Hi Chris,</div>

<div>
Thanks for the reply.</div>

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

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.</p>

I'm not sure how this differs from HLS though</p>

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

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