Patch to only build NV16 if Orc is available (1.45 KB, patch)

Description Brendan Long 2013-05-15 16:54:54 UTC 
When I try to build gst-plugins-base from git, I get:

  CC     libgstvideo_1.0_la-video-format.lo
video-format.c: In function 'unpack_NV16':
video-format.c:930:3: error: implicit declaration of function 'video_orc_unpack_NV16' [-Werror=implicit-function-declaration]
video-format.c:930:3: error: nested extern declaration of 'video_orc_unpack_NV16' [-Werror=nested-externs]
video-format.c: In function 'pack_NV16':
video-format.c:940:3: error: implicit declaration of function 'video_orc_pack_NV16' [-Werror=implicit-function-declaration]
video-format.c:940:3: error: nested extern declaration of 'video_orc_pack_NV16' [-Werror=nested-externs]
cc1: all warnings being treated as errors

Even though in the configure step, it says it won't build orc:

configure: *** Orc acceleration disabled.  Requires Orc >= 0.4.17, which was
               not found.  Slower code paths will be used.

I narrowed the problem down to commit af24e238802112ae7072a8246a05c5df2ccfcc7c (https://bugzilla.gnome.org/show_bug.cgi?id=700377). I can build with the previous commit (74a31a02fc6b2d6cba91765e6bc62525fa9bffb5).

Patch to only build NV16 if Orc is available

This fixes it for me, but I can't test it with Orc, since I'm on Ubuntu 12.04 (Orc package is too old).
Comment 2 Tim-Philipp Müller 2013-05-15 17:22:31 UTC 
This should fix it:
