Create playlist for one file that is a full album

[myQwil]

Occasionally I will come across audio files that are entire albums instead of being broken down into individual tracks.
Is there currently any way to create a playlist that lists all of the start and stop times of each track, which could then be navigated with VLC's playlist view as if they were individual tracks?

After looking into the xspf format, I found that vlc has the following options:

Code: Select all

<vlc:option>start-time=TIME</vlc:option> <vlc:option>stop-time=TIME</vlc:option>

Though it would still be nice if the trackbar focused on the start/stop time specified. If the album is long but the specific track is short, it becomes virtually impossible to seek with the trackbar. And despite specifying a duration for each track, that seems to be ignored and the duration of the full album is displayed instead.

Also, my understanding is that these options only work with a few file formats (avi, mov, mkv, mp4), so if it's an mp3, flac, etc., presumably it won't be a viable option.

I ended up making a git patch for this. Probably doesn't warrant a pull request but here it is for anyone interested:

Code: Select all

This makes it so that the trackbar focuses in on the start/stop time specified in the xspf file.
