Ronald S. Bultje	d2205d6543	png: check bit depth for PAL8/Y400A pixel formats. Wrong bit depth can lead to invalid rowsize values, which crashes the decoder further down. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Reimar Döffinger	371e165443	Try to set AVFrame.reference to correct values. I am not sure these new values are correct, not am I sure the semantics are a good idea since we do not seem to make any use of them but they caused a lot of confusion, but this seems to make things closer to matching the documentation.
