Hi Tyson, all recent bugs for parseonly=true are caused by the same reason by "wrongly calling API". We are fixing it. Please wait for a moment for this kind of tests.
btw: as the flag bParseOnly is assigned as 0 in gmpopenh264, so it will not affect FF code.

Ok I'll hold off before I log the rest.

I figured the bParseOnly bugs didn't affect the ff plugin but I thought I should log them :)
