[FFmpeg-user] ffmpeg on Ubuntu 12.04 to Wowza server.

[Leonard Bogard]

I wasn't able to drop .mp4 from the entrypoint because the embeded player
is hardcoded to .mp4 but I did try -f flv and it worked.

Doesn't changing it to -f flv degrade the video quality be dint of the
encoder it uses?

And, is it that the rtmp protocol doesn't like .mp4 container?
