The workaround for https://github.com/Intel-Media-SDK/MediaSDK/issues/1139
is required for vp8 only, so move this workaround to the corresponding
postinit_decoder function
The pipeline below works with this change
gst-launch-1.0 filesrc location=SA10104.vc1 ! \
'video/x-wmv,profile=(string)advanced',width=720,height=480,framerate=14/1 ! \
msdkvc1dec ! fakesink
MFXVideoDECODE_DecodeHeader only parses the sequence layer for VC1, so
the structure is unknown for a stream with interlace flag set in the
sequence layer. If forcing the struct to progressive in this plugin,
MediaSDK will fail to decode such streams.
It is possible MFXVideoDECODE_DecodeFrameAsync returns MFX_ERR_INCOMPATIBLE_VIDEO_PARAM
and this error can't be recovered by retrying MFXVideoDECODE_DecodeFrameAsync
in some cases, so we need to limit the number of retries to avoid infinite loop.
This fixes https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/issues/909
To drain all queued encoding items, encoder should gracefully
wait the encoding thread without stealing queued items.
Otherwise, some input frames can be dropped.
../subprojects/gst-plugins-bad/sys/msdk/msdk.c(61): error C2065: 'MFX_FOURCC_RGB565'
The minimum required version for the format seems to MFX_VERSION >= 1028
Returning MFX_ERR_INCOMPATIBLE_VIDEO_PARAM from
MFXVideoDECODE_DecodeFrameAsync means the allocated mfx surface is not
suitable for the current frame, we need a new mfx surface and try
MFXVideoDECODE_DecodeFrameAsync again.
When MFXVideoDECODE_DecodeFrameAsync () returns MFX_WRN_DEVICE_BUSY with
an output surface, a new input surface is required when retrying
MFXVideoDECODE_DecodeFrameAsync ().
This fixes the out-of-surface issue mentioned in
https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/issues/890
This gets rid of annoying message in the log, e.g. run the pipeline
below:
gst-launch-1.0 videotestsrc num-buffers=100 ! \
video/x-raw,format=NV12,width=352,height=288 ! msdkh264enc ! filesink \
location=test.h264
[LIBVA]:CRITICAL - DdiMedia_DestroyImage:4357: Invalid image
This make the pipeline below works:
gst-launch-1.0 videotestsrc num-buffers=1 ! msdkvpp ! \
video/x-raw,format=UYVY ! filesink location=a.yuv
Once https://github.com/intel/media-driver/pull/526 in the media-driver
is merged, the pipeline below also works:
gst-launch-1.0 videotestsrc num-buffers=1 ! msdkvpp ! \
video/x-raw\(memory:DMABuf\),format=UYVY ! filesink location=a.yuv
The VCD source was ported in 2014 (commit 89eb1e9), but the necessary
"cdxaparse" plugin, which is used to "Parse a .dat file (VCD) into
raw mpeg1" was never ported.
This means that the probable main user for the feature, totem, hasn't
actually been able to play back VCDs, since 2012, when it switched to
using GStreamer 1.0.
Note that even if cdxaparse was finally ported, a lot of work would
still be necessary before it is considered usable. Notably, it is
missing disc image support [1] and some VCDs just cannot be opened for
reading [2].

An output surface is returned but without sync point when when
MFXVideoDECODE_DecodeFrameAsync () returns MFX_ERR_MORE_DATA, this
surface should be released too, otherwise the surface is occupied
and it is easy to exhaust all pre-allocated mfx surfaces.
Example pipeline (input_vp8.webm contains lots of frame with show_frame
set to 0):
gst-launch-1.0 filesrc location=input_vp8.webm ! matroskademux !
msdkvp8dec ! msdkvpp ! fakesink

Fixes https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/issues/862
The picture structure in the output parameters from
MFXVideoDECODE_Query is set to MFX_PICSTRUCT_UNKNOWN for some codecs, so
the structure of the corresponding mfx surfaces created for decoding are
unknown. The pipeline will be broken when these surfaces are used as the
input for msdkvpp.
Example pipeline:
gst-launch-1.0 filesrc location=input_vp8.webm ! matroskademux !
msdkvp8dec ! msdkvpp ! fakesink
Error message:

This is a workaround for the above issue
The memory type was used as bitwise enum, but the enum was not
defined in that way.
Nonetheless, most of the usage of the memory type was as mutually
exclusive options, rather than option composition.
This patch refactor how the memory type is defined, so it is kept
the mutual exclusion among options.
'channel-mask' field should not be put in caps if channel mask is 0x0
Mapping WASAPI channel mask to GST equivalent was going only over
first nChannels elements of wasapi_to_gst_pos array, translating, for
example, WASAPI's 0x63f to GST's 0x3f instead of 0xc3f.
When 'channel-mask' is specified as NULL, it signifies that there's
need to do downmix or upmix and it makes caps negotiation with
audioconvert element impossible. Just omit it.

When building the msdk plugin even if libmfx is found, unless the
plugin is explicitly enabled we should not error out if msdk
dependencies are not found.
Also give an error message when we don't build the plugin on Windows
because we're not building with MSVC.
When the audio device goes away during playback or capture, we were
going into an infinite loop of AUDCLNT_E_DEVICE_INVALIDATED. Return -1
and post an error message so the ringbuffer thread exits with an error.
BRCParamMultiplier in mfxInfoMFX is a parameter which specifies a

According to the MSDK documation[1], MFXCloneSession is a light-weight
equivalent of MFXJoinSession after MFXInit, so MFXJoinSession call isn't
needed in the msdk plugin, otherwise the cloned session is joined to the
parent session twice, and we will get a MFX error when closing the
parent session
example pipeline:
gst-launch-1.0 videotestsrc num-buffers=100 ! \
video/x-raw,format=NV12,width=352,height=288 ! msdkh264enc ! msdkh264dec ! \
msdkh264enc ! fakesink
Error message:
0:00:00.211948518 21733 0x5586ee741c60 ERROR msdk

[1]: https://software.intel.com/en-us/node/628429#MFXCloneSession
In gst-msdk, a mfx session may be shared between different gst
elements, each element tries to set the frame allocator. However, per
the MSDK documation[1], the behavior is undefined if reset the frame
allocator while the previous allocator is in use. Fortunately all
elements use the same frame allocator, so we can avoid to call
MFXVideoCORE_SetFrameAllocator again.
[1]: https://software.intel.com/en-us/node/628430#MFXVideoCORE3
If so, BGRA is the preferred output format hence BGRA will be selected
as input format by default, e.g. in the pipleline below, BGRA instead of
NV12 is selected without renegotiation, so we can avoid the NV12 issue
(see commit 3f2314a) by default.
gst-launch-1.0 videotestsrc ! msdkvpp ! glimagesink
Otherwise MFXVideoVPP_Init will fail because it is called twice without
a close.
Example pipeline:
gst-launch-1.0 videotestsrc ! msdkvpp ! glimagesink
Sometimes glimagesink emits GST_EVENT_RECONFIGURE event which results
in that MFXVideoVPP_Init is called twice, then get the negotiation
failure below:
0:00:00.093715518 21218 0x558ef56231e0 ERROR msdkvpp
gstmsdkvpp.c:995:gst_msdkvpp_initialize:<msdkvpp0> Init failed
(undefined behavior)
WARNING: from element /GstPipeline:pipeline0/GstMsdkVPP:msdkvpp0: not
negotiated
After applying this commit, the pipeline above may run without
negotiation failure, however NV12 layout in dmabuf mode is selected in
renegotiation, the display image is corrupted due to the NV12 issue which
was mentioned in commit 3f2314a. Some other fixes are needed to avoid
renegotiation by default
In general, we should assume any unhandled error is
non-recoverable.
In the flush frames loop, some error states can cause us
to never increment the task and therefore we get stuck
in an infinite loop and generate GST_ELEMENT_ERROR
over and over again. This eventually consumes all
system memory and triggers OOM. Thus, assume the worst
and break out of the loop upon the first "unhandled" error.
https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/issues/859
When either the source or sink goes from PLAYING -> NULL -> PLAYING,
we call _reset() which sets client_needs_restart, and then we call
prepare() which calls IAudioClient_Start(), so we don't need to call
it again in src_read() or sink_write(). Unlike when we're just going
PLAYING -> PAUSED -> PLAYING.
configure_mode_setting() keeps a ref on tmp_kmsmem which is released in
gst_kms_sink_show_frame().
But if for some reason configure_mode_setting() is re-called before
showing a frame or if none is showed this memory was leaked.
ACM is an ancient legacy API, and there's no point in
keeping it around for a licensed mp3 decoder now that
mp3 patents have expired and we have a decoder in -good.
We didn't ship this in cerbero anyway. If there's a good
case for the AAC encoder (which is LC only anyway) someone
should write a new plugin based on current APIs, that can
actually be built out of the box.
Fixes#850
As a side-effect we can now actually store the line offset in the
line21dec element, and have to perform fewer transformations in the
decklink elements (which were also buggy as they assumed a single byte
triplet per meta).
We will add more profiles in the sink caps of msdkh265enc, so let
msdkh265enc re-add the sink pad template. Note this change doesn't
impact any capability
Fixes the time calculations when dealing with a slaved clock (as
will occur with more than one decklink video sink), when performing
flushing seeks causing stalls in the output timeline, pausing.
Tighten up the calculations by relying solely on the internal time
(from the internal clock) for determining when to schedule display
frames instead attempting to track pause lengths from the external
clock and converting to internal time. This results in a much easier
offset calculation for choosing the output time and ensures that the
clock is always advancing when we need it to.
This is fixup to the 'monotonically increasing output timestamps' goal
in: bf849e9a69
CodecProfile will be set in MFXVideoDECODE_DecodeHeader() to match
the input stream. Setting the hard-coded profile here will mislead
user that msdkh265dec supports a special profile only.
Previously alloc_info is initialized when both thiz->initialized
and thiz->allocation_caps are true, but only thiz->initialized is
checked when alloc_info is used.
Instead of relying on buffers after a state change to PLAYING to always start
from 0, track the amount of time we have spent outside playing but not changed
state to PAUSED.
Note that, since Nvidia does not provide nvEncodeAPI.lib file,
find_library() couldn't be used for build on Windows.
This patch changes to load nvEncodeAPI(64).dll or libnvidia-encode.so

dynlink_* was introduced since CUDA Toolkit 9.x but it's deprecated from 10.0.

MediaSDK has been released as open source [1], but the directories
where it installs its files, are different from the binary only
distribution.
This patch adds to the libraries path the directory /lib. Also it
is defined in meson if the include directory has the mfx/ prefix,
something that is already handled in autotools.

"required" keyword is not a valid argument for has_header()
WARNING: Passed invalid keyword argument "required".
WARNING: This will become a hard error in the future.
These function are not used at all, using them together with the
transport-volume property from avdtpsrc may end up in a binding loop so
we better remove the functions.
If properties are proxied through GBinding this can work only if the
proxied property keeps it's own value. The previous implementation will
read the original value if the proxied property signals a change and
thus nothing will happen.
Right now this only works for video. An attempt was made at adding
monitoring following the example winks, but it seems the only devices that
can be easily detected are KS sources, which winks already handles.
The previous behaviour had issues when setting one of the device properties
after _get_caps had been called. The device shouldn't be locked in until after
_start has been called.
the 2018.3.1 intel sdk release places libraries into /lib64 instead of
/lib/lin_x64 or /lib/x64, this commit adds /lib64 to the libdir
locations list
Fixes#815
Before this patch, if mode=auto and video-format!=auto, video-format would
always be ignored, and get set to 8bit-yuv, or if detected to be RGB444, then
it would be set to 8bit-argb. This change respects video-format if it is set
to 10bit-yuv (v210) or 8bit-bgra, even when mode=auto.
Closes#772
There's a race condition when is-live is set to true and the shmsrc
element releases the pipe in the transition from PLAYING to PAUSED.
To avoid it this change ensures that _create method takes the pipe
and increases the use_count in one operation protected by object lock.
Also perform apropriate protections when releasing the pipe.
