Re: [FFmpeg-user] Closed Captions for zone 1 DVD
Hello Carl Eugen, Please note that this case is now closed for me. I found this workaround : ffmpeg -t 180 -i INPUT.mp4 -c copy TMP.mp4 ffmpeg -f lavfi -i "movie=TMP.mp4[out0+subcc]" -map s OUTPUT.srt -v warning When there are no Closed Captions within the first 3 minutes of the video stream, ffmpeg displays a warning : Output file is empty ... The drawback is that this is a very slow procedure. Actually, my initial objective was to remove the Closed Captions from all my movies. I finally found how to do it, in a fast and efficient way, even if the video stream does NOT contain CC : ffmpeg -i INPUT.mp4 -c copy -bsf:v filter_units=remove_types=6 OUTPUT.mp4 Thank you for your help Best Rgds Pascal Message du 08/05/20 22:54 De : "Carl Eugen Hoyos" A : "FFmpeg user questions" Copie à : Objet : Re: [FFmpeg-user] Closed Captions for zone 1 DVD > Am 08.05.2020 um 22:28 schrieb PPRJ01 : > > > Please find attached a short sample file named "2005.mp4".

Re: [FFmpeg-user] Closed Captions for zone 1 DVD
Thank you Carl Eugen, I tried adding large values with options "-analyzeduration" and "probesize" but this does NOT work for Closed Captions even if it works properly for regular subtitle streams. Please understand that I am not a beginner. I have a 45 years background in IT support for several companies of more than 100,000 employees all over the world. Have in mind that many people are not developpers and need simple answers to simple questions. Again : is there any special codification of Closed Caption for US DVDs ?

[FFmpeg-user] Closed Captions for zone 1 DVD
Hi All, I don't understand why neither ffmpeg nor ffprobe detect presence of closed captions within MP4/H.264 in some video streams when VLC does. Let me explain this... In the past 20 years, I have been working in several countries over the world and I bought official DVDs. Not duplicates ;-) I ripped them first to VOB and recently converted them to MP4/H.264 with ffmpeg without using the "-a53cc" option. Reminder : when running ffmpeg and ffprobe, a few lines are written first to stderr. The words "Closed Captions", when present, indicate that the video stream contains closed captions. ==> The point is that ffmpeg/ffprobe do not show closed captions existence for MP4/H.264 files that come from ZONE 1 DVDs but VLC does and displays them. ==> Conversely, for zone 2 DVD, ffmpeg/ffprobe work properly. ==> Do you know why this happens ??? I am currently using a Windows 10 version of ffmpeg/ffprobe. Please see the details below with a DVD, bought in zone 1, that contains closed captions.
