Hi, I am porting the cook decoder from Rockbox to my hardware. Since my hardware has no std library support, I am converting all run time calculations to static predefined tables. while doing so, I happen to see that basically all the calculation done is based on samples_per_Frame and which could be (256,512,1024). So for every table calculation, I am caluclation 3 different tables for each frame size. Is it alright? I really couldn't find Real Cook decoder specification (As how many samples/frame, etc..) anywhere on Internet.
Is it safe to assume that the samples_per_frame can't be anything other then the mentioned 3. I happen to see that if it is not among these three, cook_decode_init() will return -1. Please provide your inputs.
