Restreaming DVB-T multicast

[dbrb2]

Hi All,

I've been looking at DVBlast, a VLC based project designed to restream DVB streams multicast onto a network. This looks ideal for what I want - but I did have one question:

Ideally I would burn the subtitles into the stream at source (or not), so that they were on (or off) for all viewers, and the dumb clients didn't have to worry about turning them on/off locally. As far as I can see this is not possible, and would involve transcoding the stream, rather than just restreaming it (and therefore require much more processing power). Is this indeed the case?

Burning means changing the pictures and changing the pictures means decoding and re-encoding.

That makes sense. I've been trying to get together a sensible command line string to achieve this, and so far have:

cvlc
--dvb-adapter=0
--live-caching=300
dvb-t://frequency=xxxxx:bandwidth=8
:sout=
#transcode{vcodec=h264,vb=0,scale=0,acodec=none,scodec=dvbs,soverlay}
:duplicate{dst=rt{dst=232.54.1.1,port=5004,mux=ts,ttl=5},dstisplay}
:sout-keep

But this gives me:
main stream output error: stream chain failed for `transcodesoverlay:duplicatedstisplay'

I imagine it is something fairly basic - can someone suggest what my error is? Cheers!

Bad quoting.
