Palette mode should only be enabled only when we know that the content of the picture is simple. For example, only white letters on black screen in SCC mode. So, by default, we need to disable it. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/7696>

|
|
* @short_description: A VA-API based AV1 video encoder
|
|
*
|
|
* vaav1enc encodes raw video VA surfaces into AV1 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 ! vaav1enc ! av1parse ! mp4mux ! filesink location=test.mp4
|
|
* ```
|
|
*
|
|
* Since: 1.22

|
* picture buffer size to avoid overflow. If the "bitrate" is not

* set, it is calculated by the picture resolution and frame
|

* rate. If "cpb-size" is not set, it is set to the size of

* caching 2 second coded data. Encoder will try its best to make
|
|
* the QP with in the ["max-qp", "min-qp"] range. "mbbrc" can
|
|
* enable bit rate control in macro block level. Other paramters
|
|
* 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
|
|
* picture buffer size to avoid overflow. If the "bitrate" is not
|
|
* set, the target bit rate will be calculated by the picture
|
|
* resolution and frame rate. Encoder will try its best to make

|
* the QP with in the ["max-qp", "min-qp"] range. "mbbrc" can

* enable bit rate control in macro block level. Other paramters
