[FFmpeg-user] Subtitles when converting .m2ts to .m4v

Sun Jan 27 01:26:09 CET 2013

Hi,

I get the error "Could not write header for output file #0 (incorrect codec parameters ?): Operation not permitted" when converting PGS subtitle streams from a source .m2ts file to an output .m4v file.  Converting to a .mkv works fine for the subtitles, so at least the source file is OK.

Thanks in advance for the help!

Here's the input file:

Input #0, mpegts, from 'myvideo.m2ts':

Here's the command I used:

ffmpeg -i myvideo.m2ts -map 0:0 -map 0:2 -map 0:4 -map 0:5 -c:v copy -c:a libfaac -c:s dvdsub myvideo.m4v

The following error relates to the subtitles, since if I remove the -map 0:4 and -map 0:5 options from the command, the problem goes away:
