I've got this working in a branch that isn't upstream. This includes a BSF which deals with the pts_adjust field. It should do what you need (although the branch point is a bit stale): https://github.com/LTNGlobal-opensource/FFmpeg-ltn/commits/n4.3.1-scte35 If you're comfortable recompiling from source, you can incorporate a variant of these patches into your local tree.
