Provided are a video recording method and apparatus. The video recording method includes: in response to detecting a resume recording instruction, determining duration of a video coded by a video coder, and setting playback progress of an audio player to the duration, where the resume recording instruction is used for instructing to continue collecting video data and continue playing target audio data by using the audio player; starting the audio player, where the video coder is started before the audio player; in the case of playing the target audio data to the playback progress, in response to collecting the video data, transmitting the collected video data to the video coder so that the video coder codes the collected video data.

A device for recording videos includes an image signal processor to process frames captured in response to a request for recording a video at a first frame rate, and a video encoder to encode captured frames. The device also includes processing circuitry operative to allocate image buffers from memory in response to the request, and execute a camera software to direct the image signal processor to fill each image buffer with a batch of the captured frames. For each filled image buffer, a reference of the image buffer is passed from the camera software to a video software at a second rate, which is a fraction of the first frame rate. The processing circuitry then executes the video software to provide one frame at a time to the video encoder for encoding at the first frame rate.

An image capture device for recording HDR (high dynamic range) image data obtained through image capture performs control so as to, when encoding HDR image data obtained by capturing an image with an image sensor, divide part of the HDR image data corresponding to a coding area to be encoded into a plurality of divided HDR image data, encode each of the plurality of divided HDR image data by using encoding means, and record the plurality of divided HDR image data that are encoded on a recording medium in a predetermined recording format.

In various embodiments, an iterative encoding application encodes a source video sequence. The encoding optimization application generates a set of shot encode points based on a set of encoding points and a first shot sequence included in the source video sequence. Each shot encode point is associated with a different encoded shot sequence. The encoding optimization application performs convex hull operation(s) across the set of shot encode points to generate a first convex hull associated with the first shot sequence. Subsequently, the encoding optimization application generates encoded video sequences based on the first convex hull and a second convex hull associated with a second shot sequence included in the source video sequence. The encoding optimization application computes a new encoding point based on the encoded video sequences and a target value for a first video metric and then generates an optimized encoded video sequence based on the new encoding point.

An image processing device includes a multimedia intellectual property (IP) block which processes image data including a first component and a second component; a memory; and a frame buffer compressor (FBC) which compresses the image data to generate compressed data and stores the compressed data in the memory. The frame buffer compressor includes a logic circuit which controls a compression sequence of the first component and the second component of the image data.

In various embodiments, an encoding optimization application encodes a source video sequence. The encoding optimization application partitions a source video sequence associated with a media title into multiple subsequences that include a first subsequence and a second subsequence. Subsequently, the encoding optimization application generates a first encoded subsequence based on the first subsequence and a first value of an encoding parameter. The encoding optimization application generates a second encoded subsequence based on the second subsequence and a second value for the encoding parameter. Notably, the second value of the encoding parameter is not equal to the first value of the encoding parameter. The encoding optimization application then aggregates the first encoded subsequence and the second encoded subsequence to generate an encoded video sequence. At least a portion of the encoded video sequence is subsequently streamed to an endpoint device during a playback of the media title.

This application discloses a multimedia file joining method performed by an apparatus. After obtaining a first video clip and a second video clip to be joined, the apparatus obtains an audio file corresponding to the first video clip and the second video clip. The audio file records the first start and end time points of the first video clip and the second start and end time points of the second video clip. The apparatus adjusts the first video clip to play the first video clip in a first time period indicated by the first and end time points, and adjusts the second video clip to play the second video clip in a second time period indicated by the second and end time points with the first time period not overlapping the second time period. Finally, the apparatus performs a joining operation on the adjusted first video clip and the adjusted second video clip, to obtain a joined video file.

Aspects of encoding and decoding video content are provided. An encoding system detects a scene change by identifying a first picture among a sequence of pictures that corresponds to a last picture of a first scene, identifying a second picture among the sequence of pictures that corresponds to a first picture of a second scene, and determining that one or more pictures that are between the first picture and the second picture in the sequence of pictures correspond to an input transition scene between the first scene and the second scene. The encoded video content indicates an existence of the input transition scene and information for reproducing a transition scene. A decoding system generates the transition scene that corresponds to the input transition scene based on the received indication of the existence of the input transition scene and the information for reproducing the transition scene.

A series of frames forming the moving image includes intra-frame predictive frames, inter-frame predictive frames, and a non-reference frame at predetermined intervals. A still image corresponding to a next non-reference frame is encoded when a waiting period from an instruction point in time at which a still image is instructed to be captured to the next non-reference frame is equal to or less than a predetermined time. An image of a current frame at the instruction point in time as a non-reference frame is encoded, and a still image corresponding to the current frame is encoded when the waiting period exceeds the predetermined time.
