b3fe2d3623 videoaggregator: Fix locking around vagg->info
Take `GST_OBJECT_LOCK` when writing `vagg->info`, so that reading in
subclasses is protected against races, as documented in the struct.

    /*< public >*/
    /* read-only, with OBJECT_LOCK */
    GstVideoInfo                  info;

`gst_video_aggregator_default_negotiated_src_caps` should take the
`GST_VIDEO_AGGREGATOR_LOCK` to avoid racing with
`gst_video_aggregator_reset` called by
`gst_video_aggregator_release_pad` of the last sinkpad. Otherwise it can
happen that `latency = gst_util_uint64_scale (...` gets called with a
zero framerate.

There doesn't seem to be any reason not to use the local `info` instead
of `vagg->info`, so do that.

cb9799e942 video-converter: Skip input lines where possible.
There is a case where there are no lines in the temp cache, and
it's possible to skip straight to the request line and not generate
intermediate ones. This is really only beneficial when doing
nearest-neighbour downscaling, as other methods generally require
all input lines sequentially to generate the output. In that case,
this change has no effect and all lines are generated and cached
as before.

As a side effect however, this fixes corruption when downscaling
using nearest-neighbour, as interactions with the pass_alloc flag
and reuse of temporary lines causes the unecessarily-generated
cache lines to overwrite the final output.

9e37fa55bf gluploadelement: Avoid race condition of inside upload creation.
The operations for the inside GstGLUploadElement->upload have race
condition. The _transform_caps() will creates this object if it does
not exist, while the _stop() and change_state() can destroy this object.
The _transform_caps() is called by the gst_base_transform_query(),
so it does not hold the stream lock. It may use the upload while the
_stop() and change_state() has already destroy that object, and then
crash.

d268c193ad videoaggregator: Guarantee that the output format is supported
In the case `videoaggregator` is set as allowing format conversions,
and as we convert only on the sinkpads, we should ensure that the
chosen format is usable by the subclass. This in turns implies
that the format is usable on the srcpad.

When doing conversion *any* format can be used on the sinkpads, and this
is the only way that we can avoid race conditions during renegotiations
so we can not change that fact, we just need to ensure that the chosen
intermediary format is usable, which was not actually ensured before
that patch.

69b5cb8a10 video-aggregator: Fix renegotiation when using convert pads
Since 23189c60f4 we started using the
useless result of `modified_caps` which, was never used since it was
introduced 7 years ago (in videomixer2). The intersection is useless and
we should just avoid doing it at all (which was always the case before)
as it can end up failing renegotiation for bad reasons.

ad697e8f97 gl: optimize glcolorbalance by precomputing shader math
Precompute the rgb -> yuv conversion and color balance adjustment math
so that the shader does minimal work per pixel.

Merging these 15+ steps into 3 steps let us jump from choppy
360p video to smooth 720p video on our underpowered embedded system.

If we can remove the clamp() step inside the shader, or apply it after
rgba
conversion, there are more performance benefits to reap. But I am not
sure
what the side effects will be in that case.

c9d15fec7e glslstage: delete shader on finalize of stage
GLSLstage creates the glShader using glCreateShader, but never calls
glDeleteShader if the glShader is not used anymore. This forces the GL
library to keep the compiled shader around, because it might be used in
the future. Therefore, the glShader is leaked whenever a GLSLStage is
destroyed.

Fix the leak by deleting the glShader when finishing the GLSLStage.

ac72a6adaa gstrtpbuffer: fix header extension length validation
We validate the header extensions length of an RTP buffer by comparing
it against the block size. Since we multiply the length in words by 4 to
get the length in bytes, a suitably large length could cause a wrapround
of the uint16, giving a lower length which erroneously passes the check
and allows the buffer to be mapped.
