#1277: Subtitle conversion fails -------------------------------------+------------------------------------- Reporter: bakhshian | Type: defect Status: new | Priority: important Component: FFmpeg | Version: 0.10.2 Keywords: pgssub -> | Blocked By: dvdsub | Reproduced by developer: 0 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- I need to convert the format of the subtitle stream of a movie so my device can play it. Here is the list of all existing streams :
Stream #0:0(eng): Video: h264 (High), yuv420p, 1920x816 [SAR 1:1 DAR 40:17], 23.98 fps, 23.98 tbr, 1k tbn, 47.95 tbc (default) Stream #0:1(eng): Audio: dts (DTS), 48000 Hz, 5.1(side), s16, 1536 kb/s (default) Metadata: title : 3/2+1 Stream #0:2(eng): Subtitle: hdmv_pgs_subtitle (default) Stream #0:3(ger): Subtitle: hdmv_pgs_subtitle Stream #0:4(ger): Subtitle: hdmv_pgs_subtitle Stream #0:5(ger): Subtitle: hdmv_pgs_subtitle Stream #0:6(ger): Subtitle: hdmv_pgs_subtitle I want to keep only the English subtitle and convert it too. The available codecs are : > ffmpeg -codecs | grep sub DES ass Advanced SubStation Alpha subtitle DES dvbsub DVB subtitles DES dvdsub DVD subtitles D S pgssub HDMV Presentation Graphic Stream subtitles DES srt SubRip subtitle DES xsub DivX subtitles (XSUB) I choose dvdsub as the new format and try to run ffmpeg command with the following arguments : >ffmpeg -i in.mkv -scodec dvdsub -vcodec copy -acodec copy out.mkv It starts running, but after a while ( I think when it reaches the first frame with subtitle ) crashes. Here you can see the messages : Stream mapping: Stream #0:0 -> #0:0 (copy) Stream #0:1 -> #0:1 (copy) Stream #0:2 -> #0:2 (pgssub -> dvdsub) Press [q] to stop, [?] for help Subtitle encoding failed1.0 size= 182919kB time=00:00:00.00 bitrate= 0.0kbits/s The interesting point is that ffplay and mplayer both can play the input file and they show the subtitle properly.
