• ffmpeg - convert MP4 to Panasonic Lumix playable MJPEG [closed]

  21 août 2024, par Maro Natts

  I'm new to ffmpeg and ffprobe, I started using it to convert videos to show on 3DS and DSi for an art project.

  


  Now I want to show my own videos on a Panasonic LUMIX digicam (DMC-FT2)(JPN), but have had trouble getting the device to play the video.

  


  The digi takes videos in AVCHD Lite and Motion JPEG.

  


  I've tried online converting mp4 to the respective formats + changing file name, but the device only recognises that it's there — refuses to/can't play it.

  


  I also tried using this code to convert to MJPEG :
ffmpeg -i input.mp4 -c:v mjpeg -q:v 2 -an output.mjpeg

  


  But no luck ! Changed the filename to match the others, the camera recognised the file is there, but can't play it.

  


  So I used this code to get the information of a MJPEG video taken on the digi :
/opt/ffmpeg/ffprobe file.mp4 -show_streams  -select_streams v  -print_format json

  


  and got the following, is it possible to convert my own video (mp4) to these settings ? So that it can play on the device ? If so how ?

  


  Thanks !

• Facing issues with adding text over a video as watermark using ffmpeg in Laravel

  18 septembre 2024, par Kelash

  I am facing issues with adding text over a video as a watermark using pbmedia/laravel-ffmpeg.

  


  Where am I going wrong ?

  


  Code :

  


  $format = new X264();
$format->setAudioCodec('aac');
$format->setVideoCodec('libx264');
$format->setKiloBitrate(0);

$localPath = '/' . $this->video->id . '.mp4';

$ffmpeg = FFMpeg::fromDisk("public")
          ->open($localPath)
          ->addFilter(function ($filters) {
            $filters->custom("drawtext=fontfile=S:/Freelancer/version58trials/version58trials/public/webfonts/arial.TTF:text='Stack Overflow':fontcolor=white:fontsize=24");
          })
          ->export()
          ->toDisk('public')
          ->inFormat($format)
          ->save("watermark_video_added.mp4");


  


  And this is error I am getting :

  What I tried, is manipulating that filter function but I couldn't make it.

  


  For your knowledge,the video paths and font path is correct the only issue is with ffmpeg adding watermark text logic.
