Does HarmonyOS support URL-based video playback? How to develop?

Yes, HarmonyOS supports URL playback. As a multi-device operating system, HarmonyOS provides various media playback capabilities, including video playback via network URLs. Developers can implement this functionality using HarmonyOS's media library, specifically through the MediaPlayer and VideoPlayer components.

How to develop?

Developing video URL playback functionality can be broken down into the following steps:

1. Add necessary permissions

First, add network access permissions to the application's configuration file, as network video playback requires internet access:

xml
<ohos:permission>ohos.permission.INTERNET</ohos:permission>

2. Create media playback components

Use the VideoPlayer component to play videos. Add it to your layout file:

xml
<VideoPlayer
    ohos:id="$+id:video_player"
    ohos:width="match_parent"
    ohos:height="match_parent" />

3. Set the video source in code

In your Ability (similar to Android's Activity), obtain the VideoPlayer instance and set the video URL:

java
@Override
public void onStart(Intent intent) {
    super.onStart(intent);
    super.setUIContent(ResourceTable.Layout_ability_main);

    VideoPlayer videoPlayer = (VideoPlayer) findComponentById(ResourceTable.Id_video_player);
    videoPlayer.setSource("http://example.com/video.mp4");
    videoPlayer.start();
}

4. Control video playback

Add playback, pause, and stop controls. The VideoPlayer component provides methods like start(), pause(), and stop() for this purpose.

For example, add buttons to control playback and pause:

java
Button playButton = (Button) findComponentById(ResourceTable.Id_play_button);
Button pauseButton = (Button) findComponentById(ResourceTable.Id_pause_button);

playButton.setClickedListener(listener -> videoPlayer.start());
pauseButton.setClickedListener(listener -> videoPlayer.pause());

Conclusion

By following these steps, you can implement URL-based video playback in HarmonyOS applications. The development process is similar to other platforms but leverages HarmonyOS-specific components and APIs. HarmonyOS provides developers with comprehensive documentation and tools to quickly get started and implement multi-device deployment.
