• av_interleaved_write_frame() : Connection reset by peer mjpeg : What is wrong with mjpeg stream, ffserver and ffplay ?

  31 décembre 2016, par Ilya Yevlampiev

  I’m creating mjpeg stream from image files using ffmpeg and write it to ffserver’s feed :

  sudo ffmpeg -loop 1 -i fon.jpeg -vcodec mjpeg -f mjpeg http://localhost:8090/feed1.ffm

  So, what is wrong in this streaming example, if I have no problem when I substitute streams to the files ?

  I create a mjpeg file using the same parameters 9i.e. file is an output insteadof stream)

  So, what is the configuration issue for ffserver, or may be it is a bug of the ffserver ?

  UPD. I have realized, that i fed file1.ffm instead of file.ffm ; that caused some ffserver problem :

  This captures the screen on my mac. To the best of my knowledge, this creates a lossless file and I have compared screen shots that confirm this.
  The next step is where I think I have an issue.
  Because I want to run the compression on raw RGB data I need to convert the MKV to an RGB file ;

  ffmpeg -i ~/Desktop/RGB.mkv -c:v rawvideo -pix_fmt rgb24 -crf 0 -ss 00:00:03 -to 00:02:01 -q 0 -y ~/Desktop/out.rgb

  But here I have pixel variance. My guess is there is a RGB-YUV-RGB conversion happening somewhere but I am not smart enough to work out where.
  If any of you can help I would forever grateful.

  Here is a picture of the two stills side by side that shows the differences ;

  If you need anything more I can post it also.

• Ffmpeg concat images doesn't finish all images

  18 septembre 2015, par Simon

  I’m trying to do a simple task with ffmpeg. I’ve pre-generated about 100 png images (all same resolution) and separetely generated a list of them to be used by ffmpeg to concat them into a video. Each frame is likely to be used more than once. The output video is to be about 10,000 frames.

  The problem is that ffmpeg stops at about frame 4000 with no error. The final video works with no error.

  ffmpeg command :

  ffmpeg  -f concat -i frame_list.txt -vf fps=10 output.mov

  frame_list.txt sample :

      file 'frame_0045.png'
  
      file 'frame_0046.png'
  
      file 'frame_0047.png'
  
      file 'frame_0046.png'
  
      file 'frame_0047.png'
