 When I try to convert a mkv file and want to copy the subtitles too it
 gives me the following error:
 track 2: could not find tag, codec not currently supported in container

 FFmpeg commandline:
 /Users/atarikid/Desktop/ffmpeg -i /Volumes/Data/Movies/Homeland.mkv -c:a
 aac -c:v libx264 -strict -2 -c:s copy /Users/atarikid/Desktop/test.mp4

 Could not write header for output file #0 (incorrect codec parameters ?):

 If I remove the -c:s copy it compiles fine but without the subtitles.

 BTW Tried it with Handbrake and it converts fine with subtitles.
