• How do I formate spaces in terminal for FFMPEG metadata

  22 juillet 2020, par pbendevis

  I can't get FFMPEG to accept any spaces when I try to assign it to the metadata. Below is the command I am using in Terminal on MacOS. It gives me an error : [NULL @ 0x7fce76026600] Unable to find a suitable output format for 'World' World: Invalid argument

  


  ffmpeg -hide_banner \

  I have tried 'title="Trolls World Tour"' title=Trolls" "World" "Tour to no luck.

  


  Using title="Trolls\ World\ Tour" works but then the title includes the backslashes.

  


  Any thoughts ?

  


• How to concat videos with FFMPEG without a black frame in the middle

  21 juillet 2020, par david k

  I need to join two videos together programmatically, and FFMPEG seems to be working perfectly except it leaves a single black frame between the two joined videos.

  


  Based on this post, I'm guessing it's because the video and audio streams aren't exactly the same length (not sure why). Since I'm seeing a black flash, I'm guessing that the audio is slightly longer than the video, but I can't figure out how to remedy that. I'm fine losing a tiny piece of the audio at the end of the file.

  


  Can anyone help me "trim" the end of my audio stream so that it matches my video stream ? I need to be able to do this for many files, so I can't just hard-code a value into my command.

  


  I've attempted both of the methods that FFMPEG provides to concat, and both of them have this issue. I'd be fine with either approach, if I can get rid of the black frame.

  


  Transcode :

  


  ffmpeg -i video1.mp4 -i video2.mp4 -filter_complex \
  "[0:v][0:a][1:v][1:a] concat=n=2:v=1:a=1 [outv] [outa]" \
  -map "[outv]" -map "[outa]" output.mp4


  


  Re-wrap :

  


  ffmpeg -f concat -i files.txt -c copy output.mp4


  


  Here is the output of ffmpeg -i video1.mp4 -i video2.mp4 :

• 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 ?
