gst_element_post_message: bus is NULL

[mick_coracin]

Hi,

I'm using a Playbin2 based pipeline with a custom Bin for source.

I would like to send a GST_MESSAGE_ELEMENT message from this bin to the application so that this bin can be reconfigured based on some user defined options.

I'm trying to use gst_element_post_message() function from my Bin, but I get a "No Bus" error. The bus of the element is NULL.

I understood that the bus should be inherited from the parent bin or pipeline, but it seems not to be the case here.

Do you have any idea why the bus is not set in this case? Where should it be initialized, and can I force it to be set?

Thanks and regards,
Michael

Are you sure your bin is actually in use (aka plugged into the
pipeline)? It would be good to post a minimal standalone example that
shows the problem.
