Mixxx crashes when analysing a number of Mp3 files

[xyligo]

Seems to happen after a while of analysing files (Around 7400 total). Sometimes will pop up an "out of memory" or "insuffiecient memory to generate a report" error on restart.

If you need any more details, let me know.

Sounds like a memory leak, either in the VAMP code or somewhere else. One option would be to upgrade to the latest VAMP SDK and plugin versions.

VAMP SDK: 2.3 -> 2.6
http://www.vamp-plugins.org/develop.html

VAMP QM Plugins: ?.? -> 1.7.1
https://code.soundsoftware.ac.uk/projects/qm-vamp-plugins/files

[Daniel Schürmann (daschuer)]

Do we have a hint that this crasher reported here is probably fixed with the new VAMP version?

[Uwe Klotz (uklotzde-deactivatedaccount)]

from the Vamp plugin SDK CHANGELOG

Version 2.4, 2012-07-12 (maintenance and minor feature release):

  * Fix thread-safety issue in PluginInputDomainAdapter

[Daniel Schürmann (daschuer)]

Yes! Thanks

[Uwe Klotz (uklotzde-deactivatedaccount)]

Hopefully fixed with the new VAMP SDK version
