Hi  

在imx8qm mek 上按照下面的指导移植nvp6324 驱动,驱动是可以工作的。但是发现其他一些问题:

Nvp6324 driver for imx8qm. 

    但是使用使用下面的命令,命令在/unit_tests/V4L2_VPU 文件夹下,得到的h264 视频数据 p slice   (数据开头应该是是00 00 00 01 41 .......)实际上会在41 前面多出13个数据,例如下面颜色mark 部分。

0 0 0 1 6 1 7 0 0 12 0 0 3 2 4 5 10 41 6d 70 68 69 6f 6e 20 53 65 6d 69 0 

./mxc_v4l2_vpu_enc.out camera --key 0 --device /dev/video1 --size 1280 720 --fmt nv12 --framerate 30 \
encoder --key 1 --source 0 --size 1280 720 --framerate 30 \
encoder --key 2 --source 0 --size 640 360 --framerate 30 \
ofile --key 4 --source 1 --name camera_1.h264 \
ofile --key 5 --source 2 --name camera_2.h264

请教这部分数据是什么? 应该如何把这部分在vpu 压缩过程中去除? 谢谢!

Hi Wang,

I’m afraid that i.MX8QM family is still on preproduction and no additional information/support could be provided yet.

For further assistance, please contact with your Sales/FAE.


Hope this will be useful for you.
Best regards!
/Carlos
