These parameters are not documented yet, please consult with the cmake/OpenCVDetectCUDA.cmake script for details. Additional options can be used to control build process, e.g. For cmake versions older than 3.9 OpenCV uses own cmake/FindCUDA.cmake script, for newer versions - the one packaged with CMake. CUDA toolkit must be installed from the official NVIDIA site as a prerequisite. Many algorithms have been implemented using CUDA acceleration, these functions are located in separate modules. If BUILD_ option is disabled, 3rdparty library will be detected and enabled if found => HAVE_ set to ON if dependency is found.If BUILD_ option is enabled, 3rdparty library will be built and enabled => HAVE_ set to ON.Options starting with HAVE_ indicate that dependency have been enabled, can be used to manually enable a dependency if automatic detection can not be used.Options starting with BUILD_ enable or disable building and using 3rdparty library bundled with OpenCV.Options starting with WITH_ enable or disable a dependency.There are three kinds of options used to control dependencies of the library, they have different prefixes: cmake has special option allowing to print all available configuration parameters:Ĭmake -LH. There are many optional dependencies and features that can be turned on or off.

Cisco has taken our H.264 implementation, and open sourced it under BSD license terms. OpenH264 is designed to be used in applications that require encoding and decoding video in real time, such as WebRTC. In October 2014, Mozilla launched Firefox 33, the first major release to support OpenH264.

Support in Firefox Īlso on the day of Cisco's free-use announcement, October 30, 2013, Brendan Eich from Mozilla wrote that it would use Cisco's binaries in future versions of Firefox to add support for H.264 to Firefox where platform codecs are not available.

Ĭisco published the source code of OpenH264 on December 9, 2013. The announced reason was that they needed to separate it from dependencies on other Cisco code that is not intended to be open-sourced, confirm that it does not have any 0-day security vulnerabilities that could jeopardize other Cisco products using the same code, and make sure all necessary legal processes are completed. Īlthough the source code for OpenH264 already existed in October 2013 and was used internally by Cisco products, Cisco did not publish its OpenH264 codec immediately.

On October 30, 2013, Rowan Trollope from Cisco Systems announced that Cisco would release both binaries and source code of an H.264 video codec called OpenH264 under the Simplified BSD license, and pay all royalties for its use to MPEG LA themselves for any software projects that use Cisco's precompiled binaries (thus making Cisco's OpenH264 binaries free to use) any software projects that use Cisco's source code instead of its binaries would be legally responsible for paying all royalties to MPEG LA themselves, however.Ĭurrent target CPU architectures are x86 and ARM, and current target operating systems are Linux, Windows XP and later, Mac OS X, and Android iOS is notably absent from this list because it doesn't allow applications to fetch and install binary modules from the Internet. It is released under the terms of the Simplified BSD License. OpenH264 is a free software library for real-time encoding and decoding video streams in the H.264/MPEG-4 AVC format.
