For what I can see from the logs, maybe input() is called before configure(). Could you add a log in Input() @[1].

Hi Bruce,
you had mentioned that there was a memory issue for |SniffMP3|, now I can reproduce it on my pc.
Can you provide the bug number?

Thanks for information, but unfortunately my case is not the FileMediaResource case and also the MP3Sniffer doesn't reach the end of stream.

Now I had narrow down the testcase to one file seek.webm, and the crash point always in MP3Sniffer.
