Mediainfo wrapper for Golang

Yet Another MediaInfo Go Wrapper

This wrapper allows you to run mediainfo and parse its output in usable manner.

Yami is inspired of go-ffprobe and can be used as a drop-in replacement with minor changes in mapping.

Current version mapping matches XML v2

Example

package main

import (
	"github.com/cajax/yami"
	"log"
	"time"
)

func main() {
	mediainfo, err := yami.GetMediaInfo("video.mp4", 10*time.Second)

	if err != nil {
		log.Panic(err)
	}

	video := mediainfo.GetFirstVideoTrack()

	log.Printf("Video Codec:\t%s", video.CodecID)
	log.Printf("Framerate:\t\t%f", video.FrameRate)
}

yami's Issues

Error trying to use the Inform argument with mediainfo

mediainfo -f --Output=XML --Inform='file:///mi/mediainfo_fields.txt' /clip.mp4

Running this from CLI works but unable to pass the Inform argument with yami.GetMediaInfo()

yami.GetMediaInfo(inputFile, 30*time.Second, "--Inform='file:///mi/mediainfo_fields.txt'")

Error:
{"level":"FATAL","ts":"2021-12-08T18:57:26.678Z","msg":"error getting mediainfo output","error":"EOF"}

Could you please advise if filtering down to only parse required fields is supported and how can we use the --Inform flag to pass to mediaInfo call as argument.
Thanks

call yami.GetMediaInfo() got types error

I got an error when call yami.GetMediaInfo(): strconv.ParseFloat: parsing "UTC 2020-05-08 08:00:26": invalid syntax.
followed the source code, I found in yami/types.go, "DurationStart" and "DurationEnd" are declared in wrong type, they are string instead of float64

Type Text ?

Add type Text as constant to your lib. Example:

Text #1
ID : 4
Format : PGS
Codec ID : S_HDMV/PGS
Codec ID/Info : Picture based subtitle format used on BDs/HD-DVDs
Duration : 2 h 20 min
Bit rate : 43.6 kb/s
Count of elements : 4708
Stream size : 44.0 MiB (0%)
