[Libav-user] Trying to create a DVDSUB (.sub) according to Specification

[Wagner Patriota]

I think that the correct name of the file I wanna create is MPEG-PS (RLE).

My mediainfo says:

Format: MPEG-PS

ID: 189 (0xBD)-32 (0x20)****

Format: RLE****

Format/Info: Run-length encoding****

Muxing mode: DVD-Video

Duration: 1mn 45s

FFmpeg is supposed to interpret 2, 4 or 8 bit version of the bitmap
cotained on this file... I have a sample attached. When I use it with
FFmpeg it does not work perfectly on TV. It goes fine on VLC but on TV it
doesn't work. [muxing with MPEG2-TS video]

ffmpeg -i input.ts *-i a.sub* -vcodec copy -acodec copy *-scodec
dvbsub*output.ts
