Hi,
I'm working on a plugin that is scraping a page for video links to live video. I've got the scraping working, and the links are functional if I try to play them as a network stream in VLC. When I try to play them through XBMC however, I get errors and they fail to play. The relevant part of the log is here:
Specifically the error seems to stem from curl and its requirement for being able to request byte ranges. I imagine this is an issue for live video, since typically you're downloading chunks as they're available. Is there some way to get XBMC to do live video playback or does the plugin itself need to manage downloading chunks and feeding them into the XBMC player? If so, could anyone point me to some resources on how that could be accomplished?
