+# go-mediainfo
+
+Go bindings for [MediaInfo](https://github.com/MediaArea/MediaInfoLib)
+
+## Dependencies

+### ubuntu 18.04
+
+```bash
+sudo apt-get install libmediainfo0v5 libmediainfo-dev
+```
+
+## Usage
+
+### Open file
+
+```go
+file, err := mediainfo.Open("/file/path/filename.mp4")
+if err != nil {
+    log.Fatal(err)
+}
+defer file.Close()
+```
+
+### Bitrate
+
+```go
+videoBitrate := file.Parameter(mediainfo.StreamVideo, 0, "BitRate")
+audioBitrateTrack1 := file.Parameter(mediainfo.StreamAudio, 0, "BitRate")
+audioBitrateTrack2 := file.Parameter(mediainfo.StreamAudio, 1, "BitRate")
+```
+
+### Stream count
+
+```go
+audioTracks := file.Parameter(mediainfo.StreamAudio, 0, "StreamCount")
+```
+
+### Available parameters
+
+```go
+parameters := file.Option("info_parameters", "")
+```
