We know these values don't change during the loop, but the compiler
doesn't and has to re-check them for every iteration.

Multiple flvparse/flvdemux instances should be able to operate without
trampling over each other by accidentally re-using the same (static)
variables. (Spotted by Mark Nauwelaerts)

Do not confuse QtDemuxSegments with GstSegments when
comparing the total file duration with the segment duration

Fixes #610296

For calculating the durations of each sample, we are supposed to add each
duration modulo 1<<32 so make the elapsed time counter a uint32.

Fixes #610280

Make the handing of the mime type within the "boundary" a bit less naive.
The standard for MIME allows parameters to follow the "type" / "subtype"
clause separated from the mime type by ';'.

Modifies the multipartdemuxer's header parsing so it doesnt assume
the whole line after "content-type:" is the mime type and thus makes it a bit
more resilient to finding absurd mime types in the case where parameters are
added.

Fixes #604711

Check the task for NULL, it could be paused and set to NULL before.

ALAC codec-data apparently comes in (at least) two flavours (mov, mp4),
so use atom based parsing to retrieve required data, rather than
aiming for a specific offset.

See also #580731.

In particular, fixes non-flushing seek.

Look for a non-zero min_duration during initialisation to avoid
incorrect frame rate caps.

Helps to align with the loggin from libv4l.

Fixes #610053.

We don't want C specific flags in GST_CXXFLAGS, so base it on the
GST_CFLAGS that only contains the pkg-config CFLAGS but none of
the GST_OPTION_CFLAGS. Also, we only need the local includes once.
Fix typo as well (GST_FLAGS -> GST_CFLAGS).

pkg-config sets GST_CFLAGS and GST_LIBS. We need to use CFLAGS as a starting
point for for both C and CXX settings.

Remove some code where we pass ntpnstime around, we can do most things with the
running_time just fine.
Rename a variable in the ArrivalStats struct so that it's clear that this is the
current system time.

Use the running_time to calculate the jitter instead of the ntp time. Part of
the plan to get rid of ntpnsbase.

Don't calculate the NTP time based on the running_time of the pipeline but from
the systemclock. This allows us to generate more accurate NTP timestamps in case
the systemclock is synchronized with NTP or similar.

The compiler wants a cast here even though the type is already
typedefed as 64-bit integer (presumably because glib has typedefed
guint64 to unsigned long here).

None of these element and class structures are in public headers,
so don't need padding.

Fixes #609724.

Now the alpha is multiplied with the already existing alpha
value instead of simply ignoring it and the luma/chroma values
are kept, even if the output is 100% transparent.

From 96dc793 to 44ecce7

For GST_RIFF_TAG_JUNQ.

We silently ignore them instead of erroring out.

It was previously checking for DIFF(a, b > 6 * GST_SECOND) instead of
the proper DIFF(a,b) > 6 * GST_SECOND
