ea5de0d757 videoaggregator: Switch to a GstVideoAggregatorConvertPad subclass
This moves all the conversion related code to a single place, allows
less code-duplication inside compositor and makes the glmixer code less
awkward. It's also the same pattern as used by GstAudioAggregator.

83192bce84 videoaggregator: Move aggregated_frame and the pad buffer into the private struct
The aggregated_frame is now called prepared_frame and passed to the
prepare_frame and cleanup_frame virtual methods directly. For the
currently queued buffer there is a method on the video aggregator pad
now.

89a85732d4 tsdemux: ignore sparse stream when checking for initial timestamp
Unless we only have sparse streams. In this case we will consider them.
It fixes a bug happening when first observed timestamp comes from a
sparse stream and other streams don't have a valid timestamp, yet. Thus
leading the timestamp from sparse stream to be the start of the
following segment. In this case, if the timestamp is really bigger than
non-sparse stream (audio/video), it will lead the pipeline to clip
samples from the non-parse stream.

0869c06f9d scenechange: improve detection algorithm
Scene detection determines, how many scenes have changed in a video.

It compared the previous frame with present frame to find out the score and a
threshold is calculated for the same.

I have added an intermediate condition which helps in improving the positive
detections.

ede8b1c8ce rfbsrc: Fix decide_allocation to support NULL pool
We were assuming that NULL pool meant that downstream didn't reply.
Update the pool index 0 instead of adding at the end. Otherwise we ended
up letting basesrc decide, which would pick the blocksize as a size
(4096) instead of the image size.

a9ac937be5 testsrcbin: fix bug setting stream flags
We would mark all streams with FLAG_UNSELECT as we would check
the pointer for non-NULLness not the dereferenced stream number
(and the pointer is always non-NULL). The intention here was
presumably to mark the first stream of each type as SELECT and
the others as UNSELECT by default.

4984af5917 debugutils: Add a testsrcbin element
This is a simple Bin that will expose audiotestsrc or videotestsrc
based on what is asked by the user either through the GstURIHandler
API or through the "stream-types" property.

This element also provides GstStream and GstStreamCollection
so it is nicely usable from playbin3.

53d7a1298c pcapparse: bail out in case of fragmented packets
pcapparse cannot parse fragmented IP packets correctly, in particular it
will get confused when trying to parsing fragments as standalone frames
in two ways:

  1. the first fragment will have the packet length greater than the
     frame size and will always be discarded;

  2. fragments with non-zero offsets will be interpreted as full packets
     and the first part of their raw payload data will be parsed as the
     transport protocol header, resulting in bogus values for addresses
     and ports, thus evading the properties filtering on those values.

This can make it difficult for users to see why the data does not get
downstream.

So be more explicit and just bail out when fragmented packets are
encountered.

9cd77b1644 fakevideosink: request an extra buffer if enable-last-sample is enabled
If the 'enable-last-sample' property is enabled, fakevideosink will keep
a reference on last rendered buffer which may lead to buffer starvation
in the pipeline.
Request one extra buffer in this case so we always have a buffer flying

streaming starts, so before we chain up to the parent
class in the state change function. And when we shut
down the element, we need to reset things after streaming
has stopped, so after we chain up to the parent class
in the state change function.

d252f503fc h265parser: decouple GstH265Profile and GstH265ProfileIDC
We used to have the same enum to represent H265 profiles and idc values.
Those are no longer the same with extension profiles defined from
version 2 of the spec.
Split those enums so the semantic of each is clearer and we'll be able
to add extension profiles to GstH265Profile.

Also add gst_h265_profile_tier_level_get_profile() to retrieve the
GstH265Profile from the GstH265ProfileTierLevel. It will be used to
implement the detection of extension profiles.

3fb81536ce audiolatency: New plugin for measuring audio latency
Measures the audio latency between the source pad and the sink pad by
outputting period ticks on the source pad and measuring how long they
take to arrive on the sink pad.

Very useful for quantifying latency improvements in audio pipelines.
This plugin was particularly useful during development of the
low-latency features of the wasapi plugin.

3cf4a70dbc pnm: Fixed segfault in pnmenc
The pnmenc was not mapping the input buffers as video buffers. Because
of this, the video frame stride was not being set based on frame but
based on the caps, which make the assumption that the strides are a
power of 4. For input that is not a power of 4, this would lead to a
SIGSEGV.

ec963e688f interaudio: Make sure both PTS and DTS values are defined
The inter plugin originated in 0.10, which had only one timestamp. As a
result, during the port to 1.0, the DTS were left undefined. This can cause
subtle bugs with basesrc, which can end up incorrectly picking DTS over PTS
and producing output buffers with incorrect timestamps.
