MPEG4 SP RTSP streaming......

[shivaprasad]

Hi,

I am running MPEG4 RTSP streaming application on iMX51 based platform. For encoding I am using iMX51 Hardware encoder.
My iMX51 platform act as RTSP stream server & VLC in PC as client.
I am facing following problems while using vlc-1.1.7-win32 as client,
- I am getting green patches while displaying the streamed video on VLC.
- Displayed video is very slow.
- Video is jerky

While using vlc-0.8.6i-win32 as client,
- Video playing is bit faster compared to vlc-1.1.7
- Drops lot of frames(late picture skipped), which is not observed in vlc-1.1.7

I haved tested same streaming framework on iMX27 based platform, where MPEG4 BP video is used for streaming.
Which is working fine with all vlc versions.

My connection parameters given below,
m=video 0 RTP/AVP 96
a=rtpmap:96 MP4V-ES/90000
a=fmtp:96 profile-level-id=1;config=000001B001000001B59088000001000000012000C8888007D0B042414103

Please provide the clarifications..
1. VLC supports MPEG4 SP streaming?
2. Connection papameters are OK?
3. MPEG4 SP frames are not having Visual Object Sequence & Visual Object compared to MPEG4 BP. Is this expected behavior?

Hi,
I am able to solve MMPEG-4 streaming issue. Problem was MPEG-4 hardware encoding API's taking too much time to encode.

Im able to play streamed video on vlc-0.8.6i version properly. But while taking snapshot of streamed video, vlc application crashes.

In vlc-1.1.7 version, I am not abled to play streamed video. Lots of frame skipping exists in VLC side and I am not getting expected framerate at VLC side.
In vlc-1.1.7 I can take snapshot(But no use, since playing streamed video not working properly).

Please suggest me the solution.

Regards,
