I've uncompressed the log/backtrace. The relevant part seems to be free'ing a non-existant pointer in libavformat following "Could not find codec parameters" in avformatdecoder::openfile

We shouldn't be attempting to close the file inside av_close_input_file() because we never opened it inside av_open_input_file() because we set fmt->flags |= AVFMT_NOFILE. I think we're going to need a sample file that causes this in order to diagnose the problem. Nothing obvious stands out to me. Closing for now until we get more debug info. Wish we had a "NeedsMoreInfo?" reason....
