• How to fix error "Encoding Failed" using FFMPEG ?

  17 août 2021, par Irshad Khan

  I am using FFMPEG for converting mp4 to m3u8 format on an Ubuntu local machine. But I am facing an error Encoding Failed.

  


  My controller code is :

  


  FFMpeg::open(public_path()."/uploads/".$filename)
    ->exportForHLS()
    ->addFormat($lowBitrate)
    ->addFormat($midBitrate)
    ->addFormat($highBitrate)
    ->toDisk(env('APP_ENV'))
    ->save(public_path().'/converted/adaptive_steve.m3u8');


  


  The error is :

  


  

  


  Config file is

  


  

  


  How can I solve this ? Thanks

  


• Gstreamer, x264enc "Redistribute latency..." error

  20 août 2021, par Jason

  I'm trying to setup a video pipeline with very limited bandwidth. I was able to do it with two raspberry pis using the below lines. The first is for the camera pi and the second is to watch stream :

  


  gst-launch-1.0 rpicamsrc preview=false !  'video/x-h264, width=800, height=600, framerate=30/1' ! h264parse ! rtph264pay config-interval=1 pt=96 ! gdppay ! udpsink host=YOUR_PC_IP port=5000
gst-launch-1.0 udpsrc port=5000 ! gdpdepay ! rtph264depay ! h264parse ! avdec_h264 ! autovideosink sync=false


  


  It works but I go over my bandwidth limit if there is movement. I'm not sure if there is a way to limit bandwidth by setting a parameter here :

  


  'video/x-h264, width=800, height=600, framerate=30/1'


  


  From what I can find online, I have to use something like x264enc. I've followed tutorials but I can't get x264enc to work. it always outputs "Redistribute latency..." on both machines when run and it stays there.

  


  I've tried using x264enc like follows :

  


  gst-launch-1.0 rpicamsrc preview=false !  'video/x-raw, width=800, height=600, framerate=30/1' ! x264enc ! h264parse ! rtph264pay config-interval=1 pt=96 ! gdppay ! udpsink host=YOUR_PC_IP port=5000
gst-launch-1.0 rpicamsrc preview=false !  'video/x-raw, width=800, height=600, framerate=30/1' ! x264enc tune=zerolatency ! h264parse ! rtph264pay config-interval=1 pt=96 ! gdppay ! udpsink host=YOUR_PC_IP port=5000
gst-launch-1.0 rpicamsrc preview=false ! x264enc ! h264parse ! rtph264pay config-interval=1 pt=96 ! gdppay ! udpsink host=YOUR_PC_IP port=5000
gst-launch-1.0 rpicamsrc preview=false ! x264enc tune=zerolatency ! h264parse ! rtph264pay config-interval=1 pt=96 ! gdppay ! udpsink host=YOUR_PC_IP port=5000


  


  Based on tutorials, I would think some of those should work. Other threads say that tune=zerolatency fixes my problem. At least the ones with same output of "Redistribute latency..." I don't know what I'm doing wrong.

  


  Any help would be appreciated. Thanks !

  


• 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 :
