21798184a0 aggregator: Assert if the sink/src pad type that is to be used is not a GstAggregatorPad or subclass thereof 2019-08-13 17:11:51 +00:00

b8455445c5 aggregator: Ensure that the source pad is created as a GstAggregatorPad if no type is given in the pad template
Otherwise we would create a GstPad and that causes invalid memory
accesses later.

9ec55072d2 aggregator: drop duplicated SEEK events
This is similar to what demuxers do, and necessary when multiple
sinks get seeked downstream of the aggregator: if we forward
duplicated seeks upstream, elements such as demuxers may drop
the flushing seeks, but return TRUE, aggregator then waits forever
for the flushing events.

Fixes #276

09909d37bd aggregator: Make parsing of explicit sink pad names more robust
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 '%'.

strcmp() does not allow the arguments to be NULL, but g_strcmp0()
does, so document that we use g_strcmp0() so that people don't need to

91543bd78d testclock: Allow calling crank with a past entry
At the moment, we can only use crank if the pending entry is in the
future. This patch leaves the clock time to the same point if the
pending entry was in the past. This still execute a single entry. This
will be needed for the jitterbuffer, since as soon as we stop waking up
the jitterbuffer when the timer is reschedule later, we may endup with
such case in the unit tests.

229b4776ea harness: move creating of buffer and event queues to harness itself
By only having it on sinkpad-creation, it is racy to write a test
with a sometimes-pad (like a demuxer) that you want to pull from, having
the pull wait until the pad arrives and the buffer can be produced.

69430dd7ba harness: Make sure pad functions are not called after teardown
For the query function there's a risk that the function may be called
after the harness has been teared down. Since the function accesses a
pointer to the harness via the pad's data, the harness must protect
itself against this.

Event and chain function is also handled for constistency, although
they don't have the same problem since the gstpad.c checks whether the
pad is flushing before calling these.

6d16615093 aggregator: don't try to take STREAM_LOCK on sink pad flush
This was a misguided effort to try and guarantee the buffers of
the sink pads would not change during aggregate, when an upstream
branch is seeked independently, however this is simply incorrect
as downstream has not necessarily been flushed, or the aggregate
function might be waiting to receive buffers on other pads.

4087361da3 aggregator: send flush_stop ourselves if needed
In !159 , we switched to sending flush_start ourselves from the
do_seek implementation. If no flushing seek successfully made its
way upstream, we need to send flush_stop ourselves as well.

c55c61eb84 aggregator: don't hold stream lock when flushing
Releasing a GRecMutex from a different thread is undefined
behaviour.

There should be no reason to hold the stream lock from the
moment aggregator receives a flush_start until it receives
the last flush_stop: the source pad task is stopped, and can
only be restarted once the last flush_stop has arrived.

I can only speculate as to the reason why this was done,
as it was that way since the original commit. My best
guess is that aggregator originally didn't marshall events
and queries to the aggregate thread, and this somehow
helped work around this.

25383eaa5c aggregator: refactor flushing logic
Instead of tracking "pending_flush_*" on the pads and the
aggregator, we now simply track the last seqnum for flush start
and flush stop events on the pads, and use it to determine whether
we should enter or exit our flushing state.

09141c6e1f Use G_DEFINE_AUTOPTR_CLEANUP_FUNC unconditionally
Since we started depending on GLib 2.44, we can be sure this macro is
defined (it will be a no-op on compilers that don't support it). For
plugins we should just start using `G_DECLARE_FINAL_TYPE` which means
we no longer need the macro there, but for most types in core we don't
want to break ABI, which means it's better to just keep it like it is
(and use the `#ifdef` instead).

1a3bf3234f aggregator: fix flow-return boolean return type mismatch
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.

36c2fc3bc3 gdb: gst-print add more pad and element information
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

c5b85da8ef gdb: implement 'gst-dot' and 'gst-print' commands

'gst-dot' creates dot files that a very close to what

'gst-print' produces high-level information about GStreamer objects. This

bf1979e55f baseparse: Use buffer from short reads instead of pulling again
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.

readable form, e.g. "150116219955 [+0:02:30.116219955]".

fa34768729 harness: improve _wait_for_clock_id_waits performance
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.

04176bede1 ptp clock: Wait for ANNOUNCE before selecting a master
Previously, with opportunistic sync we'd track a master
clock as soon as we see a SYNC message, and hence sync up
faster, but then we'd announce we're synched before seeing
the ANNOUNCE, leaving the clock details like grandmaster-clock
empty.

A better way is to start tracking the clock opportunistically,
but not announce we're synched until we've also seen the ANNOUNCE.

6a653437ac ptp clock: Increase tolerance for late follow-up and delay-resp
The follow-up and delay-resp messages carry precise
timestamps for the arrival at the clock master, but
the local return time is unimportant, so we should be very
lenient in accepting them late. Some PTP masters don't
prioritise sending those packets, and we reject all the
responses and never sync - or take forever to do so.

Increase the tolerance to 20x the mean path delay.

Also fix a typo in one debug output that would print
the absolute time of the delay-resp message, not the offset
from the delay-req that it's actually being compared against.

50c32da91f meson: use library() for libgstcheck instead of always building a shared lib
Otherwise we try to build a shared lib when we build the rest
of GStreamer statically, which won't work because we pass
-DGST_STATIC_COMPILATION when building statically, which means
we won't dllimport public symbols from our libs which means
that on Windows the unit tests will fail to link to libgstcheck.

57c8e0146f libs: figure out right export define in configure
Add new GST_API_EXPORT in config.h and use that for GST_*_API
decorators instead of GST_EXPORT.

The right export define depends on the toolchain and whether
we're using -fvisibility=hidden or not, so it's better to set it
to the right thing directly than hard-coding a compiler whitelist
in the public header.

We put the export define into config.h instead of passing it via the
command line to the compiler because it might contain spaces and brackets
and in the autotools scenario we'd have to pass that through multiple
layers of plumbing and Makefile/shell escaping and we're just not going
to be *that* lucky.

The export define is only used if we're compiling our lib, not by external
users of the lib headers, so it's not a problem to put it into config.h

Also, this means all .c files of libs need to include config.h
to get the export marker defined, so fix up a few that didn't
include config.h.

This commit depends on a common submodule commit that makes gst-glib-gen.mak
add an #include "config.h" to generated enum/marshal .c files for the
autotools build.

46ed0f0489 libs: fix 'inconsistent DLL linkage' warnings on Windows
For each lib we build export its own API in headers when we're
building it, otherwise import the API from the headers.

This fixes linker warnings on Windows when building with MSVC.

The problem was that we had defined all GST_*_API decorators
unconditionally to GST_EXPORT. This was intentional and only
supposed to be temporary, but caused linker warnings because
we tell the linker that we want to export all symbols even
those from externall DLLs, and when the linker notices that
they were in external DLLS and not present locally it warns.

What we need to do when building each library is: export
the library's own symbols and import all other symbols. To
this end we define e.g. BUILDING_GST_FOO and then we define
the GST_FOO_API decorator either to export or to import
symbols depending on whether BUILDING_GST_FOO is set or not.
That way external users of each library API automatically
get the import.
