Getting started
The FFmpeg module allows you to integrate FFmpeg for video playback into Godot. The code is inspired by osu’s video decoder, but improved with new features, such as support for audio playback.
Downloads
The latest downloads can be found here.
Installation
Installation is as simple as placing the addons folder from the extension at the root of your Godot project, Godot should automatically pick it up.
Usage
Any compatible file will be automatically picked up by the engine when you add it to your project, you can also make an instance of
FFmpegVideoStream and set the file property to the path of the file you want to play.
Performance
Performance should be better than the old godot-videodecoder, but it’s not ideal, there’s no hardware decoding support (yet, not sure if it’s even possible) and it doesn’t make use of YCbCr when available, which would save a complete conversion step.
Another potential optimization would be to allocate and write directly to a godot Vector<uint8_t> type, this is because a Vector<uint8_t> is needed
to update textures, which is a godot internal copy on write container that cannot be created without copying the whole frame to it.
The FFmpeg library
The extension comes with a stripped down build of the ffmpeg library that is automatically built to use an old as possible version of glibc, that way it’s compatible with all systems, this is downloaded from here during the compilation process.
This version also removes most codecs, the available codecs and demuxers are printed on startup.
If you want to use your own ffmpeg library, it’s likely that you can simply replace the .so and .dll files with your build of a similar version.
The LGPL builds found here should also be compatible.
Supporting development
This module was kindly released by EIRTeam as a part of the open source initiative to drive more funds to continue development of Project Heartbeat and to sustain myself, if you want to support development, please donate to our Patreon.
