Hi PLi Team,

Previously i use Gemini image, but i think i will switch to PLi images because i think this community is more open.

I want specific feature for my dreambox:
1. network bridge support
2. easy to operate (have menu to add more addon+plugin, like Gemini or PLi does)
3. ability to use cam/emu for watch pay tv (like Gemini or PLi)

I think i have two option:
1. Building from scratch (using cvs source from tuxbox) + add cam/emu + add menu + add custom script, etc
2. Ask PLi team to enable network bridge feature (because from all my requirement, only network bridge is not support yet)

What i already done so far:
I already success enable network bridge in kerneland add bridge-utils package using cvs source from tuxbox.
But i still can't figure out how to add CAM (emu) on it.

I think it is kind a long journey for me to accomplish first option. I hope i can use PLi image as base for my custom image. Is it possible ?
Or at least, can PLi team guide me how i can meet my requirement?

ps.
I have DM500S

Thanks in advance

your box has only 1 network adapter, what do you intend to bridge between? Also, expect huge cpu load.

Hi pieterg,

I want to bridge dvb_0 (dvbnet) to eth0, using for receiving multicast ip via satellite. Yes, maybe the cpu load is huge, but this is my school project to make dreambox as multicast data receiver over satellite.

You're asking pieterg to do your homework for you???

Be aware the 500 has (partially) closed source dvb drivers. Are you sure you can get dvbnet working in the first place?

I know we are talking about a DM500 but does the dreamdata plugin on the OE boxes not do a bit of this now with the IPRadio option ? Can this be modded for the 500?

looks like it uses dvb0_0 somehow, so indeed perhaps dvbnet works.

[jonc]

I might add although it is there, I have never been able to get it to work, not that I have really tried.

No. The original task is only for utilize dreambox as multicast data bridge from satellite. I already finish that work using cvs source from tuxbox (see on my first post).
I ask PLi dev team just for another fun, integrating what i already test to PLi images, maybe someone need this too.

Just like i said in the first post, i already try dvbnet in dm500 and it is running fine.

multicast serv ---> satelitte --> dreambox ---> pc

from mcast serv i sent files using udp-sender or video using vlc, dreambox is bridging dvb0_0 and eth0 (only need activate bridge support in kernel and bridge-utils package), in pc i usin udp-receiver for receiving files or vlc for watching video.

Which kernel config options do you need, and how much kernel image size do they add?

only 1 option change is needed:
CONFIG_BRIDGE=y

This is only activating bridge feature on kernel. Before we can use it, we also need user space application, bridge-utils package, but i think this package should be fall into addon (not core module)

Interesting, i should dig OE box to find it, maybe we can modded this to tuxbox.

CONFIG_BRIDGE=y

any idea how much binary size that adds?
If it's not too much, we might just add it to our standard kernelconf.

Yes, and your tuxbox built binary should work as well.

without bridge support:
-rw-rw-r-- 1 dheche dheche 1032192 2008-11-09 20:48 boot-cramfs.img

with bridge support:
-rw-rw-r-- 1 dheche dheche 1044480 2008-11-09 20:52 boot-cramfs.img

So the diff is about 12288 byte
