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

    12 septembre 2019, 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.

  • Get stdout from an idle background application in Windows

    24 septembre 2016, par Joe

    I have an ffmpeg.exe process that appears to be hung - it hasn’t done anything for several days. It was started by exec() in PHP, so is running in the background and has no window.

    I would like to know what caused it to stop/hang.

    Is there anyway to get what it has written to stdout ?
