- class mini_arcade_core.runtime.capture.video.VideoRecordConfig¶
Configuration for video recording.
- Variables:
(int) (capture_fps) – Desired output frames per second.
(int) – Actual capture frames per second to reduce stalls.
(str) (prefix) – File extension for saved frames.
(str) – Directory to save recorded frames.
(str) – Prefix for recording session directories.
- fps: int = 60¶
- capture_fps: int = 15¶
- ext: str = 'png'¶
- frames_dir: str = 'recordings'¶
- prefix: str = 'run_'¶
- class mini_arcade_core.runtime.capture.video.VideoRecorder(cfg: VideoRecordConfig | None = None)¶
Video recording management.
- cfg¶
- active: bool = False¶
- run_id: str = ''¶
- base_dir: pathlib.Path | None = None¶
- start(*, out_dir: pathlib.Path | None = None) pathlib.Path¶
Start video recording.
- Parameters:
out_dir (Path | None) – Optional output directory for recorded frames.
- Returns:
Path to the directory where video frames are saved.
- Return type:
Path
- stop() None¶
Stop video recording.
- should_capture(frame_index: int) bool¶
Check if the current frame index should be captured based on the capture frequency.
- Parameters:
frame_index (int) – The current frame index.
- Returns:
True if the frame should be captured, False otherwise.
- Return type:
bool
- next_paths() tuple[pathlib.Path, pathlib.Path, int]¶
Returns: (tmp_bmp_path, out_png_path, out_frame_index) out_frame_index increases only when we actually capture.
- Parameters:
frame_index (int) – The current frame index.
- Raise:
RuntimeError: If the recorder is not active.
