android-videoview

问题 I want to play 2 videos in a row. The first video always plays just fine. After it finishes, you can see in the log that it sets the new video URL, but then SurfaceView throws an error and the VideoView just freezes with the last frame of the first video. Nothing else happens. Any thoughts ? Thanks ! LE: Surprisingly, the OnPreparedListener gets called for the second video. LE2: Sometimes the second video plays just fine, sometimes it doesn't... and I haven't changed a line of code between

问题 I'm building an app that records and plays back video. I would like to do so without affecting background music playback, i.e. if I begin playing a video, I do not want to pause other apps' audio. However, on Lollipop, Android's VideoView class automatically requests audio focus when the private method VideoView.openVideo() is called: AudioManager am = (AudioManager) super.getSystemService(name); am.requestAudioFocus(null, AudioManager.STREAM_MUSIC, AudioManager.AUDIOFOCUS_GAIN); Any

问题 Is there a way to step through a video file frame by frame? I've tried using a VideoView and I've had minor success. I can get the video the step through key frames but not individual frames.

(As opposed to the earlier framework's

问题 I'm currently developing a video player for android. I've created a simple textview that shows the current subtitle. The problem is: MediaPlayer getCurrentPosition() method only gives me time in seconds. And I need that value in milliseconds to correctly synchronize the subtitle with the movie. The getCurrentPosition is supposed to give me the time in milliseconds, but it gives the time in seconds*1000 (every number ends with "000"). Do you know a better way of doing this? How do I get the

问题 I have a problem that I have been trying to find a solution for a long time. My situation is as follows: I have an app that downloads zipped videos and unzips them at the application's private folder and more specifically at a subfolder. For example at /data/data/my.app.package.name.here/files/assets/assets-955. Inside this folder the video is unzipped. The unzipping process is completed successfully since I can pull and view the video without problems when running the app on the emulator. I
