Here's part of my script:
mpv https://www.youtube.com/playlist?list=PLNQL50H--29oy5MOaxEVjcxhX-5Vvskji --shuffle --no-video --input-file=~/.config/mpv/mpv-fifo > data.txt
Here's an example of what's printed to file:
Playing: https://www.youtube.com/playlist?list=PLNQL50H--29oy5MOaxEVjcxhX-5Vvskji
Playing: ytdl://a-XXr1H1FeI
(+) Audio --aid=1 --alang=eng (*) (vorbis 2ch 44100Hz)
AO: [pulse] 44100Hz stereo 2ch float
All I want is the youtube video id 'a-XXr1H1FeI' - that is after 'Playing: ytdl://'. Each id is one song from a playlist of hundreds and I have several playlists.
I would like to have the current song id in a file. This will allow me to grab the song title with youtube-dl and display it with conky. I can also use it to print the id to another file if I skip a song and then later delete the skipped songs from my youtube playlists and so better curate them.
I tried the sed and grep solutions from here: Return only the portion of a line after a matching pattern and they would print nothing.
I'm using playlists; so this solution: Make mpv display name of youtube link when playing just audio doesn't work.
Here's what I've tried to do with sed:
This produces nothing.
mpv https://www.youtube.com/playlist?list=PLNQL50H--29oy5MOaxEVjcxhX-5Vvskji --shuffle --no-video --input-file=~/.config/mpv/mpv-fifo | sed -n 's~^Playing: ytdl://\(.*\)~\1~p' > data.txt
This gives me the ids I want, but not until I stop the script. I need them while the songs are playing.
mpv https://www.youtube.com/playlist?list=PLNQL50H--29o5FarbAFHBaUNRu2ipp4th --shuffle --no-video --input-file=~/.config/mpv/mpv-fifo > data.txt
sed -n 's~^Playing: ytdl://\(.*\)~\1~p' data.txt > out.txt
Update: This doesn't actually work but I think it's close.
mpv $url --shuffle --no-video --input-file=~/.config/mpv/mpv-fifo > ~/data.txt &
until [ "$1" = "q" ]
do
sed -n 's~^Playing: ytdl://\(.*\)~\1~p' ~/data.txt > ~/out.txt
> ~/data.txt
sleep 5
done
Update:
It sort of works when I change data.txt > out.txt to ~/data.txt >> ~/out.txt which gives me a list of the ids that have generated, not the single current id. I could work with that I suppose. Also, the loop doesn't seem to stop when "$1" = "q". I'm not sure what's going on with that. I've found another way to kill the script though.
Here's the entire script. I can work with it as is, but it's kind of a kludge. I'll leave it for a couple of days and then call it solved if no one helps.
