I have been following a pattern of checking if there is anything in the channel before proceeding with work: func consume(msg <-chan message) { for { if m, ok := <-msg; ok { fmt.Println("More messages:", m) } else { break } } } that is based on this video [this video] . Here is my full code: package main import ( "fmt" "strconv" "strings" "sync" ) type message struct { body string code int } var markets []string = []string{"BTC", "ETH", "LTC"} // produces messages into the chan func produce(n int, market string, msg chan<- message, wg *sync.WaitGroup) { // for i := 0; i < n; i++ { var msgToSend = message{ body: strings.Join([]string{"market: ", market, ", #", strconv.Itoa(1)}, ""), code: 1, } fmt

I'm trying to write a program that downloads a portion of a video using yt-dlp to get the stream link and ffmpeg to download the video. Here's what the program will do: Ask the user for the video link, then pass the link to original_link variable Ask the user for start time and end time, then pass those to start_time and end_time respectively. Using subprocess , call the shell command yt-dlp --get-url <original_link> . yt-dlp will output links line-by-line. If the stream is from Twitch, it is HLS and yt-dlp will return one link only (and the link will be used for both video and audio input). If the stream is from services such as Youtube, yt-dlp will return two links: one audio stream and on
