Add support for libav api as it sligthly differ.

[scarabeusiv]

The libav use micro version as 0
The ffmpeg use the micro version as 100+

Simply check if the variable is defined then it is not libav.

This is something that's already being worked on. See #629.

Thanks anyway.

Well I saw it, but it is completely broken so I wrote it from scratch. I was not aware if there is any way how to attach other commits to other owner merge request.

[elupus]

Hold off on stuff like this until we have https://github.com/elupus/xbmc/tree/ffmpeg_0.10.2 merged.

[scarabeusiv]

Well this is relevant even after the 0.10.2 api merge because libav and ffmpeg will probably differ there forever.

Also as distro packager I would love to see this in eden where the 0.10.2 branch won't prolly end :)

[amejia1]

@scarabeusiv Which distro do you work with?

Also, this doesn't address the issue with properly checking for vdpau support in libav. The symbols from libav used to check for vdpau support are no longer exported with libav-0.8.

As elupus said, hold off on this until his pull request is merged. If you want to help, provide your feedback in PR #629.

@amejia1 Gentoo like Alexis, but i work on libav and he on ffmpeg :)

Hmm you are right I didn't address the vdpau check part as we export the ac_blabla=yes to be always sattisfied as it is handled by our USE depencencies with no need for the configure script to actually look for it.

So lets wait on th emerge of the 0.8 api (0.10.2 how you would call it) and I will see which patches I will be needing there :)
