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