6f95f7263f mpegts: don't shadow res variable
Fixes unused-but-set warning:

95ff949eff mpegtsmux: Start last_ts with GST_CLOCK_TIME_NONE
And use the output segment position for the outgoing timestamp while it
is. This is needed to delay the calculation of `output_ts_offset` until
we actually have a usable timestamp, as tsmux will output a few initial
packets while `last_ts` is still unset.

Without this, the calculation would use the initial `0` value, which did
not have the intended effect of making VBR mode behave like CBR mode,
but always calculated an offset equal to the selected start time.

e5dbf86a54 mpegtsmux: Use GST_CLOCK_STIME_NONE for output_ts_offset
It's a GstClockTimeDiff, thus GST_CLOCK_TIME_NONE isn't appropriate.

7cebd5b359 tsmux: Skip empty buffers
They can be created e.g. by aggregator when there is a gap. Such buffers
should not be muxed at all.

2f7ec968f4 tsmux: Allow specifying PMT order via the prog-map
Look for an entry `PMT_<PID>` in the `prog-map`, which specifies the
relative index of the stream in the PMT.

320bc6362b mpegtsmux: Avoid crash when best pad gets flushed
The 'best' pad might receive a flush event between us picking it and us
popping the buffer. In this case, the buffer will be missing.

c2eeb639b0 basetsmux: fix SCTE pts_adjustment with offsets
When there are elements between the demuxer and the muxer that
introduce an offset to the running time, or when offsets are
set on pads by the application, this shift must be taken into
account when calculating the final pts_adjustement.

c3a161f287 basetsmux: rework SCTE section handling to handle passthrough
mpegtsmux can receive SCTE sections from two origins: events
created by the application, and events forwarded downstream by
mpegtsdemux, containing sections that may not have been fully
parsed, and additional data to help tsmux translate times to
the correct domain, both for requesting keyframes and calculating
an accurate pts_adjustment.

The complete approach is documented further in a comment above
the relevant function.

be4d0fff23 basetsmux: extend SCTE 35 support
Makes it possible to support passing SCTE 35 cue points from
demuxer to muxer, while preserving correct timing.

This will also improve ex nihilo cue points injection, as splice
times and durations are now interpreted as running time values,
and may trigger key unit requests.
