Decoding buffer size management

When RTMP stream is published from software encoder supportin hardware acceleration on NVIDIA GPU, and contains B-frames, the stream picture can twitch in some RTMP or HLS players. To workaround this, since build 5.2.863 the parameter was added to set the maximum decoding buffer size passed in SPS

h264_sps_max_dec_frame_buffering=-1

By default, buffer size is not limited. This eliminates picture twitching, but can inscrease latency due to excessive buffering. In this case, the buffer size can be limited to 2 frames (default value before build 5.2.863)

h264_sps_max_dec_frame_buffering=2

or more frames to eliminate twitching without viewable latency.
