BrightSignOS Updates & Release Notes

Feature Changes

• OS-15494: (General) QtWebEngine is not available for Chromium versions above 87 (meaning WebRTC desktop sharing is no longer supported)

• OS-21652: (General) Fixed a Chromium bug that can cause webpages with a page containing @starting-style in the stylesheet to crash
• OS-21708: (General) Fixed handling of large PES packets in MPEG transport streams that would cause rebuffering, stream restarts and loss of sync.

Supervisor v3.3.4.1 Update (OS-21701)

• BCN-21349: Error handling for display firmware update process
• BCN-21366: Check if FW file is completely uploaded before reboot or triggering tv-controller service

Improvements

• OS-17808: (LGUV5N) Added crash dump support
• OS-21399: (Series 5 and 6) A new option, DropErrorFrames was added to roVideoPlayer and the HTML video tag. This allows users to configure whether to show frames with errors or drop them (which can cause pauses). By default, these errors are shown on Series 4 and earlier players. On Series 5 and later players, errors are hidden by default.

Bug Fixes

• OS-20573: (General) Fixed poor rendering performance for video in HTML presentations on rotated screens. This issue was intermittent and occurred from start-up; it was introduced in BOS 9.0.168.2 but the failure rate was much higher in versions from 9.0.211 on.
• OS-21094: (General) SetAudioMode(0) can result in no audio if the audio routing set has no valid route for multichannel output. This restores the previous behavior which will do stereo mixdown as a last option.
• OS-21496: (General) JavaScript legacy BSObjects will now receive events when run in nested iframes
• OS-21519: (General) Fixed a JavaScript object construction issue that could result in the error ReferenceError: Cannot access 'objectDefinition before initialization

Bug Fixes

• These roDeviceInfo methods have been deprecated:

• OS-19567: (LS5) Fixed a bug where interlaced videos were de-interlaced, but only showed every other frame; this also sometimes led to jittery playback.
