Detailed Description

Instance of channel templates allocated and set by the host.

A channel is an actual implementation of a channel template (livido_channel_template) hold by the filter (livido_instance) and setup by the host to prepare for initialization (::livido_init).

If a channel template is optional (LIVIDO_CHANNEL_OPTIONAL flag), the host can indicate whether is being used or not by setting the flag LIVIDO_CHANNEL_DISABLED in this structure.

Field Documentation

int livido_channel::rowstrides[4]

length of one row in bytes (include padding) In packed modes rowstride[0] is the length of the row in bytes (including padding bytes) In planar modes every rowstride denotes the length of the plane in bytes! IMPORTANT: Every host has to set the rowstrides and every plugin has to honour the rowstrides. Definition at line 1069 of file livido.h.
