commit ae5338556102dffd2888ab400ecd8df299209c70 Author: Desmond Liu <[email protected]> AuthorDate: Mon Jan 5 13:34:24 2026 -0800 Commit: Marvin Scholz <[email protected]> CommitDate: Mon Jun 29 13:20:39 2026 +0200 fftools/ffmpeg_demux: Fix readrate sleep calculation Calculation of max_pts and limit_pts may overflow because adding (int64_t + int64_t + float) results in a float that easily overflows. This can trigger a very long av_usleep().
