ffmpeg related issue

Question

I am using the following command for video conversion using ffmpeg :-

ffmpeg -i 'in.wmv'  -s 1280x720 -b 256 -ar 44100 -ab 64k -ac 2  'output.mp4'

and it is working fine.

But the problem is that when i am playing the converted file into the totem player then in properties section "audio bitrate" and "video bitrate" is being display "N/A" whereas "audio bitrate" and "video bitrate" must be 256 and 64k respectively.

Thanks in advance..

Answer 1

The problem is that your -b option is 256. -b is used to set the video bitrate. you should set it to 64k if that's what you want. The audio bitrate is set with -ab, which you are setting to 64k...

And, btw, -ar defaults to 44100 and -ab defaults to 64k so you don't need to pass those arguments if you don't want to.
