/*
|
|
* - Principles of Operation -
|
|
*
|
|
* The CrystalHD decoder operates at the bitstream level - which is an even
|
|
* higher level than the decoding hardware you typically see in modern GPUs.
|
|
* This means it has a very simple interface, in principle. You feed demuxed
|
|
* packets in one end and get decoded picture (fields/frames) out the other.
|
|
*
|
|
* Of course, nothing is ever that simple. Due, at the very least, to b-frame
|
|
* dependencies in the supported formats, the hardware has a delay between
|
|
* when a packet goes in, and when a picture comes out. Furthermore, this delay
|
|
* is not just a function of time, but also one of the dependency on additional
|
|
* frames being fed into the decoder to satisfy the b-frame dependencies.
|
|
*
|
|
* As such, the hardware can only be used effectively with a decode API that
|
|
* doesn't assume a 1:1 relationship between input packets and output frames.
|
|
* The new avcodec decode API is such an API (an m:n API) while the old one is
|
|
* 1:1. Consequently, we no longer support the old API, which allows us to avoid
|
|
* the vicious hacks that are required to approximate 1:1 operation.
|
