This should not harm regular files, since those are the last 4 bytes of
a normal file.
This allows to handle playback of concatenated mpeg-ps files. Seeking and
duration reporting is still wrong though.
Testing mpegversion when mpegaudioversion was likely meant.
Similar tests in sys/androidmedia/gstamcaudiodec.c also test
mpegaudioversion with the same conditional code.

This component is dereferenced, and later code checking for
NULL in particular cases implies it can be NULL. This likely
does not fix the coverity warning as it was seeing another
path setting component to NULL explicitely, but this was
spotted by looking at:

Which is actually OK from what I can see since the actual
dereference of the explicit NULL pointer will not happen
if the condition that led to the NULL pointer assignment
is met, since the assignment and defeference have mutually
exclusive tests.
Detect resolution changes on key frames, and propagate the resulting
caps to the src pad. Only the uncompressed data chunk is decoded, so
avoid using the new VP8 bitstream parsing library for now.

Avoid possible division-by-zero while deriving the presentation timestamp
of the buffer. The base class will take care of any interpolation needs.

* Search in current pending values first. For CBR streams we can very
easily end up having just one initial observations and then nothing
else (since the bitrate doesn't change).
* Use one group whether we are in that group *OR* if there is only
one group.
* If the group to use isn't closed (points are being accumulated in the
PCROffsetCurrent), use the latest data available for calculation
* If in the unlikelyness that all of this *still* didn't produce more
than one data point, just return the initial offset
While the calculation done in these macros will work with 64bit
integers, they will fail if working with 32bit integers.
Force the scaling up to solve that.
This amazingly didn't introduce major issues up to now, but resulted
in bogus values in debug logs.
Doing a hard flush on the packetizer will drop all observations, which
will eventually break push-based seeking (with BYTES segment) since
we won't know where to seek to anymore (new data would always be
considered as the beginning of the stream).
Turns out glib aborts on allocation failure, so this is pointless.
We'll just ignore Coverity warnings on such constructs.
This reverts commit d347809a82.
While this probably should never happen if callers are well behaved,
this avoids a crash if it does. With a warning about it. Unsure if
it'd be better to not add at all, but it should not happen...

While it will probably not trigger, it should silence a Coverity
warning about the fail code path testing for NULLness before
freeing, where the buffer was already dereferenced. It seems
safest to keep that test, in case future goto fail statements
happen to have a NULL buffer there.

Fixes multiple seeking issues. When doing ACCURATE or normal
non-KEYUNIT seeks, mxfdemux would just send data from the
edit unit that covered the seek position, whether that's
a keyframe or not. Decoders would only output things from
the next keyframe then, which means there's a gap between
the start of the segment and the first decoded data in
some cases. In combination with gst-editing-services this
might result in a frozen picture for the duration of that
gap at the beginning (if videorate fixes up the first
buffer's start timestamp to cover the entire gap), or
a black frame (if no videorate is used and videomixer
fills the gap). Also fixes A/V sync issue when requesting
a KEYUNIT seek.
