b52b398c30 vc2enc: decrease default strictness level 
Given how incredibly limited the official specifications are (limiting all use
to only the most common broadcasting formats), permit all supported inputs
by default. This makes the encoder more useful.

f57f665183 vorbisenc: Apply and output correct length window and mdct 
Usage of blocksize, window, mode, and mdct indexes are switched from
default 0 to a default of 1 to better align with specs. A flag of 0
should correspond with short windows, a flag of 1 with long.

5a2ad7ede3 vorbisenc: Separate copying audio samples from windowing 
Audio samples are shifted around when copying from the frame queue so that
analysis can be done without negatively impacting calculation of the MDCT.

Window coefficients are applied to the current two overlapped windows
simultaneously instead of applying overlap for the next frame ahead of time.
This improves readability when applying windows of varying lengths.

b658b5399e vaapi_encode: Use gop_size consistently in RC parameters 
The non-H.26[45] codecs already use this form.  Since we don't
currently generate I frames for codecs which support them separately
to IDR, the p_per_i variable is set to infinity by default so that it
doesn't interfere with any other calculation.  (All the code for I
frames still exists, and it works for H.264 if set manually.)
