 Unfortunately, not sure how to reproduce with a standalone ffmpeg code,
 but within our iOS app, we use ffmpeg decoder (currently on n4.2.4).
 Hardware decoding worked fine; then the M1 iPad we test with was upgraded
 from iOS 14 to iOS 15, and now the decoder consistently fails with "[h264
 @ 0x10c014000] hardware accelerator failed to decode picture" on the same
 source material.
