systemvm/agent/noVNC/core/decoders/h264.js:1

• [nitpick] The new H264 decoder logic is substantial but lacks dedicated unit tests; consider adding tests to validate parsing, key-frame handling, and decoder configuration.

/*

systemvm/agent/noVNC/core/rfb.js:2560

• [nitpick] replaceAll is not supported in some older browsers; consider using textData = textData.replace(/\r\n/g, "\n"); for wider compatibility.

                    textData = textData.replaceAll("\r\n", "\n");

Changes doesn't seem to be working and require some investigation.

@weizhouapache @nvazquez let's also review if this creates any regression for keystore/keyboard related changes we had done.

looks good, will do some extra testing

[rohityadavcloud]

I've public rpm repo here for anyone wanting to try/test this https://build.yadav.cloud/cloudstack/pr/11119/el8/4.21/

[rohityadavcloud]

Tested noVNC 1.6.0 by manually applying the file changes to a ACS 4.20.1 env CPVM and restarting cloud service.

Post this, the noVNC 1.6 based console appeared slightly faster: (with VNC/TLS disabled)

novnc-1.6-upgrade.mov

Also tested the same env with noVNC 1.6 based console & VNC/TLS enabled:

novnc-1.6-with-tls.mov

[DaanHoogland]

I think we should go ahead with this PR but,

• in xen special keys get very confused if you break connection to the console and re-attach
• in vmware special keys get broken if you break connection to the console and re-attach
• in kvm I could switch between local keyboard and screen settings with no problem

If I don't touch i can reverse the shift-lock by closing the connection and creating a new one. The rest of the console will keep working but shiftlock will be reversed.

LGTM, manually checked it could not find any regressions

@vishesh92 @borisstoyanov @sureshanaparti , I marked this waiting-for-smoketest-results but actually think it is not going to give us extra information about the changes here. merging.
