refactor: NDIHelper → NDIReceiver with cleaner API and naming
NDIReceiver (shared/NDIReceiver.hpp):
- Rename class NDIHelper → NDIReceiver, file NDIHelper.hpp → NDIReceiver.hpp
- Add SourceInfo struct (width, height, fps_num, fps_den, stride, fourcc)
replacing raw public member variables (xres, yres, frame_N, frame_D, stride)
- find_sources() now returns std::vector<std::string> instead of output pointer
- select_source() + get_source_info() → connect() + probe() (cleaner sequence,
probe() returns SourceInfo and stores it internally for capture_v210)
- getV210_video_frame() → capture_v210() — removes unused source_num parameter
- get_bytes_per_pixel, fourCCtoStr → private static bytes_per_pixel, fourcc_str
- u_int32_t → uint32_t; (uint32_t) casts → static_cast
- probe() checks g_running to avoid hanging if source never sends video
ndiin/main.cpp:
- Update to new NDIReceiver API
- malloc/free latest_buffer → std::vector<uint8_t> latest_frame
- Remove unused #include <Processing.NDI.Lib.h> and V210.hpp
- memcpy uses latest_frame.size() instead of separate frame_bytes variable
