• Why ffmpeg-split AVI movie freezes when played

  29 septembre 2015, par bl4ck5un

  I used ffmpeg to split AVI movies like

  ffmpeg -i input.avi -vcodec copy -acodec copy -ss 00:22:33 -to 1:2:3 out.avi
  

  But the output file out.avi is sometimes weird when played (in MPlayerX, for example) -- it will stop at the first frame, freezing like a picture, but if I drag the process bar forward, then continue playing at a different place, everything would be fine and the video just goes on smoothly.

  I have limited knowledge on AVI format and ffmpeg, can you guys point out what's the problem here? If it's a matter of kerFrame or what?

• Why JPEG image looks different in two videos ?

  28 septembre 2015, par user606521

  I have two frames:

  f1.jpg f2.jpg

  And I am creating two videos:

  ./ffmpeg -i ./f%d.jpg -r 30 -y m1.mp4 # both frames 1 and 2
  ./ffmpeg -i ./f2.jpg -r 30 -y m2.mp4 # only frame 2
  

  For some reason frame 2 looks different in these two videos

  Frame 2 from m1.mp4:

  It seems that frame 2 looks different when combined with frame 1 in a video. One thing I noticed that when dumping frames from m1.mp4 (two frames combined) there is a warning in ffmpeg output:

  [swscaler @ 0x7f7f9a000600] deprecated pixel format used, make sure you did set range correctly
  

  Also two frame images have same dimmensions (980x100) and their format seems to be same:

  $ file -b f1.jpg
  JPEG image data, JFIF standard 1.01, comment: "CS=ITU601??"
  $ file -b f2.jpg 
  JPEG image data, JFIF standard 1.01
  

  So why this is happening? I am struggling with this issue for quite a long time - for some reason some JPEGs somehow are in different "format?" than others and make mess in videos...

  You can download first two images included in this question and test commands on your own.

• Which pixel format for web mp4 video ?

  28 septembre 2015, par user606521

  I have to create video in mp4 format, and it seems that I can encode it with different pixel formats like yuv420p, yuv422p, yuvj422p. Which one I should use to maximize compatibility with most browsers/players?

• Two nearly identical ffmpeg commands, one works, the other freezes up

  28 septembre 2015, par dylanjha

  In both of these examples, I'm passing two inputs to ffmpeg applying a filter to the first input, and outputting it all to a .mp4.

  Example 1

  ffmpeg -y -threads 4 -ss 23.536 -t 44.854 -i .tmp/processing/vid-one.webm -ss 13.516 -t 54.874 -i .tmp/processing/vid-two.webm -filter_complex "[0]scale=320:-1,pad=2*iw:2*ih:0:120[left];[1]scale=320:-1[right];[left][right]overlay=main_w/2:120,scale=640:480" -shortest .tmp/processing/temp-23536-68390.mp4
  

  Example 2

  ffmpeg -y -threads 4 -ss 68.39 -t 3.646 -i .tmp/processing/vid-one.webm -ss 58.37 -t 13.666 -i .tmp/processing/vid-two.webm -filter_complex "[0]scale=320:-1,pad=2*iw:2*ih:0:120[left];[1]scale=320:-1[right];[left][right]overlay=main_w/2:120,scale=640:480" -shortest .tmp/processing/temp-68390-72036.mp4
  

  In the logging output I can get an idea of where it gets hung up.

  Output Example 1

  the output gets to this frame= line and it updates the output like this

• Add frame to video in specified position

  28 septembre 2015, par QUANGPHAT ĐINH

  I'm using Aforge libs to read and write video files (the libs is here: http://www.aforgenet.com/framework/features/ffmpeg.html).

  Now I want to export a specific frame to edit, then import it back to the video.

  I could export frame by frame but I don't know how to add it back to the video in specific frame. what should i do now ?
