Hi,
I wrote a patch to Steve Toth hvr3000 repository, so my FlyDVB Trio can use multiple frontend.
The bus of the two frontend is shared, isn't possible to get access to both frontend simultaneously, so I get an -EBUSY error by trying accessing frontend1 if frontend0 is in use.
VDR doesn't support yet the second frontend, and it try to get exclusive access on both frontend on start, so the second frontend is inusabile.
Vdr should probe for multiple frontend at start, and access frontend only on channel change.
Wouldn't it be better to hide this deficiency in the driver? Klaus
Actually it seems that on Hybrid card is and will be quite common that multiple frontend share a single bus.
Linuxtv API tell that a driver may offer frontendN nodes www.linuxtv.org/download/linux-dvb-api-1.0.0.pdf that vdr don't support
I think is impossibile, to solve by driver, since switching between frontend happened by opening the frontend/demux device.
VDR try access to frontend on start (actually it doesn't start multiple fe on same adapter, so I solved with symlink), and open all the frontend.
If open fails it refuse to use the frontend. If open with success, it start N thread as many as the number of adapter/frontend.
I don't understand what you mean for deficiency, if you mean the EBUSY, yes I could remove it, but it doesn't solve since with two tread open I should get a ping-pong between the two frontend so I can't get any image.
If you mean for deficiency the two frontend on the same adapter, is logically correct, and is a deficiency that vdr doesn't supporti t.
Since I like VDR, I'd like it support this.
Best regards
