Trying to understand some mediaplayer stuff (test1.sh)

[rdoac]

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?

After a long time....
not sure whether you are still working on this.
Currently for audio there is a fixed number of retries for reading data - in audioplayer.cc on the client side - MAXTRIES (counts in ~100ms units). This is set to 50 - meaning app. 5 seconds until the stream gets closed.
So first you should switch of the prebuffer delay (waitFkt without the "1" parameter).
But I guess you need at the end more then 5s as the wget takes already 6s.
So a dirty trick (if you cannot change the client) would be to feed initially some silence- sound into the pipe that lasts for a short time - the 5s start again after an receive - so maybe:

http-radio)
    fn=`echo "$2" | sed 's/\.[^.]*$//' | sed 's?^ */??'`
    createFifo
    cat silence.mp3 > $FIFO &
    bgpid=$!
    convertradio_playlist "$fn"
    kill -9 $bgpid
    startReader
    waitFkt

not tested - but only an idea...
The silence.mp3 should be only the time you typically need for the wget+setting up mplayer-5s+someSecureAddOn.

BTW: can't you use mencoder to avoid the second FIFO? - would make converting easier...

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..
