Golang-Client which enables you to seamlessly integrate the Bitmovin API into your projects. Using this API client requires an active account. Sign up for a Bitmovin API key.
The full Bitmovin API reference can be found on our website.
Installation
Run go get github.com/bitmovin/bitmovin-go
Also feel free to use your favorite go dependency manager such as glide.
Example
The following example creates a simple transcoding job with a HTTP Input and a S3 Output (create_simple_encoding.go):
package main

"github.com/bitmovin/bitmovin-go/bitmovintypes"
"github.com/bitmovin/bitmovin-go/models"
"github.com/bitmovin/bitmovin-go/services"
)

// Creating Bitmovin object
