我有一个HTC MyTouch 3G幻灯片(Android 2.1,API级别7)。我正试图编写一个程序以15fps记录320x240 h.264视频,但我有两个主要问题。我会感谢解决这两个问题。下面是我在做什么:Android:视频编码H.264和设置帧率不工作

mediaRecorder = new MediaRecorder(); 
mediaRecorder.setCamera(camera); 
mediaRecorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT); 
mediaRecorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT); 
mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4); 
mediaRecorder.setMaxDuration(600000); 
mediaRecorder.setOutputFile("/sdcard/test.mp4"); 
mediaRecorder.setVideoFrameRate(15); 
mediaRecorder.setVideoSize(320, 240); 
mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); 
mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264); 
mediaRecorder.setPreviewDisplay(holder.getSurface()); 
mediaRecorder.setMaxFileSize(maxFileSizeInBytes); 
mediaRecorder.prepare(); 
mediaRecorder.start(); 

问题1) H263和MPEG_4_SP做工精细,但H264没有。在电话会议上准备()时,logcat中充满了以下错误:

问题2 )尽管我明确将帧速率设置为15fps,但剪辑的后分析会显示像21.xx或25.xx fps这样的奇怪帧速率。

为什么H264不能正常工作,为什么MediaRecorder不能遵守我请求的帧频?提前致谢。

你是否能够正常使用内置摄像头应用程序保存在h263和h264中? – fazo 2011-03-03 05:07:57

内置的相机应用程序为我提供了h263和mpeg4sp选项。我明白janin(下面)是正确的...而且我的设备不支持h264。 – 2011-03-14 01:48:51

H.264仅在Android 3.0+中受支持。

检查CamcorderProfile以了解您的设备支持哪些编码配置文件。

用于H264的Eclipse MediaRecorder附带的文档声明它是API 3+,而不是Android 3.0+ – Guardanis 2012-07-20 00:06:09

问题1)
无法获得部件OMX.PV.avcenc处理
您的手机不支持H.264编码。
