goav

Golang binding for FFmpeg 3.2.xx. Forked from here

A binding to the ffmpeg video/audio manipulation library. It's incomplete but I am able to decode frames of ProRes.

Usage

See go-prores-ffmpeg as an example.

I found the original examples weren't complete.

Libraries

• avcodec corresponds to the ffmpeg library: libavcodec [provides implementation of a wider range of codecs]
• avformat corresponds to the ffmpeg library: libavformat [implements streaming protocols, container formats and basic I/O access]
• avutil corresponds to the ffmpeg library: libavutil [includes hashers, decompressors and miscellaneous utility functions]
• avfilter corresponds to the ffmpeg library: libavfilter [provides a mean to alter decoded Audio and Video through chain of filters]
• avdevice corresponds to the ffmpeg library: libavdevice [provides an abstraction to access capture and playback devices]
• swresample corresponds to the ffmpeg library: libswresample [implements audio mixing and resampling routines]
• swscale corresponds to the ffmpeg library: libswscale [implements color conversion and scaling routines]

Installation

Depends on FFMpeg 3.2.xx: install instructions here. Note: This version is included in Ubuntu 16.10 (Yakkety), but Ubuntu 16.04 (Xenial) is still on 2.7.xx. You will need to install an updated version

sudo apt-get -y --force-yes install autoconf automake build-essential libass-dev libfreetype6-dev libsdl1.2-dev libtheora-dev libtool libva-dev libvdpau-dev libvorbis-dev libxcb1-dev libxcb-shm0-dev libxcb-xfixes0-dev pkg-config texi2html zlib1g-dev

sudo apt-get install yasm
