History

Connor Worley d5aaed9d4c lavc/dxv: align to 4x4 blocks instead of 16x16 ... The previous assumption that DXV needs to be aligned to 16x16 was erroneous. 4x4 works just as well, and FATE decoder tests pass for all texture formats. On the encoder side, we should reject input that isn't 4x4 aligned, like the HAP encoder does, and stop aligning to 16x16. This both solves the uninitialized reads causing current FATE tests to fail and produces smaller encoded outputs. With regard to correctness, I've checked the decoding path by encoding a real-world sample with git master, and decoding it with ffmpeg -i dxt1-master.mov -c:v rawvideo -f framecrc - The results are exactly the same between master and this patch. On the encoding side, I've encoded a real-world sample with both master and this patch, and decoded both versions with ffmpeg -i dxt1-{master,patch}.mov -c:v rawvideo -f framecrc - Under this patch, results for both inputs are exactly the same. In other words, the extra padding gained by 16x16 alignment over 4x4 alignment has no impact on decoded video.
