In some cases, the PTS might be smaller than the first observed PCR
value which causes element to apply wraparound leading to bogus
timestamp. To solve this, we only apply it if the PTS-PCR difference is
greater that 1 second to be sure that it's a real wraparound.
Moreover, using unsigned 32 bits values to handle wrapover could end up
with bogus value, so it use pts value to handle it.
Also, convert pcr time to gst time before comparing it to pts.
Since refpcr is expressed in PCR time base while pts is expressed in GStreamer
time.

Enabling passthorugh mode is causing multiple issue:
For nal aligned multiresoluton streams, passthrough mode
make h264parse unable to advertise the new resoultions.
Also causing issues while parsing MVC streams which have two
separate layers (base-view and non-base-view).
This fix is only a temporary workaround.
For MVC, proper fixes needed in many places:
(handle prefix nal unit, handle non-base-view slice nal extension,
fix the picture_start detection for multi-layer-mvc streams etc)

Remove calls to gst_pad_has_current_caps() which then go on to call
gst_pad_get_current_caps() as the caps can go to NULL in between. Instead just
use gst_pad_get_current_caps() and check for NULL.

Set fallback channel layout on files with more than two
channels. Not clear where to retrieve the real layout from
or what the default layout is for AIFF files, the spec
only seems to specify some layout for up to 6 channels
and the file in question doesn't have a CHAN chunk.

This fixes a couple of issues regarding the output of (request)
per-program pads output:
We would never push out PAT sections (ok, that was one reallly stupid
mistake. I guess nobody ever uses this feature ...).
In the case where the PMT section of a program was bigger than one
packet, we would only end up pushing the last packet of that PMT. Which
obviously results in the resulting stream never containing the proper
(complete) PMT.
The problem was that the program is only started (in the base class)
after the PMT section is completely parsed. When dealing with single-program
pads, tsparse only wants to push the PMT corresponding to the requested
program (and not the other ones). tsparse did that check by looking
at the streams of the program...
... but that program doesn't exist for the first packets of the initial
PMT.
The fix is to use the base class program information (if it parsed the
PAT it already has some information, like the PMT PID for a given program)
if the program hasn't started yet.
In addition to the fact that it's a sane thing to do for multi-source
pad elements, it also avoids the situation where just using a request
pad (and not the main static pad) would result in the processing
stopping.
tsdemux is not able to handle negative playback rates.
But in mpegtsbase, the same check is not being done.
added a check to not handle negative rate while seeking unless
the same is handled upstream.

Since commit b77f8e172a the new value
assigned to mview_mode hasn't been used. That commit changed the following
"if" check to an "else if", which means the original value of mview_mode
is used.
When converting from avc to byte-stream, there will not be any codec_data
in the src caps. Remove it before the equality check to avoid sending caps
events downstream on every SPS/PPS change.

If we have a stream that contains an unchanging SPS/PPS for every video frame,
we don't need to to constantly query downstream for it's supported caps if the
current caps are compatible with the negotiated caps.

When the framesize is not specified, we try and calculate a size from
the strides and offset information. This was done with the sum of
offsets + the size of the last frame. That is just wrong method. We also
need to account for video meta that may be flipping two planes. An
example is if you convert I420 to YV12 by flipping the two last offsets.
https://bugzilla.gnome.org/show_bug.cgi?id=760270
To make parser work with image having non-standard strides, plane
offsets or with padding between images.
For now, since element doesn't check for videometa, we can't directly
push buffers when these properties are set so it convert the frame
in the pre_push_buffer method to remove any custom padding.

Allows the subclass to completely override the chosen src caps.
This is needed as videoaggregator generally has no idea exactly
what operation is being performed.
- Adds a fixate_caps vfunc for fixation
- Merges gst_video_aggregator_update_converters() into
gst_videoaggregator_update_src_caps() as we need some of its info
for proper caps handling.
- Pass the downstream caps to the update_caps vfunc

When sps data is NULL, the buffer allocated and mapped is not being freed.
In this scenario there is no need to allocate the buffer as we are supposed to return NULL.

It's useful enough already to be used in other elements for audio aggregation,
let's give people the opportunity to use it and give it some API testing.
