#7526: VAAPI HEVC Encoder Bitrate parameter no longer works in Master compared
to
4.0.x

Comment (by jlsantiago0):
Notice that with 4.0.2 release build you can configure the bitrate and get
different bitrate in the output. Granted the bitrate is higher than
requested. Asking for 2Mbps achieves approx 3.2Mbps and asking for 4Mbps
achieves approx 5.5Mbps
