• How to change size of watermark image and set Size and Aspect Ratio of Video using fluent-ffmpeg ?

  12 avril 2021, par Kirasiris

  Does anyone knows how to change the size of the watermark image ? ; secondly I tried to use complexFilter() with the size() and aspect() methods but it throws an error of complex-filter can not be used with complexFiltergraph in the same input stream ?

  


  This is my code :

  


  await ffmpeg('tmp/' + file.name)
  .input(waterMarkImage)
  .videoFilter([
    'overlay=10:10',
    'scale=1280:720',
    'aspect=16:9',
    'crop=1280:554:0:90',
  ])
  .output(key)
  .on('progress', function (progress) {
    console.log('Processing: ' + progress.percent + '% done')
  })
  .on('end', function (stdout, stderr) {
    console.log('Finished')
    fs.unlink(dir + file.name, function (err) {
      if (err) throw err
      console.log('File deleted')
    })
  })
  .on('error', function (err) {
    console.log('an error happened: ' + err.message)
    fs.unlink(dir + file.name, function (err) {
      if (err) throw err
      console.log('File deleted')
    })
  })
  .save(dir + key)


  


  Thanks.

  


• avcodec/svq3 : Don't copy watermarked frame data twice

  avcodec/svq3 : Don't copy watermarked frame data twice
  The SVQ3 decoder modifies the input bitstream at two places.
  
  One of them is only reached when the file is watermarked.
  
  Therefore commit 2264c1108135380c49fdf0aef97520bf77a6ed37
  
  made a copy of all the frame data in this case.
  But there is a second possibility for modifying the frame and
  
  therefore Libav commit 1098f5c0495c61a98d4ff6b8e24c17974d4bace5
  
  made the decoder always copy the data. This of course makes
  
  the additional copy for watermarked frames redundant, but it hasn't
  
  been removed. This commit does so.

• Watermark using FFMpeg

  9 mars 2021, par 0tonin

  I am using FFMpeg to add a watermark to a 30min video. Therefore, I used the following code :

  


  ffmpeg -i video1.avi -i watermark.png -filter_complex "overlay=10:1O" test1.avi

  


  However, the output is just a 5min video with worse quality. How can I fix this issue ?

  


  Thank you very much for your help !
