pvr.nextpvr uses  XBMC->OpenFile() to read http streams to ts data and it works fine, however when I pass an m3u8 (which is the NextPVR transcoded interface returning HLS application/x-mpegURL files) the stream immediately fails

I am assuming this is because it doesn't know how to read m3u8 files.  Are there are parameters that can be passed or appended to the stream to assist. I tried |reconnect=1  etc don't seem to change the parameters.

I did see that pvr.iptvsimple has some logic to help set stream properties https://github.com/kodi-pvr/pvr.iptvsimp...t.cpp#L241  but it not clear what documentation I need to read to use those properties.

Thanks,

I believe the issue might be related to the relative links  in the m3u8 file being returned

Code:

Instead of calling the source base URL as expected (which works via python)

'http://172.16.3.105:8866/temp/CNN-18544c1ac8d14f5f8ec0359bb2a91a510.ts?sid=8a3195b0a8f749e996ebbe8eeb30abdd'

it is calling

Is there a method I can use to have this function open a ts stream from a relative URL? 

It isn't just the NextPVR m3u8, any m3u8 file that has segments not starting with http seem to have this issue.  If I pass an m3u8 with an absolute reference it works.

So comparing with detailed logging  if I hardcode an m3u8 that has  absolute links in OpenLiveStream() it works.   I guess there is no way to pass back the base url to get this too work.

I think the only way I can do this is to send the m3u8 in properties similar to pvr.iptvsimple and provide two logic paths.  It is a pain because there is no Close()  method where I can tell the backend to stop transcoding and it looks like the m3u8 file keeps being streamed as I change channels.

Alternate solutions are welcome.
