v2024.2.6

Caution

Please see the known issues, updating to this version may cause setting loss! Use at your own risk.

Contains a pretty fundamental rewrite of camera matching logic to improve robustness. As such treat this release with a decent dose of paranoia and reach out with current run/journalctl logs if things are being weird.

We now match cameras in this priority order, with all cameras being matched by each strategy before trying the next:

• By physical usb port path and base name and USB VID/PID
• by physical usb port path and USB VID/PID
• By base name only (with a toggle switch in the networking card to disable this, and create a new VisionModule instead)

We also now give cscore the /dev/video/by-path camera path on Linux systems, pinning Photon USBCameras to a particular usb port once created instead of the video index (/dev/videoN).

Known issues

• Existing camera settings might not be properly matched on first boot, causing settings/calibrations to be lost in particular setups. Root cause here still under investigation

What's Changed

• Load libwinpthread-1.dll before libgcc_s_seh-1 by @mcm001 in #1228
• Actually properly match cameras by name fr this time by @mcm001 in #1237

v2024.1.4

CD thread

IMPORTANT
Releases 2024.1.1 through 2024.1.3 have been removed. There was a bug which caused the photonlib .jar file to be 10x its normal size.

The PhotonVision team is excited to announce the first full release for the 2024 FRC competition season! This beta cycle has been insane, with over 150 commits, 600+ files edited, and over 40,000 LOC modified in the main PhotonVision repo itself. Some of the major changes since 2023 include:

Reworked simulation support for Java and C++ featuring live camera view rendering and updated example projects
SQL-based settings database
Additional networking configurability, including arbitrary NT server location
Multi-tag pose estimation on-coprocessor
Improved camera calibration diagnostics
mrcal-enabled camera-calibration backend
Re-Enabled 36h11 tag support
Multi-camera support for identical USB cameras and CSI cameras
Raspberry Pi 5 supportPre-configured Orange Pi 5 image
Automatic Javadoc, Doxygen, and UI demo publishing
Usage reporting
Protobuf support for targeting results
Status LED support for Pi devices
Basic Python Support

Thank you!
