Video output Full HD (1920x1080) results in crash #30

widovanheemstra commented 7 years ago

I tried to capture a video while having the screen size set to Full HD resolution. When I start the code it crashes and directs to the ffmpeg.txt log file.

I'm running processing 3.2.3 on Windows 7 Enterprise with a static ffmpeg file dowloaded. If I reduce the screen size to (1280x720) a video is created.

Hi, thanks for the bug report. The error is shown at the end of the text you pasted: "height not divisible by 2 (1920x1059)".

Even though you thought your display was 1920x1080, it's actually 1920x1059. And some video formats don't accept odd heights. If you actually used 1920x1080 it should work, or even 1920x1058.

I have to think how to deal with odd heights. I guess I could use a flag to tell the program to skip the last row of pixels. For now I will add it to the FAQ.
