• Clips from a Live Video

  12 mai 2022, par Jorge Borreguero Sanmartin

  I am doing a program in Python that gets clips from a live video. To do so, with opencv I get the currrrent_frame_position and with the fps I get the start and final time to run this command :

  


  ffmpeg -i live_video.ts -ss 00:01:30 -to 00:02:00 -c:v copy output.ts

  


  To improve, I want to start dumping the live_video on the new file once I know the starting time, and finish once I get the final time. My intention is to make this process faster and get the result file sooner. It is not necessary to use ffmpeg but it is the tool that I have been using. How can I do this ?

• Thumbnail generation in Laravel with FFmpeg

  28 mai 2023, par hehehhehehe

  Using FFmpeg video upload is successful in the database, but the file is not found in the storage directory. I want to make a thumbnail of the video that has just been uploaded using FFmpeg in Laravel. When viewed in the database it has been uploaded, but when viewed in the Laravel storage directory the file does not exist. What is the solution ?

  


  $store = new Post();
$files = $request->file('file');
$ext = $files->getClientOriginalExtension();
if ($ext == 'mp4' || $ext == 'mkv' || $ext == 'webm') {
   $ext = $request->file('file')->extension();
   $final = 'video' . time() . '.' . $ext;
   $request->file('file')->move(storage_path('app/public/uploads/video/'), $final);
   $store->file = $final;

   // For Thumbnail
   $thumbnailName = 'thumbnail' . time() . '.jpg';
   $thumbnailPath = storage_path('app/public/uploads/video/thumbnails/') . $thumbnailName;

   $ffmpegCommand = "ffmpeg -i " . storage_path('app/public/uploads/video/') . $final . " -ss   00:00:01.00 -vframes 1 " . $thumbnailPath;
   exec($ffmpegCommand);

   $store->thumbnail = $thumbnailName;
}


  


  I've looked and tried coding based on the latest documentation, but it still can't run.
