Embodiment 1

[0069] Such as image 3 As shown, it is a method for converting a video in a non-supporting format in a mobile terminal described in Embodiment 1 of the present invention, including:

[0070] Step 301, the mobile terminal receives the index file information corresponding to the video and converts the index file information into local index file information and saves it after sending the video request information in an unsupported format to the network server;

[0071] Step 302, the mobile terminal sends the video conversion request information of the unsupported format to the proxy server in the mobile terminal, and the proxy server performs fragmentation processing on the video, generates at least one TS file after fragmentation, and Establishing a corresponding relationship between the TS file and the local index file, and storing it in the memory queue of the mobile terminal;

[0072] Step 303, the player of the mobile terminal calls the TS file according to the local inde...

Embodiment 2

[0074] Such as Figure 4 As shown, on the basis of Embodiment 1, a method for converting a video in a non-supporting format in a mobile terminal described in this invention is characterized in that it includes:

[0075] Step 401, the mobile terminal receives the index file information corresponding to the video and converts the index file information into local index file information and saves it after sending the video request information in an unsupported format to the network server;

[0076] Step 402, the mobile terminal sends the conversion request information of the video in the non-support format to the proxy server in the mobile terminal, and the proxy server according to the request segment number in the conversion request information of the video in the non-support format ( The number of fragments requested is the number of fragments preset in the request information), and the offset of the video in the video stream is calculated, and the proxy server determines the ...

Embodiment 4

[0093] Such as Figure 6 As shown, it is a system for converting video in a non-supporting format in a mobile terminal according to the present invention, which is characterized in that the system is set in the mobile terminal, and the system includes: a receiving module 601, a processing module 602 and Play module 603; Wherein,

[0094] The receiving module 601, coupled with the processing module 602, is used to receive the index file information corresponding to the video returned after sending the video request information in an unsupported format to the network server, and convert the index file information Save the local index file information;

[0095] The processing module 602 is coupled to the receiving module 601 and the playing module 603 respectively, and is used to receive the conversion request information of the video in the non-supported format sent by the mobile terminal, perform fragment processing on the video, and generate fragments After at least one TS f...

Abstract

The application discloses a method and a system for converting a video with a non-supporting format in a mobile terminal. The method comprises the steps as follows: the mobile terminal receives corresponding index file information with the video returned after transmitting video requesting information of the non-supporting format to a network server, and converts the index file information into local index file information and stores the local index file information, and the mobile terminal transmits conversion requesting information of the video with the non-supporting format to a proxy server in the mobile terminal, and the proxy server performs segmenting process to the video and generates at least one TS file after segmenting, and establishes a corresponding relation between the TS file and a local index file, and stores in an internal storage queue of the mobile terminal; a player in the mobile terminal retrieves the TS file to play according to the local index file in the internal storage queue. The method of the invention reduces the pressure to the server while the mobile terminal plays the video with the non-supporting format and achieves the condition of locally playing the video with the non-supporting format at the mobile terminal.

Description

technical field [0001] The present application relates to the field of video playback, and in particular relates to a method and system for converting a video in a format not supported by a mobile terminal. Background technique [0002] At present, it is more and more common for mobile terminals to order videos from Internet multimedia, and commonly used videos have various formats. The video format refers to the way of organizing the video data, audio data and related information data in the video. Video data is implemented in a specific format during storage and transmission, and different video formats are implemented in different ways. The commonly used video formats at this stage mainly include TS, FLV, HLS and so on. [0003] TS (Transport Stream), the full name is MPEG2-TS, is a file packaging format captured by a high-definition camera. The TS file is sent by sub-packet, and each package is 188 bytes long. The structure of the package is: the header is 4 bytes, a...
