Hi,
This patch is based on the original work done by Timo Rothenpieler, and his
patch for static linking with libnpp:
[http://ffmpeg.org/pipermail/ffmpeg-devel/2016-June/195078.html](https://ffmpeg.org/pipermail/ffmpeg-devel/2016-June/195078.html)
Based in my recomendations now it's possible to link directly to libnpp*
libraries without linking to the CUDA SDK:
[http://trac.ffmpeg.org/ticket/6405](https://trac.ffmpeg.org/ticket/6405)
http://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=2d978d1c721ae69a9007b530153067736d4ddc79
Then I created an updated version of the patch.
By default the linking is the regular dynamic link (aka
"--disable-libnpp-static" config).
However, if you like to compile statically with "libnpp*_static.a" then add
these parameters:
$ configure ... --enable-nonfree --enable-libnpp --enable-libnpp-static
--enable-cuda --extra-cflags="-I/usr/local/cuda/include/"
--extra-ldflags="-L/usr/local/cuda/lib64/"
This assumes the CUDA SDK is installed in "/usr/local/cuda".
Regards.
A.H.
