Poste bloß nicht zu viele Infos ...
super, und ich habe meine xcard erst kürzlich verkauft...
Do u speak Russian?
Without a licence, an author, some documentation it's not really usable/useful...
Who wrote the driver? ....
It is reverse ingeneered SDK for chipsets em840x,em847x and 85xx from Sigma Designs , adapted for kernel 2.6.x series
I dont think that It can be published under GPL.
- added support of 64-bit architecture
- added support of newest kernel
- implemented new locking scheme; independent stream playback is possible
- video and audio playback is OK (see utils playaudio.c and playvideo.c)
PS it is expected the next release to be under GPL
What would be the advantage of using this driver rather than the sigma one?
I dont know sigma driver very well so ll make some speculations
1. The current driver is based on Sigma SDK. The Sigmas one is based on the same SDK but much more older version. So Im expecting that the current driver has more functionality.
2. The current driver is using hotplug to load microcode into chipset. You can extract microcode from windows driver and use it very well. The Sigmas driver is using old version of microcode, so Im not sure that it can play divx3 or maybe something else.
3. The structure of this driver is modular, so It is possible implement drivers for all PCI-board from Sigma with single interface. I have enough reverse-engeneered material to create driver for any Sigmas board (like NetStream, Ventura2000 etc) but I dont have that hardware and I cant test board-specific code. This is the only reason why the drivers for other cards are not made.
If the license is finally GPLed and you need some help in testing and adapting to different boards/chips, let me know ...
Ok, thats great
As soon as I remove some non-clean code from driver, I will start project at sourceforge-like hosting with GPL license. I will inform you
Can we ask for support in here ?
I am compiling this but with lots of warnings for:
implicit declaration of function `mdelay'
implicit declaration of function `udelay'
See the attached log.
Currently the em840x driver is disabled in svn, and it doesn't compile when being activated.
AFAIK there are much more em840x(Activy) users around here than em847x users, so it would be very nice to have this one working ...
P.S. Is your email address correct Master Yoda ? I didn't get an answer to my question some weeks ago
Support of em8400-based cards is under development. But I need help from owners of that cards. There is new module sigma-test.ko added in opensigma project. it conserns users of all Sigmas-boards (based on em8400 and em8470 chipset)
Please, read README about usage of that module
Hi, I tried new driver
It works fine, on x32 bits system.
Need demux mpeg2 file, and test with mpeg2 video stream:
cat file.mpv > /dev/sigma/video0
I will try port mplayer from realmagic driver to open-sigma, but I do not know if I can...
My knowledge of C++ not fine...
Helau, what you think about?
The mplayer part of em84xx is based on the fmp library, and does not communicate directly with the driver.
The perfect solution would be to write a new library for the open source driver, but I do not have the time to do something like that.
Also the current solution with the old fmp library and realmagic84xx driver is working for me good enough ...
I combile and modprobe realmagic
but show error : Unknown symbol remap_pfn_range .
the kernel is 2.6.9-22 Red Hat Enterprise Linux as release 4
test in Debian 2.6.25 ,drivers ok ,but no picture on screen,
lsmod can see xcard
