When there are multiple entities between the sensor and CFE device (e.g.
a serialiser and deserialiser or multiple mux devices), the media graph
enumeration would work incorrectly and report that the frontend entity
was not found. This is because the found flag was stored locally in a
boolean and got lost in the recursion.
Fix this by explicitly tracking and returning the frontend found flag
through the return value of enumerateVideoDevices(). This ensures the
flag does not get lost through nested recursion.
This flag can also be used to fail a camera registration if the frontend

This provides better integration with meson, such as the

This is also needed because the upstream CMakeLists.txt is
out of date, failing with a sufficiently new cmake version:
CMake Error at CMakeLists.txt:2 (cmake_minimum_required):
Compatibility with CMake < 3.5 has been removed from CMake.
The above is nonetheless addressed by https://github.com/yaml/libyaml/pull/314,
but the project seems a bit inactive at the moment.
The wrap file was added using `meson wrap install libyaml`,
and it can be updated using `meson wrap update libyaml`.
`default_library=static` is used to match the behaviour of the
previously used cmake build. `werror=false` needs to be set
because libyaml does not compile without warnings, and that

Whenever a downstream element queries latency, libcamerasrc will always reply,
even though it has not yet determined the latency.
However some downstream elements (e.g. glvideomixer/aggregator) will query the
latency before libcamerasrc sets the caps. When these elements get the latency,
they will start the caps negotiation. Since libcamerasrc has not yet determined
caps, invalid negotiation is performed and workflow is disrupted.
So, set latency to 'GST_CLOCK_TIME_NONE' during initialization, and reply to the
query after libcamerasrc confirms the latency. At this time, libcamerasrc has also
completed caps negotiation and downstream elements work fine.
In addition, every time the src pad task stops, we reset the latency to
GST_CLOCK_TIME_NONE to ensure that when next time task starts, the downstream
elements can generate out buffers after receiving the effective latency.
