Hi,

I wrote this but it doesn’t work. Instead it says source unknown and won’t work.

Can someone help me?

Log says:

HTTPStreamerAdapterSanJoseStreamer.onPlaylist: Stream not found [live/liveStream/manifest.f4m]: liveStream

and:

HTTPStreamerAdapterCupertinoStreamer.onPlaylist: Stream not found [live/liveStream/playlist.m3u8]: liveStream

and:
