[FFmpeg-devel] [PATCH v2] avutil/pixfmt: fix AV_PIX_FMT_RGB8 description

[Jeffrey Knockel <jeff@jeffreyknockel.com>]

Previously AV_PIX_FMT_RGB8 was documented as "RGB 3:3:2,
(msb)2R 3G 3B(lsb)".  While the RGB 3:3:2 part is correct, the latter
part should be: (msb)3R 3G 2B(lsb).  This commit also updates the
format's pixdesc description to be (msb)3R 3G 2B(lsb).
