// the component may change the configured color format to an optimized format.
// Additionally, when allocating these buffers for flexible usecase, the framework
// will set the SW_READ/WRITE_OFTEN usage flags. In this case (if bUsingNativeBuffers
// is OMX_TRUE), the component shall fill out the MediaImage information for the
// scenario when these SW-readable/writable buffers are locked using gralloc_lock.
// Note, that these buffers may also be locked using gralloc_lock_ycbcr, which must
// be supported for vendor-specific formats.
