Bug? “Error accessing playlist control file” using %Vp

[RetiredTeacherGuy]

I am able to successfully use “ %Vp(0,%it)” on cs=1 of the sbs. However, if the device is plugged into USB, when exiting I get “Error accessing playlist control file” every time.

Which build do you have installed?

Version 68f511984e-250114

If you don't mind, try upgrading to see if the issue is still reproducible on the very latest daily (or dev) build.

Will do, thanks

Hi Chris, still happening on Ver. 96463d8551-259119

thanks for checking - you should not see the error message anymore in the latest dev build (2debcf2c1f), or in any upcoming daily builds

Thanks. chris, is there a way to access the playlist file without a track first being played?

[chris_s]

sure, you can select "View Current Playlist" from the Playlist Catalogue's context menu:

Right but for theming purposes, when I try to use %Vp it seems to return empty if/until I start the playlist. Example: The iPod has been shut down. I start it up and if I have %Vp in a viewport, I don’t see any info, but if I restart the playlist then come back to the sbs, I will see the info.

That is true. Even though it appears to be possible, I'm not sure the custom skin playlist viewer was ever expected to be included in an SBS instead of the WPS. As you noticed, it only shows something while playing or paused.

Showing current and upcoming tracks when playback is stopped - including after a reboot - would require larger changes - most importantly, automatically "resuming" a playlist (i.e. parsing its control file)  when the player boots up, in order to restore the playlist state. And then making sure the state is maintained. While this should be possible, it has certain disadvantages as well, such as slowing down the boot process: Depending on your dircache size, this could be very noticeable due to the fact that the system currently waits for the dircache to have finished loading before resuming a playlist.

Thanks for the background, makes sense

[Bilgus]

wonder if you could screenshot and restore it

[RetiredTeacherGuy]

you lost me at “screenshot” care to expound?

[Bilgus]

like would it work take a copy of the screen then restore that on boot later or do you need to interact with it too?
