The idea of this change is to add, in the future, process_with_generator(), when multiple input surfaces are processed, for blending. Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/2431>

|
|
* @short_description: A VA-API base video postprocessing filter
|
|
*
|
|
* vapostproc applies different video filters to VA surfaces. These
|
|
* filters vary depending on the installed and chosen
|
|
* [VA-API](https://01.org/linuxmedia/vaapi) driver, but usually
|
|
* resizing and color conversion are available.
|
|
*
|
|
* The generated surfaces can be mapped onto main memory as video
|
|
* frames.
|
|
*
|
|
* Use gst-inspect-1.0 to introspect the available capabilities of the
|
|
* driver's post-processor entry point.
|
|
*
|
|
* ## Example launch line
|
|
* ```
|
|
* gst-launch-1.0 videotestsrc ! "video/x-raw,format=(string)NV12" ! vapostproc ! autovideosink
|
|
* ```
|
|
*
|
|
* Cropping is supported via buffers' crop meta. It's only done if the
|
|
* postproccessor is not in passthrough mode or if downstream doesn't
|
|
* support the crop meta API.
|
|
*
|
|
* ### Cropping example
|
|
* ```
|
|
* gst-launch-1.0 videotestsrc ! "video/x-raw,format=(string)NV12" ! videocrop bottom=50 left=100 ! vapostproc ! autovideosink
|
|
* ```
|
|
*
|
|
* If the VA driver support color balance filter, with controls such
|
|
* as hue, brightness, contrast, etc., those controls are exposed both
|
|
* as element properties and through the #GstColorBalance interface.
|
|
*
|
|
* Since: 1.20
