Especially drop tag events when flushing to not send them over
and over again.
Should've been in the last commit already but I forgot to call
git rebase --continue...
basesrc's default event handler returns TRUE regardless of whether the
event is handled or not. This fixes the handler to conform with the
expected behaviour (which is to only return TRUE when the event has
actually benn handled). gst_bin_do_latency_func() depended on this
(incorrect) behaviour, and is now modified as well.
(Remaining 1-liner change in gstbasesrc.c is to keep gst-indent happy)
Deal with the hints from gtk-doc and fix the xrefs. Apply a work-around for ()
precedence over @. Move "MT Safe" text to doc body in many places. Trim eol
whitespaces.
If the element gave us caps in a specific order, let's retain that
by intersecting against the template but retaining the order given
by the element.

Avoid doing unnecessary pad-allocs when on passthrough mode.
If multiple basetransform elements are on a pipeline, they
would do a pad-alloc for each received buffer, each element
would do this, so we would have lots of pad allocs on the
pipeline for a single buffer being pushed through it.
This patch attempts to reduce this amount by avoiding
doing pad-allocs if the element has already done it
after the last pushed buffer. So it will only be allowed
to do a new pad-alloc after it has pushed a buffer, so we get
1x1 pad-alloc and buffer ratio
https://bugzilla.gnome.org/show_bug.cgi?id=642373
If after computing the suggestion with downstream caps we still have
a non-fixed suggestion caps try to intersect with the input caps
of the pad alloc to avoid useless renegotiations.

Improve the calculation of the duration. When we have no input duration set on
the input buffers stop is set to start and then we end up using a 0 duration in
the average calculation.
Keep track of the earliest allowed timestamp according to the latest
QoS report and drop buffers before that time. Activate this filter
when throttling is enabled. We could later also activate this in the
other QoS cases.
See #638891
Apply fix from libgstbase to all core libs now that we know that it
works. Should fix problems with g-ir-scanner using the wrong
(ie. system) libgstreamer, leading to linking errors such as
undefined reference to `gst_clock_single_shot_id_reinit'.

Previously it was - probably due to copy/paste error - looking for
gstbase headers.
It's changed now to only include the one public header for gstnet.h
Only go into LIVE_WAIT when the are not live_running and only stop waiting when
live_running is TRUE. If we don't loop, we could deadlock when called from
outside of basesrc, such as baseaudiosrc.
Fixes#635785
This can happen for example when downstream proposed new caps, later proposed
the previous caps again which in turn enables passthrough mode in upstream
elements and the wrong-sized buffer appears in an element where the caps
change never happened. Simply allocate a new buffer in this case.
See bug #635461.
Only update the last_stop value when we had a valid stop position for the
clipping or else the clipping code assumes the stop position extends to the end
of the segment, which makes the position reporting return weird values.
Make the _get_caps functions behave like the _get_caps_reffed variants and
remove the _reffed variants. This means that _get_caps doesn't return a writable
caps anymore and an explicit _make_writable() is needed before modifying the
caps.
Because of the new pad caching system, the peer pad might still
have a reference on a pad. We therefore delay the refcount checking
til 'after' we unlink the pad from any potential peer.
Unify the different position reporting code paths to make it more
understandable.
Use start_time to get more accurate position reporting in paused.
Fix unit tests for more accurate reporting.
This reverts commit 80727c1177.
This doesn't make sense. gst_data_queue_new_full() is already
documented above. And we need the doc blurb for _new() here.
So run-time bindings can introspect the names correctly (we abuse this
field as description field only in elements, not for public API
(where the description belongs into the gtk-doc chunk).

Use atomic ops to read and write more properties. Taking the preroll lock in get_property
can lock up applications reading the property during preroll.
Because of the awkward refcounting in prepare_output_buffer, we might end up
with writable buffers that point to the same data. Check for those cases so that
we avoid a useless memcpy and keep valgrind quiet.
Fixes#628176
Add a function to retrieve a list of buffers containing the first N bytes from
the adapter. This can be done without a memcpy and should make it possible to
transfer the list to a GstBufferList later.
Make code including GStreamer headers compile with -Wcast-qual by
maintaining const-ness when casting. Also fix function signature of
gst_byte_writer_set_pos(): the byte writer should not be marked as
const.

Sets up a GST_PKG_CONFIG_PATH variable for use in Makefile.am
(avoids trailing ':' in PKG_CONFIG_PATH used). A useful side
effect of this is also that the PKG_CONFIG_PATH environment
is now logged in the configure output.
When we are handling a buffer and need to allocate an output buffer, handle the
case when downstream suggests us a format that we can't convert the input buffer
to. In that case, check if there is another format available downstream instead
of failing.
Fixes#621332 and see also #614296
If initially pass-through caps are negotiated between a transform element's
sink and src pads, but then the downstream element returns different caps
on a buffer from pad_alloc(), basetransform gets stuck with proxy_alloc=TRUE
even though the upstream peer doesn't accept the caps, causing
gst_pad_peer_accept_caps() to be called on each buffer in _buffer_alloc():
if (!gst_caps_is_equal (newcaps, caps)) {
GST_DEBUG_OBJECT (trans, "caps are new");
/* we have new caps, see if we can proxy downstream */
>> if (gst_pad_peer_accept_caps (pad, newcaps)) {
/* peer accepts the caps, return a buffer in this format */
GST_DEBUG_OBJECT (trans, "peer accepted new caps");
which is taking ~40ms/frame.
This patch does two things. (1) if the buffer returned from pad_alloc() has
new caps, trigger the decision whether to proxy the buffer-alloc to be
revisited, and (2) disable proxy if peer does not accept new caps. (The first
part may not be strictly needed, but seemed like a good idea.)
Note that this issue would not arise except in case of downstream elements
who have on their template-caps, some that would be suitable for pass-through,
but at runtime pick more restrictive caps (for ex, after querying a driver for
what formats it actually supports).
When basetransform received an unsupported caps on pad_alloc
it just returned not-negotiated. This patch makes it query
the allowed caps between his sinkpad and upstream's srcpad
to find a caps to suggest.
This happens when dinamically switching pipeline elements
and upstream pad_allocs with the previous caps that was
being used.
Fixes#614296
Add a new enable-last-buffer property. When false, it disables storing the last
received buffer in basesink::last-buffer. This can be useful in cases where
buffers need to be released asap.
API: GstBaseSink::enable-last-buffer
Retain the last scanned buffer entry and offset, so we can resume buffer
scanning there in case of a typical progressive scan.
Also potentially optimize _copy subsequently occurring in that area.
Allow subclasses to override the acceptcaps function because in some cases a
custom implementation can be much much faster than the default one.
See #621190
The logic in that function is broken. Various NULL-checking bandaids for
guaranteed non-NULL variables didn't even help there.
This patch updates the function to check if a previous item exists
before fetching it instead of after. This makes all other tests
unnecessary.
In particular, it makes the check for an empty list unnecessary, because
for empty lists the only iter is the begin iter (and the end iter) and
so the new check catches that case.

Use foo_LDADD instead of foo_LDFLAGS to specify the libraries to link to.
This should make sure arguments are passed to the linker in the right
order. See #615697.
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
This changes some APIs in compatible ways:
- Some functions now take "const char *" arguments, not "char *"
- Some structs now have "conts char *" members, not "char *"
The changes may cause warnings when compiling with the right warning
flags. You've been warned.
Also adds -Wwrite-strings as a warning flag in configure.ac.
https://bugzilla.gnome.org/show_bug.cgi?id=611692
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
This makes it >10x faster if more than a single value is requested
by not searching in the GSequence for every value and converting
the value from GValue to the real value type.
The functions are called gst_byte_writer_put_{float32|float64}_*() and not
gst_byte_writer_put_{float|double}_*().

_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.
