The KSNODETYPE_PROLOGIC_DECODER node represents a Dolby Surround Pro Logic decoder. The decoder control has one stereo input stream and one output stream with one to four channels. In the four-channel output format, the channels are mapped to left, right, center, and back speaker. In the three-channel output format, the channels are mapped to left, right, and back speakers.
The functionality of the KSNODETYPE_PROLOGIC_DECODER node is complementary to the KSNODETYPE_PROLOGIC_ENCODER node, which converts a four-channel input stream to a surround-encoded stereo output stream.
A KSNODETYPE_PROLOGIC_DECODER node should support the following required properties:
The KSPROPERTY_AUDIO_CHANNEL_CONFIG property sets and gets the channel configuration of the node's output stream.
