From 1a0adaf37c30e89e44d1470ef604a930999a5826 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Fri, 27 Apr 2007 12:31:25 -0300 Subject: V4L/DVB (5345): ivtv driver for Conexant cx23416/cx23415 MPEG encoder/decoder It took three core maintainers, over four years of work, eight new i2c modules, eleven new V4L2 ioctls, three new DVB video ioctls, a Sliced VBI API, a new MPEG encoder API, an enhanced DVB video MPEG decoding API, major YUV/OSD contributions from Ian and John, web/wiki/svn/trac support from Axel Thimm, (hardware) support from Hauppauge, support and assistance from the v4l-dvb people and the many, many users of ivtv to finally make it possible to merge this driver into the kernel. Thank you all!
