Windows 10 x64, Python 3.10.6 x64, pyuvc v 1.0: Can't open stream control - error: 'Operation not supported' #100
Description
Windows 10 x64
Python 3.10.6 x64 (thonny-4.0.1-windows-portable)
pyuvc v 1.0
libusbK-3.0.7.0-setup(same issue with libusbK-3.1.0.0-setup)
Followed instructions from here:
https://github.com/pupil-labs/pyuvc/blob/master/WINDOWS_USER.md
and installed pupil-labs-uvc, is there something else to do?
(and https://int80k.com/libuvc/ does not work for me: The connection has timed out)
code from examples:
import uvc
devices = uvc.device_list()
print("Available devices", devices)
for device in devices:
try:
cap = uvc.Capture(device["uid"])
except uvc.DeviceNotFoundError:
continue
print(f"{cap.name}")
print("Available modes:")
for mode in cap.available_modes:
print(
f"MODE: {mode.width} x {mode.height} @ {mode.fps} ({mode.format_name})"
)
print("Iterating over frame sizes and rates")
for res in cap.frame_sizes:
cap.frame_size = res
for rate in cap.frame_rates:
cap.frame_rate = rate
print(f"RES/RATE: {res[0]} x {res[1]} @ {rate} Hz")
cap.close()
output:
Available devices [{'name': 'RYS HFR USB2.0 Camera', 'manufacturer': 'RYS HFR USB2.0 Camera', 'serialNumber': 'unknown', 'idProduct': 5461, 'idVendor': 5546, 'device_address': 9, 'bus_number': 1, 'uid': '1:9'}]
