FFmpeg commands: Doesn't show the merge command.

[piezanno]

Hi, minor issue, but I noticed when you cut and merge a file, the ffmpeg commands show up for the cut, but not for the merge. Thanks

By the way, fantastic program

Hi. What do you need the merge command for? I think the reason why I don't log it is because it will not be very useful, because it looks like this:

 ffmpeg -hide_banner -f concat -safe 0 -protocol_whitelist 'file,pipe' -i - -c copy -map 0 -movflags '+faststart' -ignore_unknown -strict experimental -f mp4 -y 'cut-file-merged-1641026628937.mp4'

Thank you Mikael for the command. I wanted to see it because I’m having a problem with subtitles on a couple files. I wanted to see if I could extract some segments and modify the merge command manually. I’ll check it out and let you know what I find in a couple days. Karl P.

losslesscut could log the concat list along with the command but I'm not sure if it's something a lot of people would need.

Yes, I agree the command would not help. So here’s why I was asking. 1. I record a lot of shows using Playon desktop - they recently began passing subtitles and saving the subs stream in the .mp4 file. 2. I noticed on some of the newer recordings, once I modified them by removing advertising chapters in losslesscut, the audio was really out of sync with the video in the new concatenated file. However, the subtitles and video were in sync while the audio was out of sync. 3. So I investigated and finally found using “ffprobe filename” that all the input files causing problems had the following warning in the ffprobe output: Unsupported codec with id 100359 for input stream xx. 4. I originally thought this error was in the subtitle streams, but found out it’s actually in the titles in the metadata. And if I didn’t copy any metadata over in the concat command (using ffmpeg), the resultant file was ok. 5. I found an additional command that let’s me copy the metadata over and ignore the chapter titles. That command is. ffmpeg -loglevel error -hide_banner -nostats -f concat -safe 0 -i to.txt -c copy -c:v copy -dn -map_metadata:c -1 -map 0 -c:s mov_text testOutMerged.mp4 Thanks for your help Karl P.

now implemented:
will log like this:

echo -e "file 'file:timecode-smartcut-segment-encode-0.mp4'\nfile 'file:timecode-smartcut-segment-copy-0.mp4'" | ffmpeg -hide_banner -f concat -safe 0 -protocol_whitelist 'file,pipe' -i - -i 'timecode-smartcut-segment-copy-0.mp4' -map '0:0' '-c:0' copy '-disposition:0' default -map '0:1' '-c:1' copy '-disposition:1' default -map '0:2' '-c:2' copy -map_metadata 1 -movflags '+faststart' -default_mode infer_no_subs -ignore_unknown -video_track_timescale 24000 -f mp4 -y 'out.mp4'
