I am using the following command for video conversion using
ffmpeg and it is working fine:
ffmpeg -i 'in.wmv' -s 1280x720 -b 256 -ar 44100 -ab 64k -ac 2 'output.mp4'
However, when I am playing the converted file into the totem player then in properties section audio bitrate and video bitrate are being displayed as N/A. The audio bitrate and video bitrate must be 256 and 64k respectively.
