2bbf095e5b matroskamux: Simplify timestamp comparison logic in find_best_pad() 
If a buffer has no timestamp it is immediately muxed so we can directly break
the loop and simplify comparisons in the other cases.

a391728ad4 matroskamux: Don't time out in live mode if no timestamped next buffer is available 
The muxer can only advance the time if it has a timestamped buffer that can be
output, otherwise it will just busy-wait and use up a lot of CPU.

701f563996 matroskamux: Delay stream-header until all sink pads have caps 
If we don't wait, an incomplete header might be generated due to a race between
the _aggregate thread and the sink pad setcaps.

Fixes #3929

762a281b0c matroskamux: Include end padding in the block duration for Opus streams 
It has to be included in the block duration but in GStreamer we're not
including it in the buffer duration, so it has to be added again here.

Not including it in the block duration can lead to fatal errors when playing
back with Firefox if there are more padding samples than actual samples, e.g.

> D/MediaDemuxer WebMDemuxer[7f6a0808b900] ::GetNextPacket: Padding frames larger
> than packet size, flagging the packet for error (padding: {13500000,1000000000},
> duration: {6000,1000000}, already processed: false)

82b892ba3e matroskamux: Set rate/channels in Opus template caps 
For some reason these were missed, and if caps didn't have them, we would emit
an invalid Matroska file with a 0 value for Sampling Frequency or channels.

0f15580853 matroska: Fix AV1 alignment to TU 
Matroska stores AV1 in temporal unit, so that all OBU sharing the same
timestamp are put together. This was previously just assumed, which isn't
safe now that we have more alignments.

c6ba57eb8e matroskamux: allow width + height changes for avc3|hev1 
For avc3 and hev1, the intent was to allow more flexibility for caps changes
(see https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/-/merge_requests/1047/diffs?commit_id=9bd8d608d5bae27ec5ff09e733f76ca32b17420c)
however width and resolution were previously omitted.

avc3 and hev1 specifically support changing stream-parameters on the fly, whereas avc1/hvc1 disallow in-band SPS.

This commit allows for changes to width and height for these which is in line with matroskamux's behaviour prior to 1.14.0.

Practically speaking, one use case where this is commonly seen is when capturing a WebRTC stream, as the browser will adapt the resolution live.

9f798776e5 matroska-mux: Handle pixel-aspect-ratio caps field correctly when checking caps equality 
Not having this field is equivalent with it being 1/1 so consider
it like that. The generic caps functions are not aware of these
semantics and would consider the caps different, causing a negotiation
failure when caps are changing from caps with to caps without or the
other way around.

cebf769725 matroska-mux: If a stream has a TITLE tag, use it for the name. 
If a title tag is pushed to a pad, store it as the Track name.
This means that players will use it as the human readable
description of the track, instead of something generic like 'Video'
or 'Subtitle'
