Methods, systems, and computer programs are presented for managing audio files of a user to reduce latencies in play start times on local devices. The audio files are stored on cloud storage managed by a server. One method includes processing a plurality of audio files associated with a user, where the processing is configured to create audio snippet files from each of the plurality of audio files. The audio snippet files representing a beginning part of each of the plurality of audio files. The method also includes transmitting the audio snippet files to a client device and detecting a request from the client to begin playing a first audio file from the plurality of audio files of the user. The first audio file being stored on the cloud storage managed by the server.

A buffer allocation method, a data processing method, an electronic device, a client and a storage media are disclosed in the present disclosure. The data processing method include receiving a writing request of an application program, the writing request including data to be buffered and a buffer object identifier, and the buffer object identifier corresponding to a buffer object; if the data to be buffered is media data, performing designated processing on the media data to cause the media data to possess a designated effect when being displayed; and writing the media data that has gone through the designated processing into a storage region pointed by the buffer object so that media data that is used is the media data that has gone through the designated processing when the buffer object is called. The present disclosure can reduce the time and the cost required in the development of application programs.

The present invention discloses a synchronized audio playing method, apparatus, and system for playing audio synchronously. By outputting designated data using a designated data buffer area before arrival of the starting time point of synchronous playing so as to make an audio link in a stable state, the method shuns from the impact of factors like system process scheduling interruption and system hardware on synchronous playing, thereby enhancing the precision of synchronous playing; moreover, upon arrival of the starting time point of synchronous playing, by computing a tuning amount of the audio data in the local synchronization buffer area, adjusting the audio data in the local synchronization buffer area according to the tuning amount, and meanwhile performing output playing on the tuned audio data, the method achieves audio synchronization play. Compared with the prior art, the present invention needn't add playing timestamp information to an audio data stream, and the playing terminal needn't process timestamp information during the entire playing procedure, thereby effectively increasing the flexibility of synchronous playing.

The present disclosure relates to methods and systems for providing virtual reality video content. An example system may include a display and a sensor configured to detect a user input and a media server configured to execute instructions stored in memory so as to carry out operations. Operations include loading a nonlinear video structure. The nonlinear video structure includes a plurality of uniform resource identifiers. Each uniform resource identifier is associated with a respective video trunk. The nonlinear video structure includes an arrangement of respective video trunks coupled by at least one transition trunk. The operations include determining an initial playlist based on the nonlinear video structure, streaming the initial playlist from a media server via network, and rendering video frames to a display. The operations include, while loading the at least one transition trunk, receiving the user input and playing a next playlist based on the received user input.

A video processing system has a storage device, an audio/video demultiplexing circuit, and a video decoder. The storage device has a bitstream buffer that is a ring buffer. The audio/video demultiplexing circuit receives an input data, and performs an audio/video demultiplexing operation upon the input data to write data of a video bitstream into the ring buffer. The video decoder fetches data of the video bitstream from the ring buffer, and performs a video decoding operation upon the fetched data of the video bitstream.
