How to improve the video smoothness of Uniapp

With the development of mobile Internet, video has become an indispensable media form in people's daily lives. Whether it is short video, live broadcast or long video, they all need a smooth playback experience to attract more users. As an open source framework that integrates multi-terminal support and rapid development, Uniapp also has its unique advantages in playing videos. So, how to improve the video smoothness of Uniapp? Let’s discuss it below.

First, choose an efficient video encoding method

The video encoding method is one of the keys to the smoothness of the video. Common video encoding methods include H.264, VP9, ​​AV1, etc. The H.264 encoding method is a relatively mature encoding method, and this encoding method is basically supported by the market. VP9 and AV1 are relatively new encoding methods, which can provide better visual effects and compression efficiency. Of course, since these two encoding methods require higher hardware support, the hardware requirements are also higher.

When choosing a video encoding method, developers need to fully consider their own project needs and the device configuration of the target users. If the target user's device configuration is low, then H.264 encoding should be selected to ensure smooth video playback. If the target user's device configuration is higher, you can consider using VP9 or AV1 encoding to provide better visual effects.

Second, adjust the video bit rate and resolution

The bit rate and resolution are also key factors that affect the smoothness of the video. During video playback, if the bit rate and resolution are too high, the video will freeze or fail to play properly. Too low bit rate and resolution will affect the clarity and visual experience of the video. Therefore, when making videos, developers need to make reasonable adjustments for different scenarios and needs.

Specifically, if the target user's device configuration is low, then the bitrate and resolution of the video need to be adjusted to an appropriate level. Generally speaking, the bit rate can be controlled at around 1Mbps and the resolution at around 480P. If the target user has a higher device configuration, the bit rate and resolution can be adjusted to a higher level to provide better visual effects.

Third, optimize player settings

The video player is also an important factor affecting the smoothness of the video. Uniapp's built-in video player can adapt to different platforms and devices, and supports the playback of multiple video formats. However, in actual use, developers still need to further optimize according to different needs.

Specifically, you can optimize the player settings in the following ways:

1. Turn on hardware acceleration

In some cases, turning on hardware acceleration can improve the performance of video playback efficiency. In Uniapp, hardware acceleration can be turned on by setting the plus.video.HWDecoder property.

2. Choose a smooth player

Uniapp provides a variety of video players, including video, live-player and live-pusher. Among them, the video player supports multiple platforms, but its performance is not optimal. Therefore, if you need to improve the smoothness of video playback, you can consider using live-player or live-pusher player.

3. Use caching technology

Caching can reduce server pressure to a certain extent and improve the smoothness of video playback. In Uniapp, you can use the uniCache plug-in to implement video caching. It should be noted that when using caching technology, you should avoid having too many cached files that occupy too much storage space.

Summary:

Through the above three methods, Uniapp’s video playback smoothness can be effectively improved. In actual development, developers need to carry out targeted optimization based on their own project needs and the device configuration of target users. Only by ensuring fluency can we stand out in the fiercely competitive market and gain more user support.
