This is important because starting up an external executable tends to be blocked by antivirus software and can cause issues with users. I developed this project to be able to to integrate FFmpeg into our program without having to call the executable to do an operation. If you want to use ffmpeg-cpp in a C# project, you can easily do so by making your own C-wrapper around the Why?

If you use the included simple-interface library, which only supports a subset of the full library, using ffmpeg-cpp becomes even easier: Save everything to disk by closing the muxer. Push all the remaining frames through. This will decode a small amount of frames so the pipeline can configure itself. Pick the best video stream container in the container // And send it to the filter.ĭemuxer* demuxer = new Demuxer( 'big_buck_bunny.mp4 ') Create a video filter and do some funny stuff with the video data.įilter* filter = new Filter( 'scale=640:150,transpose=cclock,vignette ', encoder) VideoEncoder* encoder = new VideoEncoder(codec, muxer) Tie it to the muxer so it will be written to file. Create an encoder that will encode the raw audio data using the codec specified above. VideoCodec* codec = new VideoCodec(AV_CODEC_ID_MPEG2VIDEO) Create a MPEG2 codec that will encode the raw data. Muxer* muxer = new Muxer( 'filtered_video.mp4 ') Create a muxer that will output the video as MP4.

To give you an idea, this code will load a video stream from a container, filter it, and write it back out to another container: NET Core compatible simplified interface included so that you can embed this project in your. Check out the demo-project for a thorough exploration of the features (demuxing, decoding, filtering, encoding, muxing) or one of the other examples for a simpler example to follow. There are multiple demo projects included in the solution. If anyone is willing to help me out with configuring cmake, please get in touch! Usage This is simply because I do not have experience with cmake and Linux-projects, since the project itself is fully platform-independent. LinuxĬurrently, only a Windows environment with Visual Studio is supported. It will also generate an include-folder in the repo root that you can add to your include filders in your own project. lib file that you can use in your own C++ projects.

Open the Visual Studio solution in the source directory.

there are more instructions on how to extract them properly in the ffmpeg/readme.txt file. Extract all of them into the ffmpeg directory in the repository. The full power of FFmpeg compacted in 10 lines of C++ code: if this sounds useful to you, read on! Installation Windows Makes the most commonly used functionality of FFmpeg easily available for any C++ projects with an easy-to-use interface. A clean C++ wrapper around the ffmpeg libraries which can be used in any C++ project or C# project (with DllImport or CLR).
