offload_rendering_client

Summary

offload_rendering_client receives encoded frames from the network, and uses a mix of NPPI and FFMPEG to decode the frames before updating the buffer pool. Setting the environment variable ILLIXR_USE_DEPTH_IMAGES to a non-zero value indicates that depth images are being received, and should thus also be decoded.

Note that there is a known color shift issue (to be fixed), where the decoded frame's colors are slightly different from the original frame (likely due to the many conversions between YUV and RGBA).
