB4wYjQ,aOlzLIA=;
So the problem is the following:
VLC player receives less bytes than rtpplay sends. As the result I have:
VLC media player 2.0.8 Twoflower (revision 2.0.8a-0-g68cf50b)
[0x8e36908] main libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface.
[0xb5400618] main input error: ES_OUT_RESET_PCR called
MultiFramedRTPSource::doGetNextFrame1(): The total received frame size exceeds the client's buffer size (65536). 1391 bytes of trailing data will be dropped!
From the vlc log file we can see that buffer is too small for receiving some frame, but it is rised once it happends.
I tried to send mp4 file from VLC to VLC. The result is the same.
The log file is the following:

What can be the problem?
Sorry if I miss some important information. Let me know in this case.
I tried to find the solution of that problem in the internet but I haven't any success...
