Detailed Description

Misc test sources.

testsrc is based on the test pattern generator demuxer by Nicolas George: http://lists.ffmpeg.org/pipermail/ffmpeg-devel/2007-October/037845.html

rgbtestsrc is ported from MPlayer libmpcodecs/vf_rgbtest.c by Michael Niedermayer.

allyuv, smptebars and smptehdbars are by Paul B Mahol.
