#FFMPEG ANDROID GITHUB PORTABLE#
libavutil : is a utility library to aid portable multimedia programming.libavcodec: provides a generic encoding/decoding framework and contains multiple decoders and encoders for audio, video and subtitle streams, and several bitstream filters.a files.All the code related to the library is in this file, and it is directly linked into the program at compile time.Ī program using a static library takes copies of the code that it uses from the static library and makes it part of the program.įFmpeg contains a set of shared libraries which can be used for different operations: so files.All the code related to the library is in this file, and it is referenced by programs using it at run-time.Ī program using a shared library only makes reference to the code that it uses in the shared library. There are two kinds of libraries in C/C++ These tutorials will help you through the hurdle of cross compilation.Īfter compilation you will have the ABIs as shown below: Here are some of the tutorials I followed to generate the libraries. Having worked with some of the hardware related projects helped me a lot as the terminology was not sounding alien to me anymore ?. compiling the FFmpeg source code to generate libraries for android( Cross- Compilation).
#FFMPEG ANDROID GITHUB FOR ANDROID#
Often these methods are used in combination to obtain the desired results Compiling FFmpeg for Android To crop a video or play live streams - Transcoding To convert one format to another - Remuxing Transsizing refers to changing the picture size of video, and is useful if the output resolution differs from the resolution of the media.ĭepending on the requirements one can choose remuxing or transcoding. Transrating is the process by which video files and audio files are converted to a reduced bit rate while still maintaining the original media format. Remuxing is a lossless process that is used to change the container format of a given file(e.g. Integrating FFmpeg with Android applicationįor one of the projects there was a requirement to use FFmpeg for video processing.Being new to using FFmpeg I came across remuxing, transcoding, transrating and the transsizing process which are required to process videos. Android NDK:Using Kotlin Episode 3- Callbacks continued.Android NDK:Using Kotlin Episode 2- Callbacks(kotlin to cpp).Android NDK:Using Kotlin Episode 1- The Concepts.Create a wrapper around the pre-built library to use with your android application.įor information on NDK basics and callbacks from native code you can look into my previous articles :.
#FFMPEG ANDROID GITHUB HOW TO#
How to integrate pre-built libraries with Android app e.g.Through this article I will be explaining Android SDK provides APIs for most of the common work which a developer uses every day like direct share, app linking, fingerprint authentication and so on.Sometimes we might need to work on low-level functionality which mostly are available as C/C++ libraries.With Android NDK we can use these pre-built libraries by creating a C/C++ wrapper around it and the use JNI to invoke the native code from Kotlin/Java.
