Thanks for pointing this out. Fortunately I haven't lost the file, here it is.
> Several bugs when testing a (very dumb) videoconference example
> ---------------------------------------------------------------
>
> Key: LS-623
> URL: http://dev.sourcefabric.org/browse/LS-623
> Project: Liquidsoap
> Issue Type: Bug
> Reporter: David Baelde
> Assignee: Romain Beauxis
> Attachments: videoconf.liq
>
>
> I have attached a script that demonstrates a simple high latency video
> conference system using only liquidsoap: each party sends one stream using
> output.harbor() and receives another one using input.http().
> Without gavl, it does not segfault, but the video inputs fail to decode any
> data. It gets a little better (sometimes) if catch more errors in
> ogg_decoder.ml.
> With gavl enabled, this segfaults rather quickly, with this kind of backtrace:
> 0xb760524e in yuvj_420_p_to_rgba_32_mmx (ctx=0x855a138) at
> ../csp_planar_packed.h:101
> 101 ../csp_planar_packed.h: No such file or directory.
> in ../csp_planar_packed.h
