8b4db06733 rtpmp4vpay: Increase ranking
Both rtpmp4vpay and rtpmp4gpay support MPEG4 elementary streams. But
the most supported variant is the video-specific one (rtpmp4vpay),
therefore increase the rank of that one so that auto-plugging of
payloaders for MPEG4 elementary streams ends up picking that one
and not the generic one.

9d6621a30d matroskademux: implement keyframe search also without cluster prev size
If we have cluster prev size (GStreamer muxer will write it by default),
we can go back to the previous cluster efficiently, but if we don't then
just search backwards until we find a cluster ebml identifier, like we
do when searching for clusters in the bisection loop.

2d6efbbae2 matroskademux: make max backtrack distance for keyframe search configurable
Add property instead of hardcoding it in the code.

In some scenarios such as CCTV variable fps and extra long GOPs are
used to minimise storage space, for example. In those cases there might
not be any keyframes for many minutes, so provide a property to override
the max allowed distance.

ffb4533137 matroskademux: no need to search for keyframes for intra-only streams
If the video streams are all I-frame only then we don't need to look
for a cluster with a keyframe, we can just assume there will be one.

694631520d matroskademux: figure out if we have prev_size when starting up
This is useful to know in case someone initiates a seek or
direction change before we reach the second cluster.

43ce85f794 matroskademux: try to ensure keyframe when seeking without index
When seeking in pull mode without an index (because there is no index
or the file is still being written to) we bisect to find the right
cluster to jump to. However, it's possible the cluster we found doesn't
start with a keyframe, which leads to decoding errors, so if we know
that the found cluster starts with a delta frame try to scan back to
previous clusters until we find one that starts with a keyframe or
we are back at the beginning. Theoretically it's possible that all
clusters but the first one do not start with a keyframe and the
keyframes are in the middle of clusters, but this is extremely
unusual, so we will cover this case with a basic sanity check.

This problem is especially problematic with content recorded with
dynamic GOP and FPS, where long GOP lengths and low FPS may cause a
large set of clusters to lack key frames. Playback would then be
started on a non-keyframe cluster, and the large number of such frames
would make the content impossible to decode fo a long stretch of time.

93ddea2a70 matroskademux: extract cluster prevsize if available
This is useful for reverse playback/trickmodes
without an index, and will also be useful in the
seek handler if we need to scan back to find a cluster
that starts with a keyframe.

c61bcb1fd2 udpsrc: Balance Linux value of get/set_rcvbuf
On Linux, the kernel returns twice the size as it will allocate extra
space for accouting. We devides this value by two in order to ensure
that get/set value now match. This fixes the set buffer size validation
and allow having a nice warning when the size if surpassed and the
process does not have CAP_NET_ADMIN capabilities.

9b4a022dee updsrc: set udp buffer size forcibly
The udp buffer size is limited to a maximum of around 100K.
Some apps need to set the force bufsize for their own operation.
Use the SO_RCVBUFFORCE option in order to override the rmem_max limit
of linux kernel. Require user to have the CAP_NET_ADMIN privilege to
work.

f8076e208b splitmuxsink: Fix reference counting loop
The stream context was holding a reference to the
internal queue and pads, with pad probes that were
in turn holding references to the stream context.

f672116c72 splitmux: Improve handling of repeated timestamps

here.

025a430d08 qtdemux: rework segment event pushing, again
This patch aims at fixing the recent regressions in the adaptive test
suite.

All segment pushing in push mode is now done with
gst_qtdemux_check_send_pending_segment(), which is idempotent and
handles both edit lists cases and cases where the upstream TIME segments
have to be sent directly.

Fragmented files that start with a non-zero tfdt are also taken into
account, but their handling has been vastly simplified: now they are
handled as implicit default seeks so there is no need to extend the
GstSegment formulas as was being done before.

qtdemux->segment.duration is no longer modified when
upstream_format_is_time, respecting in this way the durations provided
by dashdemux and fixing bugs in reverse playback tests where mangled
durations appeared in the emitted segments.
