## Detailed Description

Deinterlacer.

Deinterlacing is supported either through the gavl_video_converter_t or using a low level deinterlacer

## Typedef Documentation

typedef struct gavl_video_deinterlacer_s gavl_video_deinterlacer_t

Opaque deinterlacer structure.

You don't want to know what's inside.

## Function Documentation

gavl_video_deinterlacer_t* gavl_video_deinterlacer_create | ( |  | ) |

Create a video deinterlacer.

Returns:
  A newly allocated video deinterlacer

void gavl_video_deinterlacer_destroy | ( | gavl_video_deinterlacer_t * | deinterlacer | ) |

Destroy a video deinterlacer.

Parameters:

  | deinterlacer | A video deinterlacer

gavl_video_options_t* gavl_video_deinterlacer_get_options | ( | gavl_video_deinterlacer_t * | deinterlacer | ) |

gets options of a deinterlacer

Parameters:

  | deinterlacer | A video deinterlacer

After you called this, you can use the gavl_video_options_set_*() functions to change the options. Options will become valid with the next call to gavl_video_deinterlacer_init

int gavl_video_deinterlacer_init | ( | gavl_video_deinterlacer_t * | deinterlacer,
|  | const gavl_video_format_t * | src_format |
| ) |  |  |

Initialize a video deinterlacer.

Parameters:

  | deinterlacer | A video deinterlacer
  | src_format | Input format

Returns:
  If something goes wrong (should never happen), -1 is returned.

You should have equal pixelformats in the source and destination. This function can be called multiple times with one instance.

void gavl_video_deinterlacer_deinterlace | ( | gavl_video_deinterlacer_t * | deinterlacer,
|  | const gavl_video_frame_t * | input_frame,
|  | gavl_video_frame_t * | output_frame |
| ) |  |  |

Deinterlace video.

Parameters:

  | deinterlacer | A video deinterlacer
  | input_frame | Input frame
  | output_frame | Output frame
