@murraytodd that's okay.

@jugg 还可以参考下图方法直接dump出buffer

@bg8wj
更新到新镜像或使用新内核编译替换

@edwardzhou : good

@george
yuv i420那个有办法吗
videoconvert
mppjpegdec
好像都不支持从nv12转i420

@AugustRobot_Zou 👍 👍

@edwardzhou 默认video11

@jack_admin 原來是這樣 ... 哈哈！

@jack_admin
我用 gnome-session-properties 添加了，謝謝

@jack_admin

可以使用，感谢。
的确关掉效果没有绑定大核好。

@ccjjww1222 V11版本是板载天线。V10是外置天线，你的是哪个版本

@大法师 是权限问题，修改/media/coolpi文件夹的用户为coolpi就可以了

@george 试了不能用

可以通过了，就因为文件路径存在空格

@jack_admin 👍

@george
gstramer的硬件解码插件叫什么 只有openh264dec ?

@george
上面那个命令末尾添加sync=false 就正常了

@大法师 Hi again, can you please check in a basic README to that fedora repo? I am not able to fork it because there are no commits.

@sushruth The 6. x kernel version has been processed internally and is expected to be released in the second quarter.Thank you for your support.

the good news is that the 20230303 download has solved the pip3 install problem and i was able to install opencv as well. It is running on a usb stick at the moment. should this issue be closed?

2)the format commands are not working as shown:

ubuntu@coolpi:~$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
sda 8:0 1 0B 0 disk
sdb 8:16 1 0B 0 disk
mmcblk0 179:0 0 58.2G 0 disk

mmcblk0boot0 179:32 0 4M 1 disk
mmcblk0boot1 179:64 0 4M 1 disk
zram0 254:0 0 0B 0 disk

the tf chip is sda and sdb upon insertion via a usb adapter. the coolpi does not recognized the chip via the onboard tf card slot.

ubuntu@coolpi:~$ sudo wipefs /dev/sda

@jugg 这个建议不错，需要做这类的参考文档

最后换了阿里云的源 已经可以更新了

@allen
示例操作更改标识
sudo e2label /dev/mmcblk0p2 emmc-rootfs

@george 有这样的文档已经很不错了 感谢

@george 好的，不过能稍微再具体点嘛，或者有相关的帖子嘛

@大法师 对，更新了之后也没变化，无法运行指运行相机相关程序时会报USB uvc相关的错误。
