Point g-ir-scanner to the .la file of our library, which hopefully
makes it find the right dependencies in all cases (ie. our locally
built libgstreamer and not the system-installed one). This is also
how it's done in Gtk+ and how it's documented in the wiki, see
http://live.gnome.org/GObjectIntrospection/AutotoolsIntegration
Based on patches by Vincent Untz and Alan Knowles.
Fixes#603710.
Our own pkgconfig directory should come first, so that pkg-config uses
the in-tree libgstreamer and not some external one when --pkg=gstreamer-0.10
is passed to g-ir-scanner.
See #603710.
As the headers were broken in 0.10.26 the functions weren't really
usable back then, so we should advertise them as being there only
since 0.10.27.
Spotted by Mart Raudsepp.
When doing pad_allocs, use non-fixed caps suggestions and
try to fixate them before using. This makes possible to
have suggested buffer size with 0 in basetransform just
to signal upstream a renegotiation is needed
Fixes#576234Fixes#609046
Adds that warning to configure.ac
Includes a tiny change of the GST_BOILERPLATE_FULL() macro:
The get_type() function is no longer declared before being defined.
https://bugzilla.gnome.org/show_bug.cgi?id=611692
The functions are called gst_byte_writer_put_{float32|float64}_*() and not
gst_byte_writer_put_{float|double}_*().
Spotted by: Benjamin Otte <otte@redhat.com>
_get_range() is a pad function set by ourselves, therefore we're certain that
the parent is a GstBaseSrc.
Speeds up _get_range by 38%, and the total call by 30%. (valgrind instruction
calls measurements).
Fixes#610246
Adds a new function to GstByteWriter that writes
a constant value to a memory area (aka memset).
Useful for adding padding to buffers.
Also updates .def file and docs.
API: gst_byte_writer_fill()
Updating the segment values must only be done while holding the
STREAM_LOCK and OBJECT_LOCK. This means, reading can be done as
long as one of them is held, not both, which removes some lock-unlock
blocks from performance critical code paths.
Also document, that gst_base_src_set_format() *must* be called in
states <= READY and add an assertion for this. Changing the format
later will completely mess up the segment information.
gst_byte_writer_reset_and_get_buffer wasn't declared
in .h, instead there was _reset_and_get_data_as_buffer.
Replace it with the real function name, that is smaller
and matches gst_byte_writer_free_and_get_buffer
https://bugzilla.gnome.org/show_bug.cgi?id=608726
For the reason outlined at the beginning of gst_private.h (inline
functions in glib may need the g_log_domain variable). Also include
gst_private.h before using any G_OS_* defines, esp. in plugin loader.
Add a method to perform get_range typefinding that also uses the
uri/location extension as an extra hint. It will first try to call the
typefind functions of the factories that handle the given extension. The result
is that in the common case, we only call one typefind function, which speeds up
the typefinding a lot.
Make sure we take ownership of the buffer early without increasing its refcount
when we go in the collect function. This reduces the amount of copies needed in
order to make the buffer writable in most cases.
In some cases we can avoid allocating a subbuffer and instead simply ref
the buffer. Callers should perform _make_metadata_writable() in all
cases now.
Add a method to install a clipping function that is called when a buffer is
received. Users of collectpads can then perform clipping on the incomming
buffers.
Also retab the header file a little.
See #590265
This allows demuxers to update the segment stop of an already
finished stream. This might be needed if some stream goes to
EOS before the duration of the longest stream is known to properly
set the segment stop of all streams to the same value in the end.
Set the pad flushing and stop the pad task when the initial seek fails
during activation. Avoids racy calls into the _create() function when
BaseSrc::stop() has already run.
Fixes: #603059
Also, fix some misspelled comments.
Rounding errors with the floating point rate could make it so that we
don't end up exactly at the required stepping duration.
Use the segment clipping boundaries, which are not subject to rate
adjustements, instead to detect when we reached the stepping duration.
Add some debug info related to going to the PAUSED state.
Some gcc versions warn about bytewriter writing to memory accessed
via a const guint8 pointer, despite our explicit cast to guint8 *.
Work around that by using an intermediary variable.
Fixes#598526.
When clamping the base time, correctly use 'now', instead of
'-now' - the intent is to prevent 'now-base' ever being
negative, which would cause a position report outside the segment.
Fixes: #602419
Element base_time is a signed quantity, which leads to basesink returning
a position of 0 when dealing with a negative base time - which are quite
legal when clocks (such as the audio clock) are close to 0.
This doesn't manifest in normal pipelines, of course - but can happen
(at least) when manually setting the base time on a pipeline.
This avoids:
* triple-checking for the GType when type-checking is enabled (see #597260)
* Avoids going through an expensive no-argument checking which landed in
glib-2.22
* Avoids going through 2 extrac functions (g_object_new -> g_object_new_valist)
There's not much point in using GST_DEBUG_FUNCPTR with GObject
virtual functions such as get_property, set_propery, finalize and
dispose, since they'll never be used by anyone anyway. Saves a
few bytes and possibly a tenth of a polar bear.
This avoids having to do the sorting everytime we use typefind
The behaviour of gst_type_find_factory_get_list has subtlely changed
in the sense that the order was previously undefined, whereas now
it returns them sorted by rank and then by name.
The list against which we run the comparefunc will only contain
GstPluginFeature, therefore remove the 6 expensive type checks we do
for every single comparision.
When we quickly switch from PLAYING to PAUSED and back to PLAYING it's possible
in some cases that the task refuses to start, This is because when we go to
PAUSED, we unschedule the clock timeout, which could return UNSCHEDULED when
we're back to PLAYING, causing the task to PAUSE again with a wrong-state.
This patch checks if we are running when we return with an UNSCHEDULED return
value and if we are, try to create a new buffer.
Fixes#597550
The code was previously:
* checking if ret was != OK
* .. but if it was FLOW_STEP, swith it to OK
* .. and then not using ret
Instead we just make it more compact by checking if it's OK or STEP.
In most places in core and baseclasses we just need the caps to do caps-
intersections. In that case ref'ed caps are enough (no need to copy).
This patch also switches the code to use the new functions.
API: gst_pad_get_caps_refed(), gst_pad_peer_get_caps_refed()
The normal functions are always useful to have for bindings, especially
runtime-created bindings like Seed or new GObject-Introspection based
Python bindings.
Check when we need to touch the metadata of the output buffer after selecting
the output buffer so that we have everything in one place.
Also take flags and timestamp modifications into account.
When we have the same input as output caps, reuse the input caps object. After
the caps refcounting has been sorted out now, we can finally enable this
optimisation.
Without this, we risked:
* Checking the flushing state on an unexisting list
* Not setting the flushing state on pads that had just been added
Partially fixes#590056
Return FALSE in basesrc's default query handler when we get a SEEKING query for
a format that's not the one the source operates in. Previously (ie. before, in
the git version) we would return TRUE in that case and seekable=FALSE, which
is more correct, but causes backwards compatibility problems. (Before that
we would change the format of the query when answering, which was completely
broken since callers don't expect that or check for it). Since the SEEKING
query is a fairly recent addition, not all demuxers, parsers and decoders
implement it yet, in which case any SEEKING query by an application will
just be passed upstream where it will then be handled by basesrc. Now, if
e.g. totem does a SEEKING query for TIME format and we have a demuxer that
doesn't implement the query, basesrc would answer it with seekable=FALSE in
most cases, and totem can only take that as authoritative answer, not knowing
that the demuxer doesn't implement the SEEKING query. To avoid this, we make
basesrc return FALSE to SEEKING queries in unhandled formats. That way
applications like totem can fall back on assuming seekability depending on
whether a duration is available, or somesuch. Downstream elements doing
such queries are likely to equate an unhandled query with a non-seekable
response as well, so this should be an acceptable fix for the time being.
See #584838, #588944, #589423 and #589424.
Clarify byte reader docs a bit: offset is relative to the current
position of the reader, not to the start of the data. Also, the
examples in both the adapter docs and the byte reader docs have
the mask and pattern arguments swapped (see #587561). Spotted
by Carl-Anton Ingmarsson.
Add a pattern scan function similar to the one recently added to
GstAdapter, and a unit test (based on the adapter one).
Fixes#585592.
API: add gst_byte_reader_masked_scan_uint32()
Update design doc with step-start docs.
Add eos field to step done message
when stepping in reverse, update the segment time field.
Flush out the current step when we are flushing.
When we start stepping, store the start/stop values of the segment before we
install new start/stop values for clipping in non-flushing steps.
for non-flushing steps, update the element start time. For flushing steps, it
does not change because running_time does not advance
Make sure we always perform the stop_stepping operations even when we drop
frames.
Note in the docs that a flushing step in PLAYING brings the pipeline to the lost
state and skips the data before prerolling again.
Implement the flushing step correctly by invalidating the current step
operation, which would activate the new step operation.
When a subclass is blocking in _wait_preroll() in the _render method, make sure
we can unlock the subclass and detect this return value from the render method.
Update framestep document, we want to pass the flush flag in the step-done
message.
Add flush flag to the gstmessage.
Update examples to use the new step-done message api.
Implement framestep with playback rates < 0.0 too.
Make start and stop_stepping methods and move their invocation in the right
places.
Perform the atual stepping operation where we have full context about the
timestamps.
Unlock the prerolled frame and recheck if we need to step.
Keep a simple counter for the frames we're about to skip while stepping and
preroll/post step_done when stepping finished.
gst_adapter_masked_scan_uint32 could return values smaller than offset
if the first byte(s) of the mask are 0 and the pattern matches the
beginning of the adapter.
Added examples to documentation of gst_adapter_masked_scan_uint32().
Also added some more masked boundary tests.
Fixes#584118
Add a reasonably optimized new gst_adapter_masked_scan_uint32() function
to scan the adapter for a pattern after applying a mask.
Add some unit tests.
API: GstAdapter::gst_adapter_masked_scan_uint32()
Fixes#583187
Don't use realloc to grow the scratch area because we don't want the memcpy the
old useless data into the new area before we write our new stuff in it.
When a are requested to take a buffer from the adapter that is exactly the
headbuffer, don't make a subbuffer of it but return that head buffer.
Add a unit-test for this new optimisation.
Due to a typo basesink didn't do any emergency rendering of late buffers
if the only buffer ever rendered was the first one with timestamp 0. This
means that in cases where the decoder is very very slow, we'd never see
any buffers but the very first one rendered. Fixes#576381.
When we are not ready to handle a latency query (we are not yet prerolled) we
also don't try to forward the latency event because that might cause unexpected
errors when upstream is not yet linked.
Fix a regression introduced by fix for #567725 in commit
1c7ab4ed4f. We should only call the preroll
function once namely when we did not yet commit the state change.
Add a unit test to check that we call the preroll function when interrupting the
clock_wait (see #567725).
Add a unit test to check that we only call the preroll function once.
While reconfiguring a basetransform element we need also to recheck
the alloc request. Because it's possible that due to caps changes
the proxy_alloc state is not correct anymore.

(gst_base_transform_prepare_output_buffer):
Add debug info.
When a buffer is writable, its metadata is also writable so we don't
need to subbuffer (which then makes the buffer not-writable anymore).
Original commit message from CVS:
* libs/gst/base/gstbasesink.c: (gst_base_sink_set_async_enabled),
(gst_base_sink_set_ts_offset), (gst_base_sink_perform_qos):
Add some debug.
Make sure we don't generate invalid QoS messages.
Original commit message from CVS:
* libs/gst/base/gstbasesink.c: (gst_base_sink_get_sync_times),
(gst_base_sink_get_position):
The reported position must always be smaller than the last seen
timestamps (or timestamp + duration for reverse).
Original commit message from CVS:
* libs/gst/base/gstbasesink.c: (gst_base_sink_get_sync_times),
(gst_base_sink_get_position_last), (gst_base_sink_get_position):
Fix position query range checks in reverse playback.

Make sending an EOS event to the basesrc non-blocking even if the
implementation does blocking waits in the create function. This is done
by unlocking the create function when EOS is sent.
Fixes#535218.

* libs/gst/base/gstbasesink.c: (gst_base_sink_get_sync_times):
If nothing else can be used, use the last buffer's start time as
the segment's last stop. Fixes bug #534258.

* libs/gst/base/gstbasetransform.c:
(gst_base_transform_sink_event):
Unref events that the GstBaseTransform::event vfunc didn't want to
have forwarded by the base class. Closes a leak in identity.
Fixes bug #446763.
Original commit message from CVS:

* libs/gst/base/gstbasesink.c: (gst_base_sink_wait_clock):
* libs/gst/base/gstbasesink.h:
Expose a method that was previously used internally to synchronize
against the clock because it can be useful for subclasses too.
GstBaseSink::gst_base_sink_wait_clock()
Original commit message from CVS:

(gst_base_sink_wait_clock), (gst_base_sink_wait_eos),
(gst_base_sink_do_sync), (gst_base_sink_chain_unlocked):
Refactor adjusting the running_time with latency and offset into a
separate method.
When doing clipping, we still want to use the subclass get_times method,
just in case the DURATION or TIMESTAMP are not set.
Original commit message from CVS:
* libs/gst/base/gstbasesrc.c: (gst_base_src_start):
Use right error code when typefinding fails, so we can use
the default (translated) error messages.
Original commit message from CVS:
* libs/gst/base/gstbasesrc.c: (gst_base_src_get_range),
(gst_base_src_start):
When the subclass did not set caps on outgoing buffers, configure the
caps we negotiated on the source pad.
When the typefind helper does not find caps, error out properly instead
of doing things with NULL caps.
Original commit message from CVS:
* libs/gst/base/gsttypefindhelper.c: (helper_find_peek):
Sort buffer cache list by end offsets. This makes sure that we don't
stop to search for a cached buffer that contains the requested data
too early.
Also read a minimum of 4k bytes instead of 512 bytes as this is a bit
more efficient. Fixes bug #459862.

* libs/gst/base/gstbasetransform.c:
(gst_base_transform_buffer_alloc):
Check the caps of the buffer returned by gst_pad_alloc_buffer() and
fall back to default negotiation in the chain function if the caps
are different from what was requested. Fixes bug #526768.
Original commit message from CVS:
Based on a patch by: Sjoerd Simons <sjoerd at luon dot net>
* libs/gst/base/gstbasetransform.c:
(gst_base_transform_buffer_alloc):
Don't passthrough buffer allocation too easily if the caps change.
This breaks when working in passthrough mode and upstream changes
it's caps. Fixes bug #526768.
Original commit message from CVS:
* libs/gst/base/gstbasesink.c: (gst_base_sink_query_latency),
(gst_base_sink_send_event):
Rearrange the latency query code. We always want to do the upstream
query, even if we are not live so that the upstream elements can get the
latency results too. If we fail doing the query and we are live, we
return TRUE afterwards.

Make _wait_playing() not check any variables so that we can call this
function from subclasses. Move the checks elsewhere similar to
_wait_preroll() in basesink.
Add some debugging.
Only signal the LIVE cond when we are going back to PLAYING.

Thanks Tim for spotting.
Original commit message from CVS:
* libs/gst/base/gstbasesink.c: (gst_base_sink_set_last_buffer):
Don't hold the object lock when unreffing a buffer because it could

Don't try to report a 0 position when we don't know, return -1 and FALSE
instead. This mostly happens when we are prerolling.
Make sure we can report the right position before we post the ASYNC_DONE
message so that a message handler can query position without races.
