# vadeinterlace

vadeinterlace deinterlaces interlaced video frames to progressive video frames. This element and its deinterlacing methods depend on the installed and chosen VA-API driver, but it's usually avaialble with bob (linear) method.

This element doesn't change the caps features, it only negotiates the same dowstream and upstream.

## Example launch line

    gst-launch-1.0 filesrc location=interlaced_video.mp4 ! parsebin ! vah264dec ! vadeinterlace ! vapostproc ! autovideosink

## Properties

### method

    “method” Va-deinterlace-methods *

Selects the different deinterlacing algorithms that can be used.

It depends on the driver the number of available algorithms, and they provide different quality and different processing consumption.

Flags : Read / Write

Default value : bob (1)

## Named constants

### Va-deinterlace-methods

#### Members

`bob` (1) – Bob: Interpolating missing lines by using the adjacent lines.
`adaptive` (3) – Adaptive: Interpolating missing lines by using spatial/temporal references.
`compensated` (4) – Compensation: Recreating missing lines by using motion vector.
