MM4 Not responding between songs

Post by MPG » Mon Aug 21, 2017 10:57 am

Hi,
Whenever MM4 segues from one song to another, it becomes unresponsive for about 10 seconds. The song continues to play, however, the application freezes. It appears to be working on displaying the artwork. I am running Auto-DJ off an auto playlist. MM4 is queuing up 5 songs as expected.

MM4 Version: 4.1.17.1840
Tracks:333,053
File Size: 2.28TB

Win10 1703
Build 15063.540
RAM: 16GB
Music is located on a single 4TB HDD with 1.04 TB remaining

TIA,

Does this happen under normal operation (no DJ, autoplaylist, etc.)?
What is your output plug-in, settings?

Hi MMFrLife,
I turned off Auto-DJ, while it had already cued up the next 5 songs. Lo and behold MM4 stayed responsive when it segued into the next song on the playlist. Therefore I think MM4 is taking a few seconds finding the next song to add based on the playlist criteria:
Path/Filename contains "D:\Music\Music Collection" (This is where all of my songs are that have been processed and are ready for consumption)
Played # = 0 (Only play songs I've never listened to)
Genre doesn't equal Christmas (Hey, it isn't Christmas season)

Sort = Random (This way, it randomly cycles through the available songs)

Based on the Library statistics, it would have to choose one from just over 200,000 songs. I guess MM can't make that selection without freezing. :-? :cry:
TIA

when was the last time you performed library maintenance?

I perform db maintenance about once a month. I did one about a month ago and this issue has been ongoing for a long time.

Is that the criteria for the playlist that you have selected to "Add files from" under the Auto-DJ settings? If so that would explain why MM freezes between songs.

Every time MM advances to the next track with Auto-DJ enabled it has to evaluate that playlist from scratch. Evaluating an auto playlist on a library of 315,000 tracks (taken from your signature) takes time, and 'Path/Filename contains' is one of the slowest criteria to evaluate so that will make it even slower.

Ideally MM would evaluate the Auto-DJ in a background thread to avoid this issue, but that would probably mean playback would stop if the playing track was the last track on the list; MM would finish the Now Playing list before it could add new tracks.

You could try these:
  • Change the Auto-DJ target to Entire Library to test how long MM freezes between tracks without having to evaluate the playlist.
  • Try tweaking the playlist criteria. Anything where you check values in a list will be faster than anything where you can type some text.
  • Workaround: Instead of using Auto-DJ just play the playlist. You have it sorted in random order so the result would essentially the same.

Try a different Output Plugin.

A solution to that is to recreate your path(s) and/or Filenames in a field like Grouping or Custom X and use that field to filter instead.
RegExpF&R add-on is great for copying the path to another field.
