Waltham renderer The waltham renderer creates a buffer to be transmitted to other domain. The current implementation it uses gstreamer. You can use gstreamer pipeline as you want by configuraing from "pipeline.cfg". This file should be in the folder "/etc/xdg/weston/". As an example, please refer to the example file named "pipeline_example*.cfg". -pipeline_example_general.cfg : Does not use any HW encoder. -pipeline_example_intel.cfg : Use Intel's HW encoder. -pipeline_example_rcar.cfg : Use Rcar's HW encoder. Rename file as "pipeline.cfg" and put in correct place when you use them.
