#9173: Underestimated required buffer size (prores 8K)
-------------------------------------+-------------------------------------
Reporter: 0kajuna0 | Type: defect

-------------------------------------+-------------------------------------
Summary of the bug: While trying to encode an 8k PNG stream with prores,
ffmpeg crashes with "Underestimated required buffer size". This seems to
only happen if the PNG stream contains complex images. It seems to be fine
if the PNGs are mostly alpha.
This is not an issue with version 4.2.3. Seems to first appear with 4.3.
Tested with multiple Windows machines.
How to reproduce:
