Summary0011549: Playlist video thumbnails appear very slowly, disappear, re-appear (regression)
DescriptionIn the playlists view, for playlists that contain videos the thumbnails appear very slowly, and often disappear.

1 Sync 5 playlists: 3 with music only, 2 with a combination of videos and music
2 View the playlists node
--> It takes about 5-10 seconds for the thumbnails to appear!
--> The thumbnails disappear after briefly appearing!
--> The thumbnails then are regenerated and re-appear!
3 Let the device screen timeout kick in
4 Sign back in to the device
--> MMA appears in the playlists view, and again, the thumbnails disappear!
5 Wait for the thumbnails to appear, and close MM
6 Restart MM after it stops running entirely, and go to the playlists node
--> The thumbnails disappear again!

It seems that they disappear temporarily whenever the scanning process is active.

Note: the bug
TagsNo tags attached.
Fixed in build200

This issue seems to have gotten worse in build 193/194.

a) Playlist thumbnails disappear:
 - After exiting MMA and restarting MMA
 - After playing a playlist and then backing out of NP view to Playlists (after a minute or so)
 - Anytime a scan occurs while in the playlists view (e.g. after a sync)
 - etc.

Note also, that sometimes, upon entering the Playlists view, thumbnails are all missing, and they'll all reappear after about 5 seconds. Then a couple of seconds later, they'll all disappear (I think that this is related to scanning taking place). Then they'll gradually re-appear as described below.

b) Playlists take awhile to appear. For newly synced playlists OR whenever case a) occurs, it can take several seconds for thumbnails to appear. It seems that larger playlists take much longer to generate thumbnails than short playlists, which implies that the process is somehow processing the entire playlist rather than just the first 3 tracks.

e.g. for the following Playlist view

Playlist 1 . . . 5 tracks
Playlist 2 . . . 10 tracks
Playlist 3 . . . 6 tracks
Playlist 4 . . . 5 tracks
Playlist 5 . . . 1064 tracks
Playlist 6 . . . 5 tracks
Playlist 7 . . . 8 tracks
Playlist 8 . . . 6 tracks

Thumbnails for Playlists 1-4 appear almost immediately
Thumbnails for Playlist 5 Then take about 12s to appear
Thumbnails for Playlist 6-8 Appear immediately after the thumbnail for playlist 5

Tested 197. This is much better now, as the flashing of playlist thumbnails no longer occurs, and the situations in which thumbnails disappear seems to be more limited. However:

a) Playlist thumbnails still do disappear after each sync operation--even if the sync has no effect on playlists or playlist thumbnails

b) If thumbnails are being created (e.g. for a new sync or when a) occurs), it still takes 12 seconds for the thumbnails to appear

re. a) Playlist thumbnails are refreshed only if any media is deleted, inserted or updated in sync operation. We don't detect whether changed media belongs to some playlist, because it could be little more complicated. Moreover I guess it's not necessary in build 200, because refresh should be much quicker.

re b) I have improved sql for loading album arts and video thumbnails - it should help. But new playlist with new video has to generate its thumbnails. This operation can take a few seconds and block other playlists to appear its thumbnails, but only for first time.

Fixed in build 200.
