Comment (by John Pilkington <J.Pilk@…>):
I think this is relevant here, although it refers to files that have been
cut and reformatted to MPEG2-PS by my mythDVBcut script, which uses
Project-X, mplex and mythcommflag --rebuild.
I believe that in these files, scene changes occur at keyframes. That
isn't what the editor displays. In v0.27-56-g29eab51 of 23 Oct, viewing a
processed recording (UK, DVB-T, SD, originally MPEG2-TS)
Last old-scene frame number n
First new-scene frame number n+1
Project-X vframe cut-in number n+2
Keyframe number identified by editor n+3
I see this consistently.
If stepping backwards by single frames in the editor, frames n+1 and n+2
sometimes appear interchanged. Not a problem; just a feature.
