I don't know if PV has this as a bug or an intentional feature that hurts my application.

I want to use the PV output stream http://localhost:1182/stream.mjpg as input to another program. [Since there might still be some interest in the CALIB Pose Guidance program I thought I'd start resolving the huge number of merge conflicts by interfacing Calibration Pose Guidance with PV instead of trying to integrate the Guidance. That could be good enough to be useful.]

My camera is set in PV at 1280x800 resolution and I start the PV calibration at the 1280x800 resolution. Unfortunately as soon as I start the PV calibration the PV output stream on port 1182 flips from the correct 1280x800 to a new incorrect (for my purposes) 640x400.

Was this reduction of resolution during PV calibration intentional or accidental? Could PV be changed to retain the port 1182 resolution the same as the user specified resolution?
Thanks.

Reduced resolution during calibration is the least of my problems. Turns out PV has no pure raw camera stream - cross-hairs are added - and even that modified "raw" stream is disabled during calibration and unavailable for use. The processed stream has the marker IDs added. Without some changes to PV the pose guidance cannot be interfaced to PV. I'm sorry I didn't test this idea properly before making an issue. Interfacing pose guidance to LimeLight does work well as the actual, raw camera stream is always available.

Larger scope of issue than I expected.
