Hi.
I'm trying to open an external RTSP server by using FFMPEG.
FFMPEG connects to RTSP, but then shows the following errors, and the
resulting file is 160 bytes in length:
ffmpeg -i rtsp://192.168.253.101:7070 test.mp4

VLC, with it's Live555 connector, works just fine and shows the video.
In the VLC messages log, FFMPEG shows same warnings (about not complete
headers) and also a lot of "header damaged warnings":
avcodec warning: cannot decode one frame (44 bytes)
avcodec warning: header damaged
([EMAIL PROTECTED])
But it still works.
Any idea why FFMPEG can't handle this stream (while VLC can, using same
libavcodec to decode the stream)?
Thanks in advance.
