Auto DJ Fails in win10-64

[Peter Burg]

Leaving the app overnight broadcasting, I twice noticed Mixx hangs without playing.
One player loaded, the other one empty.
mixxx-2.4.0-alpha-pre-master-git7498-release-x64

[Daniel Schürmann (daschuer)]

Which transition mode did you use? With which time?
Did you define into and outro regions?

Can you recall which two track where affected?

Please attache the mixxx.log file from this session.
https://github.com/mixxxdj/mixxx/wiki/Finding-the-mixxx.log-file
by luck it is still there with a suffix number.

Hi Daniel,

transition; Fade at Outro Start, 4 sec
defined; intro start, outro start and outro end.(most tracks)

I see in the log section there are 3 minidumps (with mixxx-settins) so there were 3 instances with malfunctions.

Now playing vs.7491, playing well:-)

@wunjo Please let us know if you encouter that bug again and provide a backtrace in case Mixxx crashes.

[Peter Burg (wunjo)]

Hi Ronso0,

Still happens here. Still using mixxx-2.4.0-alpha-pre-master-git7491-release-x64 for broadcast.
Mixxx didn't crash it just stopped the autoDJ for some reason.

From time to time I tried newer versions of 2.4 alpha, they didn't work for me, same story.
These include:
Mixxx-main-r7730-b7e72bf826.msi
Mixxx-main-r7786-eff873a190.msi
Mixxx-main-r7803-f1c2947989.msi
Mixxx-2.3-r8090-9f259f8fef.msi

Win10 20h2 64
AMD A8-3870 APU with Radeon(tm) 8Gb
I run Mixxx in developer mode due transfer from A=440 to A=432

[ronso0 (ronso0)]

hmm.. So playback stops but AutoDj still appears to be engaged?

[Jan Holthuis (holthuis-jan)]

Please post log output, maybe AutoDJ encountered some debug assertion and disabled itself.

[Jan Holthuis (holthuis-jan)]

Hmm, or maybe not. DEBUG_ASSERT does show up in the logs, not just on the terminal, right?

Does it always happen for the same track?

[Peter Burg (wunjo)]

Jan, no, at random.

Logic tells me it is caused by a change between mixxx-2.4.0-alpha-pre-master-git7491-release-x64.exe witch runs 7/24, and mixxx-2.4.0-alpha-pre-master-git7498-release-x64.exe where the stops occur.

last try log

[Peter Burg (wunjo)]

also last try

[Daniel Schürmann (daschuer)]

Does this still happen? There is no violated assertion visible in your logs.

I have prepared a Mixxx version with more debug output when using auto DJ.
Can you please try to reproduce the issue with the build found at the bottom of this page?

Hi Daniel,

I'm using now the standard edition 2.3.1
No problems sudden stops now.
The only problem now is Mixxx sometimes skipping the fade out, after changing the fade out in the next track. But i have to rapport this as a new bug, I guess..

I will try the prepared version, report back on it.

The jump cut issue is already tracked here:

[Daniel Schürmann (daschuer)]

I have prepared here another build with more debug messages and merged with 2.4
The original link was 2.3 based.

I am curious if this issue is a 2.4 regression.
The main difference is that we have replaced the sample based cue point API by a frame based one.
Maybe there is a factor 2 missing somewhere.

[Peter Burg (wunjo)]

Daniel,
The download on the link you provided on 27-2 has no issues. Runs now 55 hours.
I'll check on the other bug report 1948975
Thanks
