I tested this last night on three different laptops, with three different reactions..

I have five different types of channel:

ATSC SD with ac3 audio
ATSC SD with mp3 audio (via steamdev / fmpeg and vdr-iptv - a cludge to allow my hardware mvp's to work)
ATSC HD with ac3 audio
a Hauppauge PVR HD, which works via pvrinput, H264, ac3 audio
PVR 500 anlogue MPEG2, mp3 audio

I loaded ac3filter to handle the audio on all PC's. All PC's also have

Laptop 1.  An Asus, with GMA900 graphics chipset, powerdvd 9 codecs..  Vista Ultimate  via WIFI..

Everything worked, but not well, lots of stuttering.  The h264 worked better than the mpeg2 ATSC HD stuff, but I think the bitrate would be lower.

PC Pentium 4 with Intel Graphics, XP..  Wired ethernet

This was the worst of the three. 

Selecting ac3filter crashed vompclient immediately.  I had to go to the server and manually edit the config file..

ATSC with ac3 audio stuttered horribly.
The reencoded stuff was a little better, but only a little..
H264 refused to play completely.
MPEG2 HD updated the picture about once every 10 seconds..

Laptop 3, ACER Aspire 5920G, Dual Core with Nvidia 8600 GFA.. Wifi..

This was nice and fast, and played everything, but the HD content was playing back wrong.. I think it was the vframe issue pointed out elsewhere, it looked like two videoprojectors were pointing at the same screen but one was out of sync slightly...

Recordings played back better than live tv..

Old HD MPEG2 ATSC recordings made under VDR 1.6 didn't play at all, but I think we knew that..

I am in the process of compiling a CVS hardware dongle so I can leave the cvs server code in VDR and the hardware mvp's will work.. Once done I will try testing again..

I noticed the media code was missing in the beta test..  Will that be missing in the latest cvs hardware version too?

Ooops, sorry, didn't notice some reply's..

Yes, sorry, it's ac3 audio not aac.

I am also using a Hauppauge PVR-HD which captures HD streams from component cables off my HD cable box in an h264 and either aac or ac3 stream..  Working with the pvrinput chaps to get this supported in VDR. We're almost there..

I am now using VDR 1-7-12, so if you want a TS stream I can give it to you..

(Lots of current Lost episodes in HD complete with commercials)..

IPTV plugin...

The plugin calls a script.  The script uses ffmpeg to pass the file back into vdr using a udp port.

Although I don't know if iptv supports h264..

Has anyone played with the playon.com windows software?  I am wondering about testing this within my xbmc environment.  After that I wonder how hard it would be to build it into my heavily modified test.sh script?  Anyone interested in working on this with me?

Am also wondering about intergrating get_iplayer into test.sh?  At the moment I have it running as a command line routined to bring up a vpn, download the show I want as an mp4 which media centre in vomp  can play.. and then drops the vpn//   However, it would be good to launch a routine which goes away, gets all the titles, retuens it as a list to vomp and then streams in realtime to vomp what you want to watch..

vdr-iptv is a plugin for vdr which converts an iptv stream into something vdr can handle as any other channel.  It has several modes, the most useful being able to call a script.  The script is responsible for getting the stream back to the vdr server as a udp packet stream. 

I use it to stream shows from bbc iplayer as I now live in the US. 

Hi Marten,

I got it working fairly well. Turned out I had two issues, ATSC uses only AC-3 audio and no regular audio, so them vompserver doesn't send it.  I got around it by using vdr-iptv and feeding the channel from streamdev, through ffmpeg to convert the audio to mp3 and back into vdr as another channel. That vomp can play and record.

The other was an issue with pvrinput for my analogue cable channels.  A patch to that enabled vomp to play them back.

I can send you an HD and SD ATSC stream if you want.  You can probably scp it off my server. 

I use a combination of vdr-iptv, mplayer and ffmpeg..

Install them all and then create a channels.conf for the station of choice:

Horribly messy, but it works, as the mediaplayer times out before the stream comes online..

I would like to send you some US ATSC HD Streams too, however, I have VDR 1.6,  this the VDR format.  This uses AAC audio, I would like to get this working if possible.

Thanks for the reply.  In the end I gave up and used IPTV to get it working..   However the 5 Second thing I can see would work..

I now have my US ATSC SD channels working.  It's quite convoluted but I will do my best to explain.  This procedure will also allow you to watch Internet Streams..

Theory
---------

ATSC streams only broadcast ac-3 audio.  Vomp cannot handle these streams so will not display the channels.  However, a VDR systems with the IPTV and Streamdev plugins can re-encode the channel using ffmpeg.

Requirements:
-------------------
VDR / Vompserver
iptv plugin (with quick patch if you want more than one "device".)
ATSC patch and plugin.
ATSC source. (and / or some URL's of internet streams).
ffmpeg installed on your system. 
Enough processor to re encode the stream "on the fly".  I have a Quad Core Phenom, so am not sure how much you need.

Problems
------------
Normally, with IPTV and VDR, when you stop watching a channel, SIGTERM is sent to the script which IPTV called.  This can be trapped in the script and ffmpeg can be killed.  However, on my setup, when using with Vompserver, the script ignores SIGTERM, so the IPTV patch sends SIGKILL, which kills the script, but not ffmpeg. If you watch another channel, the first is still being reencoded, so you will get a mash of both streams together which is not pretty.  I have hacked the script I call to run a little process in the background.  Every second it checks to see if the original script is still being run, if not it kills off ffmpeg and mencoder.

Howto
---------
Get ATSC working, and install the IPTV plugin.  Instructions for these can be found elsewhere.  IPTV requires the  pluginparam patch.

To use more than one IPTV device at a time, add  --plugin=iptv --devices=7  to VDR's command line, and the following patch to IPTV's source..  (thanks Rolf Ahrenburg for the tip).

NB, ffmpeg.streamdev is symlinked to ffmpeg.  I have done this for debugging purposes so I can find out what type of script called ffmpeg.

This will simply reencode the ATSC channel with MP3 audio.

If you want to watch an asx stream you need to add:

         mplayeropts="-playlist"

Under the PLX line in the Case structure.

These settings are US based (NTSC).  PAL ones would probably change resy to 576 and fr to 25.

Any questions, just ask.

A good source of urls for IPTV is to install XBMV and install the navi-xstreme script.  Then have a look through ~/.xbmc/scripts/Navi-X/cache/

If you're good at scripting you can process some urls before asking mplayer to get them.

Mplayer is better at getting streams than wget or curl.  Hence the dumpstream, fifo's etc..

One problem I had was udp didn't have enough buffer space and I got lots of dropped frames when watch streamdeved channels.

I ended up adding:

Code Select Expand

/etc/sysctl.conf
#Increase buffersize for udp
net.core.rmem_default=8388608
net.core.rmem_max=33554432


Which solved the problem.

I'm trying to stream BBC radio to the US.

My playlist is: bbcr4.radio

http://www.bbc.co.uk/radio/listen/live/r4.asx

I have added:

  Command.Name.29=/usr/src/vompserver-devenv/test1.sh
  Command.Extension.29=radio
  Command.Type.29=LIST
  Command.Name.30=/usr/src/vompserver-devenv/test1.sh
  Command.Extension.30=http-radio
  Command.Type.30=LIST

to vomp.conf

and :

Code Select Expand


    radio)
    convertradioList "$2"
    waitFkt
    ;;
    http-radio)
    fn=`echo "$2" | sed 's/\.[^.]*$//' | sed 's?^ */??'`
    createFifo
    convertradio_playlist "$fn"
    startReader
    waitFkt 1
    ;;

and

Code Select Expand


#convert a radio playlist
#handle http:// as radio-url
convertradioList() {
  cat "$1" 2>&1 | sed 's?^ *http:\(.*\)?/http:\1.http-radio?'
}

Finally, the stream calls:

Code Select Expand


convertradio_playlist() {

    url=`wget -q -O - "$1" 2>&1 | grep href -m 1 | awk -F \" '{printf $2}' | xargs echo`
    log url is $url
    log "create radio fifo"
    rm -fr /tmp/radio.wav
    mkfifo /tmp/radio.wav
    log "starting  mplayer -ao pcm:file=/tmp/radio.wav $url " 
    mplayer -ao pcm:file=/tmp/radio.wav $url > /tmp/mplayer.out 2>&1 &
    log "lame -b 192 -v /tmp/radio.wav $FIFO"
    lame -b 192 -v /tmp/radio.wav $FIFO >/tmp/lame.out 2>&1 &
    MPID=$!
}

Which almost works..

However, it takes a few seconds before the stream arrives.  I think medialauncher is killing it before it has a chance:

Any hints?  Avvdr?

Been thinking about this a little more.  In the US Teletext doesn't exist.  What about an option to change Teletext to Transcode.  You click the transcode button and the current stream is cat'd through a script like test1.sh?

I suppose this could be an optional button in case euro people want hd tv on their vomp's.

@avvdr

Yup, I already did that.  But it's not elegant and not granny proof (which is my criteria where I'm living at the moments (with the in laws having just relocated). ).

I have both stream and streamdev extension, one just cats the output to vomp, the other through mencoder.

Some mencoder ideas could be good as I don't think I get great quality, but it's good enough.
