* SECTION:element-d3d11convert
|
||||
* @title: d3d11colorconvert
|
||||
*
|
||||
* This element resizes video frames and change color space.
|
||||
* By default the element will try to negotiate to the same size on the source
|
||||
* and sinkpad so that no scaling is needed.
|
||||
* It is therefore safe to insert this element in a pipeline to
|
||||
* get more robust behaviour without any cost if no scaling is needed.
|
||||
*
|
||||
* ## Example launch line
|
||||
* |[
|
||||
* gst-launch-1.0 -v videotestsrc ! video/x-raw,format=NV12 ! d3d11upload ! d3d11convert ! d3d11videosink
|
||||
* ]|
|
||||
* This will output a test video (generated in NV12 format) in a video
|
||||
* window. If the video sink selected does not support NV12
|
||||
* d3d11colorconvert will automatically convert the video to a format understood
|
||||
* by the video sink.

|
||||
* @short_description: A Direct3D11 based color conversion and video resizing element
|
||||
*
|
||||
* This element resizes video frames and change color space.
|
||||
* By default the element will try to negotiate to the same size on the source
|
||||
* and sinkpad so that no scaling is needed.
|
||||
* It is therefore safe to insert this element in a pipeline to
|
||||
* get more robust behaviour without any cost if no scaling is needed.
|
||||
*
|
||||
* ## Example launch line
|
||||
* ```
|
||||
* gst-launch-1.0 videotestsrc ! video/x-raw,format=NV12 ! d3d11upload ! d3d11convert ! d3d11videosink
|
||||
* ```
|
||||
* This will output a test video (generated in NV12 format) in a video
|
||||
* window. If the video sink selected does not support NV12
|
||||
* d3d11convert will automatically convert the video to a format understood
|
||||
* by the video sink.
