I have setup the example webserver that comes with the SDK (https://github.com/googlecast/), and it works will the example media file they provide. When I try it with an example m3u8 file it fails with:
{"code":"session_error","description":"LOAD_FAILED","details":null}`
Both URLs load fine in Safari. Is this type of streaming media not supported? Is there a way to get a more detailed error message.
