1. The PTS of all frames should not be changed. 2. Just update the DTS based on the PTS. For the frame which is not reordered, the DTS is equal to PTS. For frame which is reordered, the DTS is equal to previous DTS. For example: Input: F0[D0, P0] -- F1[D1, P1] -- F2[D2, P2] -- F3[D3, P3] Output: F0[I, D0, P0] -- F3[P, D0, P3] -- F1[B, D1, P1] -- F2[B, D2, P2] Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/6703>

* @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

|
* "max-qp", "min-qp", "qpi", "qpp", "qpb", "mbbrc", "cpb-size",
|
|
* "rate-control" and "target-usage" to control the RC behavior.
|
|
*
|
|
* "target-usage" is different from the others, it controls the encoding
|
|
* speed and quality, while the others control encoding bit rate and
|
|
* quality. The lower value has better quality(maybe bigger MV search
|
|
* range) but slower speed, the higher value has faster speed but lower
|
|
* quality. It is valid for all modes.
|
|
*
|
|
* The possible composition to control the bit rate and quality:
|
|
*
|
|
* 1. CQP mode: "rate-control=cqp", then "qpi", "qpp" and "qpb"
|
|
* specify the QP of I/P/B frames respectively(within the
|
|
* "max-qp" and "min-qp" range). The QP will not change during
|
|
* the whole stream. Other properties are ignored.
|
|
*
|
|
* 2. CBR mode: "rate-control=CBR", then the "bitrate" specify the
|
|
* target bit rate and the "cpb-size" specifies the max coded
|
|
* 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
|
|
* are ignored.
|
|
*
|
|
* 4. VCM mode: "rate-control=VCM", then the "bitrate" specify the
|
|
* target bit rate, and encoder will try its best to make the QP
|
|
* with in the ["max-qp", "min-qp"] range. Other paramters are
|
|
* ignored.
|
|
*
|
|
* 5. ICQ mode: "rate-control=ICQ", which is similar to CQP mode
|
|
* except that its QP may be increased or decreaed to avoid huge
|
|
* bit rate fluctuation. The "qpi" specifies a quality factor
|
|
* as the base quality value. Other properties are ignored.
|
|
*
|
|
* 6. QVBR mode: "rate-control=QVBR", which is similar to VBR mode
|
|
* with the same usage of "bitrate", "target-percentage" and
|
|
* "cpb-size" properties. Besides that, the "qpi" specifies a
|
|
* quality factor as the base quality value which the driver
|
|
* should try its best to meet. Other properties are ignored.
