GNOME Shell Fixes VA-API H.264 Screencasting Efficiency Issue
A fix for GNOME Shell's screencasting service was merged today, April 20, 2026, addressing a significant file size discrepancy. Previously, H.264 recordings utilizing the Video Acceleration API (VA-API) were reported to be approximately 18 times larger than recordings made with the VP8 software fallback. This patch resolves the issue, ensuring that H.264 screencasts produced via hardware acceleration will now yield file sizes comparable to or smaller than those generated using the VP8 software encoder, as expected. The fix improves the practical utility of hardware-accelerated video recording within GNOME.
