     117If we want to re-encode just the video streams, but copy all the other streams (like audio, subtitles, attachments, etc), we might use something like this: 
     118{{{ 
     119ffmpeg -i input.mkv -map 0 -c copy -c:v mpeg2video output.mkv 
     120}}} 
     121It will tell ffmpeg to: 
     122- read the input file 'input.mkv' 
     123- select all the input streams (first input = 0) to be processed (using "-map 0") 
     124- mark all the streams to be just copied to the output (using "-c copy") 
     125- mark just the video streams to be re-encoded (using "-c:v mpeg2video") 
     126- write the output file 'output.mkv'
