Based on this post: http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2009-February/060823.html The following command should work: ./ffmpeg -i Starship_Troopers.vob -s 1280x536 -vtag DX50 -vcodec mpeg4 -an -scodec xsub -y test.avi with the sample from http://samples.mplayerhq.hu/MPEG-VOB/ClosedCaptions/Starship_Troopers.vob But I get the same error: > /usr/local/ffmpeg/bin/ffmpeg -i Starship_Troopers.vob -s 1280x536 -vtag DX50 -vcodec mpeg4 -an -scodec xsub -y test.avi FFmpeg version git-svn-r26004, Copyright (c) 2000-2010 the FFmpeg developers built on Dec 14 2010 10:02:50 with gcc 4.3.2 configuration: --prefix=/usr/local/ffmpeg --enable-avfilter --enable-bzlib --enable-gpl --enable-libfaac --enable-libmp3lame --enable-libvorbis --enable-libxvid --enable-nonfree --enable-postproc --enable-pthreads --enable-shared --enable-x11grab --enable-zlib --disable-stripping libavutil 50.34. 0 / 50.34. 0 libavcore 0.16. 0 / 0.16. 0 libavcodec 52.99. 1 / 52.99. 1 libavformat 52.88. 0 / 52.88. 0 libavdevice 52. 2. 2 / 52. 2. 2 libavfilter 1.69. 0 / 1.69. 0 libswscale 0.12. 0 / 0.12. 0 libpostproc 51. 2. 0 / 51. 2. 0 [mpeg @ 0x98924e0] max_analyze_duration reached Seems stream 0 codec frame rate differs from container frame rate: 59.94 (60000/1001) -> 59.94 (60000/1001) Input #0, mpeg, from 'Starship_Troopers.vob': Duration: 00:00:51.28, start: 1986.626100, bitrate: 4620 kb/s Stream #0.0[0x1e0]: Video: mpeg2video, yuv420p, 720x480 [PAR 32:27 DAR 16:9], 9800 kb/s, 23.98 fps, 59.94 tbr, 90k tbn, 59.94 tbc Stream #0.1[0x83]: Audio: ac3, 48000 Hz, stereo, s16, 192 kb/s Stream #0.2[0x82]: Audio: ac3, 48000 Hz, stereo, s16, 192 kb/s Stream #0.3[0x80]: Audio: ac3, 48000 Hz, stereo, s16, 192 kb/s Stream #0.4[0x81]: Audio: ac3, 48000 Hz, 5.1, s16, 384 kb/s Stream #0.5[0x20]: Subtitle: dvdsub Stream #0.6[0x22]: Subtitle: dvdsub [buffer @ 0x98a75e0] w:720 h:480 pixfmt:yuv420p [scale @ 0x989b460] w:720 h:480 fmt:yuv420p -> w:1280 h:536 fmt:yuv420p flags:0xa0000004 Output #0, avi, to 'test.avi': Metadata: ISFT : Lavf52.88.0 Stream #0.0: Video: mpeg4, yuv420p, 1280x536 [PAR 67:90 DAR 16:9], q=2-31, 200 kb/s, 59.94 tbn, 59.94 tbc Stream #0.1Floating point exception ---------- title: Floating exception when transcoding between ASS and XSUB subtitles -> Floating exception from XSUB subtitle encoder ________________________________________________ FFmpeg issue tracker <[email protected]> <https://roundup.ffmpeg.org/issue2424> ________________________________________________
