This simplifies navigating in a GStreamer pipeline, e.g.
(gdb) print $gst_bin_get($gst_pipeline(pad), "matroskademux0")
$1 = 0x7fffe81b4050 [GstMatroskaDemux|matroskademux0]
For elements, this adds all child elements, the state and base/start time:
(gdb) gst-print pipeline
0x5555556ebd20 "pipeline0"
GstPipeline(pipeline0) {
children:
fakesink0
queue0
videotestsrc0
state: PLAYING
base_time: +2:54:36.892581150
start_time: 0:00:00.000000000
}
For pads, this adds the peer pads and the current task state and the
offset (if not zero):
(gdb) gst-print pad
SrcGhostPad(src, push) {
events:
[...]
peer: vaapisink0:sink
inner peer: scale:src
}
(gdb) gst-print pad
SrcPad(src, push) {
events:
[...]
peer: queue0:sink
task: STARTED
offset: 30000000 [+0:00:00.030000000]
}
* Making sure that `static inline` function are in the GIR (by first
defining them, and make sure to mark as skiped)
* Do not try to link to unexisting symbols
* Also generate GIR information about gst_tracers
The original version of the patch used glib-2.0 but that was later changed
to gstreamer-1.0 for autotools. The meson file was forgotten.
Fix the path to match the one used in libgstreamer-gdb.py.in.
It's possible that setcap is installed, but the libcap headers/libs aren't (e.g.
during cross compilation, when you have the program installed for the host,
but need the headers of the target). Also removes the need to manually check
for the libcap headers.
Internal gst_net_utils_set_socket_dscp renamed and turned into external
function. Similar functionality exists in e.g. multidupsink, which could
instead use this one.
The signal will be emitted when a buffer was consumed on
a pad, if the newly-added "emit-signals" property has been
set to TRUE.
Handlers connected to the signal will receive a valid reference on
the consumed buffer, allowing for example the retrieval of metas in
order to forward them once an output buffer is pushed out.

This adds two custom gdb commands:
'gst-dot' creates dot files that a very close to what
GST_DEBUG_BIN_TO_DOT_FILE() produces. Object properties and buffer content
(e.g. codec-data in caps) are not available.
'gst-print' produces high-level information about GStreamer objects. This
is currently limited to pads for GstElements and events for the pads. The
output can look like this:
(gdb) gst-print pad.object.parent
GstMatroskaDemux (matroskademux0) {

Fixes flaky appsrc unit test where depending on scheduling
the submitted list might not be writable if submitted via
an action signal from the application thread.
Fixes gst-plugins-base#522
baseparse internally uses a 64kb buffer for pulling data from upstream.
If a 64kb pull is failing with a short read, it would previously pull
again the requested size.
Doing so is not only inefficient but also seems to cause problems with
some elements (rawvideoparse) where the second pull would fail with EOS.
Short reads are only allowed in GStreamer at EOS.
Closes https://gitlab.freedesktop.org/gstreamer/gstreamer/issues/294
Without this bindings get confused about the meaning of references, and
we really own these references if they are not already owned by
something else.
We won't be able to do ASSERT_CRITICAL, but the main body of the tests
are still valid, and given we ship GStreamer with this configuration, it
is important to be able to run some tests against it.
This adds gdb pretty printer for some GStreamer types.
For GstObject pointers the type and name is added, e.g.
"0x5555557e4110 [GstDecodeBin|decodebin0]".
For GstMiniObject pointers the object type is added, e.g.
"0x7fffe001fc50 [GstBuffer]".
For GstClockTime and GstClockTimeDiff the time is also printed in human
readable form, e.g. "150116219955 [+0:02:30.116219955]".
Fixes#320
By moving the functionality down to the testclock, the implementation
no longer needs to poll the waits, but rather wait properly for
them to be added.
The performance-hit here would be that by polling the test-clock
regularly, you would create contention on the testclock-lock, making code
using the testclock (gst_clock_id_wait) fighting for the lock.
