Abstract: The invention is a method for live broadcast based on HLS protocol and electronic device provided, wherein a M3U8 index list is downloaded from a sub-server and a program resource slice downloaded according to the M3U8 index list is played, after a master server redistributes another sub-server, the M3U8 index list and a program resource slice are downloaded from the new distributed sub-server; the program resource slice downloaded from the new sub-server is analyzed to acquire a PTS timestamp information in the downloaded slice; and the PTS timestamp information in the slice downloaded from the new sub-server is compared with the PTS timestamp information in the slice downloaded from the original sub-server, and it is determined whether the currently downloaded program resource slice is played according to the comparison result. It provides the users with a smooth watching experience of the live broadcast video in one's terminal device.

Abstract: Embodiments of the present disclosure disclose a method and a device for audio data processing. The method comprises detecting a received audio data packet to determine a stream type of the audio data packet, obtaining tag data of the audio data packet when the stream type is a first stream type, determining whether the tag data belongs to preset Dolby tag information, determining the first stream type as the stream type corresponding to a Dolby DVB standard when the tag data belongs to the preset Dolby tag information, and decoding the audio data packet by means of a Dolby decoder to generate audio data.

Abstract: An embodiment of the present disclosure discloses a play method and device, wherein the method specifically comprises the steps of a player receiving a calling request from an application, wherein the calling request comprises the address parameter of multi-media contents and the position parameter of the multi-media contents; the player acquiring the multi-media contents starting from a target position corresponding to the position parameter from a server according to the address parameter; and the player playing the multi-media contents starting from the target position. The embodiment of the present disclosure may improve the efficiency of playing multi-media contents from the target position for the first time, and save memory space of an information device.

Abstract: Embodiments of the present disclosure disclose a method and a device for generating and playing a video, The method for generating a video comprises: collecting at least two live video streams by a server and assigning identifiers to the live video streams, respectively; integrating, the live video streams according to the identifiers to generate an integrated live video stream; assigning a resource address to the integrated live video stream; feeding back the corresponding integrated live video stream to a player after receiving a request for the resource address. A plurality of video streams can be transmitted simultaneously by means of the integrated live video stream, and thus can be played synchronously.

Abstract: An embodiment of the present disclosure discloses a method and a device for playing streaming media. The method comprises: pre-configuring a starting threshold for a player; when detecting a play command, acquiring time length information corresponding to buffer data, downloaded by the player; comparing the time length information with the starting threshold, determining status information of the player; and controlling the player to play streaming media according to the status information. Through pre-configuring the starting threshold for the player, the embodiment of the present disclosure avoids problem of low starting efficiency of the player caused by using a native threshold of Google, improving the starting efficiency and saving time for users.

Abstract: An embodiment of the present disclosure discloses a method for playing a video. The method comprises: parsing a file to be played to obtain one video stream and at least two audio streams by a player and saving the video and audio streams into a buffer; selecting a certain audio stream as a first audio stream, and obtaining the stream and the first audio stream from the buffer for decoding and playing; receiving an audio switching instruction, and determining one other channel of audio as a second audio stream according to the audio switching instruction; stopping decoding the first audio stream, and obtaining the video stream and the second audio stream from the buffer for decoding and playing. By using the method for playing a video, reparsing and readdressing are avoided; therefore, the time of addressing is saved, and the efficiency of switching is improved.

Abstract: An embodiment of the present disclosure discloses a player-based play method and a player device. The method comprises: monitoring a player and generating a seek event of the player during the process of playing streaming media; determining a target segment of the streaming media according to the seek event, and acquiring buffer data of the target segment; and playing streaming media from the buffer data of the target segment. Through skipping over to the buffer data of the target segment, the embodiment of the present disclosure directly plays streaming media starting from buffer data of the target segment, so the player does not need to seek the key frame when adjusting the play progress, avoiding the problem of time waste caused by seeking the key frame, improving the starting efficiency of the player, and saving time.
