Worked on the FFmpeg/FFmpeg repository to deliver a targeted stability improvement for live RTP streaming workflows. Addressed a bug in the handling of the AVFMTCTX_UNSEEKABLE flag by correcting the duration calculation for live streams and conditionally enabling the flag based on stream characteristics. This C programming effort enhanced compatibility with external applications, such as Qt Multimedia, that depend on accurate flag handling for proper interoperability. Leveraging expertise in multimedia frameworks and network protocols, the update reduced discrepancies in duration reporting for live streams, reinforcing the reliability and integration of FFmpeg with diverse live-streaming and playback environments.
