Comments
Call IltmmAnalogVideoDecoder::get_VCRHorizontalLocking to retrieve the current video source type.
The timing accuracy of synchronization pulses is typically poorer from a tape source than from a broadcast source. Setting the value to VARIANT_TRUE tells the decoder Also known as a decompressor Also known as a decoder, this is a module or algorithm to decompress data., this is a module or algorithm to decompress data. to relax its standards, which provides a better chance of maintaining sync.
