If not, frames can still arrive to the sink and accumulate.
The frames past recording time will be ignored in do_*_out.

Misaligned row artifacts showed up when a 624x352 frame was converted
to BGR24 format.  When advancing to the next row the destination linesize
was added to the last output pointer position which was not linesize aligned,
resulting in a distorted picture.

Input on/off state can change in request_samples(), which can result in
a state where only the first input is active. get_available_samples()
will then return 0, and request_frame() will fail with EAGAIN even
though there is data on the single active input.

Take this into account and check the number of active inputs again after
calling request_samples().

0 should only be returned when there was at least one output frame.

start time is already substracted from the frame timestamp, so it needs
to be checked against 0, not start time.
