POSIX compliant script for downloading content to a specified directory
using youtube-dl and then converting using ffmpeg.
To change the default options to suit your needs see 'Basic Configuration'
in dl.sh.
Usage: dl.sh [-e|--extension FILE_EXTENSION] [-s|--skip-ffmpeg]
[--youtube-dl YOUTUBE-DL_OPTION...] [--ffmpeg FFMPEG_OPTION...] [-h|--help] [-v|--version]
Everything read after --youtube-dl or --ffmpeg is considered an option for the corresponding program.
youtube-dl option interpretation comes to an end once --ffmpeg is met or vice versa.
--extension FILE_EXTENSION, --skip-ffmpeg, --version and --help should all precede
--youtube-dl or --ffmpeg in order for them to be interpreted as options passed to dl.sh.
For instance, in the example below, the options -f bestaudio -u $USER -p $PASSWD are interpreted by youtube-dl and,
and -vol 256 -i is interpreted by ffmpeg, not dl.sh.
dl.sh --youtube-dl -f bestaudio -u $USER -p $PASSWD --ffmpeg -vol 256 -i
-i flag for ffmpeg should come last since dl.sh calls ffmpeg as such:
eval "ffmpeg ""$ffmpeg_opt"" \"$file\" \"$new_file\""
where "$ffmpeg_opt" is all the options passed to ffmpeg, "$file" is the input file and "$new_file" is the output file.
--extension FILE_EXTENSION determines the file extension that the content will be converted into.
--skip-ffmpeg allows for dl.sh to skip ffmpeg conversion.
By default dl.sh sets ~/.dl.conf as its configuration file. Here's what the contents of ~/.dl.conf should look like:
"$HOME/$OUT_DIR"
https://www.example.com/1
https://www.example.com/2
https://www.example.com/3
https://www.example.com/4
where the first line is interpreted as the directory to which the content will be downloaded to. eval is used for interpretation thus
please use quotes whenever possible. Rest of the lines should all be valid URLs to downloadable content. If the directory in the configuration
file doesn't exist, it will be created. "$HOME", ~, 'My Home 123' are all valid directory names. (Don't forget to use quotes!)
