b47c92df82 hlsdemux: Set Referer in requests to the playlist URI 2014-04-28 10:04:28 +02:00
Tim-Philipp Müller
dbe6fdd6bf docs: remove outdated and pointless 'Last reviewed' lines from docs 
They are very confusing for people, and more often than not
also just not very accurate. Seeing 'last reviewed: 2005' in
your docs is not very confidence-inspiring. Let's just remove
those comments.

a06d4ea408 hlsdemux: Try reloading the playlist first if downloading a fragment fails 
But only add this for non-live playlists. For live playlists we already
have another thread that is periodically updating playlists.

Reason for this is that sometimes downloading a fragment can fail because
the URIs have changed or expired since last time.

864399f299 hlsdemux: When updating a non-live playlist make sure to find the current sequence by time 
Sequence numbers in different playlists are not guaranteed to be the same for the
same position, e.g. fragments could have different durations in different playlists.

In theory we should do exactly the same for live playlists, but unfortunately we can't
because doing this kind of seeking requires the complete playlist since we started
playback. For live playlists the server is however dropping fragments in the beginning
over time and we have no absolute time references.

c319b1cc8f hls: only set DISCONT flag on a valid buffer 
Recent refactoring causes this code to be called with either a NULL
fragment, or a non NULL fragment. In the former case, we don't have
a buffer. In the latter case, the original code dealing with DISCONT
assumed the buffer was valid. Testing for a NULL buffer here thus
does not seem to change the intent, and fixes:

b3a7242910 hlsdemux: Keep track of timestamps by adding them up during playback 
...instead of adding them from the start of playlist every time. This
among other things fixes timestamps for live streams, where the playlist
is some kind of ringbuffer of fragments and thus adding from the beginning
of the playlist will miss the past fragments.

a51116add3 hlsdemux: Refactor threading and downloading 
We now download fragments as fast as possible and push them downstream
while another thread is just responsible for updating live playlists
every now and then.

This simplifies the code a lot and together with the new buffering
mode for adaptive streams in multiqueue makes streams start much faster.

Also simplify threading a bit and hopefully make the GstTask usage safer.

73d9a8b0c9 hlsdemux: Start downloading the next fragment immediately after caching the initial fragments 
And only afterwards wait until a fragment was played. Otherwise we're keeping
our cache most of the time at "fragments-cache" fragments minus one.

Also allow setting "fragments-cache" to 1 now to start playback even faster.

4f04f3e68e hlsdemux: Start fetching new fragments whenever we have less fragments cached than given by the fragments-cache property 
Waiting until our cache is empty before starting to fetch the next fragment
kind of defeats the purpose of caching multiple fragments.

6799e3b879 hlsdemux: Prefer to use nettle for decryption but fall-back to libgcrypt 
nettle is used by newer versions of gnutls, while older versions of gnutls
used libgcrypt. Support both for now as not every distro has nettle yet.

nettle is preferred as it is more efficient to use and much smaller.

e8befb7ce3 hlsdemux: Use libgcrypt directly instead of going through gnutls 
gnutls is also just wrapping gcrypt, but we don't need any of
the TLS related functionality. We just need to be able to decrypt
AES128-CBC.
