Without doing this, FFmpeg will try to probe the streams to detect them instead. When it does this, sometimes it tries to read beyond the data that's available - and then gets confused by EOFs. Parsing this way allows us to control the situation. An example is Valkyrie Profile, corruption in the first frames of the second video during the intro. Thi doesn't fix it yet, but now it's just a matter of buffering.
