Hi Android Developers, I meet some problems playing multiple videos at the same time on Samsung Galaxy S2. I am trying to play multiple videos at the same time in a screen. Then I initialize multiple VideoView on the same screen, and load the different videos. While only the first VideoView is being played successfully.
The device is running on Android 4.0.4 I am trying to read the source code of VideoView, I found out that the VideoView is a holder of SurfaceView + MediaPlayer. And I locate the error is caused by multiple MediaPlayer trying to prepare video at the same time. After the error is occurred, it seems all the Media service is error on the device, e.g. the native Camera app, and native VideoPlayer app cannot work until I reboot the device. The error only happen on the S2, while the same code works well on my other devices (e.g., Galaxy S3 JB, Nexus 4 JB_MR1, and some other ICS devices). My question is what is the difference between S2 (SGH-T989) and other devices in their Media framework? The source code is already attached in message. The logcat looks like below: 04-30 14:30:24.218: I/Adreno200-EGLSUB(7938): <ConfigWindowMatch:2078>: Format RGBA_8888. 04-30 14:30:24.338: E/MediaPlayer(7938): error (1, -12) 04-30 14:30:24.368: E/MediaPlayer(7938): error (1, -12) 04-30 14:30:24.408: E/MediaPlayer(7938): Error (1,-12) 04-30 14:30:24.408: D/VideoView(7938): Error: 1,-12 04-30 14:30:24.408: E/VideoPlayActivity(7938): onError. what=1 extra=-12 04-30 14:30:24.428: E/MediaPlayer(7938): Error (1,-12) 04-30 14:30:24.428: D/VideoView(7938): Error: 1,-12 04-30 14:30:24.428: E/VideoPlayActivity(7938): onError. what=1 extra=-12 Thanks. -- Kan Wu [email protected] -- -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
