Unlock BPM of full library doesn't work

[RafaelFrance]

Bug Description

Start situation : some tracks of the library have BPM locked (not all).

Select the full library with Ctrl+A.
Unlocking : Adjust BPM/Unlock BPM
A progress window opens, but closed at around 15-30%.
Some tracks stay locked.

The progress windows of unlock doesn't show the number of tracks (has I can see when I lock a small number of track). It shows " % n tracks"

Unlock BPM works when selecting individual tracks or an area of several tracks.

Version

2.4.0

OS

Ubuntu 22.04

So this is about unlocking via the track menu?

[ronso0]

In which view? Tracks?

[RafaelFrance]

Yes, in Tracks list (view).

Tango skin.

If you can reproduce this, please attach the log. That may reveal the reason the batch op was aborted.

A progress window opens, but closed at around 15-30%.
Some tracks stay locked.

Are "some tracks" the remainders (~70 %)?

[ronso0]

I could somehow reproduce this:

• test library with 16k tracks, some have BPM, most don't
• go to Tracks, mark all tracks
• track menu -> BPM -> Lock BPM
• (progress dialog okay, takes some time)
• = all tracks locked, regardless of BPM

The reverse however fails, or rather there is an issue with the tracks view:

• mark all tracks, BPM -> Unlock BPM
• (batch task seems to finish successfully)
• issue with all many tracks with no BPM:
  • all rows show the Lock icon, however when selecting the library row the icon is Unlocked
    (only true for the initially selected row, i.e. for a selection range all other selected rows are still shown as Locked)
  • track menu -> BPM offers only "Lock BPM"
• issue persists across restarts

Then

• load an affected track to a deck OR menu -> Analyze -> Re-analyze
• as soon as BPM track analysis starts (indicates BPM are not locked) the lock icon is now correct (= unlocked)

I'll take a look.

My Library is around 7600 tracks.
Only 109 tracks on a Playlist have (all 109 tracks) BPM locked.
Video shows when I tried (and failed) to unblock all tracks of the Library.

Note : I use BPM lock to visual organization of my tracks, lick colors. BPM are mainly imported from Metadata of files.

[ronso0]

Could you please verify:
if all tracks have been analyzed (do batch analysis via the Analyze feature (sidebar)) lock/unlock works for all tracks?

[RafaelFrance]

Tracks as they are today (BPM are mainly imported from Metadata of files)

• Analyse of tracks (7636) (batch analysis via the Analyze feature (sidebar))
• lock all Tracks (7636). Problem : the progress windows stop before the end of process. A lot of Tracks are not locked.
• I found two Track where I can not unclock BPM manualy. I Hide these two Tracks.
• Lock all tracks (7634). Problem : the progress windows stop before the end of process. A lot of Tracks are not locked.
• Unlock all tracks (7634). Seems to work (because few tracks locked ?).
• All Tracks selected (7634) / Reset / BPM and Beatgrid. Problem : the progress windows stop before the end of process. A lot of Tracks are not reset.

Not sure but progress windows seems to stop always between 20% and 30%

[ronso0]

I found two Track where I can not unclock BPM manualy. I Hide these two Tracks.

(I suggest you make a backup of your library so you can retest with thi state later on)
Please run Mixxx from the command line, note the logged lines when you attempt to lock/unlock these two tracks and post them here.

[RafaelFrance]

In a crate wiht the 2 tracks (with problem)
Initial : the tracks are locked.

Unlock of all

• doesn't work.
• no logged line.

Unlock manualy (with mouse click on icon)

• doesn't work.
• no logged line.

Load track 1 on Desk
warning [AnalyzerThread 0 #1] SoundSourceMp3 - Reading MP3 data with different sample rate 48000 Hz <> 44100 Hz - aborting
warning [AnalyzerThread 0 #1] AudioSource - Failed to read sample frames: expected = [221184 -> 225280) , actual = [221184 -> 222336)

Load the track 2 on Desk
warning [Main] Track duration has changed since last analysis 1904 != 1921
warning [CachingReaderWorker 1] First sound has been moved! The beatgrid and other annotations are no longer valid "file:///Datas/Musiques/Silence3s.mp3"

Note: I see that these two track are "special".

• track 1 : duration 4:16, but a waveform of only 5 seconds. After it is a straight line on the waveform.
• track 2 : duration 3 seconds.

[ronso0]

So the root cause is broken audio files?

Can you lock/unlock after resetting BPM, beatgrid and waveform for those two tracks?
