Using a computer to select tracks for playback on device (iPod 5/Video) via USB

[PlainRamenNoodles]

This may already exist, but all I saw were ways to use a Rockbox Device to control playback on a computer. I want the reverse: using a computer to select a track for playback on the device. It would be more complicated than "Skip Track" and "Volume Up",

I am making an old, wooden, console radio into an audiobook machine that uses NFC tags to select the story. I could just load all the audiobooks onto the Raspi that I'm using as the brain, but I would really like to still be able to take the audiobooks with me. So, I'd like to use a docked iPod as the storage, preferably keeping my position when I stop or take it off the dock.

I see in the manual how I could use the iPod as a filesystem, and play the files through the Raspi, but is there a way for the Raspi to communicate to the iPod that it wants the iPod to play a certain track, preferably picking up at the latest bookmark for that track? Does not need to be a GUI, command-line is fine.

Pick your song on the raspi and manually create the resume info for the track (see ./rockbox/.resume.cfg) and write it to the ipod then when rockbox resumes it'll pick up your track and current track pos

you could also do it with a whole playlist...

As far as two way communication you'd have to create something maybe the (deprecated) alpine headunit plugin could work for some ideas but nothing ready made..

Wouldn't really need two way communication, as I only want to play music from the iPod, using the raspi as a remote of sorts.Thank you!
