[FFmpeg-devel] DVB Subtitles Live transcoding

[Liam Carter]

Hiya All.

We are having issues with DVB Subtitles.

Our streams come from MUMUDVB and if played in VLC directly the subtitles
appear as a subtitle stream that can be turned on and off.

When we pass the stream through FFMpeg the subtitles no longer appear.

We have tried using the map feature

-map 0:0 -map 0:1 -map 0:8 -scodec copy

0= video
1= audio
8= dvb subtitles.

Stream #0:0: Video: mpeg2video ([2][0][0][0] / 0x0002), yuv420p, 720x576
[SAR 64:45 DAR 16:9], q=2-31, max. 15000 kb/s, 25 fps, 25 tbr, 90k tbn, 90k
tbc
    Stream #0:1(eng): Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, stereo,
224 kb/s
    Stream #0:2(eng): Subtitle: dvb_subtitle ([6][0][0][0] / 0x0006)
Stream mapping:
  Stream #0:0 -> #0:0 (copy)
  Stream #0:1 -> #0:1 (copy)
  Stream #0:8 -> #0:2 (copy)

When we open in VLC the subtitle option is available yet the subtitle
doesn't show.

It is if the subtitles are not being passed correctly as a stream.

Not sure how to proceed as we have been at this for ages and exhausted all
of the internets resources lol (well it feels like that).

Any help appreciated

Cheers
