Description
Technical Field
The present invention relates to the field of terminal technologies, and in particular, to a video buffering control method, a terminal, and a storage device.
Background
In the past, when people watch videos through a mobile terminal, the whole video file is generally downloaded and stored in the mobile terminal, and then the videos are watched. However, as the popularity and speed of mobile networks have increased, online viewing of videos has become a trend. In order to ensure the fluency of online video playing, a buffering technology is usually adopted, and a situation that playing is frozen when a video is watched is avoided by buffering certain stream data.
The inventor of the present application found in long-term research and development that the probability that the user abandons playing halfway when watching a video online is high, which results in the waste of data that is not played in the buffer. Bandwidth resources are at a premium in wireless networks, and this data waste will increase the load on the network ecosystem, and will also increase the traffic cost of the user and the power consumption of the terminal, which is not favorable for maintaining the endurance of the terminal.
Disclosure of Invention
The invention mainly solves the technical problem of providing a video buffer control method, a terminal and a storage device, which can solve the problem of data flow and bandwidth resource waste caused by giving up playing midway when a user watches videos on line.
In order to solve the above technical problem, one technical solution adopted by the present invention is to provide a video buffering control method, including:
playing a video and monitoring the buffering time of the video;
judging whether the buffering time of the video exceeds a first threshold value;
and if so, reducing the downloading speed of the video.
In order to solve the above technical problem, another technical solution adopted by the present invention is to provide a terminal for controlling video buffering, comprising a display screen and a processor coupled to each other;
the processor is used for controlling the display screen to play videos, monitoring the buffering time of the videos and judging whether the buffering time of the videos exceeds a first threshold value or not;
the processor is further configured to reduce a download speed of the video when a buffering time of the video exceeds a first threshold.
In order to solve the above technical problem, another technical solution of the present invention is to provide a storage device storing program data, which can be executed to implement the above method.
According to the invention, by monitoring the buffering time of the video, the downloading speed of the video is reduced when the buffering time of the video exceeds the first threshold, the current playing of the video can be ensured to be smooth when the buffering time reaches the first threshold, and meanwhile, the data flow and bandwidth resources required by video buffering can be reduced by reducing the downloading speed of the video, so that even if a user abandons playing the video, the wasted data flow and bandwidth resources can be correspondingly reduced.

optionally, the second threshold may be a default second threshold, or may be set by a user. For example, the second threshold may be 15 minutes, 30 minutes, etc.
S105, if yes, playing the video and monitoring the buffering time of the video, otherwise, normally buffering the video;
in this embodiment, the buffering time is counted from the time when the video is turned on as the starting point of the counting. The buffering time can be judged by monitoring the time display of the video software, and can also be timed by the timing software of the terminal.
S106, judging whether the buffering time of the video exceeds a first threshold value;
optionally, the first threshold may be a default first threshold, or may be set by a user. For example, the first threshold may be 5 minutes, 10 minutes, etc.
S107, if yes, reducing the downloading speed of the video, otherwise, normally buffering the video;
the optional reduced download speed may be a default download speed, may also be a download speed preset by the user, and may also be adjusted according to the download speed of the normal buffer. For example, the reduced download speed is set to be 100kB/s (kilobyte/s) and 200kB/s, or the download speed of the normal buffer is set to be 600kB/s, and the reduced download speed is half of the download speed of the normal buffer (300kB/s) or 1/3(200kB/s), and so on.
