In Android, I created a layout with three surface view side by side, and I want to play one video file with different media player simultaneously. But one problem I faced that none of three can play that video simultaneously. One or two of them getting stopped the display. If I used video view instead of Media Player class directly, but the problem remains the same. Please anybody can help. What the problem is for? It is giving error surface creation failed native error. I tried different combination such as one file in 3 different view, three files in three different view, but the problem is not fixed yet. Some replies in other web site says that it depends on kernel version. If it depends on Kernel version, please can you give me any android documentation link on android site that it depends on kernel version. Or it is possible to play, please give me the steps of code. This is error log -

首先用 USB 连接你的三星 Galaxy s-II 并输入命令提示符来安装你的系统 -
At first connect your Samsung Galaxy s-II with usb and type in command prompt to mount your system -
cmd:> adb remount
然后替换文件并重新启动您的设备 -
and then replace the file and reboot your device -
cmd:> adb shell
#reboot
我注意到默认情况下，此设备使用 opencore 框架而不是 libstagefright.并且opencore有一些问题，这就是抛出中殿错误的原因.但是 libstagefright 已经在 android 2.3 版本中实现了.看看 build.prop 文件，stagefright 是禁用的.它是启用 libstagefright 框架并支持 libstagefright 框架的最佳解决方案.您也可以播放 MPEG-2TS 文件，它支持同时播放多个视频文件，没有任何问题.尝试并享受.
I've noticed that by default this device uses opencore framework instead of libstagefright. And opencore has some problem, that's why the nave error is throwing. But libstagefright is already implemented in android version 2.3. Have a look at the build.prop file, the stagefright is disable. It is the best solution to enable to libstagefright framework and do support libstagefright framework. You can play MPEG-2TS file also and it supports to play multiple video file simultaneously without having any problem. Try it and enjoy.
