Add announcements and polish recording motion - #847
Conversation
Use practical bitrate targets across export backends and add dithering when converting full-range canvas frames to BT.709 video range.
Record captured frames with BT.709 conversion and explicit limited-range metadata. Share the Windows conversion code between capture engines and apply matching colour metadata on macOS and FFmpeg fallbacks.

In @.github/workflows/release.yml:
- Around line 634-637: Update the asset staging logic around the assets array so
it explicitly validates that each required update metadata file exists before
checksum generation: latest.yml and latest-linux.yml for the selected scopes,
plus latest-mac.yml when RELEASE_SCOPE=all. Fail the workflow if any required
file is missing, rather than relying on nullglob or the assets array being
non-empty.
In `@electron/ipc/nativeVideoExport.ts`:
- Around line 23-25: Replace sws_dither=a_dither with sws_dither=bayer in both
range-conversion filters in electron/ipc/nativeVideoExport.ts (lines 23-25) and
electron/ipc/recording/ffmpeg.ts (line 29), preserving the existing filter
behavior otherwise.
In `@electron/ipc/recording/ffmpeg.ts`:
- Line 29: Update commonOutputArgs and the AVFoundation input configuration to
avoid assuming full-range input: inspect the negotiated pixel format/range, then
apply the appropriate scale in_range conversion for each input, or force a known
pixel format and retain the matching conversion. Ensure video-range AVFoundation
input does not get processed as full-range.
In `@electron/ipc/register/announcements.ts`:
- Around line 63-67: Move the cache timestamp and validity updates out of the
finally block in the announcement fetch flow, and apply them only after the
response parses successfully. Ensure failed fetches leave the existing cache
state and TTL unchanged, while still clearing the timeout in finally.
In `@src/components/announcements/AnnouncementDialog.tsx`:
- Around line 210-214: Update AnnouncementDialog’s onOpenChange flow to dismiss
only the currently viewed announcement when the dialog closes, including via
Escape or outside click, rather than calling dismissAll. Respect the active
announcement’s controls.dismiss setting: do not persist dismissal when it is
false, while preserving normal dismissal for dismissible announcements.

FFmpeg avfoundation pixel_format default fallback range UYVY422 official documentation
💡 Result:
The FFmpeg avfoundation device does not have a hardcoded default fallback to UYVY422 [1][2]. Instead, its behavior is determined by the device's own capabilities [3]. When you specify a pixel format using the -pixel_format option, FFmpeg requests that format from the AVFoundation framework [1][4]. If the requested format is not supported by the capture device, FFmpeg retrieves a list of the device's supported formats and selects the first one from that list [1][2]. Historical development context shows that earlier versions of the avfoundation module sometimes defaulted to specific formats like yuv420p [5][3], but this was changed to improve compatibility [3]. The current implementation avoids forcing a single hardcoded default (like UYVY422) for all devices [3], which prevents failures on devices that do not support it [3]. Consequently, the "default" behavior is effectively whatever the hardware device prioritizes or reports as the first supported option in its capability list [1][3]. In summary: 1. There is no static fallback to UYVY422 [3]. 2. If your explicitly requested -pixel_format is unsupported, the device selects the first format from its internally enumerated list of supported formats [1][2]. 3. For reliable results, you can use -list_formats true with your device to see which pixel formats are actually supported by your specific hardware [1].

🌐 Web query:
site:ffmpeg.org/ffmpeg-devices.html avfoundation pixel_format list_formats supported format default
💡 Result:
The term "avfoundation" in the context of pixel formats, supported formats, and list_formats specifically refers to the AVFoundation device in FFmpeg, which is a wrapper for Apple's native AVFoundation framework. To interact with these settings using FFmpeg's avfoundation input device, use the following options: 1. List available formats: To see a list of supported pixel formats, codecs, and frame sizes for your connected devices, use the -list_formats option [1][2]: ffmpeg -f avfoundation -list_formats 1 -i "" 2. Specify pixel format: Use the -pixel_format option to request a specific format [1][3]. If the format you specify is not supported by the device, FFmpeg will typically provide a list of available formats and default to the first one in that list [1][4]. Example of recording with a specified pixel format: ffmpeg -f avfoundation -pixel_format bgr0 -i "default:none" out.avi In the context of the native Apple AVFoundation framework (used by developers in Swift or Objective-C), pixel formats are typically managed via AVCaptureDevice's activeFormat property or by querying the formats array. The available pixel formats for a given AVCaptureDevice are defined by the kCVPixelBufferPixelFormatTypeKey within the formatDescription of each AVCaptureDevice.Format object. The "default" format is determined by the system based on the capture session's configuration.

🌐 Web query:
site:ffmpeg.org/ffmpeg-filters.html scale in_range full tv range conversion
💡 Result:
The provided documentation for the FFmpeg scale filter does not explicitly detail an in_range or out_range parameter for manual color range conversion within the filter options [1][2]. The documentation focuses on general filter graph structure and scaling operations rather than specific color range conversion syntax [1][2]. Because the search results do not contain information regarding an in_range parameter for the scale filter, I cannot provide instructions for its use.
Citations:
Use an input-specific range conversion for AVFoundation.
commonOutputArgs applies in_range=full to avfoundation, but that input does not set -pixel_format. FFmpeg can select a device-supported YUV format. If that format uses video range, the filter can alter black and highlight levels. Inspect the negotiated format and range, then select the conversion per input or force a known format.
