Updated GstLevel methods for creating and populating message to use GValueArray (2.95 KB, patch)
2012-02-17 16:46 UTC, Peteris Krisjanis 		none Details | Review

Description Peteris Krisjanis 2012-02-17 16:45:27 UTC 
I can't access rms/peak/decay keys from bus GstLevel element message, because they are exposed using GstValueList, which isn't supported by Gstreamer GI. When I try to access them Python returns TypeInfo error about that it can't access GstValueList because it doesn't know that.

Solutions would either expose GstValueList to GI, or return variables in another type of array/list, for example, GValueArray.

 - combine  g_value_take_boxed() and g_value_array_new()
