| Summary | 0008900: Crashing bug with RubberBandStretcher | ||||
| Description | I've been following up a bug report on the MB forum. It's a very reproducible crash on Windows (both for my MSVC build and also Robin's gcc build) but I haven't had a chance yet to try it with Ardour. Also, it probably needs testing with the other platforms. | ||||
| Steps To Reproduce | 1) In the Cues page, select any clip and enable its 'Stretch' mode. 2) Press its "/2" button more than twice. 3) Attempting to replay the clip now causes Mixbus to crash. | ||||
| Additional Information | I tracked the crash down to some code in librubberband. Intentionally or otherwise, it seems like RubberBandStretcher must have a limit on how much a clip can be speeded up. Double speed works okay and x4 works okay but x8 will crash MB in about 80% of cases. | ||||

Steps to reproduce: 1) In the Cues page, select any clip and enable its 'Stretch' mode. 2) Press its "/2" button more than twice. 3) Attempting to replay the clip now causes Mixbus to crash. Additional Information: it seems like RubberBandStretcher must have a limit on how much a clip can be speeded up. If this can't be fixed, maybe there could be an upper limit on the maximum speed? (i.e. an upper limit on the number of '/2' presses...) |

FWIW I can reproduce the same crash in Linux but with a couple of minor differences... on Linux, the speeded-up clip will attempt to play for a second or so (apparently at the last known working speed) and then I see the same crash. And so far in Linux, the crash rate is 100%. |
|
|
Does anyone know this got fixed? I haven't tried Linux yet but I can't reproduce it in Mixbus Windows any more... |

Dunno but just happen to stumble over https://github.com/Ardour/ardour/commit/fcbe6aab494bf4e13b9ad3d4d5e0ff60ce65626c recently and it sounds related enough. |

Something's definitely improved this because it used to crash with any clip - but now, I can only find one clip that crashes, namely:- Under Goldbaby Audio Loops->Loops->PercAndDrums and it's the clip called "HandsAndFeet1.flac" |

This no longer seems to be reproduceable (here, at least). |
