However, I've been using Avidemux to edit HEVC (H.265) sources and ran into the "non-IDR recovery points" warning when cutting at what the keyframe navigation buttons identified as a keyframe. As I understand it, HEVC allows CRA/recovery-point frames that look like keyframes but aren't true IDR frames, and Avidemux's next/previous-keyframe navigation doesn't currently distinguish between the two — so it's easy to land on a non-IDR point without realizing it, risking corrupted frame reordering in copy-mode cuts.
It would be a great addition to have an option (even a toggle) for keyframe navigation to jump specifically to true IDR frames for HEVC sources, rather than any I-frame-type frame. This would make it much easier to choose safe, reliably cuttable points without needing to cross-reference external tools first.
Thanks for all the work on Avidemux — it's been a genuinely useful tool for years. Avidemux rules!
