FAQ: LAN Broadcasting with DVB Dream

[dwarves]

it doesn't work for me... i can't watch via wifi

Tested OK with DG834G or WG602 as transmitter and several WiFi receiver.

what i do wrong...

do you change any setting in your wifi router?

what version of vlc you have?

[FredB]

I haven't done any special modification on the 2 WiFi routers. There are both configured to use WPA encryption and filters MAC addresses.

Nota : only WiFi functions of the DG834G are in use, routing is done by a Zyxel Zywall 10W. So both DG834G and WG602 acts only as WiFi Access Point.

You should try to modify buffer size in DD netstream configuration (I've set it at 18 Kb).

I actually use the latest version of VLC : 0.86a

to all experts
i had configured dd and vlc a long ago without any problems, but used to turn it on rather occasionally. why? - i explain it later. i prefered altdvb with its server, because was able to control everything - altdvb "client" application was installed on my laptop. but it appears that altserver-altdvb "client" configuration is very "sensitive". everything is ok when main pc is only streaming. if any additional task on main pc is performed, you are not able to get video and audio. i'm not expert and cannot solve this problem. it drives me mad. had checked that configuration dd-vlc worked perfectly in the same time. dd-vlc seems to be far and away "resistant" than altdvb. i would like to use dd-vlc, but when i turn dd-vlc on, i've only got audio track of dvbdrem on main pc. main pc is always occupated by my son and you can imagine what is going on when i try to turn dvbdream on...
maybe it is stu*** question, but as i said, i'm not expert. how can i turn audio track of dvbdreamon off on main pc, giving my son possibility to use main pc without limitation during use of dd-vlc?
any help would be appreciated

Hi there!
some questions about dd lan streaming.

1. will be plan to add multicast udp streaming
( like udp://230.0.0.10:12345) instead of udp broadcasting?
udp unicast works well, as an udp broadcast, but multicast is more preffered than broadcast.

2. about channels names in vlc navigation -> programm tab

if i stream main window + some pip via lan,
there are no channels name, only SID numbers (20105 instead of "Traditional Country" on xtramusic (astra 19, 12052,H,27500))
I compare PMT/PAT tables from this transponder, using TSReader:

from dd stream:

so, is it possible add a real service name to dd stream ?

[Gldansky]

Just setted up network streaming!

Everything works fine, I can transfer a lot of streams at same time, but I've discovered a bug. Not all channels in VLC have sound! While they play on main computer, on client side you get no audio. This mostly applies to TPS package channels.

[CommGuru]

Hi all, I've read all I can find about my issue but can't find a solution. When I set DVBDream to stream, my client see's the stream fine but no channel numbers are populated under the Navigation option in VLC. It seems just random ones are listed there (not the channel what DVBDream is tuned to) but when I look under navigation in VLC and tune DVBDream to one of the channels that are listed, bingo i get a good stream output on VNC.

So I'm wondering what function is used to add the current channel to the VLC navigation selection.

I have exactly the same problem. The numbers listed under "Navigation"-> "Program" are fairly random and the numbers do not always have the channel (SID) that I am trying to stream to VLC. If I change to another channel on DD, the program numbers change on VLC, but still not to the channel I am trying to stream. Like CommGuru, I can set DD to a channel that VLC shows on the program list and it does stream that channel. How do I get the channel I am watching on the Host to show up on the VLC program list?

[FredB]

Sorry, can't reproduce this .

Numbers listed in VLC's navigation menu are SID from the streamed channels...

[soccerdad]

If you only have one channel open in DD, do you see more than one SID in VLC? With only 1 channel on in DD, I see anywhere between 4 and 6 channels in VLC, but they don't always have the channel I have open in DD.

[FredB]

No if there's only one channel displayed in DD, there's no entry in VLC's navigation menu.

how i can stream to internet ?

I just tried this streaming part through VLC. It works, but I have to select the PID in VLC Naviggation menu... the problem is that it does not always correspond to the channel that I am watching.

I think this has something to do with PIP button and I see a bunch of channels listed. I don't know where I manage these, or how to even delete them. Trying to find some info on this... if anyone knows I would appreciate a reply.

Also, is it possible to stream this to sopcast Server?

[TurboTronix]

I was wondering when running on a network, which of the pc's is actually doing all the processing? Like lets say I got a powerful PC and one slightly less powerful, which one should be the sender and which one should be the receiver?

Can HDTV feed be transmitted as well without any freezes?

I hope this helps others. Try VLC 8.4a. I could not always see the channel I was streaming, but others were listed with the latest release of VLC. Rolling back to 8.4a fixed it and now I almost always see what I am streaming.
