• ffmpeg with Quick Sync Video (qsv) gets stuck

  28 avril 2023, par Juliano B. Nequirito

  I've compiled ffmpeg in an Arch Linux distribution with support to Intel Quick Sync Video. But ffmpeg gets stuck when I try to run it :

  


  $ ffmpeg -debug -hwaccel qsv -qsv_device /dev/dri/renderD128 -c:v h264_qsv -i test_video.mp4 -c:v hevc_qsv output.mp4

  CPU starts being used intensively and then nothing happens.
Does anybody have any clue on it ?

  


  I have an Intel i7-8550U (8th gen Kaby Lake) processor with 4 cores (8 threads).

  


  I have also used these options to ffmpeg, getting the same results :

  


  ffmpeg -loglevel debug -init_hw_device qsv=hw -filter_hw_device hw -hwaccel qsv -hwaccel_output_format qsv -i test_video.mp4 -vf 'format=qsv,hwupload=extra_hw_frames=64' -c:v hevc_qsv -f mp4 output.mp4


  


  With VAAPI, transcoding runs flowlessly :

  


  ffmpeg -init_hw_device vaapi=intel:/dev/dri/renderD128 -hwaccel vaapi -hwaccel_output_format vaapi -hwaccel_device intel -filter_hw_device intel -i test_video.mp4 -c:v hevc_vaapi -f mp4 output.mp4


  


• Heroku : FFMpeg installed but php worker can't find it

  4 décembre 2019, par Greco Jonathan

  Context

  I’ve a RabbitMQ’s queue that contains AMQPMessage, those messages are referencing a video that needs to be treated (cut essentially and encoded in x264 also)

  Here’s the code that cause the issue (pretty straightforward)

          $ffprobe = FFProbe::create([
  
              'ffmpeg.binaries'  => '/usr/bin/ffmpeg',
  
              'ffprobe.binaries' => '/usr/bin/ffprobe',
  
          ]);

  Error Message

  TL ;DR :
  Error: "Unable to load FFProbe"

  [2019-12-03 14:55:07] messenger.ERROR : Error thrown while handling message App\Api\Message\AMQPvideoFFMPEG. Sending for retry #1 using 1000 ms delay. Error : "Unable to load FFProbe" "message" :"[object] (App\Api\Message\AMQPvideoFFMPEG : {})","class" :"App\Api\Message\AMQPvideoFFMPEG","retryCount":1,"delay":1000,"error" :"Unable to load FFProbe","exception" :"[object] (Symfony\Component\Messenger\Exception\HandlerFailedException(code : 0) : Unable to load FFProbe at /app/vendor/symfony/messenger/Middleware/HandleMessageMiddleware.php:80, FFMpeg\Exception\ExecutableNotFoundException(code : 0) : Unable to load FFProbe at /app/vendor/php-ffmpeg/php-ffmpeg/src/FFMpeg/Driver/FFProbeDriver.php:50, Alchemy\BinaryDriver\Exception\ExecutableNotFoundException(code : 0) : Executable not found, proposed : /usr/bin/ffprobe at /app/vendor/alchemy/binary-driver/src/Alchemy/BinaryDriver/AbstractBinary.php:160)" []

  Configuration & tests

  On Heroku I’ve 2 dynos :

  - web $(composer config bin-dir)/heroku-php-nginx -C config/packages/dev/heroku_nginx.conf public/
  
  - worker php bin/console messenger:consume ffmpeg 

  On this platform, I’ve also 3 buildpacks, look below, with this specific buildpack :

  

  To make sure that all is available here’s the results of my checks :

  All good !

  Disclaimer

  This code is working well on another platform (handled by kubernetes), so it may need some adjustments with heroku. But can’t find it.

  Why this error since my configuration is not showing any missconfigurations ? What am I missing here ?

• Convert wmv to mp4 with ffmpeg failing

  10 janvier 2012, par Morph

  I've seen quite a few posts on this, but I can't piece together whether I am doing things right, wrong, or need to download more stuff. I am converting from wmv to mp4 without complaints, but then when I go to play it on the browser window (HTML5) the player just turns grey and blanks out the controls.

  Installing ffmpeg I do

  ./configure --disable-yasm ; make ; make install

  Unless I include the disable yasm it wont go any further. Then I do

  ffmpeg -i myvideo.wmv myvideo.mp4

  All good so far. In my html source I have :

    <video width="320" height="240" controls="controls">
  
    <source src="myvideo.mp4" type="&#39;video/mp4;" codecs="avc1.42E01E, mp4a.40.2"></source>
  
    Your browser does not support the video tag.
  
    </video>

  I am playing this in Chrome 15 and ffmpeg -v is

  ffmpeg version 0.8.6, Copyright (c) 2000-2011 the FFmpeg developers
  
  built on Dec  1 2011 15:42:06 with gcc 4.1.2 20080704 (Red Hat 4.1.2-51)
  
  configuration: --disable-yasm
  
  libavutil    51.  9. 1 / 51.  9. 1
  
  libavcodec   53.  7. 0 / 53.  7. 0
  
  libavformat  53.  4. 0 / 53.  4. 0
  
  libavdevice  53.  1. 1 / 53.  1. 1
  
  libavfilter   2. 23. 0 /  2. 23. 0
  
  libswscale    2.  0. 0 /  2.  0. 0

  So I get the HTML5, click on it to play the movie but then the control bar greys out, leaving the play button, but then the play button cannot be clicked and nothing plays.

  Is there something wrong with what I have done above ? Do I need to download some separate mp4 driver and compile it ? I see people referring to h.264 but I thoughts ffmpeg had that already included...
