AvCpp

Wrapper for the FFmpeg that simplify usage it from C++ projects.

Currently covered next functionality:

• Core helper & utility classes (AVFrame -> av::AudioSample & av::VideoFrame, AVRational -> av::Rational and so on)
• Container formats & contexts muxing and demuxing
• Codecs & codecs contexts: encoding and decoding
• Streams (AVStream -> av::Stream)
• Filters (audio & video): parsing from string, manual adding filters to the graph & other
• SW Video & Audio resamplers

Requirements

• FFmpeg >= 2.0
  • libavformat >= 54.x.x
  • libavcodec >= 54.x.x
  • libavfilter >= 3.x.x
  • libavutil >= 51.x.x
  • libswscale >= 2.x.x
  • libswresample >= 0.x.x
  • libpostproc >= 52.x.x
• GCC >= 5.0 (C++11 is required)

Debian, Ubuntu 19.10 and Linux Mint 20.x or newer

You should install FFmpeg packages from the deb-multimedia.org site:

sudo apt-get install libavformat-dev \
                     libavcodec-dev \
                     libavutil-dev \
                     libavfilter-dev \
                     libswscale-dev \
                     libswresample-dev \
                     libpostproc-dev

Note 1: I did not test building on Debian.

Note 2: Debian Wheezy repo contains only FFmpeg 1.0.8. I tested building only with 2.x. So it is strongly recoment use Wheezy back-ports repo.

Ubuntu 18.04 and Linux Mint 19.x

If you are on Ubuntu bionic or Linux Mint 19.x you should add ffmpeg-4 PPA:

sudo add-apt-repository ppa:jonathonf/ffmpeg-4 -y
sudo apt update && sudo apt upgrade

After that just install the same packages as above.

Build

git clone --recurse-submodules https://github.com/h4tr3d/avcpp.git avcpp-git
cd avcpp-git
mkdir build
cd build
cmake ..
make -j8

If your Git version so old (refer to the SO for clarification) you can just replace --recurse-submodules with pair of git submodule init && git submodule update.

If FFmpeg located in non-standard place:

cmake -DPC_FFMPEG_LIBRARY_DIRS=<some_path> -DPC_FFMPEG_INCLUDE_DIRS=<some_path> ..

To point install prefix:

cmake -DCMAKE_INSTALL_PREFIX=/usr ..

Install:

sudo make install

or (for packaging)

sudo make DESTDIR=<some_prefix> install

Refer to CMake documentation for more details that can cover some special cases.
