56899b596e decodebin: Include codec description for missing plugins in the error message
If we had plugins and an error occurred we only include the error message
caused by this, otherwise we will include the codec description as generated
from the caps.

This allows to detect which exact codec was missing instead of getting a
generic "no suitable decoders found" error message.

14d79a3a47 decodebin: handle group switching for deadend group
Gracefully handle switching groups that all pads are deadend.

This can happen when quickly switching programs on mpegts as the
output is unaligned it can happen that not enough data was accumulated at
parsers to generate any buffers, causing the stream to receive EOS before
any data can be decoded.

To handle this scenario, the _expose function now also gets if there is
any next group to be exposed along with the list of endpads. If there are
no endpads and there is another group to expose it will switch to this next
group and then retry exposing the streams.

Also, the requirement to only switch from the chain that has the endpad had
to be modified to care for when the drainpad is NULL

b15a47aa19 decodebin: Link Parser/Converter directly and already connect to pad-added and other signals before setting elements to PAUSED
otherwise we're going to
a) start Parser/Converter before they are linked to their capsfilter,
   breaking their negotiation of a proper stream format
b) start demuxers without having connected to their pad-added signals. We
   miss pads and in the worst case don't link any pads at all

f66555668a decodebin: Only continue autoplugging once the pad has final caps
If the caps query returned us fixed caps this doesn't mean yet
that these caps are actually complete (fields might be missing).

element should be delayed as only complete caps allow proper selection

783195ccef decodebin: aggregate buffering messages
Aggregate buffering messages to only post the lower value
to avoid setting pipeline to playing while any multiqueue
is still buffering.

There are 3 scenarios where the entries should be removed from
the list:

1) When decodebin is set to READY
2) When an element posts a 100% buffering (already implemented)
3) When a multiqueue is removed from decodebin.

For item 3 we don't need to handle it because this should only
happen when either 1 is hapenning or when it is playing a
chained file, for which number 2 should have happened for the
previous stream to finish

2 seconds might be too small for some container formats, e.g.

long buffers. The video branch of multiqueue can run full while
the audio branch is completely empty, especially because there
are usually more queues downstream on the audio branch.

4f32010916 decodebin: Make sure that we always have a second multiqueue for adaptive streaming demuxers
For adaptive streaming demuxer we insert a multiqueue after
this demuxer. This multiqueue will get one fragment per buffer.
Now for the case where we have a container stream inside these
buffers, another demuxer will be plugged and after this second
demuxer there will be a second multiqueue. This second multiqueue
will get smaller buffers and will be the one emitting buffering
messages.
If we don't have a container stream inside the fragment buffers,
we'll insert a multiqueue below right after the next element after
the adaptive streaming demuxer. This is going to be a parser or
decoder, and will output smaller buffers.

6a699b6c40 decodebin: make it possible to register multiple handlers for autoplug-select
Change the way autoplug-select is accumulated so that it's possible to have
multiple handlers. The handlers keep getting called as long as they keep
returning GST_AUTOPLUG_SELECT_TRY.

One practical example of when this is needed is when hooking into playbin's
uridecodebin, which is perhaps not very elegant but the only way to influence
which streams playbin autoplugs/exposes.

5cd07bd2af decodebin2: only allow 'lower' multiqueues to emit buffering messages
When we have a scenario of demuxers linked to demuxers, decodebin2
will create multiqueue at different levels of the pipeline. The problem
is that only the lowest multiqueue's should do the buffering messaging,
as they will handle with the raw streams data.

When all multiqueues are doing buffering, the upper ones can handle
large buffers that easily fill them, moving from 0% to 100% from
buffer to buffer, causing too much buffering messages to be posted.
This hangs the pipeline unnecessarily and might lead to deadlocks.

6382d4c0ad decodebin2: do not handle the next-groups list as if it was a single item
Decodebin2's chains store a next_groups list that was being handled as
it could only have a single element. This is true for most of the
chaining streams scenarios where streams change not very often.

In more stressfull changing scenarios, like adaptive streams, those
changes can happen very often, and in short time intervals. This could
confuse decodebin2 as this list was always being used as a single
element list.

This patches makes it handle as a real list, using iteration instead
of picking the first element as the correct one always.

87fd43aaaa decodebin2: Fix group switching algorithm
There were two issues with the previous decodebin2 group switching algorithm:

Issue 1: It operated with no memory of what has been drained or not, leading to
multiple checks for chains/groups that were already drained.

Issue 2: When receiving an EOS, it only detected that a higher-level chain
was drained if it contained the pad receiving the EOS.

The following modifications have been applied:
- a new drained property has been added to GstDecodeChain
- both drained properties of chain/group are set as soon as they are detected
- the algorithm now tests agains these values

2f37ba60a2 decodebin2: Mark streams as complete on CAPS event but don't block
This allows the following use-cases to expose the group and pads
before an ALLOCATION query comes through:
* Single stream use-cases
* Multi stream use-cases where all streams sent the CAPS event before
  the first ALLOCATION query

Some cases will still make the initial ALLOCATION query fail though,
which isn't optimal, but not fatal (it will recover when pads are
exposed, a RECONFIGURE event is sent upstream and elements can
re-send an ALLOCATION query which will reach downstream elements).

e2a038acee decodebin2: Prune old groups before switching to the new one
In order to allow for proper functionality when a decoder only supports
one instance at a time (dsp), we must block the demuxer pads when they
get created if they are not part of the active group, preventing buffers
from being sent to the decoder (and initializing it through setcaps),
then after we switch to a new group, we unblock the demuxer pads for
the active groups. In the callback for the unblock, we prune the old
groups, making sure the previous decoder instance is destroyed before
we push a buffer to the new instance.

6b3e3544d4 decodebin2: Try harder to get initial topology caps
Since caps are no longer 'shared' between two pads (but forwarded from
source pad to sink pad) we end up with the first chain pad not having
specified caps (i.e. typefind:src).

This solves the issues by getting the pad's peer caps.

It is not optimal since it will (for most demuxers) return the pad
template caps, which might contain non-fixed caps (ex : with
qtdemux "video/quicktime; video/mj2; audio/x-m4a; application/x-3gp")

59f5d980f6 decodebin2: fix prerolling for low bitrate streams from hlsdemux
Such streams were detected as seekable, as the query on the typefind
element was testing the m3u8 file listing the actual streams, and
not going through the demuxer(s).

We now check for seekability for each multiqueue following a demuxer,
so the query will flow through the elements which might prevent seeking.
