• PHP-FFMpeg Error while opening encoder for output stream

  5 janvier 2019, par Valor_

  I’m trying to use this PHP-FFMpeg library, but I’m keep getting errors like

  Error while opening encoder for output stream #0:0

  This is my PHP code

  private function createTeaserVideos($fullVideoPath, $databasePath, $uploadPath) {
  
          $ffmpeg = FFMpeg::create([
  
              'ffmpeg.binaries' => '/usr/bin/ffmpeg',
  
              'ffprobe.binaries' => '/usr/bin/ffprobe',
  
              'timeout'          => 0,
  
          ]);
  
  
  
          $ffmpeg->getFFMpegDriver()->listen(new \Alchemy\BinaryDriver\Listeners\DebugListener());
  
          $ffmpeg->getFFMpegDriver()->on('debug', function ($message) {
  
              var_dump($message);
  
          });
  
  
  
          // Create teaser_video_thumb
  
          $videoNameThumb = $this->randomTimeString() . '-thumb.mp4';
  
          $video = $ffmpeg->open($fullVideoPath);
  
          $video
  
              ->filters()
  
              ->resize(new \FFMpeg\Coordinate\Dimension(400, 280))
  
              ->synchronize();
  
          $video->save(new \FFMpeg\Format\Video\X264('aac', 'libx264'), $uploadPath . $videoNameThumb);
  
      }

  So what I’m trying to do here. User uploads his video and I’m trying to resize it and create one smaller video for the preview. The problem that I’m keep getting it is

  I can’t figure out what is the problem or how to solve it. Can someone please help me out ? I’m using Ubuntu 16 and I have installed ffmpeg via apt-get install ffmpeg.
  If you need any additional infomations, please let me know and I will provide. Thank you

• Intel QuickSync error : Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

  30 novembre 2018, par Arie Syamsudin

  I want to make IPTV with a topology like this :

  Restream / source -----> IPTV server -----> User

  The problem at the moment is the question of bandwidth that is still large.

  Finally I announced by IPTV software providers to transcode with Intel QuickSync video and FFmpeg.

  I followed the steps given by the software provider at the following link :
  http://www.ezhometech.com/document/intel_ffmpeg.txt

  Which comes from the link below :
  https://www.intel.com/content/dam/www/public/us/en/documents/white-paper...

  I installed IPTV software on a laptop with an Intel processor, chipset and VGA.

• ffmpeg converting RTSP to HLS stops working after hours

  28 juin 2019, par lin wang

  I’m using ffmpeg to convert RTSP stream to HLS, here is the command :

  ffmpeg -rtsp_transport tcp -i rtsp ://address/9012120.smil -vcodec copy -acodec copy -fflags +genpts -f hls -hls_wrap 5 -hls_list_size 2 -hls_time 3 /dev/shm/live/1/v.m3u8

  It worked properly at the beginning, but after hours(sometimes 8 hours sometimes less),it just stopped updating .ts files but the ffmpeg process was still running, so the hls stream just stuck.
  Check the log, no error log at the moment of the converting stopping,but before that there were some warning logs as below :

  [hls @ 0x57602c0] Non-monotonous DTS in output stream 0:1 ; previous : 5957536600,
  current : 2744367719 ; changing to 5957536601. This may result in incorrect timestamps in the output file.

  Any idea how to fix this ?
