• Transcoding with custom commands using streamio-ffmpeg

  14 avril 2017, par ACIDSTEALTH

  I’m trying to transcode a video file using streamio-ffmpeg with some custom commands, but nothing I try seems to work. I want to transcode the video with the following options :

  ffmpeg -i input.mp4 -vf
  
      "format=yuv444p,
  
       drawbox=y=ih/PHI:color=0x000000@0.4:width=iw:height=48:t=max,
  
       drawtext=font='OpenSans-Regular,Sans':text='CUSTOM TEXT':fontcolor=0xFFFFFF:fontsize=24:x=(w-tw)/2:y=(h/PHI)+th,
  
       format=yuv420p"
  
  -c:v libx264 -c:a copy -movflags +faststart output.mp4

  I’ve tried the following code combinations without success :

  1. Tried removing the line breaks and converting the command string to an array, following the instructions in the docs.

     video = FFMPEG::Movie.new('input.mp4')
     
     opts = %w(ffmpeg -i input.mp4 -vf "format=yuv444p, drawbox=y=ih/PHI:color=0x000000@0.4:width=iw:height=48:t=max, drawtext=font='OpenSans-Regular,Sans':text='CUSTOM TEXT':fontcolor=0xFFFFFF:fontsize=24:x=(w-tw)/2:y=(h/PHI)+th, format=yuv420p" -c:v libx264 -c:a copy -movflags +faststart output.mp4)
     
     video.transcode('output.mp4', opts)

     But this yields the error :

     [NULL @ 0x7f962100e200] Unable to find a suitable output format for 'ffmpeg'
     
     ffmpeg: Invalid argument
     
     from /Users/ACIDSTEALTH/.gem/ruby/2.3.0/gems/streamio-ffmpeg-3.0.2/lib/ffmpeg/transcoder.rb:112:in `validate_output_file'

  2. Tried stripping out the input file name and output file name since the gem seems to handle that for you.

     video = FFMPEG::Movie.new('input.mp4')
     
     opts = %w(-vf "format=yuv444p, drawbox=y=ih/PHI:color=0x000000@0.4:width=iw:height=48:t=max, drawtext=font='OpenSans-Regular,Sans':text='CUSTOM TEXT':fontcolor=0xFFFFFF:fontsize=24:x=(w-tw)/2:y=(h/PHI)+th, format=yuv420p")
     
     video.transcode('output.mp4', opts)

     Which returns this error :

     [NULL @ 0x7fd0a9008c00] Unable to find a suitable output format for 'drawbox=y=ih/PHI:color=0x000000@0.4:width=iw:height=48:t=max,'
     
     drawbox=y=ih/PHI:color=0x000000@0.4:width=iw:height=48:t=max,: Invalid argument
     
     from /Users/ACIDSTEALTH/.gem/ruby/2.3.0/gems/streamio-ffmpeg-3.0.2/lib/ffmpeg/transcoder.rb:112:in `validate_output_file'

  3. Tried removing the -vf flag and just running everything within the quotation marks.

     video = FFMPEG::Movie.new('input.mp4')
     
     opts = %w(format=yuv444p, drawbox=y=ih/PHI:color=0x000000@0.4:width=iw:height=48:t=max, drawtext=font='OpenSans-Regular,Sans':text='CUSTOM TEXT':fontcolor=0xFFFFFF:fontsize=24:x=(w-tw)/2:y=(h/PHI)+th, format=yuv420p)
     
     video.transcode('output.mp4', opts)

     This returns another error :

     [NULL @ 0x7fab8101fe00] Unable to find a suitable output format for 'format=yuv444p,'
     
     format=yuv444p,: Invalid argument
     
     from /Users/ACIDSTEALTH/.gem/ruby/2.3.0/gems/streamio-ffmpeg-3.0.2/lib/ffmpeg/transcoder.rb:112:in `validate_output_file'

  4. Tried removing the format arguments since ffmpeg is clearly complaining about those.

     video = FFMPEG::Movie.new('input.mp4')
     
     opts = %w("drawbox=y=ih/PHI:color=0x000000@0.4:width=iw:height=48:t=max, drawtext=font='OpenSans-Regular,Sans':text='CUSTOM TEXT':fontcolor=0xFFFFFF:fontsize=24:x=(w-tw)/2:y=(h/PHI)+th")
     
     video.transcode('output.mp4', opts)

     Again another error :

     [NULL @ 0x7fc7f880a800] Unable to find a suitable output format for 'drawbox=y=ih/PHI:color=0x000000@0.4:width=iw:height=48:t=max,'
     
     drawbox=y=ih/PHI:color=0x000000@0.4:width=iw:height=48:t=max,: Invalid argument
     
     from /Users/ACIDSTEALTH/.gem/ruby/2.3.0/gems/streamio-ffmpeg-3.0.2/lib/ffmpeg/transcoder.rb:112:in `validate_output_file'

  5. Tried building a hash from the command string and feeding that into the transcode method.

     video = FFMPEG::Movie.new('input.mp4')
     
     opts = {
     
         '-vf' => {
     
             format: 'yuv444p',
     
             drawbox: {
     
                 y: 'ih/PHI', color: '0x000000@0.4', width: 'iw', height: '48', t: 'max'
     
             },
     
             drawtext: {
     
                 font: 'OpenSans-Regular,Sans', text: snap.title, fontcolor: '0xFFFFFF', fontsize: '24', x: '(w-tw)/2', y: '(h/PHI)+th'
     
             },
     
             format: 'yuv420p'
     
         }
     
     }
     
     video.transcode('output.mp4', opts)

     I also tried a variation without the -vf flag :

     video = FFMPEG::Movie.new('input.mp4')
     
     opts = {
     
         format: 'yuv444p',
     
         drawbox: {
     
             y: 'ih/PHI', color: '0x000000@0.4', width: 'iw', height: '48', t: 'max'
     
         },
     
         drawtext: {
     
             font: 'OpenSans-Regular,Sans', text: snap.title, fontcolor: '0xFFFFFF', fontsize: '24', x: '(w-tw)/2', y: '(h/PHI)+th'
     
         },
     
         format: 'yuv420p'
     
     }
     
     video.transcode('output.mp4', opts)

  These both produced an output.mp4 video file but the output file was unchanged from the input. There was no text overlay.

  Nothing I try seems to work. What am I doing wrong here ?

  I have tried asking ChatGPT, Gemini, or Bing, and they always lead me into a loop of errors that cannot be resolved. This error only occurs when the song naturally finishes playing due to its duration. If the song is playing and I use the command !skip, the next song in the queue will play and function normally. I noticed that it seems like if a song ends naturally, the song queue is also cleared immediately. I hope someone can help me with this

  


• Understand your visitors by seeing where they click, hover, type and scroll, and replay their actions in a video

  18 mai 2017, par InnoCraft — Plugins

  Hi, this is Mike from InnoCraft, the company of the makers of Piwik Analytics which is used by over 1 million websites and apps in over 150 countries.

  I’m very proud to introduce you to our Heatmap & Session Recording feature which lets you analyze your visitors’ behaviour on a whole new level that was not possible before.

  With Heatmaps you can see where people think something is clickable but it is not, how far down the page do they scroll, whether they see your important buttons and Call To Actions, or even whether you can re-position your page layout to put the important content in more visible places. Both the mouse movements and all clicks are recorded and viewable on these new beautiful heatmap visualisations.

  With Session Recordings, you get to see a video showing exactly what a visitor did on your pages, including all mouse movements, scrolls, text typed in the keyboard, and more. Using these recordings you can improve the usability on your website, replace costly (and less effective) eye tracking sessions, and you can now see exactly what problems your visitors experience or how they behave on your website. This gives new insights and ability to understand what your users think.

  -> Read the rest of the story on the Heatmaps & Session Recordings Marketplace page.

  What does the new Heatmaps reports look like ?

  Here is below just a little preview of the new Heatmaps reports.

  1) Mouse move and Click Heatmaps

  

  2) A Scroll Heatmap

  

  What does the new Session Recording look like ?

  You can replay videos of exactly what your users did on your websites including mouse moves, scrolls, typing in forms, and more.

  1) Listing all recorded video sessions

  

  2) Playing a recorded video session
