• php_ffmpeg some error and solutions

  26 mars 2018, par sonam Sharma

  I have successfully installed php_ffmpeg in my new project with the help of a guy on stackoverflow.com.
  I can do the basic jobs like extracting a frame out of a video
  but when I try to convert the video to another format I get this error :

  Fatal error : Uncaught exception ’Alchemy\BinaryDriver\Exception\ExecutionFailureException’
  with message ’ffprobe failed to execute command "C :\ffmpeg\bin\ffprobe.EXE"
  "sample3.mp4" "-show_streams" "-print_format" "json"’ in
  C :\wamp\www\raidpipe\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\FFProbe.php on line 244

  Alchemy\BinaryDriver\Exception\ExecutionFailureException :
  ffprobe failed to execute command "C :\ffmpeg\bin\ffprobe.EXE"
  "sample3.mp4" "-show_streams" "-print_format" "json" in
  C :\wamp\www\raidpipe\vendor\alchemy\binary-
  driver\src\Alchemy\BinaryDriver\ProcessRunner.php on line 100

  FFMpeg\Exception\RuntimeException :
  Unable to probe sample3.mp4 in
  C :\wamp\www\raidpipe\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\FFProbe.php on line 244

  I have used this code in my test page :

   <?php
  
   require 'vendor/autoload.php';
  
   $ffmpeg = FFMpeg\FFMpeg::create();
  
   $video = $ffmpeg->open('test/sample3.mp4');
  
   $video
  
  ->filters()
  
  ->resize(new FFMpeg\Coordinate\Dimension(320, 240))
  
  ->synchronize();
  
    $video
  
  ->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(19))
  
  ->save('test/clip/frame123.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');
  
   ?>

  When I run this code it gives me the frame without any error

   require 'vendor/autoload.php';
  
    $ffmpeg = FFMpeg\FFMpeg::create();
  
    $video = $ffmpeg->open('test/sample3.mp4');
  
    $video
  
  ->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(19))
  
  ->save('test/clip/frame123.jpg');

  Please suggest me a way to convert the video by using the php_ffmpeg
  i need the video to be converted to some basic formats which can be supported by all the browsers and also please let me know is it a good practice to use exc (execute) in php ??

  I got the above code from this link

• spawn ffmpeg in nodejs and pipe to express's response

  18 décembre 2017, par ViGi

  i am spawning ffmpeg and pipe it’s output (the video stream i want) to express’s response object like this :

  app.get('/stream', (req, res) => {
  
      let _url = req.query.url;
  
  
  
      if(_url){   
  
  
  
          res.writeHead(200, {
  
              'Access-Control-Allow-Origin': '*',
  
              'Connection': 'Keep-Alive',
  
              'Content-Type': 'video/mp4'
  
          });
  
  
  
          // transcode rtsp input from ip-cam to mp4 file format (video: h.264 | audio: aac)
  
          let ffmpeg = child_process.spawn("ffmpeg",[
  
              "-probesize","2147483647",
  
              "-analyzeduration","2147483647",
  
              "-i", _url,
  
              "-vcodec","copy",
  
              "-f", "mp4",            
  
              "-movflags","frag_keyframe+empty_moov+faststart",
  
              "-frag_duration","3600",
  
              "pipe:1"              
  
          ]);         
  
  
  
  
  
          // redirect transcoded ip-cam stream to http response
  
          ffmpeg.stdout.pipe(res);
  
  
  
          // error logging
  
          ffmpeg.stderr.setEncoding('utf8');      
  
          ffmpeg.stderr.on('data', (data) => {
  
              console.log(data);
  
          });
  
      }
  
      else{
  
          res.end();
  
      }

  so far it’s working like a charm.
  however somewhere in there seems to be a cap. i can get only 3 streams running at the same time. when a 4th spawn occurs the 4th thread will block one of the cpu cores :

  

  and naturally the 4th stream does not reach the browser..
  has somebody any idea of what am i missing ?

  EDIT : it’s not tied to the fact that i am running the nodejs project on the raspberry pi. it also behaves the same way on my windows 10 machine
