<p>Disclosed are a video recording method and system, which enable complete transmission of an SDP, and ensure that a decoder can perform decoding correctly, thus realizing nondestructive rapid processing of video information. The method comprises: acquiring a client SDP, and checking whether the SDP contains an SPPS; if yes, directly performing decoding and recording processing on a data packet acquired from the client; and if no, acquiring a media packet from the client, writing an SPPS acquired from the media packet into the SDP, and then performing decoding and recording processing on the data packet acquired from the client. The recording system comprises: a forwarding module, a recording module and a signalling processing module.</p> |
