muzhi 说:One more question, have you tried using the -n, -t or -d options in yavta to adjust the number of video buffers, the delay before requeuing buffers and the time per frame?
do you live in China? Can I have any number (whatsapp, wechat, telegram, ...) from you?
thanks
yes,I live in china

In another post, I noticed that you are looking for available images, actually, there are many discussions related to V3s Cam here, maybe you can refer to:

Some of these discussions also provide image files, these discussions use mjpg-streamer and ffmpeg and fswebcam as test tools, maybe you can try it.
urb 错误通常与usb有关,我搜索了Google看起来已经有许多工程师遇到这样同样的报错,看起来该错误是由于USB带宽不足或速率太慢,但大家并没有讨论出可靠的解决方案。供您参考 : https://lore.kernel.org/linux-usb/CAJ+vNU194rZZRjQxSjN6OXXWBEgniHcO1=g==rPwcumKqhh1hA@mail.gmail.com/
The urb error is usually related to usb. I searched Google and it seems that many engineers have encountered the same error. It seems that the error is due to insufficient USB bandwidth or too slow speed, but no reliable solution has been discussed.

One more question, do you have dma enabled in UVC?
多年以后,有一位萌新吭哧吭哧的顺着搜索引擎又翻出来这篇帖子,我的版本号更激进,不过这个报错的确好奇怪,glibc选择5.10.x,kernel版本5.10.3
搜索引擎找到几篇文章,linux kernel 报错:FATAL: kernel too old -CSDN
FATAL: kernel too old -CSDN
按上述文章指导,file指令查看交叉编译时生成的libc,可以看到确实目标kernel版本号确实要高。"nterpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 5.15.0"
除了一些IDE/编译器自带的源码阅读功能外,个人现在用的专业阅读代码的就source insght 和opengrok了吧,大项目还是opengrok方便。 https://androidbsp.com/ 之前网上找opengrok发现的一个站,不清楚谁做的查了下备案应该是个人,但这一套系统和公司里的一样 公司都没他专业
