Crash after unpausing with ALSA plugin

[jieweix]

DeaDBeeF almost always exits automatically when resuming playing paused track.

Deadbeef version: 1.9.1
OS: Ubuntu 22.04.1 LTS

[Oleksiy-Yakovenko]

Could you please check whether current master / 1.9.2-beta1 has the same problem? I have a reason to believe this issue existed, but is now already fixed.

[jieweix]

For some reason, I cannot launch DeaDBeeF after building from the current master

[Oleksiy-Yakovenko]

A build can be downloaded, instead of building locally:
https://sourceforge.net/projects/deadbeef/files/travis/linux/master/deadbeef-static-devel-1-x86_64.pkg.tar.xz/download

[jieweix]

Thank you. I used this instead and the problem didn't occur (slight scratching sound and break though), but when I copy the Musical Spectrum plugin into plugins/ (ddb_vis_musical_spectrum_GTK2.so and ddb_vis_musical_spectrum_GTK3.so) the problem occurred again. Then I moved the two files from the current plugins folder (/usr/lib/deadbeef) and 1.9.1 also didn't have the problem again (still a slight break after resuming). So I assume there's a problem with the Musical Spectrum plugin?

[jieweix]

I then tried configuring the Musical Spectrum plugin after moving it back, lowering the FFT size, and it kind of worked, the exiting after resuming didn't occur, but the "slight" break after resuming became even worse, which is acceptable compared with exiting but still a bit annoying. Anyway, my troubleshooting concludes that this is not an issue with DeaDBeeF itself but with a plugin.

[Oleksiy-Yakovenko]

Thank you. I used this instead

oh, yes, sorry -- I meant to post this link, but copied arch linux package instead. That's the correct one.

when I copy the Musical Spectrum plugin into plugins/ (ddb_vis_musical_spectrum_GTK2.so and ddb_vis_musical_spectrum_GTK3.so) the problem occurred again.

hmm.. ok, I'll try to install musical spectrum plugin and see if I'll find what's causing the crash.

[Oleksiy-Yakovenko]

I installed the latest build from master, and the latest waveform seekbar plugin, then added the waveform seekbar using design mode.

No matter how hard I tried, I could not make any quits / crashes after pausing, unpausing and restarting the player.

Is there anything else in your deadbeef settings? Is there any chance for you to provide crash log?

[Oleksiy-Yakovenko]

oh damn.. I just realized I was trying with the wrong plugin.
Getting musical spectrum now.

[Oleksiy-Yakovenko]

Still no luck, same with musical spectrum -- no quits or crashes, either when using pause key, or when resuming track on startup.

[jieweix]

Could you try setting the FFT size to 16384 samples, which is my configuration when the issue would occur?

[Oleksiy-Yakovenko]

I can't set it to 16384, since the plugin seems to have a maximum set to 8192

[Oleksiy-Yakovenko]

oh, nevermind.. it works if I use the + and - buttons, but not when I enter the number directly. trying now.

[Oleksiy-Yakovenko]

It does crash, seems like a bug in the musical spectrum plugin.
Here's the backtrace:

Yeah, the following is my log, crash happens at "Segmentation Fault".

@oldrust Hi there

• You have posted your crash log in a closed bug -- it has been fixed in the 1.9.2 that has been released a few days ago.
• If your problem still occurs in 1.9.2 - please post a new bug report.
