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

[0032] The invention can conveniently and accurately restore the RTP data packet into the media track and streaming track data in the ISO media file, and supports playing through the streaming server. ISO media files include but are not limited to: base media file format defined in ISO14496-12, MP4 file format defined by ISO14496-14, AVC file format defined by ISO14496-15, 3GPP file format defined by 3GPP TS26.244, 3GPP2C.S0050 -0 defines the 3GPP2 file format.

[0033] 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 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 number and interval.

[0034] The preferred embodiments of the present invention will be de...

Abstract

The invention discloses a method for processing an ISO media document according to a RTP packet of a streaming media technology, which comprises the following steps: boundary of a fluidization sample is determined; sampling data of a virtual media sample is generated; serial numbers of the virtual media sample is determined; data of the fluidization sample is generated; a media document is generated according to the format of the ISO media document; the generated media document is read by a streaming media server. Compared with the prior art, the method simplifies the processing flow so that the specific coding format can be unconcerned. The load data of an original RTP is basically preserved which can reappear truly the original RTP data. Besides, the method has a good expansibility and a good compatibility for coding format 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 in the streaming media technology. Background technique [0002] In fixed network streaming media and mobile streaming media, the streaming media server needs to transfer the RTP data packets from the live encoder to a standard ISO media file format according to a certain strategy and release it 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 practice is: for a specific encoding format, according to the definition of the streaming standard, parse the streaming information in the RTP payload data, restore the real media sample, and then generate the corresponding streaming sample data. RTP payload data consists of streaming information and sampling data. The streaming information does not belong to...
