Comment (by jkqxz):
RAP_B_Bossen_1.bit works for me with libmfx.
It looks like libmfx barfs on files with missing profile information? All
of DBLK_*_VIXS_1.bit, ENTP_*_LG_*.bit, IPRED_C_Mitsubishi_2.bit,
TMVP_A_MS_2.bit and TSKIP_A_MS_2.bit have this problem and are therefore
technically invalid, but the libavcodec decoder handles this case so they
do work fine with VAAPI using the same hardware.
PICSIZE_D_Bossen_1.bin is 4216 samples wide, maybe libmfx has some problem
with that? There isn't anything else interesting about it as far as I can
tell (and it is intended to be a picture size test). It does work file
with VAAPI, so it's not a hardware issue.
Can you share the files
"MSFT/MSHDRef_Texture_SkinTones_08_320x240p24f_randomaccess_main.bin" and
"BBC/SteamLocomotiveTrain_2560x1600_60_10bit_crop_qp32.bin"?
