VPP Sample works with Intel® Media SDK (hereinafter referred to as "SDK").
It demonstrates how to use the SDK API to create a simple console application that performs video processing of raw video sequences.
VPP Sample supports the following video formats:
| Format type | |
|---|---|
| input (uncompressed) | NV12, YV12, YUY2, RGB3, RGB4, IMC3, YUV400, YUV411, YUV422h, YUV422v, YUV444, UYVY, AYUV, Y210, Y410 |
| output (uncompressed) | NV12, YUY2, RGB4, YV12, AYUV, Y210, Y410 |

width=720
height=480
cropx=0
cropy=0
cropw=720
croph=480
dstx=0
dsty=0

Please, also pay attention on “Running the Software” section of <installfolder>/Media_Samples_Guide.md document where you will find important notes on backend specific usage (drm and x11).
-
Streams composition works only on the Intel® Xeon® processor E3-1200 v3 product family with hardware SDK library.
-
Output cropping may be ignored in streams composition for now.
-
Sample may not function properly on systems that have a non-Intel VGA controller as the first (primary) because Intel device is not first in the list.
To workaround this issue, swap names of DRI device files:
$ cd /dev && mv card0 tmp && mv card1 card0 && mv tmp card1and do the same for the files
