I believe the TT S2-6400 DVB-S/DVB-S2 card has two frontends that can be used simultaneously.

but is has only one frontend per adapter, so it has no multi-frontend

Hi Lars, I have got the sc plugin working with your hybrid patch v2 and introduced the premium card and all is working well. Are you planning any more revisions to the patch? Or at least a 1.7.22 version?

Not really, because the driver changes introduced by Manu are on its way into linux-media. After that only one frontend will be left and new ioctls are there to switch between delivery systems. Rumours say Klaus is working on it for vdr 1.7.23... :-)

But if you like, you can send me your changes. I'm curious about them.

Lars.

Thanks, Mark.

Hi Lars, First reports on v2 of your multi-frontend patch with HVR 4000 card:

• can switch between both frontends successfully and very stable with

repetitive tests

• timer behaviour as expected
• switching response seems quicker than before
• Streamdev and xineliboutput plugins compile OK. Xlo tested OK, will

look at Sd later

• Have modified Rotor plugin to fit (maintaining personal version) and

all seems OK

• Working through sc plugin changes to fit.

If I can get the sc plugin working I'll move across a sd premium card into the mix and see how it behaves, watch this space ... While this is all good obviously things will no doubt change when Klaus releases 2.x with the new multi-frontend adapter handling. However, reading between the lines this may not be in the immediate future so an interim workaround for these cards is appreciated by me and I expect others ... Thanks and keep up the good work. Mark.

Hi,

Here's version 2 of my multi-frontend-patch. It's still "dirty", since it changes the constructor of cDvbDevice which will break compilation of some plugins. But I think it might be necessary to look at the relevant plugins since they might need to react on frontend changes. I haven't tested any of those plugins but will have a look at some that I'm using. Maybe there have to be some virtual functions like "BeforeFrontendSwitch" and "AfterFrontendSwitch" so the plugins are even able to know about it.

Assumption for this patch: All frontends within one adapter have to be used mutually exclusive. All cards I know behave in this way. If there are cards with multiple frontends which can be used simultaneously I'd like to hear about it.

Whenever the dvb-api-changes are upstream (the ENUM_DELSYS thingy) I think my patch can easily be converted to use that.

I'm still working on this patch, it's not finished yet... :-)

Have fun,

Lars.

Version 1.7.23 will contain multi frontend support with the new API.

Will 1.7.23 require a kernel with the new API or will it be backwards compatible? Otherwise, s2apiwrapper ftw! ;)
