Audio Overlay for a specific time

Hi @izzytwosheds ,

Is there an option to overlay audio or video for only a specific time duration? For example: if we have a video of length 40 seconds and we want to overlay audio from 5 seconds to 25 seconds only, how can it be achieved?

From looking at AudioOverlayFilter's apply method, it uses ByteBuffer but no presentationTime to make any such operation.

Any insight or guidance would be highly valuable to us.

Start by reading AudioOverlayFilter's apply method and tracing how its ByteBuffer input is processed. Determine how presentation time is represented in the surrounding audio/video pipeline, then define the behavior needed for an overlay limited to 5–25 seconds. Done means the requested time-bounded overlay behavior is supported and documented by appropriate coverage.
