Here's what Virginia's FOIA says in section 2.2-3707(H) about recording meetings:
Any person may photograph, film, record or otherwise reproduce any portion of a meeting required to be open. The public body conducting the meeting may adopt rules governing the placement and use of equipment necessary for broadcasting, photographing, filming or recording a meeting to prevent interference with the proceedings, but shall not prohibit or otherwise prevent any person from photographing, filming, recording, or otherwise reproducing any portion of a meeting required to be open.
