Android : H.264 인코딩 및 Framerate 작동하지 않음 설정

Question

HTC MyTouch 3G 슬라이드 (Android 2.1, API 레벨 7)가 있습니다. 15fps에서 320x240 h.264 비디오를 녹화하는 프로그램을 작성하려고하는데 2 가지 주요 문제점이 있습니다. 어느 쪽의 문제에 대한 해결책에 대해 고맙게 생각합니다. 여기에 내가 뭐하는 거지 : 1) H263 및 MPEG_4_SP가 잘 작동

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(); 

문제지만, H264하지 않습니다. 호출) (제조에서 로그 캣 아래 오류 충전 :

문제 2) 명시 적으로 프레임 속도를 15fps로 설정했지만 클립의 사후 분석은 21.xx 또는 25.xx fps와 같은 이상한 프레임 속도를 보여줍니다.

왜 H264가 작동하지 않고 MediaRecorder가 요청한 프레임 속도를 따르지 않을 수 있습니까? 미리 감사드립니다.

Answer 1

H.264는 Android 3.0+에서만 지원됩니다.

CamcorderProfile에서 장치가 지원하는 인코딩 프로파일을 확인하십시오.

Answer 2

문제 1)
구성 요소는 H.264 인코딩을 지원하지
휴대 전화를 처리 OMX.PV.avcenc 가져올 수 없습니다.
