libuvc is a cross-platform library for USB video devices, built atop libusb.
It enables fine-grained control over USB video devices exporting the standard USB Video Class
(UVC) interface, enabling developers to write drivers for previously unsupported devices,
or just access UVC devices in a generic fashion.
Getting and Building libuvc
Prerequisites: You will need libusb and CMake installed.
To build, you can just run these shell commands:
git clone https://github.com/ktossell/libuvc
cd libuvc
mkdir build
cd build
cmake ..
make && sudo make install
and you’re set! If you want to change the build configuration, you can edit CMakeCache.txt
in the build directory, or use a CMake GUI to make the desired changes.
Developing with libuvc
The documentation for libuvc can currently be found at https://int80k.com/libuvc/doc/.
Happy hacking!
CHANGELOG
Changes in 0.0.5 (2014-07-19)
----------------
New features:
- Added support for all of the camera terminal and processing unit controls, including the controls
that appeared in UVC 1.1 and 1.5.
- Added LIBUVC_VERSION_GTE(major, minor, patch) macro.
Bug fixes:
- Switching to explicit kernel driver detachment since auto_detach isn't available in libusb < 1.0.16.
- The cmake module now looks for libuvc.dylib instead of libuvc.so on OS X.
Changes in 0.0.4 (2014-06-26)
----------------
New features:
- Support devices with multiple streaming interfaces and multiple concurrent streams.
A new uvc_stream* API is added, along with a uvc_stream_handle type to encapsulate the
state of a single UVC stream. Multiple streams can run alongside each other, provided
your USB connection has enough bandwidth. Streams can be individually stopped and
resumed; the old uvc_start/stop_streaming API is still provided as a convenient way
to interact with the usual one-stream devices.
- Added support for MJPEG streams.
- Added functions for checking/setting autofocus mode.
- Added an interface to set/get arbitrary controls on units and terminals.
- Made the input, output, processing and extension units public.
- Implemented uvc_get_device and uvc_get_libusb_handle.
- Add a library-owned flag to uvc_frame_t so that users may allocate their own frame buffers.
Bug fixes:
- Send frames as soon as they're received, not when the following frame arrives
- Fixed call to NULL when no status callback is provided.
- Fixed crash that occurred during shutdown if the USB device was disconnected during streaming.
Miscellaneous improvements:
- Hid the transfer method (isochronous vs bulk) from the user. This was never really
selectable; the camera's streaming interface supports either bulk or isochronous
transfers, so now libuvc will figure out which one is appropriate. The `isochronous`
parameter has been converted to a `flags` parameter, which is currently unused but
could be used to convey up to 7 bits of stream mode information in the future.
- Improved the method for claiming the camera's interfaces.
- Renamed UVC_COLOR_FORMAT_* to UVC_FRAME_FORMAT_*. The old #defines are still available.
- Simplified format definition and lookup.
- Improved transfer status (error) handling.
