• Advice on how to specify length of animated GPX video with ffmpeg/image2pipe

  21 mai 2019, par Chris Olin

  I’m working on a personal project involving an action camera that records GPS data alongside video from an image sensor. I found an open source projected on GitHub called ’trackanimation’ that uses a colored marker to trace the GPX path on a OpenStreetMaps overlay, but it appears that the project has been abandoned. I’m trying to sync the trackanimation video to the image sensor video, but when I try using video editing software to slow the GPX video down to 1%, it still ends up being shorter than the image sensor video. I’ve tried messing with the baked in ffmpeg command in make_video(), but still can’t get the output video to be as long as I want it to be.

  I started digging into the library source to see how the video was being created, tried tweaking a couple things to no avail.

  import trackanimation
  
  from trackanimation.animation import AnimationTrack
  
  
  
  gpx_file = "Videos/20190516 unity ride #2.mp4.gpx"
  
  gpx_track = trackanimation.read_track(gpx_file)
  
  
  
  fig = AnimationTrack(df_points=gpx_track, dpi=300, bg_map=True, map_transparency=0.7)
  
  fig.make_video(output_file="Videos/1-11trackanimationtest.mp4", framerate=30, linewidth=1.0)

      def make_video(self, linewidth=0.5, output_file='video', framerate=5):
  
          cmdstring = ('ffmpeg',
  
                       '-y',
  
                       '-loglevel', 'quiet',
  
                       '-framerate', str(framerate),
  
                       '-f', 'image2pipe',
  
                       '-i', 'pipe:',
  
                       '-r', '25',
  
                       '-s', '1920x1080',
  
                       '-pix_fmt', 'yuv420p',
  
                       output_file + '.mp4'
  
                       )

  I expect that I should be able to linearly "slow" the GPX video to a dynamic value based on the length of the video and the length I want it to be.

• Php FFMPEG request timout

  28 mars 2015, par Dev

  I am using Laravel 4.2.

  I am working on a project of uploading video. The uploaded video should be played in most devices that I am using php-ffmpeg package from the git-hub.

  The requirement is the transcoding should be done in background. I am using WAMP 2.5.

  What am I doing is, after upload I am firing an asynchronous ajax request that transcode the video and after successful completion it should insert a record into database containing video name, path etc.

  The problem is if I upload a large size video, then I am facing error Maximum execution time of 120 seconds exceeded.

  I know the possible solution is setting max_timelimit in php.ini but I don’t think it is a feasible solution because if there will be larger video, the same error will occurred again.

  Is there any technique that I can bypass this transcoding process in background ?

  My code is as below :

  try{
  
              $video_id = Input::get('video_id');
  
              $video_path = Input::get('video_path');
  
  
  
              $path = '/video/'.date('Y').'/'.date('m');
  
              $path .= '/';
  
              $explode_filename  = explode("/",$video_path);
  
              $save_filename = $explode_filename[sizeof($explode_filename)-1];
  
  
  
              $ffmpeg = FFMpeg\FFMpeg::create(array('timeout'=>0));
  
              $video = $ffmpeg->open($video_path);
  
  
  
              $format = new CustomVideo();
  
              $format->setKiloBitrate(1000)
  
                      ->setAudioChannels(2)
  
                      ->setAudioKiloBitrate(256);
  
  
  
              $video->save($format, public_path().$path.$save_filename); 
  
              //saving video
  
  
  
              Video::where('id', '=', $video_id)->update(array('is_transcoded' => 1,'video_url'=>url($path.$save_filename)));
  
          }
  
          catch (Exception $ex){
  
             return Response::json (["Message"=>$ex->getMessage(), "code"=>$ex->getCode(), "trace"=>$ex->getTrace()]);
  
          }
