/* For reverse playback we use a technique that can be used for
* any keyframe based video codec.
*
* Input:
* Buffer decoding order: 7 8 9 4 5 6 1 2 3 EOS
* Keyframe flag: K K
* Discont flag: D D D
*
* - Each Discont marks a discont in the decoding order.
* - The keyframes mark where we can start decoding.
*
* First we prepend incomming buffers to the gather queue, whenever we receive
* a discont, we flush out the gather queue.
*
* The above data will be accumulated in the gather queue like this:
*
* gather queue: 9 8 7
* D
*
* Whe buffer 4 is received (with a DISCONT), we flush the gather queue like
* this:
*
* while (gather)
* take head of queue and prepend to decode queue.
* if we copied a keyframe, decode the decode queue.
*
* After we flushed the gather queue, we add 4 to the (now empty) gather queue.
* We get the following situation:
*
* gather queue: 4
* decode queue: 7 8 9
*
* After we received 5 (Keyframe) and 6:
*
* gather queue: 6 5 4
* decode queue: 7 8 9
*
* When we receive 1 (DISCONT) which triggers a flush of the gather queue:
*
* Copy head of the gather queue (6) to decode queue:
*
* gather queue: 5 4
* decode queue: 6 7 8 9
*
* Copy head of the gather queue (5) to decode queue. This is a keyframe so we
* can start decoding.
*
* gather queue: 4
* decode queue: 5 6 7 8 9
*
* Decode frames in decode queue, store raw decoded data in output queue, we
* can take the head of the decode queue and prepend the decoded result in the
* output queue:
*
* gather queue: 4
* decode queue:
* output queue: 9 8 7 6 5
*
* Now output all the frames in the output queue, picking a frame from the
* head of the queue.
*
* Copy head of the gather queue (4) to decode queue, we flushed the gather
* queue and can now store input buffer in the gather queue:
*
* gather queue: 1
* decode queue: 4
*
* When we receive EOS, the queue looks like:
*
* gather queue: 3 2 1
* decode queue: 4
*
* Fill decode queue, first keyframe we copy is 2:
*
* gather queue: 1
* decode queue: 2 3 4
*
* Decoded output:
*
* gather queue: 1
* decode queue:
* output queue: 4 3 2
*
* Leftover buffer 1 cannot be decoded and must be discarded.
