I have two videos (call them a.mov and b.mov) with the same width, height,
pixel format, etc.
ffprobe reports them as having 'yuv420p10le' pixel format.
If I do a trivial conversion:
ffmpeg -i a.mov out.mov
ffprobe reports out.mov as still being yuv420p10le.
But if I create a trivial

Hi,
You know it's confounding, I couldn't get avfoundation audio input to work at
all, and then tried a bunch of options to get to the weird issue you describe
(which I thought was maybe something to do with the clock source being
different) but then I went back to supplying no extraneous

Hi,
I am attempting to capture a webcam with audio on a MacBook pro (Catalina
10.15.6), but I am having trouble with the audio stream. The video part is
