• Problem of video duration with a mp4 file

  7 avril 2023, par user1018697

  I have a video file with a duration of 1:24.
I tryed to edit the file with adobe premier 2023 and the duration of file read is 1:14...
Framerate of the video is 24 i/s, i tryed to change to 30 i/s with ffmpeg but the problem persists.

  


  I share the file here :
https://drive.google.com/file/d/1A2DxqJL7whGRrRraeCuyaJ46mAra1n81/view?usp=share_link

  


  If you try to edit the file on the adobe public website, you can reproduce it :
https://express.adobe.com/fr-FR/tools/merge-videos

  


  Can anyone helps me ?

  


• ffmpeg errors when playing a playlist - Non monotonous DTS

  20 novembre 2023, par Evilmachine

  i have a strange bug in ffmpeg. I am using ffmpeg to stream Twitch VODs and CLIPs to a 24/7 twitch channel. If i stream the files one by one its working. If i am streaming a playlist containing vods and clips i get this error when the shorter clips are playing :

  


  [flv @ 0x555677050c60] Non-monotonous DTS in output stream 0:0; previous: 56867, current: 31846; changing to 56867. This may result in incorrect timestamps in the output file.

  


  and the video stops. Once the playlist has a longer vod again it is working.

  


  here is my code that i use to stream :

  


  while [ 1 -eq 1 ]
do
ffmpeg  -fflags +igndts -re -f concat -safe 0 -i playlist.txt -codec copy -flvflags no_duration_filesize -f flv rtmp://XXXXXXXXX
done


  


  If i look into ffprobe the files seems both to be normal :

  


  VODs

• How to resolve Electron ffmpeg error opening input file ?

  26 août 2023, par 3V1LXD

  I have an Electron app with ffmpeg.exe inside the project's bin folder. When i try to use ffmpeg to make a new video I get an error reading the input file.

  


  FFmpeg error: [in#0 @ 000002667f2ab9c0] Error opening input: No such file or directory

Error opening input file C:/Users/xxxx/Videos/Powder/2023.08.19%2017.30.37_Apex_Legends/Powder_2023.08.19%2021.00.48.mp4


  


  const ffmpeg = spawn(ffmpegPath, [
  '-i', videoFile,
  '-filter_complex', filterComplex,
  '-map', '[out]',
  '-c:v', 'libx264',
  '-crf', '18',
  '-preset', 'veryfast',
  '-y',
  path.join(outputDir, outputName)
]);

ffmpeg.stdout.on('data', (data) => {
  console.log(`FFmpeg output: ${data}`);
});

ffmpeg.stderr.on('data', (data) => {
  console.error(`FFmpeg error: ${data}`);
});

ffmpeg.on('close', (code) => {
  console.log(`FFmpeg process exited with code ${code}`);
  event.reply('ffmpeg-export-done'); // Notify the renderer process
});


  


  How can i resolve this path issue ?
