First, check the GST_DEBUG log to see which pad exactly is flushing. I
am going to assume it's one of your avbdemuxer pads.

Are you adding the pads dynamically after starting up? If yes, you need
to do gst_pad_set_active() to activate them before pushing events or
data.

Hard to say more without seeing some code or debug logs.
