This beta will be the last one before the release of 3.0.0, unless some big error is found.
The release focuses on stability improvements and polishing of existing features.
Some new features are also included.

New documentation chapters have also been added which aims to explain how recordings and Viseron in general is working.
New sections will be added in the future to highlight common usecases.

Breaking changes

• The /recordings folder is no longer used, and should be replaced with the /event_clips folder.
  This namechange was made in order to clear up some confusion on what this folder is storing in v3.
  Docker instructions have been updated: https://dev--viseron.netlify.app/docs/documentation/installation#running-viseron
• trigger_recorder has been deprecated in favor of trigger_event_recording

New features

• Faces to recognize can now be pulled from Compreface directly
• A logfile is now created in the config directory. Docs have been updated accordingly: https://dev--viseron.netlify.app/components-explorer/components/logger#view-logs
• You can now download events and snapshots from the Events page.
  You can also specify a timespan for 24/7 recordings which will be downloaded as an MP4 file.
  Documentation can be found here: https://dev--viseron.netlify.app/docs/documentation/configuration/recordings#downloading-recordings
• New config option record_only which makes it possible to create continuous recordings without running any type of detectors.
• New config option width and height for still_image which allows setting the resolution of the still image
• You can now click individual events in the popup windows on the Events/timeline view to seek to the event
• New telegram component provided by @smelis, which allows sending of clips and thumbnails using Telegram.
• New ptz component provided by @smelis, which can be used by the Telegram component to control a camera.
  The PTZ functionality will be ported to the web UI as well at some point.

Full Changelog: v3.0.0b12...v3.0.0b13

This release includes a multitude of fixes and changes to improve the stability of Viseron.
It also adds multiple clean up jobs to keep the database and filesystem in sync in case of any crashes.

If you have tried the v3 beta before and experienced issues, i highly suggest trying this release out since it contains loads of fixes.

Fixes

• Remove volumes from the Dockerfile to avoid issues with bind mounts
• Use the process watchdog for Darknet so that it is restarted in case of crashes
• Add extra logging to shutdown procedure to pinpoint threads and processes that is slowing it down
• Allow empty passwords for cameras
• Run every thread using RestartableThread so that it gets awaited during shutdown
• Fixes the move_on_shutdown: true config option. Previously Viseron did not wait for the callback to finish before exiting.
• A condition was missing when searchng for files for move_on_shutdown causing files to be moved multiple times
• Delete from FilesMeta table manually instead of using a trigger
• Properly throttle the function that checks if any files should be moved. This cause issues with attempting to move files multiple times
• Event clips are now generated in the servers timezone instead of UTC

Cleanup jobs

Multiple cleanup jobs now run regularly to make sure to keep the database and filesystem clutter free.
For instance if you delete files manually while Viseron is not started, the cleanup jobs will make sure that they are removed from the database.

They are intentionally throttled to run quite slow to not degrade performance of your host.

• OrphanedFilesCleanup (Mondays, 3 AM)

  • Removes files that are no longer associated with any recordings or events

• OrphanedDatabaseFilesCleanup (Wednesdays, 3 AM)

  • Cleans up database entries that point to non-existent files

Full Changelog: v3.0.0b11...v3.0.0b12

This release mainly contains new functionality to keep all the players on the Event/Timeline views in sync.
It can currently be a bit unclear if a stream is paused or not when it gets out of sync due to missing segments, that will be improved in the next beta.

Many performance improvements have also been made:

• Fetching available timespans is now done over websocket instead of through the API which reduces the amount of requests made significantly.
• If many events came close together it could cause stalls since each event would trigger a refetch from the API. These refetches are now debounced to avoid this.
• The entries in the event table is now virtualized (and the thumbnails only load when you stop scrolling).
  This significantly reduces lag and sluggishness of the table when having lots of events displayed.

And lastly, React has been upgrade to version 18, along with MUI v6 and React Query v5.
Togheter these upgrades should also equate to some performance improvements.

Details of all changes

• Sync all active players on the Events/Timeline page
• Upgrade to React 18
• Upgrade to MUI v6
• Upgrade to react-query v5
• Update timespans over using websockets
• Use system event listeners to refetch event queries
• Custom video controls
• Pick correct stream format config for substreams
• Massive performance increase for the Event table when having many events

Full Changelog: v3.0.0b10...v3.0.0b11

This release is focused mainly on a new layout for the Events page.
You can now select multiple cameras at once and they will be shown in a grid. Camera streams will automatically resize to give as much coverage as possible.
Selecting cameras is done using the floating action button in the bottom right corner.
The streams are not yet properly synchronized. I will work on that for a coming beta.
Here is a short demo of the grid:

There is also a new filter button located next to the Events/Timeline tabs that allows you to filter out only the relevant event types.

Details of all changes

• Adds filters to the Events and Timeline tabs so you can filter out only the events you want (Motion, object, ALPR etc)
• Upgrades HLS.js
• Fix calling loadSource twice when viewing 24/7 recordings, resulting in a browser console error
• Generate HLS segments directly from ffmpeg instead of writing mp4 files and manually fragmenting.
  This significantly improves the stream quality and removes some choppyness.
• Make Events page more compact by removing the camera selection grid. Selecting cameras is done using the floating action button in the bottom right corner
• Never delete a frame from memory if it is still the current frame.
  Should reduce some intermittent errors in the logs
• Use the ffmpeg hls_flags program_date_time option to get the exact creation time for segments. Previously milliseconds were discarded causing some timing issues
• Use settings under recorder for transcoding the generated segments
• Events page now allows selection of multiple cameras and shows them in a grid with a dynamic layout based on the screen size
• FFmpeg now deletes segments on its own in case of a Viseron crash
• RegEx performance improved to avoid hanging on large m3u8 playlists
• Improve speed of SQL queries
• Camera cards now has status text and indicators showing various states
• Frontend optimizations
• Fix missing sahred frames of motion and object detecors
• Enable safe mode if config fails to load (if a secret is missing for instance)
• Other minor bug fixes
