What should I do if the local packaged video in uniapp cannot be played?

Technological development has brought many convenient and entertainment tools and equipment, and the combination of the Internet and mobile phones has enriched information acquisition and entertainment effects. Among them, mobile applications are commonly used tools for people to obtain information and entertainment, and uniapp is a cross-platform application development framework that supports application development for multiple platforms. However, when using uniapp to package local videos, you will encounter The video cannot be played, what's going on?

uniapp is an H5 application development framework based on the Vue.js framework. It can develop multi-platform applications using HTML5, CSS3, JavaScript and other technologies. Therefore, adding local videos in uniapp is a very easy thing. To add a local video in uniapp, you only need to place the video file in the static folder in the project root directory, and then use the video tag on the page to introduce the video. However, after packaging the uniapp application into an APP, some users reported that the video could not be played. This is because there are some pitfalls in uniapp that need to be paid attention to.

First, you need to confirm whether the video file exists in the static folder. This is because some developers who add videos add video files to the assets folder of the project, causing the video to fail to be compiled when packaged. Therefore, it can be played smoothly during local development and testing but cannot be used after packaging.

Secondly, uniapp will compress and obfuscate all static resources after packaging, which will cause the video files to not play properly. Because the video file itself is a compressed binary stream file, if it is compressed and obfuscated again, the browser will not be able to parse the video file and will not be able to play it normally.

The solution is also relatively simple. You only need to process the video files separately when packaging. You can place the video files in any folder under the root directory, and then use relative paths to reference them in uniapp. . In this way, the video files will be excluded from the compression and obfuscation processing range, and the original state of the video files can be guaranteed. In addition, you can also set the playsinline and webkit-playsinline attributes in the video tag so that the video can still play normally when it is not full screen.

In short, adding local video is a very practical feature when using uniapp for application development. However, if it can be played normally during local testing but cannot be used after packaging, then you need to confirm whether the video files are placed in the correct location and turn off compression and obfuscation of the video files. Through the above adjustments, I believe that everyone will not encounter the problem that the video cannot be played when using uniapp to add local videos.
