Vilius Grigaliūnas	ff6b08141a	acvodec/lipopenjpeg: Fix pixel value shift for 12-bit pixel formats This fixes pixel values not being properly shifted in libopenjpeg_copyto16 and libopenjpeg_copy_to_packed16 methods. Pixel formats like xyz12le need to be shifted by AVComponentDescriptor::shift to get the correct values.

Vittorio Giovara	e96c3b81ca	avutil: rename AV_PIX_FMT_Y400A to AV_PIX_FMT_YA8 The rationale is that you have a packed format in form <greyscale sample> <alpha sample> <greyscale sample> <alpha sample> and shortening greyscale to 'G' might make one thing about Greenscale instead. An alias pixel format and color space name are provided for compatibility.	10 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.
