hi folks
I'm working on EM840x REALmagic DVD/MPEG-2 Audio/Video Decoder, There
is only official binary driver on Sigma designs website. Is there any open source driver or non-official driver ?

Please cc: to me as I'm not on the list

Sigma designs are known to not cooperate very well with open source projects. Actually, it's quite the contrary. Some time ago they released the XVID mpeg4 codec as their own, without source code.

I have heard of people trying to get documentation from them, but I don't think anyone ever succeeded.

Somebody put the datasheet and drivers on his web site.

Those guys have been under intense pressure from M$ protecting the desktop multimedia market. Each time their product managers announce some Linux support or product within the next quarter, it ends up being a year and only available for MS-whatever-the-hell-its-called-now.

My brother and I wrote a driver for em8400 supporting the Linux DVB API when we were at convergence (www.convergence.de), but they haven`t released it. There was a short discussion about it on the linux-dvb mailing list (see archives at www.linuxtv.org), but it looks like it is not clear who they have to ask and what they have to do to release it.
