Send custom graph event after audio stream change
MPC-HC has an option to show some details of the current audio stream in its statusbar. However, this info is not updated when the stream is changed through LAV Splitter. And of course I would like to avoid having to frequently check the graph for changes.
Could you send a custom graph event when audio stream is changed? https://learn.microsoft.com/en-us/windows/win32/directshow/cbasefilter-notifyevent madvr uses 0xfa17 as a custom eventcode, so I suggest using a value in a similar range.
Changing an audio stream by the user stops and restarts the graph, that seems like quite a noticeable event to watch for.
That only fires the generic EC_PAUSED event, which is quite common, e.g. fires after each frame step or pause.
I could use that. But would be less efficient.
