Romain Beauxis reassigned LS-478:
---------------------------------
Assignee: Romain Beauxis
> Cannot use video.add_text since SDL init changes
> ------------------------------------------------
>
> Key: LS-478
> URL: http://dev.sourcefabric.org/browse/LS-478
> Project: Liquidsoap
> Issue Type: Bug
> Components: Liquidsoap
> Environment: current dev version
> Reporter: David Baelde
> Assignee: Romain Beauxis
> Priority: Blocker
>
> $ ./src/liquidsoap 'output.dummy(video.add_text("foo",blank()))'
> Invalid value at line 1, char 28-42: Library not initialized.
> The problem is that SDL is only initialized when streaming starts, just
> before sources are woken up, but the text operator initializes its font upon
> creation and not upon #wake_up. This in itself is (slightly) incorrect since
> resources should only be allocated within #wake_up and #sleep, but it is
> useful to check that the font exists.
> The simplest solution is that all SDL operators call Sdl_utils.init which
> inits with all options if not already done. The current architecture tries to
> do better by not initializing components that don't need to. This is nice but
> I don't see why it's necessary.
