  • FFMPEG Concat filter - Output video skips second file

    16 octobre 2018, par Rune Aspvik

    I am using the ffmpeg concat filter to join video files. I am aware the files must be exactly the same format for concat to work without encoding. However, the output of these two files are not seemless. The video will stop when it switches to second video file.

    Here is the output of the two video files.

    The command I’m using for the concat is :

    ffmpeg -f concat -safe 0 -i /Users/Aspvik/Desktop/files.txt -codec copy -y /Users/Aspvik/Desktop/video.mp4

    Can anyone see what could be wrong ?

  • Why won't Apple players play this ffmpeg-generated video ? [duplicate]

    3 octobre 2018, par Giuseppe

    This question already has an answer here :

    I generated a short mp4 from a stack of PNG images, with no audio, like so :

    ffmpeg -r 24 -i t-%03d.png -r 24 -c:v libx264 test.mp4

    On my MacBook, the resulting video plays just fine with VLC or Chrome. With iTunes or Final Cut Pro, on the other hand, the progress bar moves as if playing was in progress, but the screen is blank. Finally, Safari and QuickTime complain that the format is invalid.

    Here is ffprobe’s output :
