14cd8b8348 leaks: Do not trace refs for object we do not follow
When the user sets filters, we should not trace ref counts of object that
are not traced. This optimizes the tracer by potentially avoiding
generating useless backtraces.

733246f1b4 bus: Make setting/replacing/clearing the sync handler thread-safe
Previously we would use the object lock only for storing the sync
handler and its user_data in a local variable, then unlock it and only
then call the sync handler. Between unlocking and calling the sync
handler it might be unset and the user_data be freed, causing it to be
called with a freed pointer.

To prevent this add a refcounting wrapper struct around the sync
handler, hold the object lock while retrieving it and increasing the
reference count and only actually free it once the reference count
reaches zero.

As a side-effect we can now also allow to actually replace the sync
handler. Previously it was only allowed to clear it after initially
setting it according to the docs, but the code still allowed to clear it
and then set a different one.

412e97beb4 caps: keep ANY caps empty internally
Keep the ANY caps empty internally when appending and merging
caps/structures. Previously, an ANY caps could end up containing
internal structures, which could be fetched by the user, and gave the
caps a non-zero length.

Also, made sure that `gst_caps_set_features_simple` frees the features
if caps is empty.

407e32588d caps: fix is_strictly_equal
Fixed gst_caps_is_strictly_equal() to take into account whether either of
the caps are ANY caps. Previously, two ANY caps could be considered not
strictly equal if one of them still contained some remnant *internal*
structure (this can happen if an ANY caps has emerged from an append or
merge operation). Also, an ANY caps with no remnant internal structures
was considered strictly equal to an EMPTY caps. Similarly, a non-ANY caps
was considered strictly equal to an ANY caps if its remnant internal
structures happened to match.

Also changed gst_caps_is_fixed to take into account that an ANY caps
should not be considered fixed even if it contains a single remnant
internal fixed structure. This affects gst_caps_is_equal(), which uses a
separate method if both caps are fixed. Previously, this meant that a
non-ANY fixed caps was considered equal to an ANY caps if it contained a
single matching remnant internal structure.

Added some tests for these two equality methods, which covers the above
examples, as well as asserts existing behaviour.

baa5aae24b baseparse: Don't set meaningless buffer dts from segment->start
When we do not have any information about DTSs we shouldn't try to make
them up, moreover after seeking `segment->start` has nothing to do with
the next buffer timing (and is probably after the actual buffer timestamp)
and since, since fa8312472f
we do:

```
if (buffer->dts > buffer->dts)
    buffer->pts = buffer->dts
```

we end up setting `buffer->pts = segment->start` which is plain
broken and leads to downstream decoder accept the first buffer
as it will be inside the segment (its pts==segment->start) which
basically means accurate seeking behaves mostly the same way as
keyframe seeks.

216d6dd0f0 GstSystemClock: Add GST_CLOCK_TYPE_TAI
GST_CLOCK_TYPE_TAI is GStreamer abstraction for CLOCK_TAI. Main
motivation for this patch is support for transmission offloading features
- when network packets are timestamped with the time they are deemed to
be actually transmitted. Linux API for that requires that time to be
in CLOCK_TAI coordinate.

With GST_CLOCK_TYPE_TAI, applications can use CLOCK_TAI directly on
their pipelines, avoiding the need to cross timestamp packet times. By
leveraging system's CLOCK_TAI, applications also don't need to keep track
of leap seconds - less burden for them. Just keep system's CLOCK_TAI
accurate and use it.

47765e164b bin: Don't consider having a group-id or being STREAM_START if we have not a single STREAM_START message
This would cause us to set GST_GROUP_ID_INVALID as group-id in the
aggregated STREAM_START message if there are no sinks at all or none of
them have a STREAM_START message, which is simply wrong.

If we have not a single STREAM_START message then the bin should not be
considered STREAM_START.

Errors causing the pipeline to fail going from NULL to PAUSED
were not displayed, and the pipeline was not dumped either in
those cases.

the dump matches exactly the state of the pipeline at the

52706146f5 pluginfeature: Allow updating initial rank of plugin feature
Introducing "GST_PLUGIN_FEATURE_RANK" environment variable in order for users
to adjust rank of plugin(s) via environment.

A "feature" and "rank" key-value pair should be separable by ":",
and each key-value pair is recognized per "," delimiters. The rank
can be a numerical value or one of pre-defined rank values
such as "NONE", "MARGINAL", "SECONDARY", and "PRIMARY" in case-insensitive manner.

In addition to pre-defined { NONE, MARGINAL, SECONDARY, PRIMARY },
"MAX" can be passed to key value used to ensure having a higher rank
than other plugin features.

Example)
- GST_PLUGIN_FEATURE_RANK=qtdemux:256,h264parse:NONE
Set rank of qtdemux plugin to 256 (primary) and 0 (none) for h264parse.

72daeee2c4 gstinfo: Add new API for getting debug log lines
If you're using a custom log handler, you had to reverse-engineer the
debug log format and create your own format function. Now, you can
call `gst_debug_log_get_line()` and it will return a string (without
ANSI escape color codes) representation instead.

This is useful in situations when you need to log the ordinary
gst_debug log to a resource that can't be opened as a `FILE` handle.

Also includes a test.

0cb3940c94 bin: Add method to find elements by factory name
A common use case of a dynamically built pipeline is that you want to
(conditionally) find a certain element, e.g. the `rtpbin`s in a
`uridecodebin`. If that element has a fixed name inside its parent bin
(and only has a single instance) this can be easily done by
`gst_bin_get_by_name()`.

If there are multiple instances of the element however, you can only use
`gst_bin_iterate_all_by_interface()`, but this doesn't work if you don't
have the specific `GType` (which is often the case, due to plugins being
dynamically loaded). As such, another fallback could be to use the
well-known name of the element's factory (in case of our example, this
is of course `"rtpbin"`).

25d7914395 tests: fix pipelines_parse_launch.delayed_link flakiness
Fixes #345

There were two causes for the flakiness, one much rarer than
the other.

The test sets up a source with a sometimes pad added during
the transition of a wrapper bin from READY to PAUSED.

It runs 4 iterations, the last of which makes it so the
negotiation fails.

In that case, the intention as correctly presented by the following
comment:

/* [..] ie, the pipeline should create ok but fail to change state */

However the implementation of run_delayed_test was neither calling
get_state on the pipeline (it called it on the wrapper bin), nor
checking that the return of get_state was FAILURE (it actually
checked that it was not).

This led to an obvious race condition, and was fixed by calling
get_state on the pipeline, then checking that in this specific
case (expect_link == FALSE), the state change has actually failed.

The second, rarer race condition is at set_state time. When we
don't expect the link to succeed, the return of set_state may
either be FAILURE or ASYNC, depending on timing. This was fixed
by taking expect_link into account when checking the return value
of set_state.

7af50da2c9 bus: Use new GSource dispose function
Without this it is possible that we have a GSource with reference count
0 stored in the GstBus that is currently in the process of being
destroyed. gst_bus_remove_watch() might then access it, increase its
reference count to 1 again, call GSource API on it and then unref it,
which will then finalize it a second time.

The dispose function allows the GSource to be resurrected until it
returned so the above would be safe now.

This caused some spurious crashes during shutdown in various
applications.
