If you have issues with ffmpeg, espeically potential bugs, kindly try a recent version first. In this case, it's likely a usage info, so old version forgiven, as far as I am concerned. ;-) > One of the audio streams is descriptive audio for the hearing impaired. > Now I'd like to mark it as such in the newly created mkv file. ffmpeg > only flags the subtitle stream as hearing impaired, but this was marked > in the input file already... > > Does anyone know how to specifiy the stream that should be marked? > I'd like to mark stream 0:2.

As Peter hinted, the "-disposition" option may be the correct one for you. If I use $ ffmpeg [...] -disposition:a:2 hearing_impaired [...] ffmpeg marks the third output audio stream as such. Do give that a try. (At least ffmpeg says it applies this to the output. I can't find any indication in the actual output file though.)
