On Wayland compositors whose xdg-desktop-portal backend exposes screencast
frames as DMA-BUF buffers — notably xdg-desktop-portal-cosmic 0.1.0 on
Pop!_OS 24.04 / COSMIC — inbound screen capture fails. PipeWireRecorder
links pipewiresrc directly to an appsink whose caps only accept
video/x-raw BGRx/RGBx in system memory. That format set is too narrow for
the portal's buffer-type / modifier negotiation, which collapses with:
pw.link: negotiating -> error no more output formats (-22)
gstpipewiresrc: stream error: no more output formats
gstbasesrc: streaming stopped, reason not-negotiated (-4)
ERROR src/server/wayland.rs: Failed scrap Element failed to change its state
Inserting a videoconvert element between pipewiresrc and appsink widens
the negotiable format set to any system-memory video/x-raw format, giving
the portal room to settle on a format it can deliver via its SHM path.
videoconvert then converts to the BGRx/RGBx the appsink expects.
Verified on Pop!_OS 24.04 / COSMIC with gst-launch, before and after:
# fails (current behaviour):
gst-launch-1.0 pipewiresrc path=N ! video/x-raw,format=BGRx ! fakesink
# works (with this change):
gst-launch-1.0 pipewiresrc path=N ! videoconvert ! video/x-raw,format=BGRx ! fakesink
After the change, inbound connections capture and stream the desktop
normally and the "Failed scrap" error no longer occurs.

* Updated build.rs to tell RustC that dxgi, quartz and x11 are expected configurations.
Added lifetime annotations to various methods in common/aom.rs and common/vpxcodec.rs.
Updated common/vpx.rs to allow unused_imports in the generated bindings.
Updated dxgi/mag.rs to allow non_snake_case identifiers like "dwFilterMode".
* Added lifetime annotations to methods in common/hwcodec.rs and common/vram.rs.
* Switched syntax for the rustc-check-cfg directive emitted by build.rs in the scrap crate to use syntax compatible with Rust toolchain version 1.75. The double-colon syntax requires 1.77 or newer, but the older single-colon syntax works fine on newer versions for this directive.
* Update libs/scrap/build.rs

* Revert apparently-erroneous AI suggestion. It's usually pretty good, but not always right it seems. :-)
This reverts commit bf862b13f6.
* Removed redundant configuration directives from libs/scrap/build.rs.

* Add Wayland multi-monitor screen capture functionality
* fix wayland capture issues by reverting to CapturerPtr, the problem was that calling Display::all in get_capturer_for_display was dropping the pipewire capturer and causing the video to freeze.

* Adjust bitrate and fps based on TestDelay messages.
* Bitrate is adjusted every 3 seconds, fps is adjusted every second and when receiving test lag.
* Latency optimized at high resolutions. However, when the network is poor, the delay when just connecting or sliding static pages is still obvious.

1. Dropping frames can cause this error, reset encoder when this
happens.
2. There are some logic error for clear video queue, because video queue
message is not cleared. This need to be fixed.

* Rotate ID3D11Texture2D after duplication with d3d11 video processor.
* If display is not rotated, nothing will be created; If the rotation
fails, it will use the old fallback logic
TODO:
* If changing from Landscape to Landscape(flipped) during capture, the resolution is
not changed, video service fallback to gdi directly.

* Sciter old issue, stop the process directly without stop record, the record file can't play.
