e0b4290998 hlsdemux: don't crash or leak memory on broken master playlist
If a (master) playlist contains a variant list entry without a
URI then during parsing of the next variant list entry we are
a) leaking the entry we're currently parsing (new_list), and
b) free'ing the pointer to the previous list entry (list) without
   updating the pointer.

Hence when then adding the URI for the latest parsed entry, incorrect
information is stored, as the information is used from 'list' which
is not valid memory anymore, also leading to crashes.

Fix this by correctly storing the new variant list entry pointer
as needed.

1c8d844ece hlsdemux: m3u8: move file lookup by sequence directly into code
Nicer to read, two lines of code less, and also the callback
function should've been a GCompareFunc that returns a gint
and not a boolean (it did work correctly, was just confusing).

f7c4bb5ac6 hls/m3u8: Update current position in all cases
In order to ensure the sequence_position will always be consistently updated,
store the current file duration.

This way, when we advance, we can always increment the position based on what
was previously outputted.

d5f79b8529 hls: if media sequence is not specified, use 0
Allows playlists that are missing the mediasequence information to
be correctly parsed. If the playlist was updated without reseting
the mediasequence it would constantly increase over subsequent updates,
leading to issues during playback.

8d86a8b75d hlsdemux: Avoid negative sequence numbers
For live streams, we want to make sure there's a certain distance
between the sequence to play and the last (earliest) fragment.

The problem is that it assumes there are at least 3 fragments in
the playlist, which might not always be the case (like in the case
of a server restarting and gradually adding fragments).

In order to avoid ending up with negative sequence numbers (which
will just loop forever), limit the new target sequence number to
the highest of:
* either the first sequence number of the playlist (fallback)
* or 3 fragments from the last one (standard behaviour)

22456ce032 hlsdemux: select correct position for live streams that don't remove fragments
Some live streams (eg youtube) don't remove fragments in order to allow
seeking back in time (live + vod).

When gst_m3u8_client_has_next_fragment is called, we are getting wrong fragment
because current_file points in first file of the fragments list resulting in
watching the stream from the beginning again.

This patch sets current_file to nth fragment for live streams, then on
gst_m3u8_client_has_next_fragment will keep up with the live stream.

581d8c0b8d Revert "hlsdemux: Simplify logic in process_manifest"
This reverts commit 4ca3a22b6b.

The connection-speed=0 is used as a special value in the property
of hlsdemux to mean 'automatic' selection, m3u8.c doesn't need
to know about that as it should be as simple as possible.

So this patch hides this automatic selection documented in hlsdemux
into m3u8 logic and I think the gets harder to understand the code.

It also makes the hlsdemux unit tests work again

04b010a883 hlsdemux: Search more when advancing fragment
In live situations, it is not uncommon for the current fragment to end
up out of the (updated) play range (lowest/highest sequence). But the next
fragment to play *is* present in the play range.

When advancing, if we can't find the current GstM3U8MediaFile, don't abort
straight away. Instead, look if a GstM3U8MediaFile with the next sequence value
is present, and if so switch to it.

bb36ffb633 hlsdemux: Fix how the playlists are refreshed
We should only refresh the currently selected variant playlist (if any,
otherwise the main playlist), not the main playlist. And only try to
refresh the main playlist if updating the variant playlist fails.

Some servers (Wowza) use the request of the main playlist to create a
"session", which is then part of the URI of the variant playlist and
also the fragments. Refreshing the main playlist would generate a new
session, and the server rate limits that usually. And after a few retries
the server just kicks us out.

Also as a side effect we now use the same downloader for all playlists, so
that we only have 2 instead of 3 connections to the server. And also
previously we just ignored the downloaded data from the main playlist that
the base class gave to us.

86a503a29b hlsdemux: handle too short segments
When the segment is very short it might be the case that the
typefinding fails and when finishing the segment hlsdemux would
consider the remaining data (pending_buffer) as an encryption
leftover.

This patch fixes it and makes sure an error is properly posted
if typefind failed by refactoring buffer handling to a function
and using it from the data_received and finish_fragment functions.

f00aec48fa hlssink: implement a chain_list to request key unit for segments
upstream might send buffer lists instead of buffers and hlssink's
probe won't get called and a new segment won't be created when needed.

This patch fixes it by adding a chain_list function to the sink pad
that will just pass through the whole bufferlist if no segment needs
to be requested at the moment or convert the list into buffers to
check the proper timestamp to request the next key-unit that will
start the segment.

a08dd85608 hlsdemux: select correct starting position for live streams
When playing live HLS streams, the media playback starts from the
beginning of the media playlist. When playing a live HLS stream,
media playback should start from 3 fragments from the end of the
playlist.

See section 6.3.3. of the HLS draft [1]

This commit changes the logic to select 3 fragments from the end when
playing a live stream.
