    avformat/whip: fix ssrc might be same
    
    use audio_ssrc + 1 for video_ssrc to avoid ssrc collision
    
    See RFC 3550 Section 8,
    The SSRC identifier carried in the RTP header and in various fields
    of RTCP packets is a random 32 bit number that is required to be
    globally unique within an RTP session.
    
    simply + 1 also can get an unique ssrc, and faster than generating
    new unique ssrc.
