go-gst
Go bindings for the gstreamer C library
This package was originally written to aid the audio support in kvdi
.
But it made sense to turn it into an independent, consumable package. The intention now is to progressively implement the entire API.
See the go.dev reference for documentation and examples.
For other examples see the command line implementation here.
TODO: Write examples on programatically building the pipeline yourself
Requirements
For building applications with this library you need the following:
cgo
: You must setCGO_ENABLED=1
in your environment when buildingpkg-config
libgstreamer-1.0-dev
: This package name may be different depending on your OS. You need thegst.h
header files.
For running applications with this library you'll need to have libgstreamer-1.0
installed. Again, this package may be different depending on your OS.
CLI
There is a CLI utility included with this package that demonstrates some of the things you can do.
For now the functionality is limitted to GIF encoing and other arbitrary pipelines.
If I extend it further I'll publish releases, but for now, you can retrieve it with go get
.
go get github.com/tinyzimmer/go-gst/cmd/go-gst
The usage is described below:
Go-gst is a CLI utility aiming to implement the core functionality
of the core gstreamer-tools. It's primary purpose is to showcase the functionality of
the underlying go-gst library.
There are also additional commands showing some of the things you can do with the library,
such as websocket servers reading/writing to/from local audio servers and audio/video/image
encoders/decoders.
Usage:
go-gst [command]
Available Commands:
completion Generate completion script
gif Encodes the given video to GIF format
help Help about any command
inspect Inspect the elements of the given pipeline string
launch Run a generic pipeline
websocket Run a websocket audio proxy for streaming audio from a pulse server
and optionally recording to a virtual mic.
Flags:
-I, --from-stdin Write to the pipeline from stdin. If this is specified, then -i is ignored.
-h, --help help for go-gst
-i, --input string An input file, defaults to the first element in the pipeline.
-o, --output string An output file, defaults to the last element in the pipeline.
-O, --to-stdout Writes the results from the pipeline to stdout. If this is specified, then -o is ignored.
-v, --verbose Verbose output. This is ignored when used with --to-stdout.
Use "go-gst [command] --help" for more information about a command.
