[oi-dev] libjpeg-turbo and VLC

[Aurélien Larcher]

Hi,
we were thinking about choosing a default implementation for all the
components.
As it seems as been done one libjpeg-turbo to address some of your
concerns, that some opensource components rely on libjpeg-turbo functions
that are not part of the JPEG API and that major Linux distributions like
Debian and Fedora migrated to this implementation it would not be illogical
to do the same.
In any case we should still provide IJG's reference implementation.
Regards

Aurelien
