yt-dlp uses mp4 format by default to merge sources with separate video and audio streams. mp4 format does not handle VP9 codec, so adding the ability to set the merge output format, we can set it to use for ex. mkv, which handles VP9 well. With the possibility of setting the sorting format we can tell yt-dlp which criteria to consider as the best format.
goutubedl
Go wrapper for youtube-dl and yt-dlp, currently tested and developed using yt-dlp. API documentation can be found at godoc.org.
See yt-dlp documentation for how to install and what is recommended to install in addition to youtube-dl.
goutubedl default uses PATH to find youtube-dl but it can be configured with the goutubedl.Path
variable. Default is currently youtube-dl for backwards compability. If your using yt-dlp you
probably want to set it to yt-dlp.
Due to the nature and frequent updates of youtube-dl only the latest version is tested. But it seems to work well with older versions also.
Usage
From cmd/example/main.go
package main
import (
"context"
"io"
"log"
"os"
"github.com/wader/goutubedl"
)
func main() {
result, err := goutubedl.New(context.Background(), "https://www.youtube.com/watch?v=jgVhBThJdXc", goutubedl.Options{})
if err != nil {
log.Fatal(err)
}
downloadResult, err := result.Download(context.Background(), "best")
if err != nil {
log.Fatal(err)
}
defer downloadResult.Close()
f, err := os.Create("output")
if err != nil {
log.Fatal(err)
}
defer f.Close()
io.Copy(f, downloadResult)
}
