我有一个视频字节数组格式,我如何在android 2.2中的surfaceViewer上绘制？一世
我正在尝试视频聊天.我使用onPreviewFrame,我有一个字节[]我将发送到服务器,而不是服务器发送到其他客户端,而另一个客户端将有一个字节[],我的问题是：我怎么画这个(字节[ ])在客户端？
最佳答案
这里是你的应用程序的所有代码,我的意思是这里是你的视频聊天或部分:),我没有在Android 2.2上尝试我的代码,但它适用于Android 2.3.3,它的工作原理是这样的,你设置一些在editText中设备本地IP地址,然后你必须按下聊天视频按钮,所以其他部分,你设置的IP地址,将看到你的前置摄像头的视频

List这是xml
尝试它;),不要忘记upvote :),也不要忘记在manifest.xml中添加这些行
