typedef struct RTSPMessageHeader RTSPMessageHeader |
This describes the server response to each RTSP command.
Private data for the RTSP demuxer.
typedef struct RTSPStream RTSPStream |
Describes a single stream, as identified by a single m= line block in the SDP content.
In the case of RDT, one RTSPStream can represent multiple AVStreams. In this case, each AVStream in this set has similar content (but different codec/bitrate).
typedef struct RTSPTransportField RTSPTransportField |
This describes a single item in the "Transport:" line of one stream as negotiated by the SETUP RTSP command.
Multiple transports are comma- separated ("Transport: x-read-rdt/tcp;interleaved=0-1,rtp/avp/udp; client_port=1000-1001;server_port=1800-1801") and described in separate RTSPTransportFields.
enum RTSPClientState |
Client state, i.e.
whether we are currently receiving data (PLAYING) or setup-but-not-receiving (PAUSED). State can be changed in applications by calling av_read_play/pause().
enum RTSPLowerTransport |
enum RTSPServerType |

void ff_rtsp_close_streams | ( | AVFormatContext * | s | ) |
Close and free all streams within the RTSP (de)muxer.

This can be used for both muxers and demuxers.

reply | pointer where the RTSP message header will be stored | |

return_on_interleaved_data | whether the function may return if we encounter a data marker ('$'), which precedes data packets over interleaved TCP/RTSP connections. If this is set, this function will return 1 after encountering a '$'. If it is not set, the function will skip any data packets (if they are encountered), until a reply has been fully parsed. If no more data is available without parsing a reply, it will return an error. |
