Can TV Client receive a stream from VLC? (1 Viewer)

[Stinky]

Does any transcoding have to be done to a RTSP stream from VLC to make it readable by the MP TV Client?

I have written a replacement TV server for my own use which uses VLC to redirect a UDP broadcast to the mediaportal client. Everything works fine, right up until the stream is received by the client.

I start VLC like this:
C:\Program Files\VideoLAN\VLC\vlc.exe --ttl 12 -vvv --color -I telnet --rtsp-host MPServer:554

I then use the telnet interface (programmatically) to send the following:

new Stream1 vod enabled
setup Stream1 input "C:\MyVideos\liveTVrecording.mpg"
-OR- (I've tried both)
setup Stream1 input "udp://@239.255.0.1:9400"

Then I have my "fake" server reply to the MP client with the following stream name: rtsp://MPServer/Stream1

I just can't seem to get it to build a graph. I get something like this in the client's mediaportal.log

2007-01-22 21:03:42.149625 [Info.][MPMain]: RTSPPlayer: load:rtsp://Mediaportal/Stream1

I've tried using different codecs in the client's MyVideos setup (MPV/MPA, PureVideo, etc)

It works just fine if I use a VLC client to connect to rtsp://192.168.1.134:554/Stream1 and it works if I use the MP server to stream video from my Hauppage WinTV-USB2. The messages in the VLC window say it's using MPV/MPA as well.

I know this is outside the MP client/server umbrella, but any suggestions would be appreciated. I think I'm really close to getting this to work.

Still have the problem but I discovered you have to force VLC to use TS as a mux:

new Stream1 vod enabled
setup Stream1 input "udp://@239.255.0.1:9400"
setup Stream1 mux mp2t

I still get the same erros in the MP log and nothing ever shows up in MyTV on the client. Now my server CPU goes to max, too. Should the load be that high? It's not a monster machine, 2.4 GHz, 1GB RAM..

In case anyone else tries this in the future, the solution was

new Stream1 vod mux mp2t enabled
setup Stream1 input "udp://@239.255.0.1:9400"

2.4GHz Celeron processor was fine as long as you wait for VLC to ctreate the stream before giving Mediaportal the streaming URL.

I can now watch IPTV within the Mediaportal interface working with the associated EPG. I've tested with three different streams running at the same time to three different clients and it's holding up nicely. Downside is that zap time has doubled since VLC has to "tune" in the stream, and then Mediaportal has the tune it in again.

This may actually be exactly what im looking for...
Let me get this straight, you are rederecting a udp stream to "MY TV" in MP using VLC?
Didnt understand all that mutch how you got MP to show the stream in "MY TV", but if i understood right, you wrote a replacement TV server which generally speaking is VLC?

I would love to test this out, been looking all over the net for a solution like this!

This might be where I end my search

hey guys,
could you give me a hint on the why? I just don't get the point.... I thought the TVE3 was doing exactly what you needed (besides VLC) but why do you need vlc, then?
cheers

TV Engine 0.3 cant handel the udp:// streams.
I get my IPTV through streams like this, and i can watch these channels using VLC, but untill now, i havnt been able to watch them in any of the Media Center solotions thats out there..

TVE3 is running on any Windows system. If you have a "full server" (not a disguised Pc), dedicated to streaming/recording TV, it may be intalled with a Linux distrib.
I personnally use a Debian server with one DVB-T and one DVB-S cards and use VLC on it as a TV server/DVR.
The main client is off course MP

Anybody interrested in developping a plugin for remote control of VLC server (stream, VCR, ...) ? If any, count on me (I'm a java developper but can adapt any language ) !

I was actually thinking of trying to learn C++ to make a TVE3 VLC plugin with the options of recordings, timeshifting, program guide and so on, controlled by the MP client..
I would be more than thankfull to get some help with this, when my programming skills is rather non existing, but then again, im willing to learn

Dont know is that was what you where thinking, but this would atleast complete my wishes.

not sure about this !!

Let's summarize a little what I was thinking about.
The main purpose of this MP plugin will be to control a VLC server within MP.
It includes planned (with or without EPG) and life recording on the server (recording and timeshifting an IP tv on the MP client is not the job here), adding/removing multicast streamings from files, IP tv streams and DVB cards (and maybe DVD), adding/removing files from playlist and asking for VOD (unicast stream).
All these "commands" can be send to VLC by the telnet interface and the VideoLAN Manager (VLM) functionalities.
Holy Bible for VLC streaming is there : http://www.videolan.org/doc/streaming-howto/en/index.html.

I don't know the new TVE3 and I'm not interrested in the server aspect (since my server is in Debian) but the client aspect can maybe (not sure) be combined with the VLC plugin to "use" the ip-streams cast by the VLC server. Anyway, ipTV plugin already exists (https://forum.team-mediaportal.com/my_ip_tv_plugin-t13558.html?t=13558) and is enough here to play our VLC streams.

Last question : what is this Videolan plugin about http://mp-plugins.svn.sourceforge.net/viewvc/mp-plugins/trunk/plugins/VideoLAN/ ? I could not find anything about it in these forums.

But like Stinky wrote this "is outside the MP client/server umbrella".

Hi guys, sorry for the late replay - I haven't checked the forum in a while.

I just replied to framerate via PM, but here's the jist of it:

My server listens for MP clients to request a channel (among other things). Once a channel is requested, I use the telnet interface to VLC to create a redirected stream (udp->rtsp) and then pass the new stream name to the client. I have two NICs in the server with routing tables set up - one to my LAN, one to the IPTV network. I also created my own DB table to hold the mapping between a channel ID (as used in the rest of MP) to a MRL used by my cable provider.

Setup is cumberome. I run the MP server setup only to use the DB structures (parts of the client talk directly to the remote DB and not to the server) and then disable the MP server in favor of my homebrew one. The routing tables were easy to set up, the DB table data was a pain to capture, clean and format. A new DB table needs to be created as well but this would be easy to script.

I like this solution since I still get to use the EPG and it looks just like the "stock" version of MP. WAF is high on this one.

At this point, there's two glitches:

1) my server does not import EPG data. I just re-enable the MP version every now and then.

2) VLC takes a second to connect to the stream and start pumping it out. If the client tries to connect to it too quickly, VLC goes to 100% CPU. I bumped to a 3GHz CPU but the real solution lies in properly implementing threading in the server I wrote.

I haven't even looked at recording functionality but I don't see it as being real difficult. Scheduling conflicts would be non-existant and the only limitation on how many channels could be streaming at the same time is your CPU and NIC bandwidth. This is written in Delphi, BTW.
