[vlc-devel] [PATCH] avcodec: disable threading by default

[Sergio M. Ammirata, Ph.D.]

People playing files should not be penalized for this bug. Wouldn't it
cripple the ability of many computers to decode h264 HD videos? That was
the biggest achievement of this multithreading feature.

Perhaps it can be dynamic based on the input type and the GUI can display
"Auto".
