[FFmpeg-devel] Fwd: Transcode VP8 RTP stream to mpeg1 video frames.

[Ajay Choudary]

Hi Ronald,

Thank you for your quick response, i was new to ffmeg mailing lists.
I tried with sdp_file option as shown in below command,
# ffmpeg -vcodec vp8 -sdp_file file.sdp -i rtp://192.168.1.93:15000  -f
mpeg1video -b: 400k -r 30  http://192.168.1.11:8082/url/640/480/

*Unrecognized option 'sdp_file'.*
Error splitting the argument list: Option not found.

i searched ffmpeg source code, no where they are processing -sdp_file
option.

Thanks & Regards for your valuable time.
