The purpose of the 0.5 series is to move the supporting drivers to the video4linux repository (and from there into the 2.6 kernel). No other features are planned. Bug fixes should go to both the 0.4 branch and svn trunk. Please note that this 0.5 series is unstable and very much work in progress. Do not use for a stable production environment. Developers that want to work on the 0.5 series should subscribe to the video4linux mailinglist since part of the work will happen there. The video4linux project is hosted on www.linuxtv.org. To build the 0.5.x driver you first need to check out the latest video4linux repository. To do that just run 'make v4l-checkout' in the ivtv top-level directory. To get the latest v4l CVS changes run 'make v4l-update'. To build the v4l tree run 'make v4l' and to install it 'make v4l-install'. When you run 'make v4l-checkout' you will be asked for a password. Just press enter here. The next step is to build ivtv as usual. By now all supporting drivers have been moved to v4l. These drivers will be maintained there in the future. IMPORTANT: the firmware names have been changed to more standardized names: ivtv-fw-enc.bin -> v4l-cx2341x-enc.fw ivtv-fw-dec.bin -> v4l-cx2341x-dec.fw HcwMakoA.ROM -> v4l-cx25840.fw ivtv_init_mpeg.bin -> v4l-cx2341x-init-mpeg.bin Hans Verkuil
