Should keep a strong reference to the device, but we don't need to manage
the reference count of elements of an NSMutableArray as it takes care of
that for us.
This element makes use of the documented AVFoundation framework made
available starting with iOS 4.0, and hence this means we can finally
capture video using a public API.
Also rename the relevant API so we mirror the public API more closely, and
switch to CoreFoundation CFTypeRef style typedefs. We still support the old
private CoreMedia in order to not break OS X support.
This means that vtenc and vtdec are now compatible with iOS 4.x, and in
theory also future versions of OS X, where this API may turn public like
it has on iOS.
GetOverlappedResult() might never return with some drivers. Time out
after 1000 ms. We cannot really fix this without either:
1) Controlling the streaming thread so we can do CancelIo() from that
thread.
2) Switch to using IO completion ports.
Turns out that the reference implementation does this, hence we need to
mirror this behaviour. This typically happens with hardware that takes
some time to initialize.
Most important part here is special-casing "device busy" so the application
is able to provide better feedback when another application is using the
device.
* Make the driver write directly into each GstBuffer to avoid memcpy().
* Don't memset() the buffer before reusing it.
* Recycle memory by keeping two spare buffers. Two because the sink
downstream may keep a ref to the previous buffer.
Note that we align buffers on highest possible byte boundary (4096) so we
don't have to take into account what kind of alignment the driver requires.
Provides the following elements:
qtkitvideosrc: OS X video source relying on the QTKit API. Comes with
hard-coded caps as the API does not provide any way of querying for
formats supported by the hardware. Hasn't been tested a lot, but seems
to work.
miovideosrc: OS X video source which uses the undocumented/private
CoreMediaIOServices API, which is also the one used by iChat.
Present on latest version of Leopard and all versions of Snow Leopard.
Has been tested extensively with built-in cameras and TANDBERG's
PrecisionHD USB camera.
vtenc, vtdec: Generic codec wrappers which make use of the undocumented/
private VideoToolbox API on OS X and iOS. List of codecs are currently
hard-coded to H.264 for vtenc, and H.264 + JPEG for vtdec. Can easily be
expanded by adding new entries to the lists, but haven't yet had time to
do that. Should probably also implement probing as available codecs depend
on the OS and its version, and there doesn't seem to be any way to
enumerate the available codecs.
vth264decbin, vth264encbin: Wrapper bins to make it easier to use
vtdec_h264/vtenc_h264 in live scenarios.
iphonecamerasrc: iPhone camera source relying on the undocumented/private
Celestial API. Tested on iOS 3.1 running on an iPhone 3GS. Stops working
after a few minutes, presumably because of a resource leak. Needs some
love.
Note that the iOS parts haven't yet been ported to iOS 4.x.
timestamps are now chosen in the following order:
upstream -> parsed by decoder -> calculated from timestamp offset
we also check the timestamps supplied from upstream/decoder to see if they
atleast is increasing.
This way we'll reuse the GstVdp[Video|Output]Buffers if they're of the same
size and chroma-type/rgba-format.
Also remove gst_vdp_output_src_pad_negotiate and set a "setcaps" function on
GstVdpOutputSrcPad instead, leaving negotiation to GstVdpVideoPostProcess.
instead we do as GstVdpVideoSrcPad and use the "templ" property of GstPad,
which enable us to change the signature of gst_vdp_output_src_pad_new to match
gst_pad_new_from_template
we now no longer try to get the GstVdpDevice from downstream since it in
practice didn't give us anything and complicates the code alot. Nevertheless if device
distribution should be done there's probably a lot better ways to do it.
Instead we now simply aquire the device in vdpauvideopostprocess when we're
going into PAUSED.

* Inherit from GstVideoSink
* Implement GstNavigation interface
* Proper COM initialization for threaded environments
* Fix Window resource leak
* Add EVR support for better video scaling on Windows Vista and above
* Only apply PAR scaling when the keep_aspect_ratio property is set to stay

* Prevent an infinite loop with the wndproc chain
* Fix debugging messages to use the object instance
A new virtual method has been added to the RendererSupport class. It
is called during the initial renderer configuration and each time the
force-aspect-ratio property of the sink is updated.
Fixes bug #623272.
The current URI parsing code doesn't allow setting the "device"
from which the VCD should be read.
Use the same structure as the DVD URI handling instead, so that
devices can be passed in the URI, as well as track number.
Up the rank of the VCD plugin so that it can be auto-plugged and
used by Totem.
https://bugzilla.gnome.org/show_bug.cgi?id=340986
Move include directives for gst-libs into GST_PLUGINS_BAD_CFLAGS,
and fix all the Makefiles that use it. This is so that all the
include directories are added in the proper order: first the
directories in srcdir/builddir, then gst-plugins-base dirs, then
gstreamer dirs. If the order is wrong, installed headers may be
used instead of local headers and/or uninstalled headers from -base.
gst_vdp_output_src_pad_push, gst_vdp_output_src_pad_alloc_buffer and
gst_vdp_output_src_pad_get_device now take a GError parameter to be able to
signal errors to the caller
OSS4 supports per-stream volume control, so expose this using the right
API, so that playbin2 and applications like totem can make use of it
(instead of using a volume element for volume control).
Fixes#614305.
When iterating the formats table, we can just pass the whole
entry to our helper function, which avoids iterating the table
again to find the entry structure from the passed format id.
Also accept formats that are not natively supported by the
hardware, OSS4 can convert them internally. List the native
formats first in the caps though, to express our preference
for the native formats. We need this in order to support the
case properly where the audio hardware supports only e.g.
little endian PCM, but the host is big endian, since many
audio elements only support native endianness and make the
reasonable assumption that any audiosink will be able to
handle audio in native endianness.
Based on patch by Jerry Tan <jerry.tan@sun.com>
Fixes#614317.
A side effect is that it passes -Wformat-nonliteral and doesn't read
invalid memory in some cases, like when the mixer track contains
a % sign or there is a number but not a known mixer name.
GstVdpOutputSrcPad is a subclass of GstPad that is used for pushing out
GstVdpOutputBuffers. It takes care of caps negotiation and conversion to
video/x-raw-rgb.
The library contains GstVdpDevice GstVdpVideoBuffer and GstVdpOutputBuffer. The
library will (apart from the plugins here) be used by the upcoming gst-ffmpeg
vdpau support.
vdpausink is as the name implies a sink which takes vide/x-vdpau-output buffers
and outputs it to the screen.
vdpauvideopostprocess is an element which takes video/x-vdpau-video buffers and
outputs video/x-vdpau-output buffers. The element can also do things like
deinterlacing and other postprocessing but this is not implemented yet.
One set of CFLAGS for all DirectX-based plugins. Correct header/library
checks for DirectX-based-plugins. Remove unused variable and label in
directsoundsrc.
Fixes#593068.
These elements are not fit for autoplugging, so demoting to RANK_NONE.
Also blacklisting for generic states test, since fixing these elements
up to do some minimal error handling seems to be a bit more work.
Partially fixes#591538.
Even if the device could capture several video sizes at several framerates,
without this commit, it was only possible to use one video size and
one framerate: the default directshow values.
-remove gst-libs/gst/dshow
-fakesource is moved from gst-libs/gst/dshow to sys/dshowsrcwrapper
-some minor changes (C/C++ check and includes) to make the plugin
compile again.
Some devices take a while to tune and 500ms was too short to detect
successful tuning. As well as waiting for 5 seconds each 100ms the
status is checked and the loop is broken out of when tuning has suceeded.
Code cleanups, general improvements, support for the
new mixer flags in latest gst-plugins-base.
Fixes: #584252
Patch By: Brian Cameron <brian.cameron@sun.com>
Patch By: Garrett D'Amore <garrett.damore@sun.com>
Make I420/YV12 caps be preferred when downloading to YUV buffers,
when possible, by listing them first in the set of output caps.
Add some debug in the caps selection code.
Fix a typo in the caps for the VDPAU mpeg decoder (chroma_type->chroma-type)
and use the GST_VDP_VIDEO_CAPS for the pad template.
Remove a stray semicolon.
Check for the VDPAU headers in /usr/include/nvidia as they are on some
platforms (Fedora/rpmfusion). Also check that the libvdpau library is
available.
the buffers don't come in output order so fix the decoder to handle this
add new gst_vdp_video_buffer_add_reference method to GstVdpVideoBuffer to be able to keep
buffers alive. Ie. a B_FRAME need to have both the forward reference and the backward
reference alive during it's lifetime.
add mutex to protect for threadsafety issues when we reset the decoder in FLUSH_STOP
GstVdpauDecoder now pushes GstVdpauVideoBuffers instead of doing
VdpSurface -> YUV conversion. To get YUV data you now put in a GstVdpauVideoYUV
element which takes GstVdpauVideoBuffers and outputs YUV data.

Make it so that gst_directdraw_sink_buffer_alloc uses the right

Especially when looking through the pool of buffers, make sure that
the width/height of caps is used instead of the already negotiated
dimensions.
For example if a buffer with different caps is requested, i.e.
higher resolution, the caller would get a buffer with the old
dimensions and thus corrupt the heap.

Remove ENABLE_CLOCK_DEBUG define, it's GST_LEVEL_DEBUG after all.
Get rid of PROP_ENSLAVE_KSCLOCK and always slave the ks clock to the
GStreamer clock, it doesn't seem to hurt and matches DirectShow's
behavior. As an added bonus we usually get PresentationTime set for
each frame, so we can expand on this later for smarter latency
reporting (by looking at the diff between the timestamp from the
driver and the time according to the GStreamer clock).
Use an internal worker thread for opening the device, setting caps,
changing its state and closing it. This way we're a lot more
compatible with drivers that rely on hacks to do video-effects
between the low-level NT API and the application. Ick.
Start the ks clock and set the pin to KSSTATE_RUN on the first
create() so that we'll hopefully get hold of the GStreamer clock
from the very beginning. This way there's no chance that the
timestamps will make a sudden jump in the beginning of the stream
when we're running with a clock.
