#11618: hwupload filter fails with "Cannot allocate memory" for VA-API on AMD RX
7900 XT (Navi 31) preventing H.264/HEVC hardware encoding initialization.
----------------------------------+----------------------------------
Reporter: CN | Type: defect

Summary of the bug: Fails to encode video files on Radeon hardware with
various methods. Gemini says 'The problem is not necessarily with the
h264_vaapi or hevc_vaapi encoder itself, but with the hwupload filter
failing to allocate memory on your VA-API device. This is a lower-level
issue than just a pixel format or encoder parameter problem.
This "Cannot allocate memory" error for hwupload when dealing with VA-API
on AMD GPUs (especially newer ones like Navi 3x) can indicate several
things'
