Nov 1, 2024November 2024 performance snapshot for obsproject/obs-studio: Delivered Linux-specific enhancements and memory reporting fixes that improve broadcast fidelity and system visibility. Implemented Linux memory reporting fix to os_get_free_size() using sysinfo() and including buffer RAM, eliminating zero-memory reports. Enhanced Linux broadcasting by collecting detailed hardware/system information (CPU, GPU, OS) via libpci and system files, formatting data for GetClientConfiguration to enable richer client broadcasts. These changes improve monitoring accuracy, enable deeper client-side customization, and contribute to more reliable streaming experiences. Key commits include 935613816fd8ed384ba86b035bd73af025258a11 and e1d2cf705dd9e8e36f1d2360c443e6bb49dbbe0e.
