Downloading Embedded Streaming Videos (m3u8)

00_instructions.md

1. Get link to .m3u8

Go to the Network tab of your browser and find the file that ends in .m3u8, then its URL.

2. Install Prerequisites

You'll need youtube-dl and ffmpeg for this. In macOS, you can just use brew to install them. I will optionally install gum coz I like my scripts fancy hahaha

brew install ffmpeg
brew install youtube-dl
brew install gum        # Optional

3. Download video

Run download.sh.

download.sh

gum style \
	--foreground 212 --border-foreground 212 --border double \
	--align center --width 50 --margin "1 2" --padding "2 4" \
	'Embedded Video Downloader! (.m3u8)'

function download_video() {
  master_file=$1
  output_file=$2
  best_format=$(youtube-dl --list-formats ${master_file} | grep "(best)" | awk '{print $1}')
  gum spin --spinner globe --title "Downloading '${output_file}.mp4'..." -- youtube-dl --format "${best_format}" --output "${output_file}.mp4" ${master_file}
  gum spin --spinner globe --title "Downloading '${output_file}.aac'..." -- youtube-dl --format "AAC-Default" --output "${output_file}.aac" ${master_file}
  gum spin --spinner minidot --title "Combining video and audio files into '${output_file}.mkv'..." -- ffmpeg -i "${output_file}.mp4" -i "${output_file}.aac" -c copy "${output_file}.mkv"

  gum style \
    --foreground 212 --border-foreground 212 --border double \
    --align center --width 50 --margin "1 2" --padding "2 4" \
    "Completed download of '${output_file}.mkv'."
}

batch_or_single=$(gum choose single batch)

if [[ "${batch_or_single}" == "batch" ]]; then
  batch_file_url=$(gum file .)
  downloadz=( $(cat ${batch_file_url}) )

  for download in ${downloadz[@]}
  do
    values=($(echo "${download}" | tr ',' '\n'))
    master_file="${values[0]}"
    output_file="${values[1]}"
    download_video "${master_file}" "${output_file}"
  done
else
  master_file=$(gum input --char-limit 0 --placeholder "Link to .m3u8")
  output_file=$(gum input --char-limit 0 --placeholder "Output file name")
  download_video "${master_file}" "${output_file}"
