tiled formats

[frank roku]

We would like to use libyuv, but the qualcomm decoder produces a tiled format that we are having trouble understanding

Has anyone figured how to move tiled formats into standard formats so that we can then use libyuv?

Thanks,

Frank

Looks like you found the answer is here

http://gitorious.org/atrix-aosp/frameworks_base/blobs/8f901240ab7c98ad48542b99342d02ed84937395/media/libstagefright/colorconversion/ColorConverter.cpp

YUV420PackedSemiPlanar means NV12

Theres a Y plane followed by a 1/2 width by 1/2 height UV channel.

64x32Tile means there is a 64x32 block in NV12.

So 64x32 Y plane and 32x16 UV plane.

I dont know what 2m8ka means.

Looks like the content in the tile is zigzag order.
