Romain Beauxis commented on LS-470:
-----------------------------------
Issue is most likely a gavl problem: it does not segfault when gavl is compiled
without sse support..
I need to write a minimal code to reproduce now..
> Segfault with gavl
> ------------------

> Key: LS-470
> URL: http://dev.sourcefabric.org/browse/LS-470
> Project: Liquidsoap
> Issue Type: Bug
> Components: Liquidsoap
> Affects Versions: 1.0
> Reporter: Romain Beauxis
> Assignee: Romain Beauxis
> Priority: Major
>
> I am experiencing a very weird segfault using gavl video converter..
> Here are the facts:
> * No problem with native converter
> * I have ruled out any stupid issue, printf'ing frame parameters, memseting
> 0 to frame pointer, checking planes size etc..
> * The issue only appears with the following parameter:
> liq frame size: 320x240
> picture size: between 340x340 and 360x360 (excluded)..
> I am not sure yet that this is an issue in liquidsoap..
