MythTV v31, IPTV, REEBOX and redirects

Hello,

I'm trying to add some IPTV channels provided by my local fiber provider using the freebox tuner. I don't want all - just a handful so I've taken their .m3u file, modified it (to add the correct XMLTV information for the EPG from SchedulesDirect) and am hosting it locally.

VLC has no issue playing the streams. They are H.264 AVC and would seem to be compatible.

Here is the issue. The URL in the M3U includes a username and password. This is used by the IPTV provider to generate an authentication token and they then issue a 302 response to redirect the user agent to the final IP address, port and with a nonce-token (this token changes each time - and they cannot be reused).

The problem is when tuning the channel the frontend shows 'IL__ Partial Lock' but the channel times out. The backend log shows this:

Code: Select all

Finally - running tcpdump on the backend I can see that it's issueing the GET request to my provider - getting the 302 respponse with the correct 'Location' header to the stream endpoint - but the backend simply retries the original URL. It's not following the 302.

As mentioned - VLC has no trouble here.

Is there an easy fix for this?
