-dcodec copy doesn't copy dcodec

[dave rice]

If I specify -vcodec copy -acodec copy -dcodec copy, only vcodec and acodec are copied. If I use -c: copy (as directed here ​http://ffmpeg.org/ffmpeg.html#Stream-specifiers), I also get no dcodec in the output.

ffmpeg -i MPEG2_8.mov -vcodec copy -acodec copy -dcodec copy MPEG2_8copy.mov

You have to specify -map 0:2 (or similar options) to copy the data track into the (mov) output file.

As you know, this currently does not work currently due to ticket #236.
