[Bug] Webcam stream fails on Dell Precision 5480 with "Link has been severed" error #382
Description
Hello,
The webcam on my Dell Precision 5480 is not working on Linux Mint 21.3. After successfully compiling and installing the latest drivers from the main branch, the kernel modules load and the /dev/video* device nodes are created. However, attempting to stream from the device fails.
Hardware Information:
- Laptop: Dell Precision 5480 (2023)
- OS: Linux Mint 21.3 Cinnamon
- Kernel: 6.8.0-65-generic
- Camera Sensor (from dmesg): OVTI01A0:00 (OmniVision OV01A10)
Symptoms:
- Cheese and Guvcview show a black screen with a "There was an error playing video from the webcam" type of error.
- The user is correctly in the 'video' group.
Key Diagnostic Output:
When running v4l2-ctl --device /dev/video0 --stream-mmap --stream-count=1 --stream-to=test.raw, I get the following error:
VIDIOC_STREAMON returned -1 (Link has been severed)
The output of v4l2-ctl --list-formats-ext is:
