DVB-H

Would it be possible to use VLC to place DVB-H streams via the DVB-T device? (theoretically it should)
I can scan the DVB-H for the channels.conf using 'scan' as usual, and the codec is h.264 but implemented as bursts of data.
Hopefully this can be done sometime in the future :-)

according to that (sorry, Finnish only) it should be possible if your DVB-H provider doesn't use IPv6.

That's for that. The Finnish doesn't help me much, but I guess I can try and play around with the commands that I see.
Making the channels.conf was much the same as for dvb-t so that part wasn't a problem
I only notived the term 'vlc' written once on that page, so I'm assuming this is a generic back end, just using vlc to play it.
You've managed to actually watch dvb-h on your computer? I'm impressed :-)

I just ran that page through the google translator. It gave me an idea of some of the words, but really was only good for a laugh :lol:

If anyone is interested, I found this... in English :-)

I keep getting stuck on the dvbnet bit though

Not mine page, and I don't have tuner to test it. But the page uses
mp4player 4.sdp
for playback because according to that page neither mplayer nor VLC support IPv6 based RTP and in Finland they use IPv6.

I thought by the following statement it made, vlc could do it.
After that you can just open the video using vlc (->www.videolan.org) that has SDP support (see ):

vlc orf1.sdp
I still can't get past the dvbnet bit, because even though it sets up the network device, I can't bring the interface up.

Code: Select all

root@slax:~# ifconfig dvb0_0 up SIOCSIFFLAGS: Invalid argument
I'll try to figure out which IP version they use here in the meantime

By doing a dvbsnoop of the IP/MAC Notification Table (INT) [EN 301 192] I get this, which shows an IPv4 address

Code: Select all
