AVFilterLink (JavaCPP Presets for FFmpeg 4.4-1.5.6 API)

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

All Implemented Interfaces:

AutoCloseable
```
@Properties(inherit=avfilter.class)
public class 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.

  - frame_rate
```
@ByRef
public AVRational frame_rate()
```
    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.

```
public AVFilterLink partial_buf_size(int setter)
```
  - min_samples
```
public int min_samples()
```
    Minimum number of samples to filter at once. If filter_frame() is called with fewer samples, it will accumulate them in partial_buf. This field and the related ones must not be changed after filtering has started. If 0, all related fields are ignored.
  - min_samples
```
public AVFilterLink min_samples(int setter)
```
  - max_samples
```
public int max_samples()

    Internal structure members. The fields below this limit are internal for libavfilter's use and must in no way be accessed by applications.
