• 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 :

• ffmpeg Output file #0 does not contain any stream when rtsp to png

  10 avril 2022, par Alan Sereb

  I want to take 1 frame from a video and put it to png as a thumbnail and refresh it once in a while, so I run :

  


  ffmpeg -y -i 'rtsp://192.168.2.123' -s 240x135 -vf fps=1 %d.jpg


  


  I get the output :

• FFMPEG, H264 Encoding : If frame size exceeds level limit, does it lead to video encoding failed ?

  4 février 2021, par Nafia Mahjabin

  I want to reencode an mp4 file with h264 encoding.
Run the following command :

  


  


  ffmpeg -i input.mp4 -f mp4 -vcodec h264 -profile:v baseline -level 3.0 -pix_fmt yuv420p -color_range 2 -vf scale=1080:1920 -acodec aac -async 1 output.mp4

  


  


  Process fails saying Video encoding failed.

  I tried to figure out the reason for fail. I'm guessing from error message from the line frame MB size (68x120) > level limit (1620), frame size exceeds h264 level limits may be the issue.

  


  Is it the issue ? if it is, what's the solution for this ? if it's not, what went wrong ?

  


  Can somebody help please ? Thank you !
