Answer 1

I have an dvb-t udp .ts stream generated with mumudvb and I can extract the EPG guide info in XMLTV format with epgrab - https://github.com/hiroshiyui/epgrab

git clone https://github.com/hiroshiyui/epgrab.git
cd epgrab/
cmake .
make
# Point epgrab to your dvb adapter
./epgrab -i /dev/dvb/adapter0/demux0 > out.xml

Hope this helps!

yes it does, i actually have mumudvb streaming, while ffmpeg extracts subtitles and epgraber gets the guide. all these three programs run from only one tv tuner – Equalizer

do you know how we extract epg from devlast stream? – Cuesta

don't know about a stream. If it's a Transport Stream I'm guessing it will have the EPG guide attached to it. I can see this EPG guide from VLC for example from a TS, but not sure how to extract it. My answer was for extracting it from a DVB card – Equalizer

Answer 2

I wrote a utility called dvbtee that can be used as a c++ library, a cross-platform command line utility, or a node.js module.

The command line utility will parse your streams and output the EPG, depending on the arguments you specify, it can generate plain text or a JSON block of data.

dvbtee: a digital television streamer / parser / service information aggregator supporting various interfaces including telnet CLI & http control

The node.js module will emit events containing the PSIP table data (along with EPG info)
