Bug#892014: gstreamer-vaapi: FTBFS on 32-bit archs

[Steve Langasek]

Package: gstreamer-vaapi
Version: 1.13.1-1
Severity: serious
Tags: patch
User: ubuntu-devel at lists.ubuntu.com
Usertags: origin-ubuntu bionic ubuntu-patch

Dear maintainers,

gstreamer-vaapi in experimental is failing to build on all 32-bit archs
because of a type mismatch.  Please find attached a patch which fixes this
build failure.

+Description: Fix 32-bit compatibility with libva
+ gstreamer-vaapi is using a pointer to an unsigned long where the API
+ specifies a pointer to a uintptr_t.  This works ok on 64-bit architectures,
+ but on 32-bit the sizes are different and gives a build failure.
