编译SDK提供的sample_snap例子,并放到板子上运行,预览、抓拍和视频编码都是正常的(双pipe模式)。但是调用HI_MPI_VPSS_GetChnFrame(vpssGrp1, vpssChn0),返回值是0xA007800E(图像队列为空)。
视频编码通道绑定的也是vpssGrp1, vpssChn0,编码是正常的。为什么调用上面的HI_MPI_VPSS_GetChnFrame就获取不了数据呢?

单pipe模式可以么???我试了下有问题啊
/nfsroot/nfsroot/hi3519v101 # ./sample_snap 0
MipiDev 0,WDRMode 0,ViMode = 42
set mipi phy attr successful!
s32ChnNum = 1
min=0x100,max=0x800,shift=8
linear mode
min=0x100,max=0x800,shift=8
