Hi All,
I am trying to stream media to play it on android using RTSP/RTP. I am
using ffmpeg and ffserver for the purpose. I am trying to do that for quiet
some time now but still unsuccessful.
Now I found that Wowza server streams file that plays fine on my device "
rtsp://ec2-174-129-153-104.compute-1.amazonaws.com/vod/mp4:BigBuckBunny_175k.mov
"
NOTE: My stream also does not play well with ffplay or vlc player. These
players render either audio or video depending on the ffserver config.
I did packet capture of my stream and the stream that is sent by the wowza
server and noticed that there are minor differences in the SDP sent by
those.
Major Difference
Audio: parameter "config=" and the stream bit rate are different
Video: parameter "profile-level-id=" is missing in SDP sent by FFMpeg
Could anyone please suggest correct parameters for my stream to work from
ffmpeg. I am currently using "SVN-r24078"
SDP stream that works: (sent by Wowza server)

I use ffmpeg to input stream to ffserver...and ffserver to RTSP stream to
player.
