What should I do if uniapp Apple cannot play videos?

Recently, have you encountered problems playing videos using iOS applications developed by uniapp? If so, you need to read this article carefully.

uniapp is an open source cross-platform application development framework based on the Vue.js framework. It can quickly develop applications that support multiple platforms, including iOS and Android. However, some app developers found that when embedding videos in their apps, the videos could not be played on iOS devices. So how to solve this problem?

First of all, we need to understand the video tag of uniapp. This tag uses native video controls. Therefore, a device that natively supports video playback is required for normal playback. On iOS devices, only videos that support the HLS (HTTP Live Streaming) protocol can be played. For videos that do not support the HLS protocol, uniapp will use native controls to play by default.

Next, we need to check whether the HLS protocol is used in the code to play the video. The HLS protocol is a protocol developed by Apple to support video playback on iOS devices. If your video uses this protocol but still won't play, the problem may be the following.

1. Video access address problem. Many developers use local videos for testing during development, but after the application is released, the video storage location changes. At this time, you need to ensure that the access address of the video is correct and can be accessed through the public network.

2. Video encoding format problem. Unified use of H.264 encoding format videos can improve the success rate of video playback on iOS devices.

3. Video size problem. Compared with Android devices, the screen size of iOS devices is smaller, so the video file size should be appropriately reduced to improve the playback success rate.

In addition to the above problems, there may be other problems. Before solving these problems, you can refer to the official uniapp documentation or exchange experiences with the developer community.

Finally, developers should be reminded to pay attention to timeliness. We should always pay attention to the updates of iOS and uniapp framework, and adapt to new development versions in a timely manner to ensure the quality and user experience of the application.
