Is it possible to remux an mp4 file from a certain key frame?

Testing environment:

  • Windows 11 23H2 64 bit
  • GStreamer 1.24.8 msvc x86_64
  • NVIDIA RTX 3060 Laptop (522.06, 31.0.15.2226)

The video file is generated with nvh264enc / mfaacenc / mp4mux with default settings.

I saw a similar issue here:
