-----------------------------------
sorry I meant clock_safe=false in the above.
> Failures / sleeps in v4l plugin
> -------------------------------
>
> Key: LS-439
> URL: http://dev.sourcefabric.org/browse/LS-439
> Project: Liquidsoap
> Issue Type: Sub-task
> Components: Liquidsoap
> Reporter: Samuel Mimram
> Assignee: Romain Beauxis
> Priority: Blocker
>
> We should make input.v4l faillible (it can fail when the webcam is not
> available or unplugged).
> Moreover, we should maybe also address this comment by David :
> "When they are turned off (#sleep) operators should free resources that they
> have allocated. Now that this operator allocates a thread, it should make
> sure the thread exits when the operator exits - it's also important in order
> to avoid having two polling threads if the operator is re-initialized. This
> can be done synchronously or not. We have similar problems with several other
> operators, and quite a bit of duplicated and clumsy code, which we should
> factorize and cleanup at some point."
> I am not sure that it really applies here though: the thread is created when
> the object for the operator is created (not when the operator is
> initialized). The polling thread is blocked on a condition which is signaled
> in get_frame: when the operator is sleeping, the thread simply gets blocked
> on the condition so it's not such a big problem...
