Description

I think it would be really awesome, if the Elgato/Geniatech EyeTV 4C (and maybe also EyeTV 4Sat)'s trancoded streams could be used as input-streams for the tvheadend.

The h264 streams provided by EyeTV 4C is better capable of meeting low bandwidth requirements.

Example: Lets say you have the EyeTV 4C on your network - and you have a laptop running tvheadend. Then it seems stupid to transfer the Transport-stream, when the device is capable of creating h264 streams directly.

Often you also just want to forward the h264 streams using the tvheadend - and tvheadend wouldn't in such cases need to trancode the stream to h264 again. It would really be awesome, because the server wouldn't require cpu for doing the transcoding.

I have Elgato, but still not found how to activate transcoding from device, even with their software. /even with access to device/

I have a dump from the Android Netstream App, where you can see, the transcode called.

Good luck implementing that. As it's HTTP-based SAT>IP with some vendor-specific additions you will need to write a completely new input source for that.

I not 100% shure but its not clear how session re-request is send from app to device
Client | STB
ASK RTSP stream >
PLAY rtsp://10.0.1.233:554/?&freq=554.000000&sr=6875.000000&msys=dvbc&mtype=qam64&inv=0&wait=0 RTSP/1.0

< Return
RTP-Info:url=rtsp://10.0.1.233/stream=6;

I dot't thing so
currently TVH wot OK with SAT>IP protocol with is also nonstandard
https://github.com/tvheadend/tvheadend/blob/c3204bc6ff87deed26a3bd8ef7a8224a50606dc3/src/input/mpegts/satip/satip.c#L582-L633

it use "Session ID" to get transcoded stream
so hack need to have "optional" Transcoding checkbox with Warning "will work with ONE FREE service total"

And you need to rewrite everything to add HTTP Support according to the pcap files, and you need a periodic poll of the signal strength aswell....

As i see RTSP session is not used anymore when transcoding used.
Transcoding use http session with same id with SAT>IP SETUP/PLAY request

Maybe we could contact and hear og they are willing to help with some full communication details.. It should indeed be in their interrest to male their awesome tuner work with tvheadend.. I'm pretty sure this functionality could boost their sale og 4C and 4SAT

Did you hear from Geniatech since then? It's indeed very interesting.
