Sebastian Dröge e59962850a dtlsenc: Don't warn on GST_FLOW_FLUSHING or GST_FLOW_EOS 
Only warn if pushing a buffer returns an actual error to not pollute
logs with confusing warnings.

Sebastian Dröge 0dc783d719 timecodestamper: Refactor LTC audio waiting and properly handle live inputs 
If one of the inputs is live, add a latency of 2 frames to the video
stream and wait on the clock for that much time to pass to allow for the
LTC audio to be ahead.

In case of live LTC, don't do any waiting but only ensure that we don't
overflow the LTC queue.

Also in non-live LTC audio mode, flush too old items from the LTC queue
if the video is actually ahead instead of potentially waiting forever.
This could've happened if there was a bigger gap in the video stream.

Seungha Yang 85233eb968 tests: Add simple d3d11colorconvert unit test 2019-12-28 05:43:44 +00:00
Seungha Yang 81dde0f5b8 d3d11: Aggregate d3d11 memory usage query for dynamic-usage type decision 
Even if one of downstream d3d11 elements can support dynamic-usage memory,
another one might not support it. Also, to support dynamic-usage,
both upstream and downstream d3d11device must be the same object.

Seungha Yang d731bcb18a d3d11colorconvert: Remove device type dependent behavior 
If d3d11colorconvert element is configured, do color space conversion
regardless of the device type whether it's S/W emulation or real H/W.
Since d3d11colorconvert is no more a child of d3d11videosinkbin,
we don't need this behavior. Note that previous code was added to
avoid color space conversion from d3d11videosink if no hardware
device is available (S/W emulation of d3d11 is too slow).

Seungha Yang 46186356ca d3d11colorconverter: Fix unmatched lock/unlock pair 2019-12-28 05:43:44 +00:00
Seungha Yang ab80c771df d3d11upload: Don't hard overwrite caps features to support d3d11 memory passthrough 
d3d11upload should be able to support upstream d3d11 memory, not only system memory.

Fix for following pipeline
d3d11upload ! "video/x-raw(memory:D3D11Memory)" ! d3d11videosink

Nicola Murino a2cfd93891 opencv: allow compilation against 4.2.x 2019-12-26 22:43:35 +01:00
Seungha Yang 5298d95195 d3d11window: Make use of partial presentation with IDXGISwapChain1::Present1 
Since we might draw on partial area of backbuffer in case of force-aspect-ratio,
presenting only updated area is more efficient way.

Seungha Yang 487a41d312 d3d11videosink: Add support for overlay composition 
Add d3d11overlaycompositor object to draw overlay image
on render target using Blend method.

Seungha Yang a5295509af d3d11: Enable dxgi debug layer and always try to pop d3d11/dxgi debug message if possible 
Note that dxgi and d3d11 sdk debug will be enabled on debug build

Seungha Yang 49bccf0433 nvcodec: Refactor plugin initialization 
Create CUDA context per device, instead of per codec and encoder/decoder.
Allocating CUDA context is heavy operation so we should reuse it
as much as possible.

Seungha Yang 2a3205b294 vulkan/window/win32: Don't post any WinProc message to parent window 
Posting any message to parent seems to be pointless. That might break
parent window.
Regardless of the posting, parent window can catch mouse event
and also any keyboard events will be handled by parent window by default.

Aaron Boxer cd0c07e899 openjpegenc: add support for sub-frame encoding 
Following the standard for low latency JPEG 2000 encoding
https://www.itu.int/rec/dologin_pub.asp?lang=e&id=T-REC-H.222.0-200701-S!Amd1!PDF-E&type=items
we divide the image into stripes of a specified height, and encode
each stripe as a self-contained JPEG 2000 image. This MR is based on

Yeongjin Jeong 663aeb2131 svthevcenc: Add new SVT-HEVC encoder element 
The SVT-HEVC (Scalable Video Technology[0] for HEVC) Encoder is an
open source video coding technology[1] that is highly optimized for
Intel Xeon Scalable processors and Intel Xeon D processors.

Yeongjin Jeong 3f2240498b h265parser: Add simple GstH265Profile/string public utilites 
It makes more simplifies the conversion between GstH265Profile and string.

Seungha Yang 0e013fe539 d3d11videosink: Use dynamic texture for fallback buffer 
Upload CPU memory to texture directly by using dynamic usage texture.
This will reduce at least one step of staging copy per frame.
 2019-12-20 19:21:02 +09:00
Seungha Yang 65cace22e2 d3d11colorconvert: Set TRANSFER_NEED_DOWNLOAD flag to output memory for later cpu access 
Otherwise CPU cannot access texture via gst_memory_map()
 2019-12-20 19:21:02 +09:00
Seungha Yang 18e13404a2 d3d11colorconvert: Use shader resource and render target bind flags together 
The output of d3d11colorconvert would be used for rendering (i.e., shader resource)
 2019-12-20 19:21:02 +09:00
Seungha Yang 62c8d19e01 d3d11window: Change aspect-ratio mode from window thread 
Call DXGI API from window thread as much as possible
 2019-12-20 19:21:02 +09:00
Seungha Yang 187cb02d52 examples: Add example for d3d11videosink 
This is fork of win32-videooverlay in -base but more d3d11videosink specific one.
 2019-12-20 19:21:02 +09:00
Seungha Yang 1b687d556a d3d11videosink: Add support for full screen mode 
borderless top-most style full screen mode support.
Basically fullscreen toggle mode is disabled by default. To enable it
use "fullscreen-toggle-mode" property to allow fullscreen mode change
by user input and/or property.
 2019-12-20 19:21:02 +09:00
Seungha Yang 0788492461 d3d11: Use GRecMutex to protect immediate context and dxgi API call 
In some cases, rendering and dxgi (e.g., swapchain) APIs should be
called from window message pump thread, but current design (dedicated d3d11 thread)
make it impossible. To solve it, change concurrency model to locking based one
from single-thread model.

Seungha Yang a0a85cd80c d3d11window: Prefer to use flip-sequential over discard 
flip-sequential is more efficient than discard
 2019-12-20 11:15:12 +09:00
Seungha Yang 1424de0a4a d3d11window: Don't hold backbuffer interface 
We don't need to hold it
 2019-12-20 11:15:12 +09:00
Seungha Yang 32d618c677 d3d11window: Use CreateSwapChainForHwnd if available 
That's recommended way from MS and CreateSwapChainForHwnd supports
more options than CreateSwapChain
 2019-12-20 11:15:12 +09:00
Seungha Yang 9fd0b62f2d d3d11: Use configuration file for dxgi header version check 2019-12-20 11:15:12 +09:00
Seungha Yang 23b47a7ec1 d3d11window: Use allow-tearing mode if device supports it 
As the recommendation from MS.
 2019-12-20 11:15:12 +09:00
Seungha Yang 72b6b3557d d3d11window: Disable fullscreen mode change by alt + enter 
Disable full screen mode change until proper handling is implemented
 2019-12-20 11:15:12 +09:00
Seungha Yang 9dada90108 d3d11videosink: Remove resizing window hack and unify resizing flow 
In earlier implementation of d3d11videosink where no shader was implemented,
the aspect ratio and render size were adjusted by manipulating the backbuffer size
with unintuitive formula. Since now we do color conversion and resize using
shader, we can remove the hack.
 2019-12-20 11:15:12 +09:00
Seungha Yang 61cb6b2bbe d3d11: Pass GstD3D11Memory object to ensure_{shader_resource,render_target}_view methods 
The method name indicates it should be d3d11memory, so passing
GstD3D11Memory seems to make more sense than GstMemory.
 2019-12-20 11:15:12 +09:00
Seungha Yang 7c041f1934 d3d11videosink: Don't specify crop meta to allocation query 
d3d11videosink could not handle it for now
 2019-12-20 11:15:12 +09:00
Nicolas Dufresne 416728f213 autoconvert: Fix lock-less exchange or free condition 
Before this change, we would free the list we just have saved.

Fixes #1158

Francisco Javier Velázquez-García (francisv) c7fe1e8164 gstsrtsink: Add wait-for-connection property to srtsink 
Add `wait-for-connection` property to `srtsink` element.  This
property allows the element to process packets even when no clients
are connected.

Aaron Boxer c8193b1615 d3dvideosink: hold class lock for entire duration of class destruction 
This avoids a race condition currently when temporarily releasing the
lock and then re-acquiring.

Aaron Boxer 7cb6dbefba d3dvideosink: improve concurrency on hidden window create/destroy 2019-12-18 13:15:06 -05:00
Aaron Boxer eff0117b5a d3dvideosink: use thread pool to handle events from hidden window event queue 
window event queue now does not lock on the class lock, so we can now shut
it down without releasing the class lock, thus avoiding a potential race when
stopping the sink.
 2019-12-18 13:15:06 -05:00
Aaron Boxer 027eb5ef20 d3dvideosink: improve concurrency on internal window create/destroy 
Remove timeout and rely on condition variable instead to indicate thread
start.
