Я работаю над трехмерным музыкальным визуализатором, использующим Ogre3d, в основном это анализатор спектра, очень похожий на старый плагин xmms:
Работает хорошо, бары прорисовываются и обновляются, частоты кадров нетпроблемы, но он падает случайно.Иногда он может работать без проблем, закончить песню, в других случаях она мгновенно падает, иногда музыка просто останавливается без сбоев.
Вот исходный код основного класса:
https://github.com/balazsbela/OgreVisualizer/blob/master/src/VisualizerApplication.cpp#L221
Также сбои, кажется, случаются реже, когда я отображаю наложение частоты кадров из образцов Ogre.Поможет ли ограничение частоты кадров?
Сбои кажутся случайными.Это проблема с производительностью?
Пожалуйста, помогите мне, я совершенно заблудился, я также писал на форумах Ogre3d, но не получил ответов.

Спасибо.
