STREAM_SOURCE_SEQUENCE_TRANSITION_HARD_CUT_AT_EOF

1

Wait for the previous source to fully drain, then start emitting this source’s frames. The cross-source rebase keeps display PTSs contiguous. The default for non-first entries.

STREAM_SOURCE_SEQUENCE_TRANSITION_HARD_CUT_AT_IDR

2

Cut at this source’s next IDR (used by the manual advance_now trigger). The previous source’s frames after that IDR in display order are dropped.
