select nvp6324 to y in menuconfig(default is 'y')Hi Bert,
这个驱动是可以工作的。
但是使用使用下面的命令,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,
We may neet to use the Imx8M Mini EVK with NVP6324. I guess you mean the same processor with "imx8mq", right?
Do we really need virtual channel for just one NVP6324 IC? I mean we only want to connect 4 AHD cam to NVP then MIPI CSI2 port of IMX8M mini.
By the way, if you look at the reference manual of IMX8M mini page 4046, there is register to check the virtual ID, so there may a way to connect in your case.
Cheers,
Umit
