[FFmpeg-devel] [PATCH 1/7] avcodec/dxvenc: Don't cast const away

[Connor Worley]

Thanks for fixing this :)
Are you planning more work on the DXV side following this? I have a patch
to follow that replaces `decompress_texture_thread` with purely
texdsp calls (HQ BC4/BC5 textures can be decompressed with
`rgtc1u_gray_block`).
