[Ffmpeg-devel] [PATCH] RGB555 without alpha and more converters

[Alex Beregszaszi]

Hi,

I changed the to/from rgba32 converter glue code to work with non-alpha
formats too. Thus now we have optimized RGBA32->BGR24,RGB565,RGB555;
BGR24->RGBA32 and RGB565->RGBA32 converters with the old code (without
swscaler).

Then I removed the alpha bit setting in RGB555. We might add RGBA555,
with the alpha setting code, but Michael neglected addict obscure
formats. I dont need this one, however its one feature more :)

Also I was unsure about the versionbumping of the libraries, the
imgconverter is placed in libavcodec, and now the RGB555 MSB is not set,
thus a version bumb is needed, i think. On the other side, the PIX_FMT
is defined in libavutil.

According to Michael, swscaler doesnt follows the "set-msb-of-rgb555",
thus with this patch, both codes should output the same formats.
