Structure that defines an input or output channel
See below.
This structure defines an instance of an input or output channel returned from a call to an addon's MediaInput->AcquireInputChannel() or MediaOutput->AcquireOutputChannel() function.
Filters are connected using these channels; an output channel is connected to an input channel. Each channel is stored as a MmChannel_t structure, whose first element is a MmElement_t structure, which provides easy identification.
This structure has at least the following members:
Neutrino
MmAcquireInputChannel(), MmAcquireOutputChannel(), MmAttachChannels(), MmFindChannelsFilter(), MmReleaseChannel(), MediaInput, MediaOutput
