Description Nicola B 2024-03-29 16:32:24 UTC

SUMMARY
When launch at startup Elisa still freeze for long time, (if you are on powersave management profile, for very long time) so need to go in performance to "unlock" Elisa. My local library count is only 12k flac file indexed (of my over 70k total flac's) with "native" engine but same happen with "direct read" behavior.
My laptop with Crucial P5 nvme pci 4.0 drive, so I'm sure isn't bandwidth transfer rate issue lol.

STEPS TO REPRODUCE
1. Get high performance hardware to ensure you are on good speed performance.
2. Set on Elisa library folder with high amount of flac's >12.000 files.
3. After indexing, restart Elisa.

OBSERVED RESULT
Elisa GUI (buttons and other clickable objects still "hold" for a while, no playback, long or short times depends by your CPU power available.

EXPECTED RESULT
Elisa must start playing audio tracks immediately after launching, index checking behavior must be done in background and not impact on user interface or listen if your library high count files.

MediaPlayListProxyModel: add timer to prevent excesive function/signal calls

remainingTracksDurationChanged and totalTracksDurationChanged are emitted more than 3K times
for a playlist with 1.6K items, this results in lots of calls to
totalTracksDuration and remainingTracksDuration, slowing down start up and other operations
