• How to deal with "Buffer queue overflow, dropping." (ffmpeg)

  1er mai 2015, par whitesiroi

  Sometimes it works great and sometimes I’m getting this message
  [Parsed_overlay_0 @ 0x7f9520518800] [framesync @ 0x7f9521021e28] Buffer queue overflow, dropping.

  by running this command
  ffmpeg -i a1.mp4 -i watermark150x125.png -filter_complex 'overlay=10:10' output.mp4

  I tried different variation of "overlay" like overlay=W-w-5:H-h-5, overlay=10:main_h-overlay_h-10, overlay=main_w-overlay_w-10:main_h-overlay_h-10 - getting the same result.

  Here is the output of the ffmpeg command.

• How to get the output resolution after successful encode ?

  11 janvier 2021, par Daniel Birowsky Popeski

  I'm using fluent-ffmpeg and I'm already able to get the output resolution in the 'on end' event :

  


  createFfmpegCommand()
  .input(fs.createReadStream(readPath))
  .noAudio()
  .fps(30)
  .format('mp4')
  .videoCodec('libx264')
  .videoFilter([
   {filter: 'scale', options: '1920:1920:force_original_aspect_ratio=decrease'},
   {filter: 'setpts', options: '1.5*PTS'},
  ])
  .outputOption('-crf 30')
  .outputOption('-movflags frag_keyframe')
  .outputOption('-movflags +faststart')
  .output(mp4WriteStream)
  .on('start', () => console.log('processing started'))
  .on('error', err => console.error('err', err))
  .on('end', (_,res) => console.log('processing success',res))
  .run();


  


  However, i'd like it to be machine-readable (json or xml). Instead, it looks like this :

  Which doesn't let me be comfortable that my regex to extract the output resolution is always going to work.

  


  Also, I don't wanna make another call/fileread just to get the resolution. Mainly because my files are stored in S3, where ffprobe doesn't work.

  


• FFmpeg-Invalid PNG signature,Error while decoding stream,Invalid data found when processing input

  I am using below ffmpeg command to convert images to video-

  By what I understand is that there might be some image file which can be corrupt which causes ffmpeg to fail in creating video from images.Is there any way FFmpeg can ignore that corrupt image file and create video from other image files ? Is there any change i can make in command to prevent this failure ?
