[PATCH 0/3] MR8812: winegstreamer: Support 2D sample buffer.

[Conor McCarthy (＠cmccarthy)]

Performance issues can occur when a video output sample has a 2D buffer,
because winegstreamer currently outputs only to a linear buffer, which
must then be copied into the 2D buffer. Worse, a linear lock of the 2D
buffer requires the current contents to be copied to a linear buffer,
even when we intend to overwrite it, because MF linear buffers do not
support write-only locking.
