Tvheadend

Hey!

With very small changes I made the Sat>Ip compliant Geniatech Netstream 4C work with tvheadend. Please just take this as proof of concept!

https://github.com/mpietruschka/tvheadend/commit/bcce95ab771a41dd3cb5457ea26fe479427515f8

As I mentioned, the Sat>Ip specification recommends letting the Sat>Ip device select the frontend. In consequence, the Netstream 4c does not support the frontend/tuner selection and reports errorno 505 in case tvh tries to pass the frontend parameter.

I'd appreciate a checkbox in the tvh-adapter configuration, which could be named like "Disable fe (frontend) selection" or "FE supported". This should disable the "fe="-parameter in rtsp protocol.

The „fe=“-parameter is used to adress the frontend/tuner. Since tvh won't adress more then the 4 possible tuners, I don't think it's going to be a problem to remove the parameter for such cases. Except you'll use up all 4 tuners by another device. But even then tvh just won't be able to use the occupied tuners and reports a simple message.

Next missing thing is the "specinv=0" parameter for dvb-c devices. This should be passed to all dvb-c devices. Without this, the Netstream 4C does not accept the connection. In doubt this could be implemented as an checkable option, too.

Please see more details in https://tvheadend.org/issues/5101#note-39

I implemented the options in this pullrequests. The options are set automatically for netstream 4c devices and frontends.

https://github.com/tvheadend/tvheadend/pull/1137

So with #5231 50% are done :)

Both changes are pushed, what is missing?

Your right, nothing. You can customize both parameter to your needs now. Thanks again!
