The encoder may keep a reference to frames that were sent to it, so the

This is going to make a copy of the existing frame data, only for the
code below to completely replace it. It will also make copies (not
references) of side data, if any.
Maybe instead unref it, set nb_samples, format and channel_layout again,
then call av_frame_get_buffer() (Factoring the existing relevant code
into its own function).
LGTM either way.
