视频兼容性问题:Android录制的视频无法在iPhone中播放 [英] Video compatibility issue: android recorded video not played in iphone

问题描述

我正在像这样在android中录制视频

I am recording a video in android like this

List<Camera.Size> list =  myCamera.getParameters().getSupportedPictureSizes();
            Parameters parameters = myCamera.getParameters();
            parameters.setColorEffect(coloreffects.get(index_color_effect));
            myCamera.setParameters(parameters);
            mediaRecorder = new MediaRecorder();
            myCamera.unlock();
            mediaRecorder.setCamera(myCamera);
                mediaRecorder.setOrientationHint(90);
            mediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
            mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
            mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
            mediaRecorder.setAudioEncoder(AudioEncoder.HE_AAC);
            mediaRecorder.setVideoEncoder(VideoEncoder.H264);
            mediaRecorder.setOutputFile(Constants.videourl);
            mediaRecorder.setMaxDuration(30000); // Set max duration 60 sec.
            mediaRecorder.setVideoFrameRate(24);
             mediaRecorder.setVideoFrameRate(30);
             mediaRecorder.setVideoSize(720, 480);
            mediaRecorder.setPreviewDisplay(myCameraSurfaceView.getHolder().getSurface());

此录制的视频可以在android中正常播放，但无法在iphone上播放.

this recored video and able to play in android well but unable to play on iphone.

如果使用此代码进行录制

if if use this code for recording

         // work two
         {
         mediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
         mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);

         mediaRecorder.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH));
         mediaRecorder.setOutputFile(videourl);
         mediaRecorder.setMaxDuration(30000); // Set max duration 60 sec.
         }

此录制的视频与iPhone兼容. 但 这会在三星note2上录制30秒的视频(约47 mbs).

THis records video compatible.with iphone well. but this records 30 seconds video about 47 mbs on samsung note2.

有帮助吗?

推荐答案

iPhone支持MPEG-4视频格式的视频，且分辨率不大于640x480

The iPhone supports video in MPEG-4 video format, and at a resolution not larger than 640x480

尝试一下 mediaRecorder.setVideoSize(640，480);

try this mediaRecorder.setVideoSize(640, 480);
