This is used to detect if we need to subscribe or unsubscribe to any new streams. current stream setup. This is a temporary buffer used to compare current setup to previous frame setup. the last value of the "SET_PARAMETER Subscribe:" RTSP command. this is used to send the same "Unsubscribe:" if stream setup changed, before sending a new "Subscribe:" command. The following are used for RTP/ASF streams ASF demuxer context for the embedded ASF stream from WMS servers cache for position of the asf demuxer, since we load a new data packet in the bytecontext for each incoming RTSP packet. some MS RTSP streams contain a URL in the SDP that we need to use for all subsequent RTSP requests, rather than the input URI; in other cases, this is a copy of AVFormatContext->filename.
