During March 2026, crimsonspecter enhanced the jellyfin/jellyfin repository by refining HLS segment length calculations for remuxed content, directly addressing playback issues caused by fractional framerates in transcoded videos. This work involved precise timing math and adjustments to backend logic, resulting in smoother and more reliable HLS media streaming. Using C# and leveraging expertise in API and backend development, crimsonspecter backported and integrated changes from the release-10.11.z branch to maintain compatibility with the 10.11.x line. The updates improved playback stability and reduced timing glitches, demonstrating a focused and technically detailed approach to media streaming reliability.
