We've been getting quite a few questions regarding HLS content problems. Most of them boil down to browsers not supporting TS segments. This CL adds a Q&A about it ti our FAQ. Change-Id: I7d5aa1c1a400df125880a6f8609d8b990bd33ad4

Frequently Asked Questions
Q: My live stream is buffering forever or doesn't play.
A: Check your time-sync. In v1 we would adjust automatically to account for
bad content. But now in v2, we don't. So this requires setting up clock sync
for live streams. This can be done by adding a <UTCTiming> element to the
manifest or by setting the .manifest.dash.clockSyncUri[1]
configuration option. See #386(comment) for more info.
Q: I am getting decoder errors or VIDEO_ERROR or error code 3016.
A: This error is given to us when the browser can't play the content. This
is out of our control and is usually caused by bad content. On Chrome you can
check chrome://media-internals for more info (see #489(comment)).
Q: I am getting HTTP_ERROR or error code 1002.
A: The browser rejected the request. Look at the browser logs for more
info. This is usually a CORS error. This is usually a matter of the correct
headers in the response. This can also happen with mixed-content restrictions.
If the site is using https: then your manifest and segments must also.
Q: I am getting LICENSE_REQUEST_FAILED or error code 6007.
A: See HTTP_ERROR. If you are getting a bad HTTP status, the server
rejected the request. Your proxy may require wrapping the request
or it may require extra authentication.
Q: I am getting INVALID_SERVER_CERTIFICATE or error code 6004.
A: You need to get the license certificate from your DRM provider. This is
not the HTTPS certificate of the proxy or any files on your proxy. This
should be the certificate of the license server given by your provider. The
certificate can only be used for that license server, but can be used with
different proxies so long as they use the same license server. For Widevine,
the certificate should be binary, so avoid fetching the response as a string
(e.g. with responseText).
Q: I am getting LICENSE_RESPONSE_REJECTED or error code 6008.
A: Check the DevTools network tab for the response. Verify that the response data looks correct. For Widevine, the response should be binary. If you see JSON, you will need to unwrap the response.
Q: My HLS manifest doesn't load.
A: If your HLS manifest describes MPEG2-TS content, the only browsers
capable of playing it are Edge, Chromecast and Safari. You will get an
UNPLAYABLE_PERIOD error on other browsers due to their lack of TS support.
We also were not able to make it work on Safari yet due to a bug in their
MediaSource implementation (#743).
Please file a issue if your TS content isn't playing in Chromecast or Edge
and your MP4 content - on any browser.
