[FFmpeg-devel] RTP input stream blocks ffmpeg

[Yohann Martineau]

hello,


I'm trying to transcode a video stream sent over RTP from h263 to 
mpeg2video, and to forward this transcoded stream over RTP.
The payload type of my h263 stream is h263 and the payload type of my 
mpeg2video stream is mpeg2-ts.

I'm using latest svn version.

The following command gets stuck:
$ ffmpeg.exe -i rtp://192.168.1.45:10002

I try to get codec information from this command line. But I have 
nothing on my console.

I thought it would give me a timeout or a message stating that no packet 
has been received or any error message.

when I try with http, I have a timeout:

$ ffmpeg.exe -i http://sdkjfgsdkjf

http://sdkjfgsdkjf: I/O error occured
Usually that means that input file is truncated and/or corrupted.


Am I missing something obvious ?

Should I report a bug ?


Knowing that RTP is a realtime transport protocol, I think a timeout 
would be nice.

Sorry if I'm on the wrong mailing list, I tried on ffmpeg-user 
yesterday, bug got no response.

Thanks,
