Add example to show libva buffer sharing with extension clCreateImageFromLibvaIntel.
This example reads a source nv12 file to a VASurface, and creates a
target
VASurface. Then creates corresponding cl image objects from them. After
using ocl to do mirror effect post-processing on source VASurface,
target
VASurface is shown on screen by default.
Code of loading nv12 file to VASurface are referenced from
libva/test/encode/avcenc.c.
v2:
Delete 1920x1080.nv12 and 640x480.nv12 because of large size, add
256_128.nv12 as default test image.
v3:
1. Re-org files: add libva as a submodule then use display related
files.
2. Show result on screen by default instead of saving as a file.
3. Fix warnings.
v4: Fix whitespace format warnings.
v5:
1. Modify upload_nv12_to_surface to read a nv12 file and then upload
it to an NV12 VASurface. Also modify store_surface_to_nv12.
2. Change the cl post-processing kernel from gray effect to mirror
effect, which make demo cooler.
3. Minor fix of other problems.
v6: Remove unnecessary OUTPUT_NV12_DEFAULT related code.
