Problems solved by technology

[0004] Since there are many encoding formats supported in the prior art, the streaming standards of each encoding are different, and the streaming method is relatively flexible, so it is cumbersome and difficult to restore the original media sample according to the RTP packet load data The problem of correctly restoring all media samples, in addition, this approach also has scalability problems

Embodiment Construction

[0033] The invention can conveniently and accurately restore the RTP data packet to the media track (media track) and streaming track (hint track) data in the ISO media file, and supports playing through the streaming server. ISO media files include but are not limited to: basic media file format defined in ISO 14496-12, MP4 file format defined in ISO14496-14, AVC file format defined in ISO14496-15, 3GPP file format defined in 3GPP TS26.244, and 3GPP2C 3GPP2 file format defined by .S0050-0.

[0034] The core of the technical solution of the present invention is to virtualize all RTP load data (including streaming information and sampling data) included in a streaming sample into a media sample, and all the entry data of the streaming sample point to the same virtual media sample data. The virtual media samples generated by this method are in one-to-one correspondence with the streaming samples, and have the same sample sequence number and interval.

Abstract

The present invention discloses a method of generating ISO media files according to RTP packet, having the following steps of determining the boundary of a fluidized sample, generating sampled data of a virtual media sample, determining the sequence number of the virtual media sample and generating the data of the fluidized sample. The present invention further comprises the steps of generating amedia file according to the regulation of ISO media file format and reading the generated media file through a streaming media server. The present invention also discloses a method of reading generated media files through a streaming media server. Compared with the prior art, the present invention simplifies processing flow, can pay no attention to concrete coding format, basically preserves the prior RTP load data, and can truly reproduce the prior RTP data. Moreover, the method has good expansibility, and can be easily compatible with coding formats expanded afterwards.

Description

technical field [0001] The invention relates to a streaming media technology, in particular to a method for generating ISO media files according to RTP packets. Background technique [0002] In fixed network streaming media and mobile streaming media, the streaming media server needs to transfer the RTP data packets transmitted by the live encoder according to a certain strategy into a standard ISO media file format for release for later on-demand. A very critical step in dumping media files is to restore the RTP payload data to the original media data and streaming data. [0003] The general approach is: for a specific encoding format, according to the definition of its streaming standard, analyze the streaming information in the RTP payload data, restore the real media samples, and then generate the corresponding streaming sample data. The RTP payload data consists of two parts: streaming information and sampling data. The streaming information does not belong to the med...
