Apparently some iPad browsers were having their local webcam freeze
after a window.confirm prompt was shown. This replaces all uses of
window.confirm/window.alert with an in-app modal.
When the Safari browser puts a webcam video full-screen and then
returns, the z-index of the video was higher than the buttons and
controls normally overlaid on top of it.
Add a z-index:1 to the video controls to keep them on top after
returning from full screen. Similar: for popped-out draggable videos,
adding a z-index:1 allows the video to correctly sit on top of docked
videos without the docked video controls (zi:1) rendering above the
popped-out video when you overlap them.
Note: the z-index:1 is applied to popped-out and video controls, any
other combination (e.g. 1 for popped-out and 2 for controls) caused
controls of docked videos to render on top of popped-out ones when they
overlapped.
* Add local detection for users who are broadcasting dark (e.g. mostly
or completely black) video feeds from their local device.
* Every 5 seconds while the webcam is active, the average RGB color is
sampled. If the average color value remains below 60 (out of 255) for
two consecutive samples, the camera is stopped automatically.
Add moderation rules:
* You can apply rules in the settings.toml to enforce moderator restrictions on
certain users, e.g. to force their camera to always be NSFW or bar them from
sharing their webcam at all anymore.
Chat UI improvements around users blocking admin accounts:
* When a main website block is in place, the DMs button in the Who List shows
as greyed out with a cross through, as if that user had closed their DMs.
* Admin users are always able to watch the camera of people who have blocked
them. The broadcaster is not notified about the watch.
New operator commands:
* /cut username: to tell a user to turn off their webcam.
* /unmute-all: to lift all mutes on your side, e.g. so your moderator chatbot
can still see public messages from users who have blocked it.
* /help-advanced: moved the more dangerous admin command documentation here.
Miscellaneous fixes:
* The admin commands now tolerate an @ prefix in front of usernames.
* The /nsfw command won't fire unless the user's camera is actually active and
not marked as explicit.
* WebRTC functionality is now 100% working as intended for Safari and
iPad browsers!
* The legacy WebRTC API had properties like offerToReceiveVideo
available on createOffer(), to set up a receive-only channel, but the
modern WebRTC API had removed these and Safari only supports the
modern API.
* The modern solution for the same feature is to add a recvonly
transceiver to the connection in place of offering a local video/audio
stream to share.
* Add support for storing DM history between users in a SQLite3 database.
* Opt-in by editing your settings.toml to set DirectMessageHistory/Enabled=true
* Retention days (default 90) will flush old DMs on app startup.
* On the front-end, DM history is checked when a DM thread is opened.
* Try a new strategy to get Apple (iPad/iPhone) webcams to connect.
* "Apple compatibility mode" setting: on by default if iPad/iPhone is
detected or can be opted into in the chat settings Misc tab.
* In Apple compat mode: when you open someone else's webcam, you always
attach your local video on the WebRTC offer. This would normally make
your video auto-open on the remote side, but the previous commit
updates the chat page to ignore offered video if you did not opt-in to
auto-open your viewer's camera.
* This should satisfy the two-way video call limitation in Safari: the
iPad always shares its video and gets video from the person they are
watching.
* If the person they are watching did not auto-open your video: they
ignore the attached video on your offer and don't display it.
* The /ban command doesn't require the target user to be online at the
time of the ban.
* Update the presence messages so they will generally only go to the
primary (first) public channel, and also to another public channel if
the user is currently looking at one of the others.
