avformat/rtpdec_rfc4175: Fix incorrect copy_offset calculation
The previous calculation code did not account for the fact that the copy_offset for the start of the frame array is at index 0, yet the scan line number from the rfc4175 RTP header starts at 1. This caused 2 issues to appear: - The first scan line was being copied into the array where the second scan line should be. This caused the resulting video to have a green line at the top of it. - Since the packet containing the last scan line would fail the calculation, the packet with the RTP marker would not be processed which caused a log message saying "Missed previous RTP marker" to be outputted for each frame.
