bf57be7fc7 hlsdemux: fix reverse playback seek with snap flags
Properly handle snap flags during reverse seeking. In this case
the before/after are also reversed, so handle those as such.

For example: with a sequence of 1s fragments:

|-- 0 --|-- 1 --|-- 2 --|-- 3 --|

If you seek to 1.5s it is inside fragment 1. With reverse and

snap-before: should play from the end of fragment 1
snap-after: should play from the end of fragment 0

8be5551dff hlsdemux: fix potential error leak
Clear error as soon as we determine that the download failed,
otherwise there are code paths where we might return without
clearing it ever, which would leak the GError then. Also, we
can pass a NULL GError pointer to _fetch_uri(), so just do that
instead of passing one that we're going to just free again
right away anyway.

905158a055 hlsdemux: update current variant if connection speed is set
If connection speed is set, playlist according
to connection speed is selected as current playlist.

Problem is that the current variant of main playlist still
points to previously set variant.
If previously set variant doesn't correspond to current
playlist, then it causes unnecessary change of playlist
to the same playlist after first fragment is downloaded,
because of not updated current variant.

To fix this, we need to make sure that current variant
of main playlist corresponds to the current playlist

952275ad99 hlsdemux: When switching bitrate variants, don't jump back
Don't jump backward to 3 files from the end of the playlist
when switching variants - it just means we downloaded
fragments fast and caught up to the end of the playlist.

Disable that by treating a variant switch as a playlist
update, not a restart due to a seek or so.

fac4ed18d4 hlsdemux: Always give timestamps if we're discont and don't mark stream discont if a playlist change was not successful
If the stream is discont, we must provide a timestamp in any case. Elements
like tsdemux are not going to output anything if we give a NONE timestamp
after a discont.

Also marking a stream as discont if a playlist change was not successful would
lead to the above situation, but in that case we are not required at all to
mark the stream discont as we're still at the old playlist.

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)

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

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.

229a15b393 adaptivedemux: refactor chunk downloading flow
Add more power to the chunk_received function (renamed to data_received)
and also to the fragment_finish function.

The data_received function must parse/decrypt the data if necessary and
also push it using the new push_buffer function that is exposed now. The
default implementation gets data from the stream adapter (all available)
and pushes it.

The fragment_finish function must also advance the fragment. The default
implementation only advances the fragment.

This allows the subsegment handling in dashdemux to continuously download
the same file from the server instead of stopping at every subsegment
boundary and starting a new request

cd6069f5af hlsdemux: Don't use approximate duration for fragment buffer pts
The duration values in playlists are approximate only, and for
playlist versions 2 and older they are only rounded integer values.
They cannot be used to timestamp buffers.  This resulted in playback
gaps and skips because the actual duration of fragments is slightly
different.  The solution is to only set the pts of the very first
buffer processed, not for each fragment.

50b5d94b2a hlsdemux: Implement live seeking
hlsdemux assumes that seeking is not allowed for live streams,
however seek is possible if there are sufficient fragments in the
manifest. For example the BBC have live streams that contain 2 hours
of fragments.

The seek code for both live and on-demand is common code. The
difference between them is that an offset has to be calculated
for the timecode of the first fragment in the live playlist.

When hlsdemux starts to play a live stream, the possible seek range
is between 0 and A seconds. After some time has passed, the beginning of
the stream will no longer be available in the playlist and the seek
range is between B and C seconds.

Seek range:
start          0 ........... A
later               B ........... C

This commit adds code to keep a note of the B and C values
and the highest sequence number it has seen. Every time it updates the
media playlist, it walks the list of fragments, seeing if there is a
fragment with sequence number > highest_seen_sequence. If so, the values
of B and C are updated. The value of B is used when timestamping
buffers.

It also makes sure the seek range is never closer than three fragments
from the end of the playlist - see 6.3.3. "Playing the Playlist file"
of the HLS draft.

as that might not make sense. So always resort to flushing the
internal proxy pads by pushing flush events from the source's src pad.

Also as the seeking is not required anymore, only seek if there is
really a byte range to be used. And store a ref to the source's
src pad to avoid doing get_static_pad for every fragment.

940576244c hlsdemux: Do not push last buffer after error
In decryption scenario, a buffer is always stored to be sent later
to wait for more data or EOS to be able to strip the final bytes
if requested. In case an error hapenned this buffer can be ignored
and not pushed downstream.

Handle some more error cases:

1) When the source element fails to go to ready
2) When decryption fails
3) When there is no source to handle a specific URI
4) When the URI is invalid

4431388cab hlsdemux: handle errors from internal source
Set up a message handling function to catch errors from the internal
source and store the last return code to identify error situations
when returning from a fragment download.

Also moves the duration increase to after the download when we
know if it was successful or not

f16560c520 hlsdemux: Improve pad switching conditions
When using the internal source, hlsdemux doesn't know the caps of
the input before adding the pad, so remove the arguments that would
use that as it is always NULL.

And use an specific flag to signal when a pad switch is required.
Using the discont flag is a bad idea now because when a fragment
download fails it will lead to exposing a pad group without any
data, causing decodebin to abort.

As the buffers are directly pushed downstream and it

c93c222786 hlsdemux: re-enable decryption after uridownloader removal
Now the decryption is done buffer by buffer instead of on the
whole fragment at once. As it expects multiples of 16 bytes a
GstAdapter was added to properly chunk the buffers.

Also the last buffer must be resized depending on the value of the
last byte of the fragment, so hlsdemux always keeps a pending buffer
as it doesn't know if it is the last one yet

3611759557 hlsdemux: replace uridownloader with a GstElement
The GstElement is directly linked into a ghost pad and
its buffers are pushed as received downstream. This way the
buffers are small enough and not a whole fragment that usually
causes extra latency and makes buffering harder

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.
