While performance is indeed affected (tested with GStreamer), 4K playback still works as long as you don't operate in lock step and keep at least 1 frame ahead of time in the decode queue. After discussion with ChromeOS members, it would seem that their implementation indeed used to synchronously decode each frame, so this hack was simply compensating for their code being less efficient. In my opinion, this hack should not have been included upstream.

When frame_mbs_only_flag is 0 the height in mbs should be height of the field instead of height of frame. Validate pic_width_in_mbs_minus1 and pic_height_in_map_units_minus1 against OUTPUT buffer resolution and use these values to configure HW. The validation is happening in both try_ctrt() and start() since it is otherwise possible to trick the driver during initialization by changing the OUTPUT format after having set a valid control.

While most of the code is derived from Rockchip and VSI reference code, the reduction of the reference list to 16 entries was found by trial and errors. The list consists of all the references with the opposite field parity. The strategy is to deduplicate the reference picture that points to the same storage (same index). The choice of opposite parity has been made to keep the other field of the current field pair in the list. This method may not be robust if a field was lost.
