In gst_download_buffer_wait_for_data(), when a seek is made with
perform_seek_to_offset() the `qlock` is released temporarily. Therefore,
the flushing condition can be set during this period and should be
checked.
This was not being checked before, causing occasional deadlocks when
GST_DOWNLOAD_BUFFER_WAIT_ADD_CHECK() was called.
GST_DOWNLOAD_BUFFER_WAIT_ADD_CHECK() assumes that the caller has already
checked that we're not flushing before, since this is done when
acquiring the lock; so if we release it temporarily somewhere, we need
to check for flush again.
Without that check, the function would keep waiting for the condition
variable to be notified before checking for flushing condition again,
and that may very well never happen. This was reproduced when during pad
deactivation when running WebKit in gdb.
This was added in 1.16 and accidentally duplicated the value of
the existing GST_MESSAGE_REDIRECT.
As the only known user of this message is GStreamer core itself,
and it is quite an obscure message, it seems best to just fix up
the enum value even if that technically breaks API.
Fixes#418
gst_ring_buffer_logger_log calls several functions while formatting
the message which may in turn log a message while we already hold
the mutex. Do all formatting first before acquiring the mutex to
avoid this and reduce the time we hold the mutex.
sync=TRUE implementation changes the latency query of a non-live
upstream into live, though it wrongly set the upstream max latency to 0.
As non-live sources won't loose data if we wait longer, this should have
been reported as have no max latency limite (-1).
When passing "sink_%d" twice to aggregator before it would create two
pads called "sink_0", because it failed to parse "%d" as integer and
used 0 instead then.
Instead validate that parsing was actually successful and also don't
even try to parse if the requested pad name contains a '%'.
The offset in gst_buffer_resize() is additive. So to move back the
offset to zero, we need to pass the opposite of the current offset. This
was raised through the related unit test failingon 32bit as on 64bit
the alignment padding was enough to hide the issue. The test was
modified to also fail on 64bit. This patch will remove spurious
assertions like:
assertion 'bufmax >= bufoffs + offset + size' failed
Fixes#316
The `query` argument of gst_pad_query is "transfer none".
Query objects are "borrowed" by the pad query handlers and those
should never unref them.
This was leading to double freed queries in a very racy way with nested
GESTimelines.
Otherwise when seeking backwards we would keep the last_stop at the last
position we saw until playback passed the seek position again, and if
switching to the next pad happens in the meantime we would set the wrong
offset in the outgoing segment.
Not that it matters, since we don't check the return value
anyway. Unclear why the aggregator pad flush function should
have a return value at all really, and perhaps it should be
called reset anyway. Spotted by dv on irc.
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.
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.
And add strduped function pointer names to the global quark
table, so that they don't get reported as lost by valgrind.
This allows us to use GST_DEBUG when running tests under
valgrind.
Creating seek events segfaults on 32-bit ARM since commit 2fa15d5371
('event: add new seek parameter, "trickmode-interval"'), which missed
casting the trickmode-interval initializer in the variable argument list
to guint64.
The pad name sotred in the latency event has no longer the name of the element,
so we have to get the element Id, element name and pad name values from the data
structure and compare all 3 values.
Otherwise we'll get an assertion if the object behind the weak pointer
was already destroyed in the meantime as we would pass NULL as first
argument to g_object_remove_weak_pointer().
This will output latency information when parsing a log file with gst-stats that
has latency trace information. It will show the min, max and mean latency for
the pipeline and all its elements. It will also show the reported latency for
each element of the pipeline. Output example:
