• ffmpeg 1FPS extraction call spits out infinite images until disk is bricked on poorly-encoded movie

  12 juillet 2017, par John Allard

  This is one of the oddest things I’ve ever seen while using ffmpeg.

  This is the scenario - we are getting video footage from a IONODE ION-E100 encoder, the footage is encoded in h264. I can view the footage fine in VLC, and I can copy it over to another video using ffmpeg and -c:v copy. The issue arises when I try and extract one FPS from the movie using the following command :

  ffmpeg -i testmovie.mp4 -r 1 -vf 640:-2 -q:v 18 -loglevel error /tmp/tmp/extraction_%04d.jpeg

  What this should do is go through the movie and extract one frame per second, then dump the frames to the files /tmp/tmp/extraction_0001.jpeg, /tmp/tmp/extraction_0002.jpeg, ..., /tmp/tmp/extraction_000X.jpeg. It should end when it reaches the end of the video.

  Now the odd thing that happens when I run this command is that it will run in a tight loop, writing tens or hundreds of thousands of images to the disk until the disk is full at which point the command fails. All of the extracted images are the exact same as one another.

  Here is the ffmpeg stats output on the video

  So my question is, why does this video break ffmpeg ? Why does ffmpeg get caught up in a tight loop extracting images without ever making any progres towards the end of the video ?

  (Basically add a bunch of animated overlays to the video)

  On PC this command takes about a second to execute (render speed is about 278 fps). But on Android device with Snapdragon 821 it takes about 10 seconds (about 30 fps).

  The curious thing is that whenever command is executing on PC, CPU load is around 90%, but on Android it’s less than 1% (see screenshot : initial spike is UI stuff plus loading binaries, afterwards ffmpeg was executing until 10 second mark)

  

  I tried executing the same command, but writing to /dev/null
  instead of the file :

  ffmpeg -y -i video.mp4 -ignore_loop 0 -i overlay.gif -filter_complex `
  
  >> "[0][1]overlay=x=mod((1080/4 + sin(t)*1080/4)\,1920):y=mod(t*300\,1080):shortest=1[res];`

  This reduced time by 3 seconds.

  I also tried replacing gif overlay with png overlay, but speed didn’t improve significantly.

  Here’s log of the command execution on Android :
