30c6efc432 gl/mem: allocate the memory per plane
This patch provides the basic infrastructure required for this.
Upload and Download has been ported to this.

Has the nice effect of allowing GstGLMemory to be our
refcounted texture object for any texture type (not just RGBA).

Should not lose any features/video formats.

4ecffcf76b glimagesink: Create GL context and set up window from the streaming thread
gst_gl_context_create() might need to dispatch some operations to the

c2471aec81 gl: add EGLImage support
* picked from old libgstegl:
  - GstEGLImageMemory
  - GstEGLImageAllocator
  - last_buffer management from removed GstEGLImageBufferPool

* add-ons:
  - GstEGLImageMemory now old a reference on GstGLContext
    so that it can delete the EGLImage and its gltexture source
    while having the associated gl context being current.
  - add EGLImage support for GstVideoGLTextureUploadMeta which
    mainly call EGLImageTargetTexture2D
  - GstGLBufferPool now supports GstEGLImageAllocator
  - glimagesink / glfilters / etc.. now propose GstEGLImageAllocator
    to upstream

feacb875a4 alsamidisrc: Improve buffer timestamping
Make buffer timestamps more accurate and, more importantly, actually
representative of the MIDI events timing.

Previously, buffers were only sent with timetamps aligned at a 10ms
boundary which was just wrong, now the buffer timestamp represents the
real time of the MIDI event.

Conveniently, the ALSA sequencer API supports scheduling events in the
future so the sequencer infrastructure can be used to have the tick
delivered at the right time, avoiding any custom scheduling mechanism.

The ticks scheduling starts on the first transition to PLAYING, and the
delay is also calculated when the pipeline goes into PLAYING.

895d884701 oggdemux: Solidify gst_ogg_demux_loop_push() some more
There were still some races going on where seeking events wouldn't
be properly intercepted/executed by this thread.

* Instead of always waiting for the GCond to be emitted, first just
  check if there is an event available
* Take ownership of the event *while* the lock is taken and not
  after releasing/reacquiring it
* Finally acquire lock at the very top and release it at the end
  to make it a bit more streamlined

This removes the remaining issues with seeks not being executed

c86df789ed oggdemux: Drop data before new segment
When calculating duration in push-mode we seek to a certain position
and discard any data until we get data from that requested position.

The problem is that basing ourselves solely on offset to determine
whether we reached the target offset is wrong since the source might
be fast enough  to send us that target position *before* it processed
the requested seek.

This would end up in a situation where:
* We think we're done with duration estimate
* We fire a seek back to "0" in the loop thread
* We resume normal processing
* ... except that we're still getting data from too far ahead which
  we decide to process.
* And we start doing totally wrong granule/time/duration calculation
  and pushing wrong data.

Instead of this confusion, wait until we receive data from the requested
seek. We do that by using the fact that the seqnum in
seek_event_drop_til will be non-zero until the SEGMENT corresponding
to the requested SEEK has been received.

Bonus: makes startup slightly faster

3573238683 gl: do not include GL headers in public gstgl headers
Except for gst/gl/gstglfuncs.h

It is up to the client app to include these headers.
It is coherent with the fact that gstreamer-gl.pc does not
require any egl.pc/gles.pc. I.e. it is the responsability
of the app to search these headers within its build setup.

For example gstreamer-vaapi includes explicitly EGL/egl.h
and search for it in its configure.ac.

For example with this patch, if an app includes the headers
  gst/gl/egl/gstglcontext_egl.h
  gst/gl/egl/gstgldisplay_egl.h
  gst/gl/egl/gstglmemoryegl.h
it will *no longer* automatically include EGL/egl.h and GLES2/gl2.h.
Which is good because the app might want to use the gstgl api only
without the need to bother about gl headers.

Also added a test: cd tests/check && make libs/gstglheaders.check

In gst_ogg_demux_do_seek() when calculating the

Handle a discontinuous first packet in
gst_ogg_demux_setup_first_granule() because that's pretty
normal after a seek. Also differentiate between a genuinely
truncated first packet and just bailing out early, by not using
granule = -1 as an error code.

e575be6dc6 vorbisdec: Reset decoder in more situations
This is a followup commit to b95725c37e

* Resetting the decoder should only happen when we get a new initialization
header (0x01) and not on the other headers
* The initialized variable only gets set to TRUE once all headers have
been parsed. Also check if the vorbis_info struct has been properly resetted
also. Failure to do that would cause vorbisdec to error if it got
two initialization header in a row (the first would configure the underlying
library and the second one would error out because it's already initialized)

With contributions from:

Tim-Philipp Müller <tim@centricular.com>
Jussi Pakkanen <jpakkane@gmail.com> (original port)

Highlights of the features provided are:
* Faster builds on Linux (~40-50% faster)
* The ability to build with MSVC on Windows
* Generate Visual Studio project files
* Generate XCode project files
* Much faster builds on Windows (on-par with Linux)
* Seriously fast configure and building on embedded

... and many more. For more details see:

http://blog.nirbheek.in/2016/07/building-and-developing-gstreamer-using.html

Building with Meson should work on both Linux and Windows, but may
need a few more tweaks on other operating systems.

273d35ce20 oggdemux: remove eos avoidance workaround
This workaround tried to avoid an EOS event when seeking to the
end of an Ogg stream in order to find its duration. At some point,
an EOS event there would cause any queue2 upstream to pause and
not restart on a seek back to the beginning. This now appears to
not be the case anymore, and so the workaround can be removed.

6c84f4e743 Revert "vorbisenc: push an updated segment stop time when we know it"
This reverts commit a16cd5d2a5.

Setting the stop time on the segment breaks reconfiguration, as the
encoder signals an EOS, but we reconfigure it an continue to produce
buffers.

This information  should not be required via the segment downstream
since we already have the sample count being used to generate buffer
durations.

_get_gl_context() can be called concurrently from either propose_allocation() or

the check for whether we already had a GL context was outside the lock.  Inside
the lock and loop, the first thing that happens is that we unref the current GL
context (if valid) as if there was a conflict adding it to the display.  If the
timing was unlucky, subsequent use of the GL context would be referencing an
already unreffed GL context object resulting in a critical:

1ef601e7d3 opus: fix FEC
FEC may only be used when PLC is enabled on the audio decoder,
as it relies on empty buffers to generate audio from the next
buffer. Hooking to the gap events doesn't work as the audio
decoder does not like more buffers output than it sends.

The length of data to generate using FEC from the next packet
is determined by rounding the gap duration to nearest. This
ensures that duration imprecision does not cause quantization
to 2.5 milliseconds less than available. Doing so causes the
Opus API to fail decoding. Such duration imprecision is common
in live cases.

The buffer to consider when determining the length of audio
to be decoded is the previous buffer when using FEC, and the
new buffer otherwise. In the FEC case, this means we determine
the amount of audio from the previous buffer, whether it was
missing or not (and get the data either from this buffer, or
the current one if the previous one was missing).

4df2ffaad6 opusenc: Encode exactly the amount of samples we got as input and put correct timestamps on it
The first frame has lookahead less samples, the last frame might have some
padding or we might have to encode another frame of silence to get all our
input into the encoded data.

This is because of a) the lookahead at the beginning of the encoding, which
shifts all data by that amount of samples and b) the padding needed to fill
the very last frame completely.

Ideally we would use LPC to calculate something better than silence for the
padding to make the encoding as smooth as possible.

With this we get exactly the same amount of samples again in an
opusenc ! opusdec pipeline.

81a78449d5 glvideomixer: swap control binding proxy
The ref_object and object parameters were the wrong way around.

For the typical use case where an application is setting a
GstControlBinding on the returned ghost pad:
1. our control binding would be removed when the new one was set
2. sync_values calls were not being forwarded from the internal
   pad to the ghost pad.

If an application attempts to perform other control binding
operations (get_* family of functions) on the internal pad, they
will also be forwarded to the ghost pad where a possible
GstControlBinding will provide the necessary values.

5830db7050 textoverlay: Query downstream caps for checking if caps features are supported, not just accept-caps
accept-caps is not recursive and might stop at the next downstream element,
while caps queries are generally recursive. The next element might accept any
capsfeatures we want, but that doesn't mean that further downstream it will
also work.

Additionally for the future:
We should probably check if downstream *prefers* the
overlay meta, and only enforce usage of it if we can't handle
the format ourselves and thus would have to drop the overlays.
Otherwise we should prefer what downstream wants here.

d4759f05f1 basetextoverlay: Use the extents rectangle for positioning
the extents rectangle is what you need to know to properly position
a buffer that has been rendered in a surface of the ink rectangle
size. This patch make the placement on par with the placement we had
before without having to over allocate.

This patch also enable placement for vertical rendering. Note that
the halginement, valighment and line-alignment default are set to
the previous default when this property is set. This is for backward
compatibility, you can change the value after setting vertical render.

transformation matrix as the ink_rect position might not be at
0, 0. Additionally, shadow_offset and outline_offset (which is
in fact the diameter of a dot, not a really an offset) is now
taken into account. Redundant matrix operation has been removed
for the vertical rendering.

Take note that the matrix operation in cairo are excuted in
reverse order.

upstream have done that query already before making this decision. This
is an optimization since doing allocation queries is relatively

0a3b584aa0 Revert "oggdemux: Prevent seeks when _SCHEDULING_FLAG_SEQUENTIAL is set"
This reverts commit 76647f2710.

Avoiding pull mode activation is a feature regression, and
demuxers should always use pull mode where that is possible,
e.g. if there's an upstream queue2 with a ring buffer or
a download buffer.

This patch made reverse playback no longer possible over http.

If the goal is to minimise seeks, then that can still be done
by making the demuxer behave differently in pull mode if
the SEQUENTIAL flag is set. If there are bugs, like the demuxer
needlessly scanning the entire file on start-up in pull mode,
then those should be fixed instead.

index. However, when part of the stream is captured, the index is
invalid as its offsets are now wrong. To avoid this, we ignore the index
when the last offset points beyond the end of the stream (when its
byte length is known).

b590a843f4 oggmux: fix deadlock when not pulling a buffer from collectpads
oggmux keeps a cached buffer per pad, and pulls buffers from
collectpads to this cached buffer for all pads before processing
the best pad. In some cases, the move from collectpads buffer
to cached buffer is delayed till next call. However, when there
is only one pad, this can't be delayed till next call as there
will be a deadlock since collectpads has no other pad to push to.

This will usually deadlock, despite this patch being in master for

969cf47a82 oggdemux: add non flushing time seeking in push mode
Some resetting code has to be done in the NEW_SEGMENT
event handler, instead of the missing FLUSH_STOP one.

Segment base was also wrongly accounted for. This was hidden
by the fact that flushing resets the base.

A discontinuity is now also signalled on seeking. We have to
also ensure that the discontinuity "sticks" till a buffer
with a valid timestamp goes out, or the audio decoder base
class will ignore the discontinuity for purposes of keeping
track of the current time.

This allows using non flushing segment seeks for looping
HTML audio in particular, and more generally non flushing seeks.

ca136e3648 oggdemux: fix wrong first granule
The code was using the first nonnegative granulepos to seed the
granule tracking, which appeared to work since headers have zero
granulepos. However, this does not work for files with a hole at
start, which are common in live streaming.

The correct behavior is to look for the first granule, and subtract
the duration of all the packets finishing on this page.

The function which does this relies on the fact that the ogg_stream
structure can be duplicated by shallow copy, in order to pull the
packets from the first page(s) on the copy without affecting the
original stream state.

gst_gl_download_perform_with_data to take the texture target as an argument.

This change is needed to support wrapping textures created outside libgstgl,
which might be bound to a target other than GL_TEXTURE_2D. For example on OSX
textures coming from VideoToolbox have target GL_TEXTURE_RECTANGLE.

With this change we still keep (and sometimes imply) GL_TEXTURE_2D as the
target of textures created with libgstgl.

The previous code was setting keytarget to target

Then if target == keytarget, it assumed a keyframe had been

This patch checks that a keyframe was indeed found, and if not
seeks to 0, without bisecting again.

46e727ebde Revert "basetextoverlay: Fix segfault when overlay outside the frame"
This is not correct. overlay->silent is a property and we
should not just flip the property forever because one text
we render is outside of the frame. The next one might not
be, the positioning properties can be changed after all.

The lower layers should handle clipping, and now do.

This reverts commit 1cc311156c.

This is not right, even if it might avoid a crash. We don't
want to just set xpos/ypos to 0 in those cases. Clipping
should be done properly, see bug #739281 for that.

03c21f78b6 glupload: provide the output buffer that is rendered into
Allows callers to properly reference count the buffers used for
rendering.

Fixes a redraw race in glimagesink where the previous buffer
(the one used for redraw operations) is freed as soon as the next
buffer is uploaded.

1. glimagesink uploads in _prepare() to texture n
1.1 glupload holds buffer n
2. glimagesink _render()s texture n
3. glimagesink uploads texture n+1
3.1 glupload free previous buffer which deletes texture n
3.2 glupload holds buffer n+1
4. glwindow resize/expose
5. glimagesink redraws with texture n

The race is that the buffer n (the one used for redrawing) is freed as soon as
the buffer n+1 arrives.  There could be any amount of time and number of
redraws between this event and when buffer n+1 is actually rendered and thus
replaces buffer n as the redraw source.

not correct, it should be:

if (overlay->want_shading) {
    double alpha = overlay->shading_value / 255.0;
    cairo_paint_with_alpha (cr, alpha);
  }

however I think this code could be removed, we already do a shaded background,
why shade the box behind the text with cairo too? only one shading is needed so
we must shade with cairo or with methods like these:

Make textoverlay negotiate caps more correctly.

1) Check what caps we received in the video-sink
2) If it already has the overlay meta -> use it directly
3) If it doesn't, textoverlay try adding the overlay meta and using it,
   if downstream doesn't support it, just use what is received in the
   video-sink
4) Check if the allocation query also supports the meta to enable
   really using it

Before it wasn't really doing renegotiation of any kind, just
re-checking if it should use the overlay meta or not

Also had to update the caps in the test as memory:SystemMemory seems
to be required when you use a caps feature otherwise intersection/subset
checks will fail.

3b2d583373 alsasink: fix occasional crash intersecting invalid values
When a pipeline using alsasink and push mode upstream fails
to preroll, the following state will be the case:
- A loop upstream will be PAUSED, pushing a first buffer
- alsasink will be READY, pending PAUSED, because async

On error, the pipeline will switch to NULL. alsasink is in
READY, so goes to NULL immediately. It zeroes its cached
caps. Meanwhile, the upstream loop can cause a caps query,
conccurent with the state change. This will use those cached
caps. If the zeroing happens between the NULL test and the
dereferencing, GStreamer will critical down in the GstValue
code.

Since it appears that such a gap between states (PAUSED
and pushing upstream, and NULL downstream) is expected, we
need to protect the read/write access to the cached caps.

This fixes the critical.

b532ce16a5 oggdemux: fix broken seeking reading the whole file
A change in gst_ogg_demux_do_seek caused oggdemux to wait for
a page for each of the streams, including a skeleton stream if
one was present. Since Skeleton only has header pages, that
was never going to end well.

Also, the code was skipping CMML streams when looking for pages,
so would also have broken on CMML streams.

Thus, we change the code to disregard Skeleton streams, as well
as discontinuous streams (such as CMML and Kate). While it may
be desirable to consider Kate streams too (in order to avoid
losing a subtitle starting near the seek point), this may be
a performance drag when seeking where no subtitles are. Maybe
one could add a "give up" threshold for such discontinuous
streams, so we'd get any page if there is one, but do not end
up reading preposterous amounts of data otherwise.

In any case, it is important that the code that determines
the amount of streams to look pages for remains consistent with
the "early out" conditions of the code that actually parses
the incoming pages, lest we never decrease the pending counter
to zero.

This fixes seeking on a file with a skeleton track reading all
the file on each seek.

25bf5a13f0 oggdemux: use an adaptive chunksize for performance reasons
Ogg data is read chunk by chunk, and the chunk size used was
originally taken from libvorbisfile. However, this value leads
to poor performance when used on an Ogg file with large pages
(Ogg pages can be close to 64 KB).

We can't just use a larger chunk size, since this will decrease
performance on small page streams, so we use an adaptive scheme
where the chunk size is twice the largest page size we've seen
so far in the stream. For "typical" Ogg/Vorbis, this gives us
almost the same chunk size (a bit lower), and this lets us get
better performance on streams with large pages.

When bisecting after an earliest time has been found, we need

Before, the following scenario could be and was encountered:

a) Find the earliest time for stream X
b) bisect and find a page which granuletime is indeed < target, but
   contains another stream.
c) decide to seek at the wrong offset, sometimes inferior to
   the real one, in which case the error was undected or
d) the offset was superior, and thus the actual target keyframe was
   not processed, and packets were skipped waiting
   for a granulepos.

da673880eb theoraenc: do not reset the encoder when we need a keyframe
Instead, remember we need a keyframe, and we will force the encoder
to emit one next time we submit a new frame.
Since libtheora does not have an API to request a keyframe, we reset
the max keyframe interval to 1 temporarily.

This has the advantage that the rate control keeps its history,
and that the encoder won't choose different quant tables or
somesuch, thus requiring new streamheaders (although this is
probably only a theoretical possibility). Should also be a
bit faster than resetting the encoder.

67a7b5a993 alsasink: don't use 100% CPU
The root cause is that alsa-lib is not thread safe for the same handle.
There are two threads in the gstreamer accessing alsa-lib not serilized.
The race condition happens when one thread holds the old framebuffer app_ptr
position in the kernel, another thread advances the framebuffer app_ptr.
when the former thread is scheduled to run again, it overwrites the app_ptr
to old value by copying from kernel.Thus,the app_ptr in the upper
alsa-lib(pcm_rate) become one period size more advanced than the lower
alsa-lib(pcm_hw & kernel).

gstreamer uses noblock and poll method to communicate with the alsa-lib.
The app_ptr unsync situation as described above makes the poll return immediately because
it concludes there is enough space for the ring-buffer via the low-level alsa-lib.
The write function returns immediately because it concludes there is not enough
space for the ring-buffer from the upper-level alsa-lib. Then the loop of poll
and write runs again and again until another period size is available for
ring-buffer.This leads to the cpu 100 problem.

delay_lock  is used to avoid the race condition.

1e329bb4f4 alsa: fix supported format detection
The format probing code was assuming there'd be one caps
structure for each separate width/depth combination like
we did in 0.10 all over the place: for one, we'd query
unsigned/signed formats together for the same width/height,
and we'd add the entire current structure to the probed
caps when we find a format is supported. Now that we have
all raw formats in a single structure, this is all not going
to work so well any more. We added the entire structure with
all possible formats to the caps if we support just one format.

Fix probing so that we only return the list of actually
supported raw audio formats (with native endianness) from
get_caps().

it makes assumptions that are not necessarily true here,

Pick delta pad earlier during header parsing, and pick it based
on whether it's a video stream or not rather than some rather
byzantine signalling from theoraenc etc. which would set the delta
flag on header packets which oggmux would then pick up and determine
that this is a "delta-able" stream.

Since the new videodecoder-based theoraenc didn't do that any more,
we would only see the first delta flag on the second video packet,
which is after we've already muxed a few audio packets flagged as
key units, which trips up the unit test.

a1d2abbde6 audiovisualizer: shorten base class name
As suggested on IRC rename to AudioVisualizer. We use custom suffix on the type
to avoid clashing with other copies for the time being.

673dafd09d oggmux: only drop flushing seeks after we started to mux
Don't drop all seek events. It is okay to seek before we send the headers. Non
flushing seeks are okay at any time later as well.

566b5c4d1d visual: use right base class name
Rename to GstAudioBaseVisualizer. Also avoids conflict with a base class with
the same name in -bad.

5e6abc449b visual: port to baseaudiovisualizer
Add a copy of the base class until it is stable. Right now the extra effects of
the baseclass are not supported as the sublass overwrites the buffer instead of
blending.

1396f804be pango: only map video buffer memory if actually needed
No need to map the video buffer if we're just going to attach
the meta; but if we map, we should do so in READWRITE mode.

52056653be pango: pass pre-multiplied alpha to overlay composition directly
We now support pre-multiplied alpha in the overlay composition API,
and can avoid multiple conversions if the the overlay also supports
pre-multiplied alpha. We should probably also have mapped the
buffer as READWRITE when unpremultiplying.
