Hi, I have a *.ts file and if I play it on VLC I can see 4 tracks for closed caption and if I select track 1 I can see the closed captions on the screen. I'm trying to extract those to an srt file but I didn't find a way.
I tried the following command: ffmpeg -f lavfi -i "movie=output.ts[out+subcc]" -map s output.srt > > ffmpeg version 3.2.2 Copyright (c) 2000-2016 the FFmpeg developers > built with gcc 5.4.0 (GCC) > configuration: --enable-gpl --enable-libx264 --prefix=/usr > libavutil 55. 34.100 / 55. 34.100 > libavcodec 57. 64.101 / 57. 64.101 > libavformat 57. 56.100 / 57. 56.100 > libavdevice 57. 1.100 / 57. 1.100 > libavfilter 6. 65.100 / 6. 65.100 > libswscale 4. 2.100 / 4. 2.100 > libswresample 2. 3.100 / 2. 3.100 > libpostproc 54. 1.100 / 54. 1.100 > Input #0, lavfi, from 'movie=output.ts[out+subcc]': > Duration: N/A, start: 1.767033, bitrate: N/A > Stream #0:0: Video: rawvideo (I420 / 0x30323449), yuv420p, 720x480 > [SAR 1:1 DAR 3:2], 29.97 fps, 29.97 tbr, 90k tbn, 90k tbc > Stream #0:1: Subtitle: eia_608 > Output #0, srt, to 'output.srt': > Metadata: > encoder : Lavf57.56.100 > Stream #0:0: Subtitle: subrip (srt) > Metadata: > encoder : Lavc57.64.101 srt > Stream mapping: > Stream #0:1 -> #0:0 (eia_608 (cc_dec) -> subrip (srt)) > Press [q] to stop, [?] for help > [mpeg2video @ 0x27d88c0] ac-tex damaged at 3 6peed= 0x > [mpeg2video @ 0x27d88c0] Warning MVs not available > [mpeg2video @ 0x27d88c0] concealing 1080 DC, 1080 AC, 1080 MV errors in P > frame > size= 0kB time=00:00:00.00 bitrate=N/A speed= 0x > video:0kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB > muxing overhead: unknown > Output file is empty, nothing was encoded (check -ss / -t / -frames > parameters if used) > ffmpeg says there is no closed caption (empty file) but it has, I can play it with VLC.
