Then you will need to get newer versions of the packages automake,Īutotools-dev, and libtool. (If you are on older releases of Debian/Ubuntu/Mint, like Debian/squeeze,

ANDROID FFMPEG LIBRARY INSTALL

On Debian/Ubuntu, run: apt-get install yasm bash patch make gawk The result is a single 'ffmpeg' that is statically linked, so its the only file you need. So here is my clean, easily changeable, static ffmpeg creator for Android. libpostproc : is a post processing library for use in transcode.ĭepending on the project requirements one can choose the libraries required to be integrated in the project.This is a new android-ffmpeg project since it seems there were so many different ways of doing it, it was confusing.(): this library performs highly optimized audio resampling, rematrixing and sample format conversion operations.() : this library performs highly optimized image scaling and colorspace and pixel format conversion operations.() : is a library that handles audio resampling, sample format conversion and mixing.() : provides a generic audio/video filtering framework containing several filters, sources and sinks.() : provides a generic framework for grabbing from and rendering to many common multimedia input/output devices, and supports several input and output devices, including Video4Linux2, VfW, DShow, and ALSA.() : provides a generic framework for multiplexing and demultiplexing (muxing and demuxing) audio, video and subtitle streams.

() : is a utility library to aid portable multimedia programming.

(): provides a generic encoding/decoding framework and contains multiple decoders and encoders for audio, video and subtitle streams, and several bitstream filters.

ANDROID FFMPEG LIBRARY CODE

Static:Static libraries are the .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). 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.

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 :.

ANDROID FFMPEG LIBRARY 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.
