4e27245f28 libs: decoder: mpeg4: fail if return value is not OK
Coverity scan bug:

An assigned value that is never used may represent unnecessary
computation, an incorrect algorithm, or possibly the need for cleanup
or refactoring.

In the return value of decode_slice() or
gst_mpeg4_parse_video_packet_header() are not success, thus fail
decode_packet() function.

067968ae74 libs: decoder: h265: check for null
Coverity scan bug:

Dereference after null check: Either the check against null is
unnecessary, or there may be a null pointer dereference.

While looking for hte lowest poc, according to rest of the code, the
picture in the dbp (decoded picture buffer) might be NULL, thus we
could check for a NULL picture before assigned as found.

Also, split a comma operator because it is considered as a bad
practice because it possible side effects.

d879664a0a libs: decoder: h265: untaint loop control variable
Coverity scan bug:

Scalars (for example, integers) are not properly
bounds-checked (sanitized) before being used as array or pointer
indexes, loop boundaries, or function arguments are considered as
tainted.

In this case, num_nals were not checked before used as loop control.

9eddf6c004 libs: decoder: h264: remove unrequired NULL check
Coverity scan bug:

Dereference after null check: Either the check against null is
unnecessary, or there may be a null pointer dereference.

In the original commit for fill_picture_gaps() (commit 5abd2b90) the
prev_picture could be NULL, that's why the code did a null check. But,
since commit 52adebe7, the previous reference frames are tracked, thus
there is no need to check null anymore.

cdaf15b24d libs: encoder: h264: add multi reference support
Using num_ref_frames provided and the result of the Query
VAConfigAttribEncMaxRefFrames, it determines the size of reference list
and perform encoding with multi reference frames as the following:

1\ The num_ref_frames is being considered as the number of
reference picture list0
2\ Encoder adds 1 reference frame more to the reference picture list1
internally if b-frame encoding.
3\ If num_ref_frames is bigger than the number of refrence frames
supported in the driver, it will be lowered.

aa3543929b libs: encoder: h264: Add uncompliant mode reducing coded buffer size
Added a new property "compliance-mode", which default is the normal
strict compliant mode.

The second mode, "restrict-buf-alloc", is to limit the coded buffer
allocation size to improve performance in some specific Intel
platforms (there is asignificant performance improvement in parallel
encodings). Under this new mode, we use the MinCR field in A.3.1 for
pre-calculating the coded-buffer size.

02a6e9a273 libs: encoder: h264: insert AU delimiter
Insert an AUD as the first NAL of each encoded frame.

Some applications require Access Unit Delimiter for decoding the
stream.

The AU delimeter insertion is done only when the aud parameter is
TRUE (by default is disabled). The reason of this it is because this
header is only available from Intel Gen9 and the VA intel driver
should be 1.8 or superior. Otherwise, the output will be corrupted.

9b73b31c7a libs: encoder: h264: initialize all elements of view_ids
Currently when num_views is changed by multiview-mode on sink caps, it produces
wrong MVC encoded stream since the array view_ids is not set properly according
to changed num_views.

So this patch initializes all of the array sequentially to handle this case.
Side effect is not going to happen by this patch since this array is being
handled by num_views.

ca84fd211a libs: encoder: h264: set profile via capsfilter
Until now, the encoder ignored the profile in src caps and chose one
according with the given parameters. But the encoder must honor the
profile specifed in src caps.

This patch do that, and if the encoder needs to choose the profile,
it will do it by following these rules:

1\ If given parameters are not compatible with given profile, the
   encoder will bail out with an error.
2\ The encoder will choose the higher profile indicated in the
   src caps.

9397cd7d4d libs: decoder: h264: initialize active_sps/pps in reset
Since commits in https://bugzilla.gnome.org/show_bug.cgi?id=781142 landed,
they introduced regression in seek.

Formerly, once seek is done, decoder drops P-frames until I-frame arrives.
But since the commits landed, it doesn't drop P-frame and does try to
decode it continuously because active_sps is still alive. See ensure_sps function.
But there are prev_frames and prev_ref_frames reset already, then it
causes assertion.

So it's necessary to reset active_sps/pps also in reset method.

This is patch pretends to decouple the assignation of the values
in the parameter structures and the VA buffer's parameters setting.

It may lead to some issues since HRD, framerate or controlrate may
not be handled by the specific encoder, but they are set in
the VA buffer's parameters.

I leave as it because this patch is just a transitional patch.

daff4e9fbd libs: encoder: vp8: fix frame rate calculation
According to the VA documentation:

     The framerate is specified as a number of frames per second,
     as a fraction.  The denominator of the fraction is given in
     the top half (the high two bytes) of the framerate field, and
     the numerator is given in the bottom half (the low two bytes).

     For example, if framerate is set to (100 << 16 | 750), this is
     750 / 100, hence 7.5fps.

     If the denominator is zero (the high two bytes are both zero)
     then it takes the value one instead, so the framerate is just
     the integer in the low 2 bytes.

This patch fixes the the framerate calculation in vp8 encoder
according to this.
