I'm a little confused as to what you are tring to do. I think you want to connect a coax without a bablebox to a 250 and stream via vlc, is that correct?
that is the default way that mythstreamtv works. the vlc command has a parameter that is the frequency of the desired channel. if you are NTSC the frequencies are mapped with the scripts I provided. if you select channel 23, for example, the frequency 217250 is passed to vlc. The 250 is tuned to the correct channel prior to the start of streaming.
folks that use a settopbox to tune the channels need to leave the 250's settings unchanged but have the cable box channel adjusted...that is the extra step that was worked out later in the thread. majortom999, I dont think you need to worry about this.

Thanks for the reply, but I should clarify a bit.
I currently have a 2-tuner setup for Myth, and both are pvr-250's. One of the cards is connected to standard cable(video1). Streaming from that card is working, although I still have a few kinks to work out.
My second card(video0) is using the svideo in, from a cable box that is being controlled with an ir blaster. That is the one I'm trying to get to stream. In looking through the documentation for VLC, I've seen that it is possible, but appears to work on software encoding cards rather than the hardware encoding pvr-250's. It isn't actually clear about it though, so I was wondering if it is actually possible.
From the documentation:
Quote: channel=0 is the number of the channel (usually 0 is for tuner, 1 for composite and 2 for svideo)
But this is in the section that deals with the software encoding cards. See http://www.videolan.org/doc/streaming-h ... /ch10.html
Btw, nice job on this!

if you intend to stream form both, you will me to do some work. the Current stuff is coded to change the freq on the selected tuner card. There are details to change the script to 'not chantge the freq of the 250 but rather make an IRBlaster call'
It will be some work to make the script do one or the other depending on the card selected. probably not to bad, but some scripting will be required.

I was looking at that as well. I would actually be happy to just stick to the one tuner if I could get the svideo in sorted out, since that's the one connected to the cable box where the better programming is.
Ok, I'd be happy until it worked well then I'd go hunting for a new feature to add.
The channel change code for it looks to be relatively easy, my problem is still just getting it to work on the svideo in.

ah, you might need to change the 250's input to the correct s-video with the ivtvctl command.
This lists the
Code: ivtvctl --list-inputs This sets the input . try the s-video inputs listed above. My 250's list inputs 6-9 as s-video...not sure why there are 4 but I'm pretty sure you want 6 Try adding this to the script before the vlc call... Code: ivtvctl --set-input=6

Thanks, I'll try that as soon as I get home Tuesday and let you know how it works out. I'm on the road at the moment for our long weekend(Canada).

Pity you don't have it setup.

That point isn't lost on me. I worked all evening on it before I left trying to figure it out. It is mostly setup and working though, so I'm still doing well. For remote live tv I'm only missing some of the channels, since the normal cable tuner is working great for the live tv. Myth records the rest, and I use the normal Mythstream to watch those if I have time.

A solution to pseudo-live is to add a button to the 'stream a recording' page that scans ahead to 98% (inplace of +5 minutes). then you can start a recording via mythweb. go to Stream a Recording at anytime and jump to the end with the 98% button. (99% seems to cuase issues, probably since the file size is changing and the buffering required...playback seems to stop)
One of these days, when I get a chance, I'll rework some of the scripts. both install and runtime. Lots of great input has come from this thread.
I have been in touch with Joshua Ebel, the original Mythsrteamtv created, to join forces.
Here are some things I am thinking about. Any opinions, missing items...
Runtime
- Add better scanning controls - maybe a textbox for mins and % scan forward and back
- Change the settings form. instead of so many parameter selections...a single WAN/LAN selection. the Settings for LAN and WAN can be configured elsewhere.
- Create a configuraton form.
- Single click from 'Recorded Programs' (probably the thumbnail) to the streaming setting page Install - Point to ffmpeg and vlc DEBs created by trevarthan (is there a good place to host them?)
- handle IRBlaster/setop boxes better
- more automation
These are just some thoughts...that are waiting for free time.

R5a30.1
The Stream button is in mythweb and I have streaming working fine but I notice that Livetv is not an option. What steps are needed to get it working?
If I download the new version from sourceforge will that do it? Do I need to follow the intructions here including recompile etc or is a lot of this done.
I have 2x pvr250 cards would be happy streaming from the one connected to analogue cable.
Thanks
Craig

I have Mythstream TV working on my R5A22 backend box, and am watching the stream on a 2ghz IBM running Mepis with a Kaffine player.
It works fine except for the stopping to buffer every 35 seconds. Is this a 'network too slow issue' or a 'try Mplayer' issue ?
(No issues watching video on this machine with an A22 Knoppmyth front end...)

Whenenver I see buffering, it's due to network bandwidth. Are you seeing the buffering on your LAN or over WAN?
I upgraded my ISP service to have a double upload speed

It's on my intranet. The sender & receiver talk to each other over a 10/100/1000 switch, which is downstream of the router, so pretty stone simple.
Does a MythstreamTV stream have more throughput than MythTV to a front end ? (Which has no hitching problems..)

I'm not sure about the mythtv protocol betwen backend and frontend.
You can control the datarates that mythstreamtv uses on the configure screen...decrease the FPS or the size (% of full screen).
