Fix JPEG decoding of an oddly encoded files on gen7/8 #530

Open digetx opened 3 years ago

digetx commented 3 years ago

Intel VA-API driver fails to decode couple JPEG files for me because of the offending implicit u8->int32 expansion in the code of the driver. This PR fixes the implicit integer expansion and decoding works properly now.

@digetx could you provide a sample JPEG file that fails to decode? I have a Haswell CPU and cannot find any JPEGs that would fail to decode locally.

Don't have those files anymore. IIRC, the fix was inspired by the FFMPEG swdec code.
