org.bytedeco.javacpp.avfilter.AVFilterLink

All Implemented Interfaces:

AutoCloseable

Enclosing class:

avfilter

public static class avfilter.AVFilterLink
extends Pointer

A link between two filters. This contains pointers to the source and destination filters between which this link exists, and the indexes of the pads involved. In addition, this link also contains the parameters which have been negotiated and agreed upon between the filter, such as image dimensions, format, etc. Applications must not normally access the link structure directly. Use the buffersrc and buffersink API instead. In the future, access to the header may be reserved for filters implementation.

@ByRef

Frame rate of the stream on the link, or 1/0 if unknown or variable; if left to 0/0, will be automatically copied from the first input of the source filter if it exists. Sources should set it to the best estimation of the real frame rate. If the source frame rate is unknown or variable, set this to 1/0. Filters should update it if necessary depending on their function. Sinks can use it to set a default output frame rate. It is similar to the r_frame_rate field in AVStream.
