Working in tethered mode?
Hey All, We're trying to develop a commercial application that will eventually run on PC (requires high-level graphics) and want to use a Meta Quest Pro as an HMD (using USB tethering). I'm seeing that the connection is possible but recommended in the docs for development only. Is it possible for production uses also? Also, when using the Quest Link software on my PC, the rendering is SUPER slow, and in Task Manager, the OVRServer takes ~60% of GPU. How can this be fixed? My specs are: - Intel Core i9-10885H CPU - 32GB RAM - NVidia RTX 2070 Max-Q GPU
Quest Link USB3 transmit latency significantly higher on Quest Pro
Hey all, I recently got a Quest Pro (and shortly after, a Quest 2) and being the stubborn person that I am, decided to try writing an OpenXR driver for Quest Link to use on macOS and Linux, since Meta does not currently support these platforms (nor do I expect them to any time soon lol). However while writing my own driver, I noticed that the Quest Pro consistently had worse performance. Looking further, I found that with the exact same resolution, encoding settings, etc, Quest 2's USB transmit is a stable 0.5ms, whereas the Quest Pro often crosses the 1ms transmit time. Quest 2: INFO [comp_ql_calc_frame_pacing] Avg: tx 0.575194ms, encode 18.336222ms INFO [comp_ql_calc_frame_pacing] Avg: tx 0.479831ms, encode 18.421983ms INFO [comp_ql_calc_frame_pacing] Avg: tx 0.482888ms, encode 18.347163ms INFO [comp_ql_calc_frame_pacing] Avg: tx 0.480982ms, encode 18.464094ms Quest Pro: INFO [comp_ql_calc_frame_pacing] Avg: tx 1.075382ms, encode 12.934615ms INFO [comp_ql_calc_frame_pacing] Avg: tx 0.710841ms, encode 10.299981ms INFO [comp_ql_calc_frame_pacing] Avg: tx 0.850958ms, encode 10.371938ms INFO [comp_ql_calc_frame_pacing] Avg: tx 0.645109ms, encode 10.543258ms INFO [comp_ql_calc_frame_pacing] Avg: tx 0.592482ms, encode 10.271824ms INFO [comp_ql_calc_frame_pacing] Avg: tx 0.770167ms, encode 10.140699ms INFO [comp_ql_calc_frame_pacing] Avg: tx 0.911711ms, encode 10.275272ms INFO [comp_ql_calc_frame_pacing] Avg: tx 0.556561ms, encode 10.065738ms Both devices are on v47, and `libusb_get_device_speed` returns `LIBUSB_SPEED_SUPER` for both headsets, so in theory they should be operating at 5000Mbit/s. It's worth noting that I'm including the cap'n proto preamble packets, so that's 0.4ms Quest 2/1ms Quest Pro across 3-4 packets (segment sizes + cap'n proto + optional csd + idr/coded slices).
SDK for playing videos from PC on Oculus Rift CV1?
Oculus noob here. I see a lot of apps for the Rift that can play videos from a PC on the Rift (examples: https://www.oculus.com/experiences/rift/1211180398923002/ , https://www.oculus.com/experiences/rift/1004289456346194/ , and https://www.oculus.com/experiences/gear-vr/1256687334386627/ . What SDK (or part of SDK) exactly is needed to create an app like this? Can the video be streamed to Rift through USB or another wired connection except HDMI? Using the same SDK, would I be able to play a live-stream generated from my PC on the Rift?
