stream setup during the last frame read.
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. Additional output handle, used when input and output are done separately, eg for HTTP tunneling. RTSP transport mode, such as plain or tunneled.

| int64_t RTSPState::seek_timestamp |

This value is subsequently used as part of the "Range" parameter when emitting the RTSP PLAY command. If we are currently playing, this command is called instantly. If we are currently paused, this command is called whenever we resume playback. Either way, the value is only used once, see rtsp_read_play() and rtsp_read_seek().

Basically this isn't more than a simple cache of the last PLAY/PAUSE command sent to the server, to make sure we don't send 2x the same unexpectedly or commands in the wrong state.
