Remuxing MKV to MP4 fails when using -map 0 but works fine when Remuxing MP4 to MKV
20 septembre 2020, par AppetiteForDestructionI have an MKV file that contains 5 streams...


0 : video

1 : audio

2 : audio

3 : text

4 : menu

I was able to remux the MKV into an MP4 using this command...


> ffmpeg.exe -i input.mp4 -map 0 -c copy -c:s mov_text output.mkv



The resulting output MP4 contains all the streams from the original MKV.


But if I try to remux the output MP4 into an MKV using the same command, but with a different codec for the subtitles (srt) and different file extension (mkv), I get an error. However, if I omit "-map 0" from the command, it works but only ONE of the audio streams get copied to the output MKV file.


====================

 Steps to Reproduce

====================

These two commands work, however, the output MKV only contains ONE of the TWO audio streams...


> ffmpeg.exe -i input.mp4 -c copy -c:s srt output.mkv
> ffmpeg.exe -i input.mp4 -c:v copy -c:a copy -c:s srt output.mkv



When I try to use either of the two commands below using "-map 0" just like I did when I remuxed the original MKV into an MP4, the commands fail and both result in the "Full Output" shown at the bottom...


> ffmpeg.exe -i input.mp4 -map 0 -c copy -c:s srt output.mkv
> ffmpeg.exe -i input.mp4 -map 0 -c:v copy -c:a copy -c:s srt output.mkv



Output Error


Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument



So why would using "-map 0" cause it to fail when I used the exact same command to remux the original MKV into an MP4 ? And why does omitting "-map 0" allow it to work, but obviously doesn't copy both audio streams ? Seems like a BUG to me because why does practically the exact same command work for going from MKV to MP4, but not from MP4 to MKV ?

How to put video on top of overlay using FFmpeg ?
23 juillet 2020, par user3058763How to merge a video and an image (or a black overlay) to get the video on top ?


Input video is already prepared for this (its maximum width/height is 1920x1080) and needs to stay at original size.


This is how it should look like :



orange is an overlay/image (1920x1080px),
pink is a video on top of it (and centered)


The best shot so far I've got :


ffplay -vf "pad=1920:1080:(ow-iw)/2:(oh-ih)/2" input.mp4



this most likely works, but I can't save the image to check.


But this does nothing to the video :


ffmpeg -i input.mp4 -vf "pad=1920:1080:(ow-iw)/2:(oh-ih)/2" output.mp4



Bonus points if you know how to put an image instead of black overlay.
Thank you !


Full logs of the command (output video remains the same resolution as input) :


ffmpeg -i input.mp4 -vf "pad=1920:1080:(ow-iw)/2:(oh-ih)/2" output.mp4
