• Remuxing MKV to MP4 fails when using -map 0 but works fine when Remuxing MP4 to MKV

  20 septembre 2020, par AppetiteForDestruction

  I 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 user3058763

  How 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

• input.mod : could not find codec parameters [closed]

  8 février 2021, par JustBaibe

  I am trying to covert a .MOD file to .MP4 or .M4V using FFmpeg but getting an error. I have tried adding codec from X-Lite because thought might be missing something that allows reading .MOD files but still getting the error.

  


  This is the ffmpeg command I used :

  


  ffmpeg -f mpeg -i "input.mod" -vcodec copy -acodec mp2 -ab 192k "output.mp4"


  


  and this is what I received :

  


  ffmpeg -f mpeg -i "input.mod" -vcodec copy -acodec mp2 -ab 192k "output.mp4"

input.mod: could not find codec parameters


  


  I've tried just pulling up the file using ffprobe and got :

  


  "input.mod: could not find codec parameters". 


  


  When I've tried to open the file using X-Lite (MPC-HC 64), it says "Not rendered".

  


  Trying to at least play the file. Do I need to covert it to something else instead, like Webm ?
