• FFmpeg .jpg images to .mp4 incompatible with Windows Media Player

  8 janvier 2020, par willspill

  I have a series of 10 images with which I am trying to form an animation. I have used the following code below in the command line :

  ffmpeg -f image2 -i plot-%03d.jpg -r 5 -pix_fmt yuv420p -vcodec mpeg4 output.mp4

  This creates a .mp4 file with a seemingly valid file size, however, when trying to open with Windows Media Player gives the following error :

  Windows Media Player cannot play the file. The Player might not support the file type or might not support the codec that was used to compress the file.

  I have tried many solutions from previous threads but have found no solution. I have checked that my version of windows media player is compatible with mp4, avi, wmv etc. and have tried all of these outputs also. Any ideas of the issue ?

  The full code :

• Debian php ffmpeg error "Could not get frame filename number 2 from pattern"

  22 août 2021, par Sam

  My code below works fine in on my osx laptop

  


  $sec = 1;
$ffmpeg = \FFMpeg\FFMpeg::create([
   'ffmpeg.binaries'  => exec('which ffmpeg'),
   'ffprobe.binaries' => exec('which ffprobe')
]);

$video = $ffmpeg->open($file);
$frame = $video->frame(TimeCode::fromSeconds($sec));
if(!file_exists($newFilePath)) {
      $frame->save($newFilePath);
      $this->output->writeln('make: ' . $newFilePath);
}


  


  but on debian I get error Could not get frame filename number 2 from pattern

  


  here is the error description from ffmpeg website

  


  


  This usually occurs because the output name is incorrect or some option was omitted.
If outputting a single image you need to include -frames:v 1.
If outputting a series of images you need to use the proper naming pattern as described in the image muxer documentation. For example, output_%03d.png will make a series named output_001.png, output_002.png, output_003.png, etc.
If outputting a single image that is continuously overwritten with new images, add -update 1.

  


  


  My filename looks fine to me

  


  here is the detailed error :

• Cannot suppress ffmpeg output from ruby

  3 avril 2014, par Danny

  I have ruby on rails app that allows users to upload videos. When a video is added, I have a before_save filter that uses ffmpeg to generate a series of thumbnails. The problem is that ffmpeg is producing tons of console output when I'm saving a video item in the rails console, and when I run my tests.

  My environment :

  • Host Machine : OS X 10.9.2
  • Vagrant Box : Ubuntu 10.04.4
  • ffmpeg version : SVN-r0.5.9-4:0.5.9-0ubuntu0.10.04.3
  • ruby version : 1.9.3-p194

  Command I'm running :

  `ffmpeg -v 0 -ss #{timestamp} -i #{video_file.path} -y -f image2 -vcodec mjpeg -vframes 1 -s 640*360 #{thumbnail_path}/thumbnail#{i}.jpg`

  This version of ffmpeg on my VM doesn't seem to care about the "-v 0" option. I've also tried "-loglevel quiet" which causes ffmpeg to error, indicating that the option isn't recognized (both loglevel and v work on my host machine's ffmpeg).

  Tried using both exec() and system(), which both caused execution to hang. Tried to redirecting output to a file by doing :

  `ffmpeg -v 0 -ss #{timestamp} -i #{video_file.path} -y -f image2 -vcodec mjpeg -vframes 1 -s 640*360 #{thumbnail_path}/thumbnail#{i}.jpg > #{thumbnail_path}/output.txt`

  Still see output. Next I tried :

  `ffmpeg -v 0 -ss #{timestamp} -i #{video_file.path} -y -f image2 -vcodec mjpeg -vframes 1 -s 640*360 #{thumbnail_path}/thumbnail#{i}.jpg &> dev/null`

  Still seeing output ! Finally I tried :

  $stdout.reopen("#{thumbnail_path}/output.txt", "w")
  
  $stderr.reopen("#{thumbnail_path}/error.txt", "w")
  
  `ffmpeg -v 0 -ss #{timestamp} -i #{video_file.path} -y -f image2 -vcodec mjpeg -vframes 1 -s 640*360 #{thumbnail_path}/thumbnail#{i}.jpg`
  
  $stdout = STDOUT
  
  $stderr = STDERR

  Holy cow, that worked ! Well, sort of. No more verbose output when running tests, BUT somehow anytime this runs I get kicked out of the rails console.

  Does anyone have a more elegant solution ?
