Webcams were among the first devices to support the UVC standard and are currently the most popular UVC devices.[citation needed]
TV receivers and video recorders[edit]
UVC v1.5 supports transmission of compressed video streams, including MPEG-2 TS, H.264, MPEG-4 SLSMPTE VC1 and MJPEG.[1]
Formats[edit]
- Uncompressed YUV formats YUY2, NV12[1]
- DV formats SD-DV, SDL-DV, and HD-DV (525-60, 625-50, 1125–60, 1250-50)[1]

Operating system support[edit]
Usb Video Device Driver X64
- Android
- As of the release of Android 10 (and still as of June 2020) Android does not support UVC [2](USB video devices). Earlier Android versions do support UVC.
- Linux
- USB video class support for Linux is provided by the Linux UVC driver, although as of July 2017 support for still-image capture is not yet implemented.[3] The UVC driver has been included in the Linux kernel source code since kernel version 2.6.26. Detection of UVC 1.5 devices was introduced in Linux kernel version 4.5,[4] but support in the driver for UVC 1.5 specific features or specific UVC 1.5 devices was not added and MPEG-2 TS, H.264 and VP8 payloads are not supported yet. The result is that some UVC 1.5 devices that also support UVC 1.1 work correctly.
- OS X
- OS X ships with a UVC driver included since version 10.4.3,[5] updated in 10.4.9 to work with iChat.[6]
- Windows
- Windows XP has a class driver for USB video class 1.0 devices since Service Pack 2, as does Windows Vista and Windows CE 6.0. A post-service pack 2 update that adds more capabilities is also available.[7] Windows 7 added UVC 1.1 support. Support for UVC 1.5 is currently only available in Windows 8 and 10.[8][9][10][11] Most device manufacturers do, however, provide their own drivers tailored to the capabilities of the product in question.[citation needed]:
