Hi Chris,

Thanks for the reply.

I'm not sure whether it's doing HLS (or indeed how to tell if it is or
isn't)...

  Is the enigma actually doing HLS? It's been a while since I looked
  at an enigma device but i thought it just offered up the transport
  stream.

  I'm not sure how this differs from HLS though

  Hi there,
  I've been hoping to simplify the process of integrating Myth and
  Enigma2
  based satellite receivers.
  I've been experimenting with the new HTTP Live Streaming feature of
  Myth
  0.26 with a hope to simplify the process of integrating an Enigma2
  based
  satellite receiver.  It feels as though the solution is within
  reach,
  but I'm not there yet.
  I started by creating a m3u playlist hosted on my backend containing
  streaming links taken directly off the Enigma2 box as follows:
  #EXTM3U
  #EXTINF:0,1 - BBC1
  #EXTMYTHTV:xmltvid=[3]london.bbc1.bbc.co.uk
  [4]http://enigma2_ip/web/stream.m3u?ref=1:0:1:189D:7FD:2:11A0000:0:0
  :0:&name=BBC%201%20London
  #EXTINF:0,2 - BBC2
  #EXTMYTHTV:xmltvid=[5]england.bbc2.bbc.co.uk
  [6]http://enigma2_ip/web/stream.m3u?ref=1:0:1:189E:7FD:2:11A0000:0:0
  :0:&name=BBC%202%20England
  The above was saved in /var/www and if I opened it using VLC I could
  switch between playlist entries and successfully play either
  channel, so
  then tried adding it to a freshly built test box running Myth 0.26
  broadly following the guide at
  ([7]http://www.mythtv.org/wiki/User_Manual:Setting_up_HTTP_Live_Stre
  aming_Recorder
  - thanks Jean-Yves for an excellent article).  I was able to
  configure
  the new card, source and scan for channels, but could not watch or
  record anything.
  After enabling verbose logging I could see there was a problem with
  my
  playlist as there was an 'unhandled url' error reported when I tried
  to
  record/watch a channel from my playlist.
  To verify that the problem was definitely with the playlist I'd
  created,
  I added the playlist listed in the wiki page above hosted by
  Jean-Yves,
  which worked.  I then also re-read and noticed the comment at the
  start
  of the wiki entry stating that "The link provided must be to a HTTP
  Live
  Streaming playlist", so I then modified my playlists so the main
  playlist (as referenced in the capture card) contained the
  following:
  #EXTM3U
  #EXTINF:0,1 - BBC1
  #EXTMYTHTV:xmltvid=[8]london.bbc1.bbc.co.uk
  [9]http://myth026_ip/bbc1.m3u
  #EXTINF:0,2 - BBC2
  #EXTMYTHTV:xmltvid=[10]england.bbc2.bbc.co.uk
  [11]http://myth026_ip/bbc2.m3u
  The two new playlists referenced above were as follows:
  #EXTM3U
  #EXTINF:0,1 - BBC1
  #EXT-X-TARGETDURATION:10
  [12]http://enigma2_ip/web/stream.m3u?ref=1:0:1:189D:7FD:2:11A0000:0:
  0:0:&name=BBC%201%20London
  and
  #EXTM3U
  #EXTINF:0,2 - BBC2
  #EXT-X-TARGETDURATION:10
  [13]http://enigma2_ip/web/stream.m3u?ref=1:0:1:189E:7FD:2:11A0000:0:
  0:0:&name=BBC%202%20England
  After trying to record again, the verbose logging looked a little
  more
  promising, as shown in the extract below:

  Running wireshark during the attempted recording shows an HTTP get
  request being sent to the Enigma2 box from the mythtv box, so it
  appears
  the structure of the playlist is sound, but the recording never
  seems to
  happen.
  I've run out of steam this evening, but any pointers would be
  greatly
  appreciated!!
  Cheers,
  Chris
