This add the different timestamps for segment events:
(gdb) gst-print pad
SrcPad(src, push) {
events:
[...]
segment: time
rate: 1.1
start: 0:03:08.449753330
time: 0:03:08.449753330
position: 0:03:08.449753330
duration: 0:12:14.166687500
[...]
}
It shows a simple tree of all elements in pipeline.
As with gst-dot, the toplevel bin is found from any element of the
pipeline:
(gdb) gst-pipeline-tree bsink
playbin
inputselector1
inputselector0
uridecodebin0
queue2-0
decodebin0
avdec_aac0
aacparse0
vaapidecodebin0
vaapipostproc0
capsfilter1
vaapi-queue
vaapidecode0
capsfilter0
h264parse0
multiqueue0
matroskademux0
typefind
typefindelement0
source
playsink
abin
aconv
resample
conv
identity
aqueue
pulsesink0
vbin
vconv
scale
conv
identity
vqueue
vaapisink0
vdbin
deinterlace
vdconv
audiotee
streamsynchronizer0
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]
}
This URI is valid:
data:,;base64
(It encodes the literal string ";base64")
But would lead to a crash because the code assumed the semicolon would
be placed before the colon.
Quoting RFC 2396:
For resiliency, programs interpreting URI should treat upper case
letters as equivalent to lower case in scheme names (e.g., allow
"HTTP" as well as "http").
Before GST_PAD_PROBE_HANDLED was introduced, we had to handle the case
where some probes would reset the probe info data field to NULL. This would
be considered an invalid use-case.
But with GST_PAD_PROBE_HANDLED it is totally fine to reset that, since
the probe has "handled" it.
This seems to happen when another client is accessing the file at the
same time, and retrying after a short amount of time solves it.
Sometimes partial data is written at that point already but we have no
idea how much it is, or if what was written is correct (it sometimes
isn't) so we always first seek back to the current position and repeat
the whole failed write.
It happens at least on Linux and macOS on SMB/CIFS and NFS file systems.
Between write attempts that failed with EACCES we wait 10ms, and after
enough consecutive tries that failed with EACCES we simply time out.
In theory a valid EACCES for files to which we simply have no access
should've happened already during the call to open(), except for NFS
(see open(2)).
This can be enabled with the new max-transient-error-timeout property, and
a new o-sync boolean property was added to open the file in O_SYNC mode
as without that it's not guaranteed that we get EACCES for the actual
writev() call that failed but might only get it at a later time.

When inspecting plugins to generate the json cache file. Otherwise
when we are not in the uninstalled env and using `gst-build` plugins
with dependency might fail/throw warning, etc..
* 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
Instead of the object value, this should be used every time a random
value will be returned by g_object_get This is also useful to make the
values returned by inspecting element stable accross runs.
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.
Latency is easier to read when formatted as time rather than displayed
as a flat number in ns.
Especially when displaying GST_CLOCK_TIME_NONE which is now formated as
99:99:99.999999999 instead of 18446744073709551615.
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.
