[FFmpeg-user] FFMPEG build error due to MFX

[Dennis]

Hi all,

Having a problem building FFmpeg with QSV to run on Centos.
tried building mfx first, it demanded vaapi, which in turn needed dxorg,
and another 6-8 libs, got most through yum others built locally. Eventually
mfx configured and built without any errors.

FFmpeg v.2.7.2 with simple configure:  `PKG_CONFIG_PATH=/encoder/lib/pkgconfig
LDFLAGS=-L/encoder/lib CFLAGS=-I/encoder/include/ ./configure --prefix=/encoder
--enable-libmfx`

`make`
...

It seems like a MFX build error, but everything compiles and installs
fine...

Not sure if there should be a special  build instruction for MFX lib for
*NIX and for WIN32. As they seem different.

It'd be great if FFmpeg could support MFXLIB from Intel SDK as it builds
with one command with all its dependencies. https://trac.ffmpeg.org/ticket/
*4659*

If anyone has any word of advise, please share it.
