• ffmpeg mp4 video cannot be played in old tv

  24 mai 2020, par Rick Brian

  I've convert many video to mp4 using ffmpeg and playing well on my TV.
  
But ever since I change my laptop to a new one, my conversion failed to load on the TV.

  



  I have tried to download old-stable ffmpeg Windows build, I tried also download a win-32 build, no good.
(I'm using x64 laptop with Windows 10 64-bit, just the same like previous laptop)
  
I also tried to add -pix_fmt yuv420p, still no good.

  



  This is code that I used to convert using ffmpeg :
  
ffmpeg -f concat -i "D:\Convert\LISTCAM.TXT" -c:v libx264 -c:a aac -pix_fmt yuv420p "Apr 2nd.mp4"

  



  I also tried to compare using ffmpeg -i between my playable mp4 file with new not-playable mp4,
  
both are just similar except the encoder header.

  



  Playable mp4 :

  Update :

  



  

  • I did a single-file input instead of a concatenation list.

  


  • I did a codec copy from a playable file, it works, but when I try to re-encode, it does not.
    
ffmpeg -i "Playable-video-file.mp4" -c:v copy -c:a aac "Output.mp4" this works

  


  



  ffmpeg -i "Playable-video-file.mp4" -c:v libx264 -crf 23 -profile:v main -level:v 3.0 -preset:v medium -c:a aac "Output.mp4" and this don't

  



  

  • I did the very same syntax and the same ffmpeg build on a friend's laptop with the same Windows 10 x64 architecture... the output file works fine and playable on my TV...

  


  • Friend's is Intel i5, mine is Intel i7

  


  


• why ffmpeg php conversion 0 bytes empty

  9 avril 2020, par user3080392

  I'm trying to convert a .wav file to .ogg with php and ffmpeg. The ogg file keeps being created as 0 bytes :

  



  <?php
$ffmpeg = "/usr/local/bin/ffmpeg";
shell_exec("$ffmpeg -y -i clip.wav clip.ogg");
?>


  



  I've tried various parameters for the ogg file, but none work. This simple conversion should work, but it doesn't.

  



  Here is the log :

  However streaming individual files works :

  



  ffmpeg -re -stream_loop -1 -i out001.ts -f mpegts -vcodec copy -acodec copy http://localhost:8081/yoursecret


  



  I've also tried but also does not work :

  



  ffmpeg -re -stream_loop -1 -i <(for %%i in (*.ts) do @echo file '%%i') -f mpegts -vcodec copy -acodec copy http://localhost:8081/yoursecret
