Comment (by ramitbhalla): One more problem I've seen (in the same wtv file above). when using the ffmpeg command to copy the subtitle stream it converts the subtitles from dvb_teletext to dvb_subtitle (from text to image if I understand correct). Is that normal? Shouldn' it preserve the teletext stream? e.g. ffmpeg -i ncis.wtv {{{ Duration: 00:31:59.52, start: 1.797444, bitrate: 874 kb/s Stream #0:0[0xe](eng): Audio: ac3, 48000 Hz, 5.1(side), s16, 384 kb/s Stream #0:1[0xf](eng): Audio: ac3, 48000 Hz, stereo, s16, 192 kb/s Stream #0:2[0x10]: Video: mpeg2video (Main), yuv420p, 1920x1080 [SAR 1:1 DAR 16:9], 38810 kb/s, 57.22 fps, 29.97 tbr , 10000k tbn, 59.94 tbc Stream #0:3[0x11]: Subtitle: dvb_teletext Stream #0:4[0x0]: Attachment: mjpeg }}} After stream copying to TS, ffmpeg -i ncis.ts {{{ Stream #0:0[0x100](eng): Audio: ac3 ([129][0][0][0] / 0x0081), 48000 Hz, 5.1(side), s16, 384 kb/s Stream #0:1[0x101](eng): Audio: ac3 ([129][0][0][0] / 0x0081), 48000 Hz, stereo, s16, 192 kb/s Stream #0:2[0x102]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), yuv420p, 1920x1080 [SAR 1:1 DAR 16:9], 38810 k b/s, 29.97 fps, 29.97 tbr, 90k tbn, 59.94 tbc Stream #0:3[0x103](eng): Subtitle: dvb_subtitle ([6][0][0][0] / 0x0006) }}} -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1482#comment:7> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker _______________________________________________ FFmpeg-trac mailing list FFmpeg-trac@avcodec.org http://avcodec.org/mailman/listinfo/ffmpeg-trac
