[FFmpeg-user] Problem decoding h264 on newer versions of ffmpeg

Thanks Carl, i can confirm that with `-disable-bsf=extract_extradata` i'm
able to decode and play the video file correctly.
Still, the file was extracted from an RTSP session and when i try to use
ffplay directly against the RTSP server is still failing to detect or
decode the h264. The audio is played correctly.
The SDP looks good, and it detects the stream as h264, but it seems cant
detect codec parameters .
Any hint on this?
Here is the log:
