When the bitrate is changed in playing state the encoder issues a reconfig
that drains and recreates the underlaying hw encoder instance.
With this set of changes we ensure that all this work is only made when
the bitrate did actually change. It also tries to reuse the vpp buffer
pool and fixes the pool leak spotted when testing this feature.
hlssink2 defined "max-files" property to decide the maximum number
of fragments which should be stored in disk. But we've not used
the property. Instead, the size has been maintained by "playlist-length".
Since "max-files" and "playlist-length" have different meaning,
the decision should be done by "max-files" property.
For example, an user might want expose only 3 fragments via playlist
but might want to keep more files than 3 in disk.
A classic case of not updating the next item to iterate after deleting
it from the singly linked list.
Only ever hit with a text buffer with GST_CLOCK_TIME_NONE for either the
timestamp or duration.
hlssink* elements could be finalized without EOS event, and in that case
the final playlist might not include the EXT-X-ENDLIST tag.
Since missing ENDLIST tag means it's live stream, but we did't intend it,
hlssink* elements should put the tag at the end.
When postpone_free_surface is TRUE, the output buffer is not writable,
however the base decoder needs a writable buffer as output buffer,
otherwise it will make a copy of the output buffer. As the underlying
memory is always lockable, so we may set the LOCKABLE flag for this buffer
to avoid buffer copy in the base class.
The refcount of the output buffer is 1 when postpone_free_surface is
FALSE, so needn't set the LOCKABLE flag for this case.
... instead of calculated display ratio from given PAR and DAR.
d3d11window calculates output display ratio
to decide padding area per window resize event. In the formula,
actual PAR is required to handle both 1:1 PAR and non-1:1 PAR.
In Debian, soundfonts in SF3 format (i.e. the same as SF2 format but
with Ogg/Vorbis-compressed samples) are installed into
/usr/share/sounds/sf3. Soundfonts in SF3 format are supported since
FluidSynth 1.1.7 (released in Feb 2018).

The convert-error signal is emitted whenever we get a GstFlowReturn
other than GST_FLOW_OK. The handler can then decide what to convert that
into - for instance, return the same GstFlowReturn to not convert it.
The default handler will act according to the ignore-error,
ignore-notlinked, ignore-notnegotiated and convert-to properties. If a
handler is connected, these properties are ignored.

Both MSDK and this plugin use mfxFrameAllocResponse for video and DMABuf
memory, it is possible that some GST buffers are still in use when calling
gst_msdk_frame_free, so add a reference count in the wrapper of
mfxFrameAllocResponse (GstMsdkAllocResponse) to make sure the underlying
mfx resources are still available if the corresponding buffer pool is in
use.
In addtion, currently all allocators for input or output share the same
mfxFrameAllocResponse pointer in an element, so it is possible that
the content of mfxFrameAllocResponse is updated for a new caps then all
GST buffers allocated from an old allocator will use this new content of
mfxFrameAllocResponse, which will result in unexpected behavior. In this
fix, we save the the content of mfxFrameAllocResponse in the corresponding
tructure to avoid such issue
Sample pipeline:
gst-launch-1.0 filesrc location=vp9_multi_resolutions.ivf ! ivfparse ! msdkvp9dec !
msdkvpp ! video/x-raw\(memory:DMABuf\),format=NV12 ! glimagesink
Otherwise it is possible that different wrappers share the same
mfxFrameAllocResponse pointer, so instead of caching the pointer, we may
cache the content of mfxFrameAllocResponse
For a skipped frame in VC1, MSDK returns the mfx surface of the reference
frame, so we have to make sure the corresponding surface for the
reference frame is not freed. In this fix, we postpone surface free because
we don't know whether a surface is referenced
Before this fix, the error is like as below:
New clock: GstSystemClock
0:00:00.181793130 23098 0x55f8a9d622d0 ERROR msdkdec
gstmsdkdec.c:622:gst_msdkdec_finish_task:<msdkvc1dec0> Couldn't find the
cached MSDK surface
Sample pipeline:
gst-launch-1.0 filesrc location=input_has_skipped_frame.wmv ! asfdemux !
vc1parse ! msdkvc1dec ! glimagesink
If the surface is not in use, we may release it even if GST_FLOW_OK is going
to be returned, which may avoid the issue of failing to get surface
available
This fixes the regression caused by commit c05acf4
GstAllocationParams::align is set to 31 in msdkdec/msdken/msdkvpp, hence
the stride align should be greater than or equal to 31, otherwise it
will result in issue
https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/issues/861
(msdk: "GStreamer-CRITICAL: gst_buffer_resize_range failed" SPAM),
In addition, the stride should match the pitch alignment in the media driver,
otherwise it will result in some issues when a buffer is shared between
different elements, e.g. the NV12 issue mentioned in commit 3f2314a, which
can be reproduced by `gst-launch-1.0 vidoetestsrc ! msdkvpp !
video/x-raw\(memory:DMABuf\),format=NV12 ! glimagesink`
Fixed https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/issues/861
1. The iOS create_surface implementation needs to call out to the main
thread to create the window (UIKit requirement)
2. get_surface() can be called and will attempt to create the VkSurface
from an invalid view/layer.
Also pass the layer for MoltenVK so we don't get pesky 'UIView function
not called on main thread' warnings.
