Tvheadend

It would depend on size of the stream, i would imagine (and this is only a guess) you would need to transcode.

I same as i got at home, it is only enough for radio streaming.
buy a second pi

I would suppose that probably i would need a transcode since the size of the streaming is major than the bandwidth.
Unfortunately I don't know if it is possible and how can I do it.
I could buy a second pi but it would not fix the issue since at second home i don't have a DTT signal.

Well, you could buy an aerial and a DVB-T tuner for the second house... I suppose you've thought of that, though.

There's a transcoding option in tvheadend. Search this forum and you'll find how to enable it; it used to be a separate branch but I believe it's part of master now. IIRC, you have to compile with a particular flag and then access the streams through a URL. I've never used it myself, though.

If i could use a DVB-T tuner in the second house, i wouldn't looking for a solution

I'm trying to find the transcoding option, but I cannot find it. Probably I have to compile it directly on my Pi.

You can transcode with VLC or ffmpeg, and you can get en acceptable picture on 1 Mbit/s, but Trancsoding requires alot of CPU power which you propably don't have on a Pi.

The following VLC command will keep the stream just below 1 Mbit/s

cvlc --audio-track=x http://user:pass@tvheadend_ip:9981/playlist/channelid/1 --sout '#transcode{vcodec=h264,venc=x264{aud,subme=5,ref=3,me=hex,bframes=16,b-adapt=1, bpyramid=none},threads=1,scale=1.0,width=480,vb=600,deinterlace=true,acodec=aac,ab=96,channels=2,samplerate=44100}:standard{access=http,mux=ts,dst=0.0.0.0:8081}'

You can then connect a player to the stream with http://ip_of_transcoder_server:8081

If you need authentication to the transcoded stream, just change the following {access=http{user=username,pwd=password},mux=ts,dst=0.0.0.0:8081}

I realise that for this to work in practice, you need to start the transcode automaticly, just before connecting to the channel, so you will need to write some script for that (Unless that is what is build into that special version, of thvheadend, which i can't find either).

Hope it helps..
