20 | * encoder. Much of the firmware is read verbatim from a file, but some of | |
21 | * it concerning bitrate control and other things that can be configured at | |
22 | * run-time are generated dynamically. Note that the format headers | |
23 | * generated here do not affect the functioning of the encoder; they are | |
24 | * merely parroted back to the host at the start of each frame. | |
