你好,我用了 https://github.com/Kevincoooool/KS_V3S 里面的 u-boot-sunxi-with-spl.bin, zImage, sun8i-v3s-licheepi-zero-dock.dtb,并将 ksdiy.config 放在 buildroot-2017.08 里改名为 .config 后编译了文件系统。将这些东西烧入 tf 卡后,启动,执行 fswebcam 报错如下:
--- Opening /dev/video0...
Trying source module v4l2...
/dev/video0 opened.
No input was specified, using the first.
Error starting stream.
VIDIOC_STREAMON: Invalid argument
Unable to use mmap. Using read instead.
Unable to use read.
请问这是该怎么解决呢?我尝试了 fswebcam 的如下几种参数,依旧如此:
fswebcam -d /dev/video0 --no-banner -r 320x240 capture.jpg
fswebcam -S 1 -d /dev/video0 -p UYVY -r 1600x1200 test.jpg
fswebcam --no-banner -r 640x480 image.jpg
