Enables low-latency mode in a codec.
Data typeULONG (VT_BOOL)
If the value is nonzero, low-latency mode is enabled. If the value is zero, low-latency mode is disabled.
This property applies to both encoders and decoders.
Low-latency mode is useful for real-time communications or live capture, when latency should be minimized. However, low-latency mode might also reduce the decoding or encoding quality.
The encoder is expected to not add any sample delay due to frame reordering in encoding process, and one input sample shall produce one output sample. B slices/frames can be present as long as they do not introduce any frame re-ordering in the encoder.
