MTP or (Media Transfer Protocol) is a set of custom extensions to the Picture Transfer Protocol (PTP) devised by Microsoft, to allow the protocol to be used for devices other than digital cameras, for example digital audio players such as MP3 players, and other portable media devices, for example portable video players.

The USB video device class (also USB video class or UVC) is a USBdevice class that describes devices capable of streaming video like webcams, digital camcorders, transcoders, analog video converters and still-image cameras.

• Hi, I was advised by a Dell technician a while ago that it is recommended to download the latest device drivers from the Dell Support site to a USB stick before doing a clean installation of Windows 8.1. Should I download the drivers to my hard drive (c: drive) and then copy and paste them over to the USB flash drive.
• . Closed thread: On a certain audio device that wasn't working in their Device Manager under their Universal Serial Bus Controllers - it reads:.Unknown USB Device (Device Descriptor Request Failed). So they were told the 2nd option to fix this problem is: M ethod 2: Disable and re-enable all the Universal Serial Bus controllers (USB) controllers.

The latest revision of the USB video class specification carries the version number 1.5 and was defined by the USB Implementers Forum in a set of documents describing both the basic protocol and the different payload formats.^[1]

Devices[edit]

Webcams[edit]

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]
• Frame-based^[1]
• Video stream formats like MPEG-2 TS, H.264, MPEG-4 SL, SMPTE VC1, VP8 and MJPEG^[1]

For detailed history on releases, see the revision history section of the published USB UVC documents, available from the USB.org page.

Operating system support[edit]

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]}:

FreeBSD

FreeBSD added the uvc driver for UVC devices in Jan 18, 2011; added in the 9.0 release.^[12]

NetBSD

NetBSD added the uvideo driver for UVC devices in September 2008; added in the 5.0 release.^[13]

OpenBSD

OpenBSD added the uvideo driver for UVC devices in April 2008; it appears in the 4.4 release.^[14]

PlayStation 3

The PlayStation 3 added support for UVC compatible webcams in firmware version 1.54 (only works for video chat, not games.)

MenuetOS

MenuetOS added support for UVC compatible webcams in version 0.87

Solaris

Solaris includes support for UVC webcams in the form of the usbvc driver for OpenSolaris. The driver ships with Solaris Express build 56 and later.^[15]
