• PHP FFMpeg error ffprobe failed to execute command "ffprobe.exe" "-help" "-loglevel" "quiet"

  5 mars 2017, par Michele

  I’m searching for a way to compress and convert uploaded videos on my site, I’m trying to use FFMpeg with this PHP basic code (on windows) :

  <?php
  
  ini_set('display_errors', 'On'); error_reporting(E_ALL);
  
  require("vendor/autoload.php");
  
  $ffmpeg = FFMpeg\FFMpeg::create(array(
  
      'ffmpeg.binaries'  => 'C:/inetpub/wwwroot/FFmpeg/ffmpeg.exe',
  
      'ffprobe.binaries' => 'C:/inetpub/wwwroot/FFmpeg/ffprobe.exe',
  
      'timeout'          => 3600, // The timeout for the underlying process
  
      'ffmpeg.threads'   => 12,   // The number of threads that FFMpeg should use
  
  ));
  
  $video = $ffmpeg->open('input.mp4');
  
  $video
  
      ->filters()
  
      ->resize(new FFMpeg\Coordinate\Dimension(320, 240))
  
      ->synchronize();
  
  $video
  
      ->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(10))
  
      ->save('frame.jpg');
  
  $video
  
      ->save(new FFMpeg\Format\Video\X264(), 'export-x264.mp4')
  
      ->save(new FFMpeg\Format\Video\WMV(), 'export-wmv.wmv')
  
      ->save(new FFMpeg\Format\Video\WebM(), 'export-webm.webm');
  
  ?>

  but I’m getting this error :

  Fatal error: Uncaught Alchemy\BinaryDriver\Exception\ExecutionFailureException: ffprobe failed to execute command "C:/inetpub/wwwroot/FFmpeg/ffprobe.exe" "-help" "-loglevel" "quiet" in C:\inetpub\wwwroot\site\vendor\alchemy\binary-driver\src\Alchemy\BinaryDriver\ProcessRunner.php:100 Stack trace: #0 C:\inetpub\wwwroot\site\vendor\alchemy\binary-driver\src\Alchemy\BinaryDriver\ProcessRunner.php(72): Alchemy\BinaryDriver\ProcessRunner->doExecutionFailure('"C:/inetpub/www...') #1 C:\inetpub\wwwroot\site\vendor\alchemy\binary-driver\src\Alchemy\BinaryDriver\AbstractBinary.php(209): Alchemy\BinaryDriver\ProcessRunner->run(Object(Symfony\Component\Process\Process), Object(SplObjectStorage), false) #2 C:\inetpub\wwwroot\site\vendor\alchemy\binary-driver\src\Alchemy\BinaryDriver\AbstractBinary.php(137): Alchemy\BinaryDriver\AbstractBinary->run(Object(Symfony\Component\Process\Process), false, NULL) #3 C:\inetpub\wwwroot\site\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\FFProbe\OptionsTester.php(61): Alchemy\Binary in C:\inetpub\wwwroot\site\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\FFProbe\OptionsTester.php on line 63

  what am I doing wrong ? there are better libraries ?

• ffmpeg using MediaCodec, avcodec_open2 says error code :-1 (0xffffffff) text : "Operation not permitted"

  11 mai 2017, par Miguel Del Amor

  I’m trying to use the Android API MediaCoded that have been supported by ffmpeg but while I try to open the codec I got "Operation not permitted" all times, I’ve tried some changes and I’ve tried to find examples without not luck.

  This is what I’m doing

  av_jni_set_java_vm(QAndroidJniEnvironment::javaVM(), NULL);
  
  
  
  av_register_all();
  
  avcodec_register_all();
  
  
  
  AVCodec *_codec(nullptr);
  
  AVCodecContext *_codecContext(nullptr);
  
  
  
  if (_codec == nullptr)
  
      _codec = avcodec_find_decoder_by_name("h264_mediacodec");
  
  
  
  if (_codecContext == nullptr)
  
      _codecContext = avcodec_alloc_context3(_codec);
  
  
  
  int ret = 0;
  
  if( (ret = avcodec_open2(_codecContext, _codec, NULL)) < 0 ) {
  
  
  
      char str[AV_ERROR_MAX_STRING_SIZE];
  
      memset(str, 0, sizeof(str));
  
      av_strerror(ret, str, sizeof(str));
  
  
  
      qDebug("avcodec_open2 \"%s\" error[code:%d text:\"%s\"]",_codec->long_name, ret, str);
  
  }

  And I’m getting this output

  avcodec_open2 "H.264 Android MediaCodec decoder" error[code:-1 text:"Operation not permitted"]

  What I’m doing wrong ?

• Sporadic "Error parsing Cues... Operation not permitted" errors when trying to generate a DASH manifest

  22 novembre 2023, par kshetline

  I have already-generated .webm audio and video files (1 audio, 3 video resolutions for each video I want to stream). The video has been generated not (directly) by ffmpeg, but HandbrakeCLI 1.7.0, with V9 encoding. The audio (which has never caused an error) is generated by ffmpeg using libvorbis.

  


  Most of the time ffmpeg (version 6.1) creates a manifest without any problem. Sporadically, however, "Error parsing Cues" comes up (frequently with the latest videos I've been trying to process) and I can't create a manifest. Since this is happening during an automated process to process many videos for streaming, the audio and video sources are being created exactly the same way whether ffmpeg succeeds or fails in generating a manifest, making this all the more confusing.

  


  The video files ffmpeg chokes on play perfectly well using VLC, and mediainfo doesn't show any problems with these files.

  


  Here's the way I've been (sometimes successfully, sometimes not) generating a manifest, with extra logging added :

  


  ffmpeg -v 9 -loglevel 99 \
  -f webm_dash_manifest -i '.\Sample Video.v480.webm' \
  -f webm_dash_manifest -i '.\Sample Video.v720.webm' \
  -f webm_dash_manifest -i '.\Sample Video.v1080.webm' \
  -f webm_dash_manifest -i '.\Sample Video.audio.webm' \
  -c copy -map 0 -map 1 -map 2 -map 3 \
  -f webm_dash_manifest -adaptation_sets "id=0,streams=0,1,2 id=1,streams=3" \
  '.\Sample Video.mpd'


  


  Here's the result when it fails :

  I don't know if I need different command line options, or whether this might be an ffmpeg or Handbrake bug. It has taken many, many hours to generate these video files (VP9 is painfully slow to encode), so I hate to do a lot of this over again, especially doing it again encoding the video with ffmpeg instead of Handbrake, as Handbrake is (oddly enough, considering it uses ffmpeg under the hood) noticeably faster.

  


  I have no idea what these "Cues" are that ffmpeg wants and can't parse, or how I would change them.
