Increased Latency in PV Video Streaming When Deployed as Unity Plugin

[xli149]

Hello, thank you very much for being able to provide us with such a great open-source project. After installing the appxbundle on Hololens 2, I can successfully access PV video streaming, and the latency is relatively low. However, when I deploy it as a Unity plugin, I find that the latency of PV video streaming increases significantly, to about 1 second. Why is this happening? Is there any way to reduce latency?

Best Regards

Hello,
We believe this happens because running Unity + 1080p video compression is too demanding for the HoloLens hardware.
A possible workaround is to reduce PV resolution and/or framerate.

Thank you very much for your reply. If it's convenient, could you please let me know specifically which part of the code should be modified? I haven't found the location to adjust the resolution yet.

See client_stream_pv.py lines 32-35 and 79.
Supported resolutions and framerates are in pv_configurations.txt.
