thanks. It was late and whne i previously opened the file i didn't realise there was a folder inside...
anyway, here is a "hack" for the audiosink to give you sound on those streams.
BUT, i have no idea about side effects at this stage. I've changed a particular catch all routine when there is no codec data to construct the aac header from.
so please test this with other streams to see if you are loosing audio where you had audio so far.
Also test this with movie files with aac audio.
meanwhile, i'll have a think about the not smooth video..
enjoy,
