* @title: vadeinterlace
|
|
* @short_description: A VA-API base video deinterlace filter
|
|
*
|
|
* vadeinterlace deinterlaces interlaced video frames to progressive
|
|
* video frames. This element and its deinterlacing methods depend on
|
|
* the installed and chosen [VA-API](https://01.org/linuxmedia/vaapi)
|
|
* 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
|
|
* ```
|
|
*
|
|
* Since: 1.20
|
