Abstract

A streaming media file processing method and a live streaming system are provided. The method includes slicing a streaming media file into slices according to a preset time unit; creating a playing sequence number for each slice based on time data, where the playing sequence number is used to determine an order of playing back the slices; and storing the slices and the playing sequence numbers of the slices separately and establishing a mapping relationship between the slices and the corresponding playing sequence numbers. The present disclosure slices the streaming media file based on the preset time unit, and creates the playing sequence number for each slice based on time data, and selects and processes the slice file corresponding to the playing sequence number based on the time information, which facilities the subsequent operation to the slice file. In addition, the present disclosure also provides a live streaming system.

Claims17

Dependent claims

A streaming media file processing method, comprising:

slicing a streaming media file into slices according to a preset time unit;
creating a playing sequence number for each slice based on time data, wherein the playing sequence number is configured to determine an order of playing the slices, and the time data includes a streaming timestamp of a first frame in the slice;
storing the slices and the playing sequence numbers of the slices into two separate sections of a storage module;
and establishing a mapping relationship between the slices and the corresponding playing sequence numbers, wherein creating a playing sequence number for the slice comprises:
determining a time difference between a streaming timestamp of a first frame of a current slice and a streaming timestamp of a last frame of a preceding slice;
in response to determining that the time difference is not within a range, determining that loss of data has occurred and a calibration is required for a currently created playing sequence number;
when it is determined that a calibration is required, creating the playing sequence number for the current slice according to a current system time and one frame duration;
and when it is determined that no calibration is required, applying the time data into a predetermined function to calculate the playing sequence number based on the current system time and the streaming timestamp of the first frame in the slice.

5 more elements

A live streaming system, comprising a push-stream terminal, a server, and a player, wherein:

the push-stream terminal is configured to transfer a streaming media file to the server;
a file processing module of the server is configured to:
receive the streaming media file, slice the received streaming media file into slices according to a present time unit, create a playing sequence number for each slice based on time data, wherein the playing sequence number is configured to determine an order of playing the slices, and the time data includes a streaming timestamp of a first frame in the slice, establish mapping relationship between the slices and the corresponding playing sequence numbers, and respectively send the slices, the playing sequence numbers of the slices, and the mapping relationship to a storage module of the server;
the storage module of the server is configured to:
store the slices in a first section, and the playing sequence numbers of the slices and the mapping relationship in a second section;
and the player is configured to:
obtain and select the playing sequence number from the second section, and download and play a slice from the first section based on the playing sequence number and the mapping relationship, wherein the file processing module of the server is further configured to:
determine a time difference between a streaming timestamp of a first frame of a current slice and a streaming timestamp of a last frame of a preceding slice;
in response to determining that the time difference is not within a range, determine that loss of data has occurred and a calibration is required for a currently created playing sequence number;
when it is determined that a calibration is required, create the playing sequence number for the current slice according to a current system time and one frame duration;
and when it is determined that no calibration is required, apply the time data into a predetermined function to calculate the playing sequence number based on the current system time and the streaming timestamp of the first frame in the slice.
