FWIW, camera format support in video(1) is a bit limited, ffplay (and vlc) are able to handle other formats which may be needed by some cameras. -- Please keep replies on the mailing list.

Webcam support on Lenovo Thinkpad T14 Gen3 (Intel)
Hello, I've tried to used the integrated webcam on my brand new Thinkpad T14 on OpenBSD 7.3 without success. I've followed the FAQ. The webcam seems well detected but no image is displayed... This is what I get: # uname -a OpenBSD hyperion.my.domain 7.3 GENERIC#1072 amd64 # usbdevs -v Controller /dev/usb0: addr 01: 8086: Intel, xHCI root hub super speed, self powered, config 1, rev 1.00 driver: uhub0 addr 02: 2109:0817 VIA Labs, Inc., USB3.0 Hub super speed, self powered, config 1, rev 6.23, iSerial 0 driver: uhub2 addr 03: 0bda:0411 Generic, USB3.2 Hub super speed, self powered, config 1, rev 39.20 driver: uhub3 addr 04: 152d:0578 JMicron, USB to ATA/ATAPI Bridge super speed, power 224 mA, config 1, rev 2.14, iSerial 0123456789ABCDEF driver: umass0 addr 05: 0bda:8153 Realtek, USB 10/100/1000 LAN super speed, power 72 mA, config 1, rev 30.00, iSerial 01 driver: ure0 Controller /dev/usb1: addr 01: 8086: Intel, xHCI root hub super speed, self powered, config 1, rev 1.00 driver: uhub1 addr 02: 27c6:6594 Goodix Technology Co., Ltd., Goodix USB2.0 MISC full speed, power 100 mA, config 1, rev 1.00, iSerial UIDE2B30F1D__MOC_B0 driver: ugen0 addr 03: 04f2:b74f Chicony Electronics Co.,Ltd., Integrated Camera high speed, power 500 mA, config 1, rev 54.20, iSerial 0001 driver: uvideo0 driver: uvideo1 driver: ugen1 addr 04: 2109:2817 VIA Labs, Inc., USB2.0 Hub high speed, self powered, config 1, rev 6.23, iSerial 0 driver: uhub4 addr 05: 1a40:0801 Terminus Technology, USB 2.0 Hub high speed, self powered, config 1, rev 1.00 driver: uhub5 addr 06: 03f0:1a4a Lite-On Technology Corp., HP Wireless Slim Keyboard - Skylab EU full speed, power 100 mA, config 1, rev 0.66 driver: uhidev0 driver: uhidev1 driver: uhidev2 addr 07: 19f7:0015 R\M-XDE Microphones, R\M-XDE NT-USB Mini full speed, power 100 mA, config 1, rev 1.18, iSerial 45803936 driver: uaudio0 driver: uhidev3 addr 08: 0bda:5411 Generic, USB2.1 Hub high speed, self powered, config 1, rev 39.20 driver: uhub6 addr 09: 0bda:1100 Realtek, HID Device high speed, self powered, config 1, rev 1.01 driver: uhidev4 addr 10: 2109:8884 VIA Labs, Inc., USB Billboard Device high speed, self powered, config 1, rev 0.01, iSerial 0001 driver: ugen2 addr 11: 8087:0033 Intel, Bluetooth full speed, self powered, config 1, rev 0.00 driver: ugen3 # sysctl kern.video.record kern.video.record=1 # dmesg | grep "uvideo" uvideo0 at uhub1 port 4 configuration 1 interface 0 "Chicony Electronics Co.,Ltd.
