DESCRIPTION

Data format definitions are non-standard and resulting in color components being swapped if wrong assumption is made in software.

To configure data packing/unpacking logic for each active data channel, the VPDMA (in the VPE, and VIP) relies on the 'data type' value in the channel's data transfer descriptor. Due to mismatches in the component order directions between what the VPDMA specifies and what commonly used image identifiers expect, color components can be swapped in the display and in the video/image data written out to the memory for some RGB and YUV data types.

GUIDELINES

Software drivers should remap custom formats to the desired industry standard formats and/or treat data as word/byte swapped as appropriate. See also Device TRM for full explanation of data formats.
