I'm looking for a way to use VPP with extra parameters changing by every frame.
I builded media SDK sample projects (sample_transcode & sample_vpp). so now I can use sample transcoder with sample VPP dll.
Then I'd like to add controll parameters to VPP(e.g. some threshold values for image process).
Is there any way to achive this?
You can add extra control parameters to the samples by opening up the projects, adding changes to the parameter parsing and initialization sections, and rebuilding.
However, the tutorials are probably an easier route to understand how the VPP code works. You can get them here. https://software.intel.com/en-us/articles/media-sdk-tutorials-for-client-and-server.
Note that some parameters can only be passed in with extended parameter buffers. You can find simple examples of this in the tutorials.
