java.lang.Object
- org.bytedeco.javacpp.Pointer
- - org.bytedeco.javacpp.avfilter.AVFilterLink

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.

```
    Frame rate of the stream on the link, or 1/0 if unknown; if left to 0/0, will be automatically be 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. 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.

```

```
public avfilter.AVFilterLink min_samples(int min_samples)
```
  - max_samples
```
public int max_samples()

```
  - cur_buf_copy
```
public avfilter.AVFilterBufferRef cur_buf_copy()
```
    The buffer reference currently being received across the link by the destination filter. This is used internally by the filter system to allow automatic copying of buffers which do not have sufficient permissions for the destination. This should not be accessed directly by the filters.
  - cur_buf_copy
```
public avfilter.AVFilterLink cur_buf_copy(avfilter.AVFilterBufferRef cur_buf_copy)
```
  - closed
```
public int closed()
```
    True if the link is closed. If set, all attempts of start_frame, filter_frame or request_frame will fail with AVERROR_EOF, and if necessary the reference will be destroyed. If request_frame returns AVERROR_EOF, this flag is set on the corresponding link. It can be set also be set by either the source or the destination filter.
  - closed
```
public avfilter.AVFilterLink closed(int closed)
```
  - channels
```
public int channels()
```
    Number of channels.

```
@Cast(value="unsigned")
public int flags()
