• PHP ffmpeg convert GIF to MP4

  17 août 2020, par Eduard Unruh

  I use this code to convert GIFs to MP4 :

  


  $videoname = str_replace('.gif', '.mp4', $picname);
$ffmpeg = FFMpeg\FFMpeg::create(array(
    'ffmpeg.binaries'  => 'ffmpeg/bin/ffmpeg.exe',
    'ffprobe.binaries' => 'ffmpeg/bin/ffprobe.exe',
    'timeout'          => 6600, // The timeout for the underlying process
    'ffmpeg.threads'   => 12,   // The number of threads that FFMpeg should use
), $logger);

$video = $ffmpeg->open('memes/' . $folder . '/' . $picname);

$format = new \FFMpeg\Format\Video\X264('libvo_aacenc', 'libx264');
$format->setAdditionalParameters(array('-profile:v', 'baseline', '-pix_fmt', 'yuv420p'));

$video
    ->save($format, 'memes/' . $folder . '/' . $videoname);


  


  Some GIFs are getting converted but some not, this is the error message :

  What is all this crap ?

  


  Please help !

  


  EDIT :

  


  This is what I'm getting when running this code in cmd :

  So the error is height not divisible by 2 (636x357) I guess, but what would be the solution ?

  


• ffmpeg unable to get duration/bitrate of remote gif

  17 février, par Peter Xia

  I'm trying to get the duration of a gif.

  


  The command ffmpeg -i https://cdn.7tv.app/emote/01F6MZGCNG000255K4X1K7NTHR/4x.gif

  


  gives
Duration: N/A, start: 0.000000, bitrate: N/A

  


  However if i download the file and pass it in
ffmpeg -i 4x.gif

  


  it gives :
Duration: 00:00:07.92, start: 0.000000, bitrate: 1225 kb/s

  


  The issue seems limited only to gifs on 7tv site.

  


  

  • It works for other sites. (example : ffmpeg -i https://c.tenor.com/ULCY5B996-oAAAAd/tenor.gif).

  


  • It also works for other encodings of that image (exmaple ffmpeg -i https://cdn.7tv.app/emote/01F6MZGCNG000255K4X1K7NTHR/4x.avif)

  


  


  Here is the HTTP response header from 7tv site of that gif :

  Can someone help me understand ? Something spcecific to this site is causing ffmpeg to behave differently ?

  


• How to convert 7sec Video to Gif Android

  21 août 2014, par Donnie Ibiyemi

  Am making an app that convert shot video clips to Gif. i was wondering if there was a libary that directly converts videos to gifs on the Fly on Android.

  I’ve tried to extract all the frames of the video and encode them into a gif but am only getting the the first frame of the video. my code is below :

           public static final int GIF_DELAY_BETWEEN_FRAMES = 100;  
  
           public static final float SPEED_RATIO = 1.1f; 
  
  
  
           Uri videoFileUri=Uri.parse(mOutputFile.toString());
  
          FFmpegMediaMetadataRetriever retriever = new FFmpegMediaMetadataRetriever();
  
          retriever.setDataSource(mOutputFile.getAbsolutePath());
  
           rev = new ArrayList<bitmap>();
  
          MediaPlayer mp = MediaPlayer.create(RecorderActivity.this, videoFileUri);
  
           int millis = mp.getDuration();
  
           for(int i=1000000;itest.gif");
  
              outStream.write(generateGIF());
  
              outStream.close();
  
           }catch(Exception e){
  
              e.printStackTrace();
  
           }
  
  
  
  
  
          public byte[] generateGIF() {
  
          ByteArrayOutputStream bos = new ByteArrayOutputStream();
  
          AnimatedGifEncoder encoder = new AnimatedGifEncoder();
  
          encoder.setDelay((int)(GIF_DELAY_BETWEEN_FRAMES * (1 / SPEED_RATIO)));
  
          encoder.start(bos);
  
          for (Bitmap bitmap : rev) {
  
              encoder.addFrame(bitmap);
  
          }
  
          encoder.finish();
  
          return bos.toByteArray();
  
       }
  
  </bitmap>

  Please help me guys...thanks
