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
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
