* @title: vah265enc
|
|
* @short_description: A VA-API based H265 video encoder
|
|
*
|
|
* vah265enc encodes raw video VA surfaces into H.265 bitstreams using
|
|
* the installed and chosen [VA-API](https://01.org/linuxmedia/vaapi)
|
|
* driver.
|
|
*
|
|
* The raw video frames in main memory can be imported into VA surfaces.
|
|
*
|
|
* ## Example launch line
|
|
* ```
|
|
* gst-launch-1.0 videotestsrc num-buffers=60 ! timeoverlay ! vah265enc ! h265parse ! mp4mux ! filesink location=test.mp4
|
|
* ```
|
|
*
|
|
* Since: 1.22

* are ignored.

* 3. VBR mode: "rate-control=VBR", then the "bitrate" specify the
|
|
* target bit rate, "target-percentage" is used to calculate the
|
|
* max bit rate of VBR mode by ("bitrate" * 100) /
|
|
* "target-percentage". It is also used by driver to calculate
|
|
* the min bit rate. The "cpb-size" specifies the max coded

* resolution and frame rate. Encoder will try its best to make
