ffmpeg pkgconfig deps broken, it would appear

[Rex Dieter]

Trying to respin xine-lib:

checking for FFMPEG... configure: error: Package requirements 
(libavcodec >= 51.20.0) were not met:

Package libraw1394 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libraw1394.pc'
to the PKG_CONFIG_PATH environment variable
Package 'libraw1394', required by 'libavcodec', not found
