We cannot use track-processor-js for Firefox because it uses various
approaches not compatible with Firefox. Firefox cannot run inference
on GPU, so we must use CPU, we could also not use MediaStreamTrackProcessor nor
MediaStreamTrackGenerator. So I had to make a new implementation from
the ground up, using canvas filters and CPU inferences.
Improved script portability by switching to `/usr/bin/env bash`, ensuring
better support across environments where `bash` may not be the default shell.
Avoid disabling SSL verification in development environment,
simply mount in the right folder, an extra volume, that declares
the certificate authority necessary to validate nip.io domains.
Updated deployments metadata to include configurable annotations using
`.Values.xxx.dpAnnotations`. This change supports the new approach of
storing secrets in an external Vault, allowing annotations to be added in
staging/prod to trigger refreshes when external secrets change.
Will be configured accordingly in La Suite deploiement repository.
Refactored ClusterSecretStore and ExternalSecret deployment to support
VaultWarden custom fields beyond login/password, including multi-line
values via file input. Also made the secret template name configurable
for added flexibility.
ClusterSecretStore are supposed to be cluster-wide objects, it's useless
to precise any namespace.
Previous merge of helm chart refactoring was incomplete. Currently,
linting only occurs during chart publication rather than on each PR.
This temporary solution will be improved in a future update.
Existing make command wasn't working on Mac. Fixed it, plus
refactored it in a proper script, so we can share it among
projects, as for the build kind cluster one.
External secrets are created in a dedicated namespace, to avoid
duplicating them if we spawn several LaSuite applications on the
same local stack.
Fix the following issue :
```
The workflow is not valid. .github/workflows/release-helmchart.yml
(Line: 25, Col: 12): Job 'release' depends on unknown job
'helmfile-lint'.
```
Use the common create_cluster.sh in order to improve cooperation
between teams.
Also, mount extra volume, to avoid setting ssl_verify to false,
while using request module in Python.
We have a dedicated deployment repository, also containing
the Helm chart. To avoid duplicating and maintaining twice
a chart, we decided to publish our Helm chart.
At first we tried the official chart releaser action, however,
this ended in creating a new release on Github for each chart
update, which wasn't acceptable.
Offer a standalone dev environment or a dinum specific dev
environment with ProConnect authentication.
Needed to refactor the way secrets are managed in the project,
and also re-organize the Helm chart to make it totally standalone.
Particulary useful for external wanting to run the project.
Work done by @rouja.
Submitting new users to the marketing service is currently handled
during signup and is performed only once.
This is a pragmatic first implementation, yet imperfect.
In the future, this should be improved by delegating the call to a Celery
worker or an async task.
Introduced a MarketingService protocol for typed marketing operations,
allowing easy integration of alternative services.
Implemented a Brevo wrapper following the protocol to decouple
the codebase from the sdk. These implementations are simple and pragmatic.
Feel free to refactor them.
Found this solution googling on Stack Overflow.
Without a default ordering on a model, Django raises a warning, that
pagination may yield inconsistent results.
The new endpoint requires title and content, breaking
the original implementation. This hotfix ensures staging works
immediately while I plan an LLM-based solution
for title generation.
It led to an error, with two occurrences of the form's URL being
desynchronized. Fix this minor issue, and refactor the constant
in a constant file to be shared across the app.
Enabled recording feature in production. MinIO needs to trigger a webhook
when a new recording is saved. Secret will be updated in the upcoming commits.
Updated the webhook URL to the definitive version in docs.
Jacques also updated the webhook secret for authentication
against Impress API. Not tested locally.
We want to have a specific responsive menu on mobile browsers.
It also implied to refactor a bit the way the settings modals is opened
because it could be opened from this responsive menu, so in order to achive
that a specific context has been created in order to allow its opening
from any sub component of the control bar.
We want to be able to customize the variant which those toggle uses as
well as being able to trigger an event when the toggle is pressed. This
is going to be useful to close the responsive menu after each clic as
react-aria prevent click event propgation.
According to the documentation:
Dynacast dynamically pauses video layers that are
not being consumed by any subscribers, significantly
reducing publishing CPU and bandwidth usage.
Dynacast will be enabled if SVC codecs (VP9/AV1) are used.
Multi-codec simulcast requires dynacast
My goal is to reduce CPU and bandwidth usage for clients.
Dynacast is enabled both in OpenTalk and LiveKit demo app!
Adaptive stream is a key optimization in large room.
Enabled adaptive stream to automatically manage
the quality of subscribed video tracks, optimizing
for bandwidth and CPU usage.
When video elements are visible, it adjusts
the resolution based on the size of the largest visible
element. If no video elements are visible, it
temporarily pauses the track until they are visible again.
Additionally, introduced support for custom pixel density,
which defaults to `2` for high-density screens
(devicePixelRatio ≥ 3) or `1` for standard screens.
Setting it to `screen` allows the pixel density to match
the actual screen's devicePixelRatio, optimizing video
clarity on ultra-high-definition displays.
This ensures a balance between streaming quality
and resource consumption.
This might also significantly increase the bandwidth
consumed by people streaming on high definition screens.
It needs to be battle tested.
OpenTalk uses a adaptiveStream equals true, while LiveKit
demo app uses 'screen' value. I followed OpenTalk choice,
I was scared 'screen' value creates performance issues
for user with high resolution screen in poor network conditions.
As a mandatory codec in WebRTC specifications, VP8 serves as
the baseline for compatibility, making it the default choice
in LiveKit client configuration.
There is room for optimization.
Newer codecs like VP9 offer significant efficiency gains
compared to VP8, with a 23-33% improvement in compression
efficiency. This translates to better video quality at
the same bitrate or reduced bandwidth usage for the same quality.
VP9 is supported in Safari starting from version 15.0+,
and Firefox offers partial support. However, Firefox lacks
support for VP9's Scalable Video Coding (SVC).
With SVC, participants can send a single VP9 stream
with multiple spatial or temporal layers. This allows receivers
to dynamically adjust video quality by using lower layers when
resolution or bandwidth needs to be reduced, improving
adaptability in heterogeneous network conditions.
Simulcast, by contrast, sends multiple separate streams
at different resolutions. While widely supported in VP8 and VP9,
it consumes more bandwidth compared to SVC.
The configuration added here is based on the LiveKit demo app,
which defaults to VP9 when supported. OpenTalk’s configuration
also recommends VP9.
If a browser does not support VP9, LiveKit falls back to VP8 or
other codecs as needed. Notably, LiveKit disables VP9 encoding for
Firefox due to longstanding issues, but it can still decode VP9
streams and encode VP8 for outgoing streams. This ensures
compatibility with other participants, even in mixed environments
where some browsers use VP9 and others fallback to VP8.
In theory, participants do not all need to switch to a single codec,
as both LiveKit and browsers intelligently handle codec negotiation
on a per-participant basis. This dynamic adaptation ensures seamless
communication without manual intervention.
A similar challenge with codec compatibility was raised
in Jitsi two years ago, check issue #10657.
Before any release, this needs to be battle tested
with Firefox 115 browsers.
