Comment (by w3sip):

 Have you ran it with -f mjpeg?

 As to the facts:
 - this camera produces an mpjpeg stream
 - this stream was previously detected as mjpeg, and that worked, albeit
 generating a ton of warnings (for the envelope multipart data)
 - for some reason, ffmpeg, even with the most recent changes, doesn't like
 this mpjpeg stream (though, as I've personally and hackeron have tested,
 it's just fine with the wget's output)
 - to resolve this I suggest either providing us with a packet capture
 (full tcpdump/wireshark output, containing both the request and the
 response), *or* making this camera available for us to test against
