Re: [FFmpeg-user] How to concat two videos with same size but different source?

as it told you at the begin of this thread: you can't concat video 
formats like H264 as it where wave audiofiles


that begins with https://www.web3.lu/indexing-moov-atom-in-h264-video-files/

and that part is pretty sure the reason most players saysing "i am done" 
after the first



If it is then I need probably to translate each snippet to something entirely
different like ts before concatenate with re-encode using libx264 and aac?

And that would increase the needed processing time a lot


but if you are it plays everywhere

A good start would be the complete uncut command line output which might
have some extra info, a sample could be useful, and perhaps info about the
raw file. Is it definitely 10bit gray? Which video player have you used to
play it back, have you tried another like mpv?

Best,

Kieran

I meant which video player, like VLC etc. MPV is another player, not a
command line flag.
Anyhow  I didn't even know that x264 supported gray, but looks like vlc
supports it. Can you try this:
ffmpeg -pixel_format
gray10be -s 1600x1300 -r 30 -i CapturedImage-%03d.raw -c:v libx264 -pic_fmt
yuv420p -crf 18
raw_video.mp4

Perhaps switching to yuv420p will help with h264 playback compatibility?

Best,

K
