Summary of the bug:
so i get a strange bug where ffmpeg crashes from time to time.
this especially happens when i use a resolution of 1024x576.
i have a sample here which includes a bat file with the command, the video
file and the ffmpeg version.
https://sharing.rainbowdash.cc/testencode_short.7z
i also have the video file separate here:
https://sharing.rainbowdash.cc/ffmpegbug/input_short.mkv
it crashes just before the credits begin.
i tested it both on a ryzen system and an older intel system, on windows
10 (64bit).
both produce this error. maybe its a problem of my command line, but i
think ffmpeg should maybe prevent this command then.
How to reproduce:
{{{
