[Live-devel] openRTSP h264 decoding

Mon May 30 03:07:06 PDT 2011

Hello, first of all thank you all for maintaining this forum so active

I am using openRTSP to recieve a stream with a .sdp this stream contains
video and audio streams, but I´m only interested in the video, which is
encoded with h264, when i am trying to decode with ffmpeg I obtain NAL
errors.

I also tried to write the stream in a file with FileSink and open it with
vlc or ffmpeg but i obtained the same result,

ffmpeg -i "video-H264-1"
video-H264-1: Unknown format

I saw that H264VideoFileSink put the header 0x00000001 in each frame but
seems that don´t work properly.

I read the FAQ and some post in the mailing list and I saw similar problems
in other persons, Can someone help me?

Thank you very much.
