Fixed size of buffers for output bitstreams.
Fixed real bitrate value returned after changing parameters.
Fixed methods for flushing encoders.
Fixed methods of changing the bitrate "on the fly".
Fixed problem with setting very low bitrate in H264 encoders (soft and hard).
Extended IAVOQSEncoder interface, added methods for getting connection types and aspect ratio.
Corrected output pin class.
Corrected and extended property page.
Upgraded to IPP 2020.2

Fixed bitrate change for H264 and MPEG-2 soft encoders
Fixed property page, allowed fast bitrate change "on the fly" (enter a number + press Enter).
The size of DirectShow samples for very high bitrates and low FPS is increased.

Fixed bug with processing fields of interlaced frames.
Fixed bug with filter stopping due to error from the allocator when using some third-party decoders.
