I found out that if I added EITHER -c:s copy (s indicates subtitles) OR -c:d copy (d indicates data), then it worked and when I ran mediainfo on the converted file, I now saw this: Text #1 ID : 257 (0x101)-CC1 Menu ID : 1 (0x1) Format : EIA-608 Muxing mode : SCTE 128 / DTVCC Transport Muxing mode, more info : Muxed in Video #1 Duration : 1h 4mn Bit rate mode : Constant Stream size : 0.00 Byte (0%) Text #2 ID : 257 (0x101)-CC3 Menu ID : 1 (0x1) Format : EIA-608 Muxing mode : SCTE 128 / DTVCC Transport Muxing mode, more info : Muxed in Video #1 Duration : 1h 4mn Bit rate mode : Constant Stream size : 0.00 Byte (0%) Text #3 ID : 257 (0x101)-1 Menu ID : 1 (0x1) Format : EIA-708 Muxing mode : SCTE 128 / DTVCC Transport Muxing mode, more info : Muxed in Video #1 Duration : 1h 4mn Bit rate mode : Constant Stream size : 0.00 Byte (0%) Text #4 ID : 257 (0x101)-3 Menu ID : 1 (0x1) Format : EIA-708 Muxing mode : SCTE 128 / DTVCC Transport Muxing mode, more info : Muxed in Video #1 Duration : 1h 4mn Bit rate mode : Constant Stream size : 0.00 Byte (0%) Didn't matter whether I used -c:s copy or -c:d copy, as long as I added one or the other the closed captions were there and I could see them in VLC by selecting s "Subtitles Track" from the Video menu. To me using -c:s makes more intuitive sense, but either way it works. So, thank you for jogging my thought process on this. By the way, I am not saying this will work for over-the-air broadcasts, or even for all satellite feeds, but it works with this one. Nor am I saying this will work when played back using something other than VLC (for example I doubt it would work with XBMC, because they currently don't seem to support subtitles that are not in a separate text file). My final conversion command is this: ffmpeg -loglevel quiet -i "original.ts" -c:v copy -filter_complex '[0:1][0:2][0:3]amerge=inputs=3,pan=5.1|FL=c0|FR=c1|FC=c2|LFE=c3|BL=c4|BR=c5' -c:a ac3 -c:s copy "converted.ts" _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
