By passing NULL to `g_signal_new` instead of a marshaller, GLib will
actually internally optimize the signal (if the marshaller is available
in GLib itself) by also setting the valist marshaller. This makes the
signal emission a bit more performant than the regular marshalling,
which still needs to box into `GValue` and call libffi in case of a
generic marshaller.
Note that for custom marshallers, one would use
`g_signal_set_va_marshaller()` with the valist marshaller instead.
This adds two properties:
* scte-35-pid: If not 0, enables the SCTE-35 support for the current
program. This will write the proper PMT and send SCTE-35 NULL
commands (i.e. heartbeats) at a regular interval
* scte-35-null-interval: This specifies the interval at which the
NULL commands should be sent
Sending SCTE-35 commands is done by creating the appropriate SCTE-35
GstMpegtsSection and then sending them on the muxer. See the
associated example
Commit 8a56a7de6d (camerabin2: preview:
Appsink doesn't need to sync) add a line that set the "sync" property on
the appsink. However, the author seems to forget that there's another
property setting on appsink a few lines below.
It's very likely that the added line is required because the original
line doesn't take effect (maybe because it's too late). But for whatever
reason, the original line is now redundant. So, I remove it in this
commit.
GstTranscoder adds extra_args for gir which call gst_init() during
introspection. These extra arguments are the same as the standard
ones defined in the top level meson.build as "git_init_section",
However, the top level definition also ensures an empty plugin
repository is used.
Because GstTranscoder does not use the standard args, plugins get
loaded when it is introspected. Since some of the plugins fail
without specific hardware, this causes #1100.
This patch makes it use gir_init_section.
Fixes#1100.
Some hardware decoders, for example Hantro G1, have to be told the
size of the pic_order_cnt related syntax elements pic_order_cnt_lsb,
delta_pic_order_cnt_bottom, delta_pic_order_cnt[0], and
delta_pic_order_cnt[1] in bits.
Some hardware decoders, for example Hantro G1, have to be told the size
of the dec_ref_pic_marking() syntax element in bits. Record the size so
it can be passed on to the hardware.
The calculated size of short_term_ref_pic_set is not a part of
HEVC syntax but the value is used by some stateless decoders
(e.g., vaapi, dxva, vdpau and nvdec) for the purpose of skipping
parsing the syntax by the accelerator.
Add num_ref_idx_active_override_flag and sp_for_switch_flag to
member of GstH264SliceHdr. No reason to hiding them and
some decoder implementations (e.g., DXVA) rely on externally parsed header
data which can be provided by h264parser.
* Fix meson build script for Windows. Since the Vulkan dependency
object was declared by us in case of Windows, the dependency object
shouldn't be used for finding header
* Fix build error by including Windows specific header
gstvkdisplay.c(563): error C2065: 'VK_KHR_WIN32_SURFACE_EXTENSION_NAME': undeclared identifier
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.
Fix gst_event_new_seek call in gst-libs/gst/player/gstplayer.c
If rate >= 0.0, then previous code doesn't set end of segment. So, the end of segment
will be in place where previous seek put it. This is not neccesary end of media file
(in case of reverse playback). So if we play video backward for some time and then
switched to forward playing, we will get EOS somewhere in the middle of media file.
This commit always sets end of segment, thus fixing this bug
During resizes, the VkQueuePresent can return OUT_OF_DATE and if a buffer
is displayed returning OUT_OF_DATE it would error out and stop the pipeline.
We already have a explicit check for OUT_OF_DATE and the same general
error check in the statements following so just use that code.
NULL checking the main_context does not help as we've just destroyed the
GMainContext and set that field to NULL, not to mention it's unnecessary.
Fixes a leak of display's GSource.
Add a separate epb_cache variable to the codecparser NalReader to
detect Emulation Prevention Bytes separately from the main bit cache.
This fixes problems where the existing logic can mistakenly detect
multiple EPB with a sequence like: 0x00 0x00 0x03 0x00 0x03. In that
case, the 5th byte should not be regarded as an EPB.
