Hello everyone..

First I would like to say this is a great distribution.. I am fairly new to linux and am running Ubuntu linux on my main desktop.. I just set up knoppmyth on another box to run the backend and I am very impressed with the ease of installation and use. Kudos to everyone involved in creating this wonderful distribution.

I am having some difficulty with MythStream.. I have searched around the forums but I couldn't find a solution. here is whats happening

I click on Stream recordings and everything seems to go ok. but when I start the stream the only thing the log says is

Code:
Starting Stream of /myth/tv/1027_20051203220000_20051203230000.nuv
VLC media player 0.8.1 Janus
[00000214] main interface: creating httpd


now when I try to go to "my.ip:8001" I get a "Page cannot be displayed" errror.. and media player gives me an error that the server is not responding.

"my.ip:8002" works. but I can't figure out what to to with that screen.

any help is greatly appreciated

Thanks

Matt

can you see if any extra info is in log.txt file....default location is /myth/stream.

try running the script via an xterm window. go through the web interface as before....on the last screen you will see a 'Command Line' try that in an xterm

I assume you built ffmpeg and vlc from sources as listed on the instructions.

OK I get the exact same as above when I run it in Xterm
however when I ctrl-c to stop it it does display this message:

Code:
signal 2 received, terminating vlc - do it again in case it gets stuck
[00000218] main http daemon: httpd doesn't reference any host, deleting
mythtv@mythtv:~$


also here is my log file after starting it in the web interface, pressing the play button, and then pressing stop streaming:

also, you talk about building ffmpeg and vlc but I just installed mythtv from the cd.. the stream button was already there in the web interface.. is there some steps I am missing?

Thanks again for your help

Matt

[edit]

I just went through the web interface and tried pressing the play button and then immediately connecting with Windows Media Player, and I didn't get the host not responding message this time but instead got a message stating "Reached the end of the file"

ah, I forgot that streaming was included on the knoppmyth disk now...sorry about that.

my vlc output looks like this:

Code:
Starting Stream of /myth/1067_20051125003000_20051125010000.nuv
VLC media player 0.8.1 Janus
[00000214] main interface: creating httpd
[00000230] mpeg_audio packetizer: MPGA channels:2 samplerate:48000 bitrate:384
[msmpeg4 @ 0x835f51c]removing common factors from framerate
[00000231] mpeg_audio decoder: MPGA channels:2 samplerate:48000 bitrate:384


i always get the 00000230 message...with recordings and Live. I wonder if some thing is amiss with your audio components, or the audio in the stream.

what tuner board do you have?

Can you list the output of this command:
Code:
vlc -l

OK I have a MSI TV@nywhere Master card ..

I didn't think about that being a problem because I got it working in mythtv

but in order to get the audio to work I'll tell you what I did.

in /etc/modules I had to change qss=0 to the end of the tda9887 and commented out cx88xx and cx8800

now I put in the qss=0 first because that's what i had to put in ubuntu to get the cards audio to work and not just give me static. but in knoppmyth i still had static until i commented out cx88xx and cx8800.

However I did comment out both those lines at once and didn't check to see which one actually made it work right or if both actually needed to be commented out.. I'll test that out in a few minutes..

here is my output of vlc -l:

[edit]

ok uncommenting cx8800 gave me my static back so that needed to be commented out but i uncommented cx99xx and my sound still works.. so I've left that uncommented and tested the streaming again.. but still no go.. however I am wondering why the tv card would matter since I am trying to stream a file? this is a 1GHz AMD with 512mb ram that the backend is running on.

Thanks

Well, out vlc configs are identical.

some folks had to make adjustments to the way they are recording files in order for the audio to work.

I dont have a good answer. I'm not a vlc expert, rather more of a script/php writer.

I have two different backends on two different hardware configurations and I am having issue with vlc transcoding the .nuv files for VLC streaming.

I can play nuv files and get the video, on a linux box, suse box and windows box, but for the life of me, I cannot get any audio.

VLC shows there is a codec for video and one for audio (ac3).

I copied the nuv files to my pc and ran vlc locally, still no audio.

If, I do a nuvexport and convert the nuv file to mpeg, the mpeg stream has audio, so I know the nuv file has audio.

Any tricks I am missing? Google is not showing much direction.

I have installed ffmpeg from source, using the --enable options, installed transcode from source, installed vlc from source, etc.

I am using knoppmyth R5426.
HD 3000 HD card
Dell PE750 Server with 300 GB SATA for backend.

My frontends can play any recorded show or live tv from the backend with audio with no problems.

Thanks
