Tyler Jones	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. Signed-off-by: Tyler Jones <tdjones879@gmail.com> Reviewed-by: Rostislav Pehlivanov <atomnuker@gmail.com>	8 years ago

Mark Thompson	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.) (cherry picked from commit `6af014f402`)	8 years ago
