Better C bindings for ffmpeg in GO

astiav is a Golang library providing C bindings for ffmpeg

It's only compatible with ffmpeg n5.1.2.

Its main goals are to:

• provide a better GO idiomatic API
  • standard error pattern
  • typed constants and flags
  • struct-based functions
  • ...
• provide the GO version of ffmpeg examples
• be fully tested

Examples

Examples are located in the examples directory and mirror as much as possible the ffmpeg examples.

Tip: you can use the video sample located in the testdata directory for your tests

Install ffmpeg from source

If you don't know how to install ffmpeg, you can use the following to install it from source:

$ make install-ffmpeg

ffmpeg will be built from source in a directory named tmp and located in you working directory

For your GO code to pick up ffmpeg dependency automatically, you'll need to add the following environment variables:

(don't forget to replace {{ path to your working directory }} with the absolute path to your working directory)

export CGO_LDFLAGS="-L{{ path to your working directory }}/tmp/n5.1.2/lib/",
export CGO_CFLAGS="-I{{ path to your working directory }}/tmp/n5.1.2/include/",
export PKG_CONFIG_PATH="{{ path to your working directory }}/tmp/n5.1.2/lib/pkgconfig",

Why astiav?

After maintaining for several years the most starred fork of goav, I've decided to write from scratch my own C bindings to fix most of the problems I still encountered using goav.
