要在Agora Unity SDK中实现多视频播放器,可以按照以下步骤进行:
下面是一个简单的代码示例,演示如何使用Agora Unity SDK创建一个简单的多视频播放器:
using UnityEngine;
using agora_gaming_rtc;
public class MultiVideoPlayer : MonoBehaviour
{
// Agora AppId
public string appId = "YOUR_APP_ID";
// Agora Video Surface prefab
public GameObject videoSurfacePrefab;
// Agora Video Surface objects
private GameObject[] videoSurfaces;
// Agora RTC Engine
private IRtcEngine rtcEngine;
// Number of video players
public int numPlayers = 2;
// Start is called before the first frame update
void Start()
{
// Initialize Agora RTC Engine
rtcEngine = IRtcEngine.GetEngine(appId);
// Enable video module
rtcEngine.EnableVideo();
// Create video surface objects
videoSurfaces = new GameObject[numPlayers];
for (int i = 0; i < numPlayers; i++)
{
// Instantiate video surface prefab
videoSurfaces[i] = Instantiate(videoSurfacePrefab);
// Set video surface properties
videoSurfaces[i].GetComponent().SetForUser(rtcEngine.GetUid());
videoSurfaces[i].GetComponent().SetEnable(true);
videoSurfaces[i].GetComponent().SetVideoSurfaceType(AgoraVideoSurfaceType.RawImage);
// Set video surface position and size
// ...
// Add video surface to RTC engine
rtcEngine.SetupRemoteVideo(videoSurfaces[i].GetComponent().GetRawImage(), uid, ChannelProfile.LiveBroadcasting);
}
}
// Update is called once per frame
void Update()
{
// Handle user input to create or destroy video players
// ...
}
// Clean up resources
void OnDestroy()
{
// Destroy video surface objects
foreach (var videoSurface in videoSurfaces)
{
Destroy(videoSurface);
}
// Release Agora RTC Engine
rtcEngine.LeaveChannel();
rtcEngine.Dispose();
rtcEngine = null;
}
}
在上面的示例代码中,我们首先初始化Agora RTC Engine,并启用视频模块。然后,我们使用循环创建指定数量的视频播放器对象,并设置其属性,如视频尺寸、位置等。最后,我们将每个视频播放器对象连接到Agora RTC Engine,并在Update方法中处理用户输入以创建或销毁视频播放器。在OnDestroy方法中,我们清理资源并释放Agora RTC Engine。
请注意,上述代码只是一个示例,你可以根据自己的需求进行修改和扩展。确保在使用Agora Unity SDK时阅读并遵循官方文档和API文档。
