Blending two NV12 frames.

Hi All,

I'm trying to blend two nv12 files. I'm Using sample code from https://software.intel.com/en-us/forums/intel-media-sdk/topic/536779 post.

I'm using one 1920x1080 yuv file and another one is 720x576. Blending of Luma appears fine, where as colors are scattered as 4 quadrants.

Attaching modified code as well.

Hi Hamza, 

Can you please share more details about your system configuration like OS, hardware etc. Also, can you verify and confirm if latest version of MediaSDK/Media Server studio installed on your machine? 

Thanks,

Hi Harsh,

I'm using E3-1245 v5, with centos-release-7-2.1511.el7 64-bit.

Yes i'm running latest version of MediaSDK and I'm able to blend the same two files using MediaSamples_Linux_2016. Did you have a chance to run the attached code in your set-up ?

Hi Harsh,

There was an issue in utils that i was using. It was reading nv12 files as yv12. Blending is fine after fixing that.
