C++ wrapper for FFmpeg

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

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 and Linux Mint

You should add ffmpeg-3 PPA:

sudo add-apt-repository ppa:jonathonf/ffmpeg-3 -y
sudo add-apt-repository ppa:jonathonf/tesseract -y
sudo apt update && sudo apt upgrade
sudo apt install libavcodec-dev \
                 libavdevice-dev \
                 libavfilter-dev \
                 libavformat-dev \
                 libavresample-dev \
                 libavutil-dev \
                 libpostproc-dev \
                 libswresample-dev \
                 libswscale-dev

Near future plans

• Building for Android (ready to commint but small code clean up is required)
• CI with complex build matrix:
  • FFmpeg 3.x and FFmpeg 2.8
  • GCC 5 and 7, MSVS 2015 and 2017, clang
  • Linux, OSX, Windows
  • Tests

Future plans (long and not)

• Code cleanup
• Remove all deprecates in Filters module (FFmpeg 2.x)
• API redisign, make it more intuitively
• Filters module complete rework
• Add good samples
• Make hight-level entities like av::Encoder, av::Decoder, av::Muxer, av::Demuxer and declare some API to combine them.
• More advanced Android building
