Hi NV，
1，Using V4L2 API
2，1/30 probability, unable to get camera video stream
Stress test case:
step1: Open camera video stream
step2: Soft restart the system
step1 - step2
trace.log (47.1 MB)
28times_dmesg_dualOLC009_greenerror.log (77.2 KB)
. . .
Please help analyze or provide some debugging methods, thank you!
The error tell the PD CRC error. I would suspect could be the sensor output signal problem.
Thanks
Maybe try this patch.

Hi ShaneCCC,
I’ll test it after applying the patch, thank you!
Hi ShaneCCC,
Applied the patch you provided,

Hi ShaneCCC,

Hi future.wang,
Could you provide more information about your setup? What sensor are you using, what is your device tree configuration, format and resolution?
In the trace you shared there are several CHANSEL_NOMATCH errors. You can refer to this post for more information on how to interpret them, but they usually indicate a mismatch between the incoming and the expected resolution or format.
Hi carolina，
==Loop operation ：
1，Using V4L2 API Open camera video stream（ioctl(camera_ctx.fd, VIDIOC_DQBUF, &bufferinfo）,
and displayed via OpenCV API
2，reboot system

”they usually indicate a mismatch between the incoming and the expected resolution or format.“
==If the resolution or format does not match, it should be impossible to obtain the video stream.
