使用 MediaRecorder 在 HTC Rezound 摄像机上录制 1080p 视频

Rezound 上的内置相机应用程序能够以 1080p 录制视频，但我在通过 Android API 执行此操作时遇到困难。如果我使用 CamcorderProfile.QUALITY_HIGH 中的设置，一切都会很好，但这只能提供 720x480 的视频。当我尝试将分辨率提高到 1080p 时，我的应用程序在 MediaRecorder.start() 上冻结，并且任何尝试使用相机的应用程序都会停止工作，直到我重新启动手机。

这是我用来配置 MediaRecorder 的代码：

CamcorderProfile prof = CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH);
if(false){
    prof.videoFrameHeight=1080;
    prof.videoFrameWidth=1920;
}
prof.videoFrameRate=24;
prof.audioCodec=MediaRecorder.AudioEncoder.AAC;
prof.audioSampleRate=44100;
prof.audioBitRate=96;
prof.audioChannels=2;
mMediaRecorder.setProfile(prof);

当我启用 if 块内的代码时，应用程序冻结。我尝试准确复制从本机相机应用程序录制 1080p 时获得的视频设置。

如果能找到 Rezound 上使用的本机相机应用程序的来源，那就太好了。我检查了 Android 2.3.4 版本中的本机相机应用程序，它看起来不能支持任何高于 CamcorderProfile.QUALITY_HIGH 中指定的分辨率。

The built-in camera app on the Rezound is able to record video at 1080p, but I'm having trouble doing this from the Android API. Everything works great if I use the settings in CamcorderProfile.QUALITY_HIGH, but that only gives me video at 720x480. When I try to increase the resolution to 1080p, my app freezes on MediaRecorder.start() and any app that tries to use the camera stops working until I restart my phone.

Here's the code I'm using to configure MediaRecorder:

CamcorderProfile prof = CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH);
if(false){
    prof.videoFrameHeight=1080;
    prof.videoFrameWidth=1920;
}
prof.videoFrameRate=24;
prof.audioCodec=MediaRecorder.AudioEncoder.AAC;
prof.audioSampleRate=44100;
prof.audioBitRate=96;
prof.audioChannels=2;
mMediaRecorder.setProfile(prof);

The app freezes when I enable the code inside the if block. I've tried to exactly copy the settings of the videos I get when I record 1080p from the native camera app.

It would be great to track down the source of the native camera app used on the Rezound. I checked out the native camera app in the 2.3.4 release of Android and it doesn't look like it can support any resolution higher than the one specified in CamcorderProfile.QUALITY_HIGH.
