DEV NOTES

DONE:

housekeeping and refactoring

• factored Alert class out of main controller and into main GUI
• factored Irc pump out of main controller and into chat controller
• added Alert::Initialize(), Alert::Push(), Alert::AreAnyPending()
• moved AvCaster::Alerts, AvCaster::IsAlertModal to Alert::Alerts, Alert::IsAlertModal
• moved AvCaster::DisplayAlert() to Alert::Display()
• moved AvCaster::OnModalDismissed() to Alert::OnModalDismissed()
• removed AvCaster::GetModalCb()
• renamed AvCaster::InitFail() to AvCaster::PumpThreads()
• added Trace::EnableTracing() and Trace::*Enabled to allow runtime toggle of logging
• removed AvCaster::GstVersionMsg(), AvCaster::PumpIrcClient()
• added AvCaster::VersionMsg()
• added IrcClient::VersionMsg(), IrcClient->pump()
• added AvCasterStore::shutdown()

CURRENT:

TODO:

Packaging:

Jucer:

• change listeners of old form SliderListener to new form Slider::Listener AvCaster:
• GetIsEnabled() functions and possibly IsEnabled vars are probably not needed - perhaps their semantic could be to set *_ACTIVE_ID storage false and disable the control buttons AvCasterStore:
• eliminate FIX_OUTPUT_RESOLUTION_TO_LARGEST_INPUT
• consider the ApplicationProperties class
• it may possible to use verify*/sanitize* to eliminate Seeds class IrcClient:
• bitlbee login fails if another client already logged in
• how to detect other mods in lctv chat
• implemenet chatlist kick button Gstreamer:
• eliminate NATIVE_CAMERA_RESOLUTION_ONLY
• eliminate AvCaster::GetVolatileStore(), Gstreamer::ReloadConfig(), AvCaster::GetIsPreviewActive() by passing Store->config into Config, Controls, Gstreamer
• implement text (partially implemented but disabled)
• implement interstitial (currently implemented as fauxsrc)
• replace testvideos with alpha img or fakesrc
• verify the runtime dependencies
• connect remaining config GUI controls
• sanity checks/validations
• test for device/screen existence
• detect camera resolutions and implement device storage (moving CAMERA_RES_ID out of main store)
• scale inputs to fill compositor output
• consider URL::isWellFormed() Gui:
• styling
• tooltips
• translations "audio" button does not turn green "preview" button gets enabled and turns green via stream select even if --no-preview "record" button does not change to "stream" via stream select misc: -Wunused-function -Wunused-variable MessageManagerLock mml (this); if (mml.lockWasGained())

NOTES:
