You can use "-flags2 +showall" to decode the file (and -copyinkf to copy
the video stream to allow testing other players).

I am not convinced that the stream is sane, feel free to do more
tests and report back. (I believe I remember other bugs in Makito

Please find out what "top-posting" means and remember to avoid it here.
