[FFmpeg-user] dvbsub problem

Hi Carl Eugen,

No problem.

/usr/bin/ffmpeg -i mux1.flight93.ts  -codec copy -map 0:3 -map 0:7 -map 
0:11 -f mpegts -y out.ts 2>err.out

and the console output is attached.

The problem is that the output file has a dvbsub stream but the stream 
is empty. There are no subtitles visible when you play it in vlc.
The same stream in the original file is not empty - it has 
danish-language subtitles.

If I try to dump only the dvbsub stream with ffmpeg:

/usr/bin/ffmpeg -i mux1.flight93.ts -an -vn -scodec copy  -map 0:11  -f 
mpegts   -y out.ts
I get the following (truncated this time, but you can have the full 
output if you like):

Output #0, mpegts, to 'out.ts':
     encoder         : Lavf53.24.2
     Stream #0:0(dan): Subtitle: dvb_subtitle ([6][0][0][0] / 0x0006)
Stream mapping:
   Stream #0:11 -> #0:0 (copy)

Note that the output file is not zero size.
