Goke IPC sandbox for enc params

Tool for changning HiSilicon/Goke encoder params.

How to Compile

Download and compile OpenIPC firmware in < OpenIPC >
Copy gkrcparams.c to <OpenIPC>/openipc-firmware/output/build/majestic-plugins-HEAD/hisilicon then
cd <OpenIPC>/openipc-firmware/output/build/majestic-plugins-HEAD
then run

<OpenIPC>/openipc-firmware/output/per-package/majestic-plugins/host/bin/arm-openipc-linux-musleabi-gcc \

Sample usage:
gkrcparams --MaxQp 30 --MaxI 2

Tested on gk7205 and h3516 majestic must running when calling the app. Changes won't persist if majestic is restarted.

Current options that can be changed --MaxI u32MaxIprop[u32MinIprop,100]
--MinI u32MinIprop[1,u32MaxIprop]
--MaxQp u32MaxQp[MinQp, 51]
--MinQp u32MinQp[0, 51]
--MaxReEnc s32MaxReEncodeTimes[0, 3]
--MaxQpD u32MaxQpDelta[0, 4]
--RefreshNum u32RefreshNum (enables IntraRefresh)

• u32MaxIprop Maximum ratio of bits allocated to the I-frames and P-frames Value range: [u32MinIprop,100] Default value: 100

-u32MaxQp Maximum QP value of the P-frame and B-frame Value range: [MinQp, 51] Default value: 51

-u32MinQp Minimum QP value of the P-frame and B-frame Value range: [0, 51] Default value: 16

• s32MaxReEncodeTimes Number of times that each frame is re-encoded. The value 0 indicates that the frame is not re-encoded. Value range: [0, 3] Default value: 2

− u32MaxQpDelta Indicates the difference between the maximum QP value of the frame level and the maximum QP value of the CU level. This is an advanced CVBR parameter. When the image content is complex, the bit rate control increases the QP value. When the frame-level QP value is adjusted to the maximum, the bit rate control does not increase the frame-level QP value. However, the CU/MB-level bit rate control still takes effect, and the QP value in the strong texture area of the image can be increased.
