[0058] The first embodiment of the present invention describes a streaming media data transmission method, figure 1 It is a flow chart of a streaming media data transmission method according to an embodiment of the present invention, such as figure 1 shown, the process can include:

[0059] Step 101: Package generates at least one streaming media data file containing one or more file fragments, each file fragment includes one or more chunk sub-segments, and each chunk sub-segment is a file that can be played independently;

[0060] In practical applications, the streaming media content provider may send the streaming media data file to be transmitted to the Package; here, the streaming media data file to be transmitted may include at least one of audio data and video data.

[0061] Exemplarily, when the streaming media data file to be transmitted includes audio data and video data, Package can separate the audio data and video data in the streaming media data file; generate a...

no. 2 example

[0100] The streaming media data transmission method proposed in the foregoing embodiments of the present invention will be further exemplified.

[0101] The second embodiment of the present invention mainly describes the transmission of file segments including chunk sub-segments based on a transport stream (Transport Stream, TS), which will be exemplarily described below.

[0102] After the Package is started, it can receive the incoming TS code stream of the encoder. Here, the incoming TS code stream is the streaming media data file to be transmitted as described above; the Package parses the TS code stream according to the TS specification, and converts the TS code stream from the TS stream. The audio data and the video data are separated, and then the audio data and the video data are decoded separately.

[0103] In the Package, the video processing thread can re-encode the decoded video image according to the new bit rate and resolution, generate the encoded data into a fi...

[0107] The streaming media data transmission method proposed in the foregoing embodiments of the present invention will be further exemplified.

[0108] The third embodiment of the present invention mainly describes the transmission of a file fragment including chunk sub-segments based on a Real-time Transport Protocol (RTP) stream, which will be exemplarily described below.

[0109] After the Package is started, it can receive the incoming RTP code stream of the encoder. Here, the incoming RTP code stream is the streaming media data file to be transmitted as described above; the incoming RTP code stream includes audio data and video data, and the Package is receiving After arriving at the incoming RTP code stream, according to the RTP protocol, the RTP code stream is parsed to obtain audio data and video data, and then the audio data and video data are decoded respectively.

[0110] In Package, the video processing thread can re-encode the decoded video image according to the...

Abstract

The embodiment of the invention provides a streaming media data transmission method, equipment and device, and a computer storage medium. The method is applied to a Package, and comprises the following steps: generating at least one streaming media data file containing file fragments of chunk sub-fragments, wherein each file fragment comprises one or more chunk sub-fragments, and each chunk sub-fragment is a file capable of being played independently; when a request for obtaining the chunk sub-fragments from a content delivery network CDN edge node is received, sending the corresponding chunksub-fragments to the CDN edge node according to the request for obtaining the chunk sub-fragments.

Description

technical field [0001] The embodiments of the present invention relate to, but are not limited to, media data transmission technologies, and in particular, relate to a streaming media data transmission method, device, apparatus, and computer storage medium. Background technique [0002] OTT (Over-The-Top) live broadcast refers to the live broadcast service based on the Internet. In the related OTT live broadcast technology, after the streaming media data is obtained from the streaming media content provider, file segments can be generated based on the streaming media data. Then, it is distributed through the Content Delivery Network (CDN) network, and then the terminal is provided with file fragments; after receiving any file fragment, the terminal can play the file fragment; in the technical solution of the above OTT live broadcast , the live broadcast delay of media file playback on the terminal is closely related to the duration of the file fragmentation; in order to shor...
