[FFmpeg-user] baseline profile not getting activated in ffmpeg

[Susheel Tickoo]

Hi all,

Is there any one woh is able to do this in c code. If yes please share the
settings that can activate baseline video creation in ffmpeg.
As right now i am not able to activate the baseline profile through c code.
I am getting close enough to conclude that this can be a bug in ffmeg code.
