This means, in order to prevent them from overflowing, please change them to {{{%9s %63s}}, because of the trailing nullterminating string ('\0') at the end.

#1778(FFmpeg:new): EIA-608 / EIA-708 Closed Captions disappear when transcoding/reencoding

#1778: EIA-608 / EIA-708 Closed Captions disappear when transcoding/reencoding -------------------------------------+------------------------------------- Reporter: mikecheat04 | Type: defect Status: new | Priority: normal Component: FFmpeg | Version: 1.0 Keywords: cc, closed | Blocked By: caption, subtitle, teletext, eia, | Reproduced by developer: 0 608, 708 | Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: When transoding/reencoding video ffmepg loses the CC data that was embedded within the actual video stream itself. This type of CC is referred to as EIA-608/EIA-708 and is muxed to the video stream following guidelines in SCTE 128 from my research. If you use '-c:v copy' the CC remains intact. I'm capturing live video from the gige port of a Motorola DSR-6100 IRD that is putting out UDP multicast TS. This PDF give more details regarding how this method of CC works: http://www.evertz.com/resources/eia_608_708_cc.pdf Here are the files produced from the below command. They are larger than the 10MB requested so I've hosted them on my site, here are the direct links. http://mikecheat.com/disjrhd.ts - Original(18.2MB) http://mikecheat.com/disjrsd.ts - Reencoded(8.9MB) There is another open source project that seems to have figured out how to pull this CC data from video. They have the source code on their website, I've included the link. http://zapping.sourceforge.net/ZVBI/index.html How to reproduce: root@hdmux:/home/mike# ffmpeg -i 'udp://239.1.1.3:6100?fifo_size=9000000' -map 0:p:1:0 -c:v mpeg2video -s 704x480 -r ntsc -b:v 3000k -map 0:p:1:1 -c:a mp3 -ac 2 -ar 48000 -b:a 128k -f mpegts disjrsd.ts -map 0:p:1:0 -c:v copy -map 0:p:1:1 -c:a copy -f mpegts disjrhd.ts ffmpeg version 1.0 Copyright (c) 2000-2012 the FFmpeg developers built on Sep 28 2012 14:24:44 with gcc 4.4.5 (Debian 4.4.5-8) configuration: --enable-gpl --enable-nonfree --enable-shared --enable- runtime-cpudetect --enable-libmp3lame --enable-libx264 libavutil 51. 73.101 / 51. 73.101 libavcodec 54. 59.100 / 54. 59.100 libavformat 54. 29.104 / 54. 29.104 libavdevice 54. 2.101 / 54. 2.101 libavfilter 3. 17.100 / 3. 17.100 libswscale 2. 1.101 / 2. 1.101 libswresample 0. 15.100 / 0. 15.100 libpostproc 52. 0.100 / 52. 0.100 [mpegts @ 0x2169240] Unable to seek back to the start [h264 @ 0x2193a80] non-existing PPS referenced [h264 @ 0x2193a80] non-existing PPS 0 referenced [h264 @ 0x2193a80] decode_slice_header error [h264 @ 0x2193a80] no frame!
