Abstract
A method and apparatus for optimizing a video playback start, a device and a storage medium are provided. An implementation of the method may include: acquiring feature data, the acquired feature data affecting the video playback start speed when a video starts to play; inputting the acquired feature data into a pre-trained gradient boosting decision tree (GBDT) regression model to output a predicted value for a video buffer frame, and recording the predicted value as a first predicted value; and ascertaining whether to start playing the video based on the first predicted value.
Claims20
A method for optimizing a video playback start, comprising:
- acquiring feature data, the acquired feature data affecting the video playback start speed when a video starts to play;
- inputting the acquired feature data into a gradient boosting decision tree (GBDT) regression model to output a predicted value for a minimum number of video buffer frames, and recording the predicted value as a first predicted value;
- and
- comparing a number of video frames actually buffered by a player with the first predicted value;
- and
- playing the video by the player, in response to the number of the video frames actually buffered by the player being greater than the first predicted value.
An electronic device, comprising:
- at least one processor;
- and
- a storage device, communicated with the at least one processor,
- wherein the storage device stores an instruction executable by the at least one processor, and the instruction is executed by the at least one processor, to enable the at least one processor to perform operations, the operations comprising:
- acquiring feature data, the acquired feature data affecting the video playback start speed when a video starts to play;
- inputting the acquired feature data into a gradient boosting decision tree (GBDT) regression model to output a predicted value for a minimum number of video buffer frames, and recording the predicted value as a first predicted value;
- and
- comparing a number of video frames actually buffered by a player with the first predicted value;
- and
- playing the video by the player, in response to the number of the video frames actually buffered by the player being greater than the first predicted value.
A non-transitory computer readable storage medium, storing a computer instruction, wherein the computer instruction, when executed by a processor, causes the processor to perform operations, the operations comprising:
- acquiring feature data, the acquired feature data affecting the video playback start speed when a video starts to play;
- inputting the acquired feature data into a gradient boosting decision tree (GBDT) regression model to output a predicted value for a minimum number of video buffer frames, and recording the predicted value as a first predicted value;
- and
- comparing a number of video frames actually buffered by a player with the first predicted value;
- and
- playing the video by the player, in response to the number of the video frames actually buffered by the player being greater than the first predicted value.
