  ffplay : use lock manager callback to make libavcodec thread-safe

• The Mystery of the No such file or directory exception

  22 avril 2022, par JohnWick

  No idea what's going on here. Set a breakpoint after the for of loop in the following function. temp/concat.txt exists but the following exception is thrown :

  


  


  Uncaught Error Error : ffmpeg exited with code 1 : temp/concat.txt : No
such file or directory

  


  


  Outputting stderr gives a bit more info :

  


  


  [concat @ 000001e2e30124c0] Impossible to open
'temp/concat.txt#voiceover #funny #fall #lol.mp4' index.js:19
temp/concat.txt : No such file or directory

  


  


  And here is the contents of concat.txt, standard ffmpeg concat demuxer format :

  The function throwing the exception.
