* ext/theora/gsttheoradec.c:
theoradec: Set telemetry options only if they are nonzero
Setting telemetry options, even to zero, causes libtheora to enable an expensive code path. For large enough videos (e.g. 1920x1080) this can increase the time to decode each frame by 30-40 ms, which can be enough to cause noticeable stutter.

* gst-libs/gst/gl/gstglslstage.c:
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.

urisourcebin: Fix crash caused by use after free
OutputSlotInfo doesn't hold ref of queue, so gst_bin_remove()
will free the queue memory.

* gst/typefind/gsttypefindfunctions.c:
typefind/xdgmime: Validate mimetypes to be valid GstStructure names before using them
On macOS, for example, "text/*" can be returned as mimetype for
plaintext files but we don't allow '*' in structure names and this would
cause critical warnings.
It's a valid mimetype but not a valid structure name.

* gst/playback/gsturidecodebin3.c:
uridecodebin3: Forward upstream events to decodebin3 directly
Otherwise default handler will try to forward it to sink element
or srcpad which might not be available at that moment.

* gst-libs/gst/video/video-converter.c:
video-converter: Add fast paths from v210 to I420/YV12, Y42B, UYVY and YUY2
These then don't require going through the generic code path via AYUV64
first but can be converted directly.
This speeds up processing of
videotestsrc ! v210 ! videoconvert ! other_format ! fakesink
by a factor of 1.55 for I420/YV12 and 1.40 for the other destination
formats and reduces memory pressure considerably.

videoaggregator: Limit accepted caps by template caps
This seems like an obvious mistake, since `modified_caps` was created
but not used.

* gst-libs/gst/rtp/gstrtpbuffer.c:
* tests/check/libs/rtp.c:
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.

* gst/playback/gstdecodebin3.c:
decodebin3: only force streams-selected seqnum after a select-streams
The initial streams-selected message might not match any select-streams,
in which case it is currently overriden with GST_SEQNUM_INVALID.

audio: video: Fix in/outbuf confusion of transform_meta
There are three instances where in- and outbuf have been swapped. This
didn't affect the correctness of the libs *filter code, but the
videoscale implementation swapped the arguments of meta->transform_func.

* meson.build:
build: use cpu_family for arch checks
e.g. on 32-bit arm, we may have armv6, armv7l, armv7hf, etc which all
generally have the same layouts. cpu_family() groups all of these into
just 'arm' that the ABI check table is expecting.

* gst-libs/gst/video/gstvideodecoder.c:
videodecoder: fix output state interlace-mode
When user is passing the actual interlace-mode when calling
gst_video_decoder_set_interlaced_output_state() it should not be
overidden by the input interlace-mode.
Needed to fix #825 as we want to keep interlace-mode=interleaved from
parsers and have the OMX decoder producing interlace-mode=alternate.

* gst/tcp/gstmultihandlesink.c:
multihandlesink: Don't pass NULL caps to gst_caps_is_equal
Apparently the sinkpad caps can get cleared when shutting down the
pipeline while the sink is working, provoking a critical warning.

* meson.build:
meson: Always wrap "prefix" option with join_paths() to make Windows happy
Both "\" and "/" separators are allowed on Windows but the problem
is that "\" is not converted to "\\" in this case.
It will result to unknown/unrecognized character escape sequence.

* gst-libs/gst/video/gstvideoaggregator.c:
videoaggregator: ensure peek_next_sample() uses the correct caps
gst_pad_get_current_caps() may be wrong when there is a renegotiation in
progress for the pad and we have not yet received or selected the buffer
with different caps yet.
Fix by storing the caps through in a similar way to the existing code
for buffer/video-info selection machinery.

2020-08-20 09:06:04 +0300 Sebastian Dröge <sebastian@centricular.com>

* gst-libs/gst/video/gstvideoaggregator.c:
videoaggregator: Don't require any pads to be configured for negotiating source pad caps
This is not actually required (anymore?). Source pad caps can be
negotiated at any time regardless of any configured (or existing) sink
pads and videoaggregator comes up with some fixated caps based on the
downstream caps.
Subclasses can override this behaviour as needed by overriding
update_src_caps().

* gst-libs/gst/video/video-color.c:
gst-libs: gl: Fix documentation typo and clarify gl_memory_texsubimage
`gst_gl_memory_read_pixels` reads pixels from `GLMemory` into the
pointer, effectively writing to it. This is opposite from
`gst_gl_memory_texsubimage` which reads texture data from `read_pointer`
into `GLMemory`.
Both cases are clarified by changing `read_pointer` to `write_pointer`,
and explaining what `gst_gl_memory_texsubimage` does in addition to
referring back to `gst_gl_memory_read_pixels`.

* gst-libs/gst/audio/gstaudioaggregator.c:
audioaggregator: Reset offset if the output rate is renegotiated
On next aggregation the new offset will be calculated based on the
segment position.
Without this a rate change would cause a jump forwards or backwards in
the output timeline.

video-anc: Implement transform functions for AFD/Bar metas
If the transformation is just a copy, copy over the metadata. For AFD
also copy over the metadata if the aspect ratio stays the same in
scaling transformations. In all other cases fail the transformation.
