  That would indeed be one of the reasons, plus:
 * we'd need to make sure all elements in a standard playbin pipeline
can handle that kind of data
 * we'd need to have va-api specific elements to handle common features
like scaling, deinterlacing, mixing
 * we'd need to be careful about the lifetime of va-api specific data
 * pray ffmpeg doesn't change the layout of their va-api specific
buffers
 * ...
