[FFmpeg-user] FFMPEG Video Conversion

[Palaniappan N]

Hi Reindl,


As suggested, We did uninstalled the previous version 0.10.3 and followed
the link https://ffmpeg.org/trac/ffmpeg/wiki/CentosCompilationGuide to
Install FFMPEG.

Now, when we try to check the FFMPEG version we get the following output

# ffmpeg -version

Also When tried video conversion, the output is as follows

I am not sure about  "b:a 720" as it was specified by our developer.
