setVideoSize()以高分辨率崩溃

Question

我想给用户一个设置不同分辨率的选项.

我试过这个解决方案

camcorderProfile = CamcorderProfile.get(CamcorderProfile.QUALITY_720P);
....
....
mCamera.unlock();
recorder.setCamera(mCamera);
recorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT);
recorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
recorder.setProfile(camcorderProfile);

它完美地工作:质量好,一切......

当我把它设置为

camcorderProfile = CamcorderProfile.get(CamcorderProfile.QUALITY_480P);

随着FLASH,视频出现了绿色和其他一些奇怪的颜色.

我在线阅读,人们说这是因为我的手机可能不支持QUALITY_480P.好吧,它会让人感觉到.

因此,我开始研究不同的解决方案,所以我试过......

recorder.setVideoSize(640, 480);

效果很好,

但视频看起来非常难看.

接下来,我检查了支持的视频列表.

List<Size> GetSupportedVideosResolutions =  params.getSupportedVideoSizes();

分辨率:1280x720在列表中,所以

我试图设置以下内容:

recorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT);
recorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
recorder.setVideoSize(1280,720);
recorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT); 

它给了我一个RuntimeException错误.

问题是

为什么不能让我设置手机上可用的更高分辨率？

任何帮助将不胜感激,

谢谢.

Answer 1

我想出了问题所在。这可能对其他人有帮助。我最终得到：

camcorderProfile = CamcorderProfile.get(CamcorderProfile.QUALITY_720P);
recorder.setVideoSize(1280, 720);   //NEEDED or it will crash

代码：

camcorderProfile = CamcorderProfile.get(CamcorderProfile.QUALITY_720P);
....
....
mCamera.unlock();
recorder.setCamera(mCamera);
recorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT);
recorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
recorder.setProfile(camcorderProfile);
recorder.setVideoSize(1280 720);  //NEEDED or it will crash
....
...

//或者

CamcorderProfile.get(CamcorderProfile.QUALITY_1080P);
recorder.setProfile(camcorderProfile);
recorder.setVideoSize(1920, 1080);  //NEEDED or it will crash
