## Link to GitHub Issue or related Pull Request, if one exists #201 ## Description of change - Adds MJPEG camera support using Media Foundation decoding. - Moves camera capture to asynchronous Source Reader callbacks. - Supports native NV12 and YUY2 capture, preferring target-sized native formats over MJPEG when possible. - Improves capture and rendering performance through callback-paced reads, bulk frame uploads, optimized row-based flips, and lazy allocation of flip textures. - Makes runtime media-type changes interrupt pending reads and safely flush and reconfigure the Source Reader. - Improves automatic mode selection based on aspect ratio, proximity to 1280x720, frame rate, and capture format. - Hardens camera shutdown, flush handling, media-type changes, and repeated capture failures. ## Testing Tested with two cameras in tdj
