FFmpeg and SDL2 based library for audio and video playback, written in C99.
Documentation is available at http://katajakasa.github.io/SDL_kitchensink/
- Decoding video, audio and subtitles via FFmpeg
- Dumping video and subtitle data on SDL_textures
- Dumping audio data in the usual mono/stereo interleaved formats
- Automatic audio and video conversion to SDL2 friendly formats
- Synchronizing video & audio to clock
- Seeking forwards and backwards
- Bitmap, text and SSA/ASS subtitle support
Note! Master branch is for the development of v1.0.0 series. v0 can be found in the rel-kitchensink-0 branch. v0 is no longer in active development and only bug- and security-fixes are accepted.
1. Library requirements
- CMake (>=3.0)
- GCC (C99 support required)
- SDL2 (>=2.0.5)
- FFmpeg (>=3.0)
- libass (optional, supports runtime linking via SDL_LoadSO)
Note that Clang might work, but is not tested. Older SDL2 and FFmpeg library versions may or may not work; versions noted here are the only ones tested.
1.1. Debian / Ubuntu
sudo apt-get install libsdl2-dev libavcodec-dev libavdevice-dev libavfilter-dev \ libavformat-dev libavresample-dev libavutil-dev libswresample-dev libswscale-dev \ libpostproc-dev libass-dev
1.2. MSYS2 64bit
These are for x86_64. For 32bit installation, just change the package names a bit .
pacman -S mingw-w64-x86_64-SDL2 mingw-w64-x86_64-ffmpeg mingw-w64-x86_64-libass
By default, both static and dynamic libraries are built.
- Dynamic library is called libSDL_kitchensink.dll or .so
- Static library is called libSDL_kitchensink_static.a
- If you build in debug mode (
-DCMAKE_BUILD_TYPE=Debug), libraries will be postfixed with 'd'.
Change CMAKE_INSTALL_PREFIX as necessary to change the installation path. The files will be installed to
- CMAKE_INSTALL_PREFIX/lib for libraries (.dll.a, .a, etc.)
- CMAKE_INSTALL_PREFIX/bin for binaries (.dll, .so)
- CMAKE_INSTALL_PREFIX/include for headers
2.1. Building the libraries on Debian/Ubuntu
mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local ..
sudo make install
2.2. Building the libraries on MSYS2
mkdir build && cd build
cmake -G "MSYS Makefiles" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local ..
2.3. Building examples
-DBUILD_EXAMPLES=1 to cmake arguments and rebuild.
2.4. Building with AddressSanitizer
This is for development/debugging use only!
Make sure llvm is installed, then add
-DUSE_ASAN=1 to the cmake arguments and rebuild. Note that ASAN is not
supported on all OSes (eg. windows).
After building, you can run with the following (make sure to set correct llvm-symbolizer path):
ASAN_OPTIONS=symbolize=1 ASAN_SYMBOLIZER_PATH=/usr/bin/llvm-symbolizer ./examplevideo <my videofile>
3. Why the name SDL_kitchensink
Because pulling major blob of library code like ffmpeg feels like bringing in a whole house with its kitchensink and everything to the project. Also, it sounded funny. Also, SDL_ffmpeg is already reserved :(
Please see examples directory. You can also take a look at unittests for some help. Note that examples are NOT meant for any kind of real life use; they are only meant to show simple use cases for the library.
5. FFMPEG & licensing
Note that FFmpeg has a rather complex license. Please take a look at FFmpeg Legal page for details.
