Oct 1, 2025Month: 2025-10 summary focusing on stability and reliability improvements in obs-studio. Implemented Removed Media Source Validation to ensure the application does not process or reference audio/video sources that have been removed, thereby preventing errors and undefined behavior during live sessions and playback. This change reduces crash surfaces and improves user experience for broadcasters who frequently modify their media sources. The work aligns with our commitment to robust source handling and maintainability in the libobs core.

Mar 1, 2025March 2025 (obsproject/obs-studio) - Focused on reliability and user experience improvements by fixing a critical scene duplication bug. Delivered a fix that preserves custom size, dimensions (cx, cy), absolute coordinates, and the last recorded width/height when duplicating a scene, ensuring consistent visuals and positioning across duplicates. This reduces manual adjustments for streamers and templates, and strengthens overall studio stability.

Nov 1, 2024November 2024 monthly summary for obsproject/obs-studio: Delivered a focused bug fix to the stinger transition path to resolve an update-count display issue during transitions. By ensuring media and matte sources are removed and re-added as active children during the transition, the patch prevents timing/display glitches and improves transition reliability for live streams. The fix, committed as 033c740d139c208b2ed4c8657f9c1125ab4c01bc, enhances user experience with more consistent transitions and reduces post-release feedback related to stinger counts.
