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.

Stefano Sabatini	68bed67d2e	pngdec: relax condition for setting monoblack pixel format Ignore color_type information for setting the monoblack pixel format, only rely on bit_depth. In particular: fix Test_1bpp_grayscale.png from issue #172. This may work fine for some broken encoder, and not for others.	14 years ago

Reinhard Tartler	7ffe76e540	Merge libavcore into libavutil Done to keep ABI compatible. Otherwise this is just silly	14 years ago
Reinhard Tartler	737eb5976f	Merge libavcore into libavutil It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.
