Gst::Element.planying?


#1

Hi,

the docs for Gst::Element show the methodes
paused?
playing?
ready?

but they are not implemented in the current SVN. Only in
gstreamer/test/tc_element.rb are tests for them.

Were they never implemented or removed? I think, they are handy.

Cheers, detlef

They will not be implemeted.
I forgot the detail but the reason why they were removed is that they
are not safe.

GStreamer is a multi threaded library.
In the following code, “element” may not be “paused” in “# something”
even if
“element.paused?” is true:

if element.paused?
# something
end

Element’s state may be changed in other thread.
GStreamer provides a signal to handle state change. (Sorry. I forgot
the signal name)
You should use the signal to handle state change safely.

I’m sorry if the description is not correct.

I don’t have an environment to confirm the case…

P.S. gstreamer/tests/ directory is deprecated. We will remove the
directory
after we implement all methods in gstreamer/test/. We also need help
for the task.

Thanks,

kou
