Platforms

• Windows 10
• Android API 21

Requirements

• CMake 3.16.0
• Conan 1.56.0
• Visual Studio 2019 (Windows only)
• Linux (Cross build Linux to Android)

Windows build

Before build libvideo on Windows

On main project directory execute:
debug version

py .ci/prebuild_thirdparty.py --build-debug

release version

py .ci/prebuild_thirdparty.py --build-release

Build via Visual Studio

cmake -S . -B build_ -G "Visual Studio 16 2019"
MSBuild /fl /flp:Verbosity=diagnostic /t:Build /p:Configuration=Debug /nologo /m:4 libvideo.sln

Use -pr=.ci/conan_profiles/conan_profile_release if you want build release version

Build via Conan

conan build . --build-folder build_

Deployment Windows

conan create . libvideo/1.0.0@ccor/libvideo --build=missing

Deployment Linux (Cross build Linux to Android)

conan create . libvideo/1.0.0@ccor/libvideo -tf None --build=missing

Android build (cross-build from Linux)

Before build libvideo on Linux

On main project directory execute:
debug version

python3 .ci/prebuild_thirdparty.py --build-debug --android

release version

python3 .ci/prebuild_thirdparty.py --build-release --android

Build via Android Studio

1. Open libvideo-android folder as Android Studio project
2. Use Android Studio to build project

Build via Gradle

In AndroidSDK folder

./gradlew build

Hardware acceleration

Hardware encoding through AMD AMF (Version 1.4.26)

1. Go to AMF SDK github and download project files

2. Create folder "ForAMF", inside this folder create folder "AMF"

3. Download AMF SDK

4. Copy folders "components" and "core" from downloaded "amf/public/include" to "AMF" folder

   The path should be like this:

   C:/ForAMF/AMF/components
   C:/ForAMF/AMF/core
   

5. On main project directory execute:
   debug version

   py .ci/prebuild_thirdparty.py --build-debug --enable-amf -cflags <path_to_AMF>
   

   release version

   py .ci/prebuild_thirdparty.py --build-release --enable-amf -cflags <path_to_AMF>
   

   For example:

   py .ci/prebuild_thirdparty.py --build-release --enable-amf -cflags C:/ForAMF/
   

Formatting and code style

C++ code formatted by clang-format and using _clang-format.
libvideo.clang-format based on LLVM format.

For reformatting project files open main project folder and put command:

Windows

clang-format.exe -i -style=file Include/*.h src/*.h src/*.cpp src/Filters/*.h src/Filters/*.cpp src/FormatConvertors/*.h src/FormatConvertors/*.cpp src/WindowsManager/*.h src/WindowsManager/*.cpp test_package/*.cpp test_package/*.h

Linux

clang-format -i -style=file Include/*.h src/*.h src/*.cpp src/Filters/*.h src/Filters/*.cpp src/FormatConvertors/*.h src/FormatConvertors/*.cpp src/WindowsManager/*.h src/WindowsManager/*.cpp test_package/*.cpp test_package/*.h

Static code analyzing

C++ code analyzing by clang-tidy and using .clang-tidy.
For analyze code while build add --enable-tidy to prebuild thirdparty stage.
For example:

py .ci/prebuild_thirdparty.py --build-debug --enable-tidy
