How To Convert Codec Of Video Recorded By Inbuilt Android Camera?

I record video using the inbuilt camera of android,but when I send to server via Retrofit2,the video cannot seen in browser.So after long time of searching,I know that the video th

Solution 1:

(1) Fixing current video file :

Your video is of format H.263 (or Mpeg-2) using Simple profile. Correctly as you said, this means you must convert. You must do this re-encode into H.264 task using some free video tool.

For example : Using Handbrake you can do...

• Choose to Open your "not playing" MP4 file. Should be detected as MP4, now tick (or enable) the option web optimized.

• In Video settings tab, choose EncoderProfile as Main and Encoder level as 3.

• In Destination put your preferred output folder and filename. (just browse to some folder then type your new filename to create here).

• Click green button Start Encode and test new MP4 output file in browser.

(2) Fixing Android code for future recordings :

You have to set the codec to H.264 in your MediaRecorder object settings like :

myMediaRec = newMediaRecorder(); //create MediaRecorder object
myMediaRec.setVideoEncoder(MediaRecorder.VideoEncoder.H264); //set video codec

So basically your code should look like : (untested code, just use for study or guidance)...

@OverrideprotectedvoidonActivityResult(int requestCode, int resultCode, Intent data) 
{
    if(requestCode == RECORD_VIDEO_PERMISSION && resultCode == RESULT_OK)
    {
        //# Create a new instance of MediaRecorder
        myMediaRec = newMediaRecorder(); //create MediaRecorder object
        mMediaRec.setVideoSource(MediaRecorder.VideoSource.CAMERA);
        mMediaRec.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
        myMediaRec.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);

        //# Video settings
        myMediaRec.setVideoEncoder(MediaRecorder.VideoEncoder.H264); //contained inside MP4
        myMediaRec.setVideoSize(640, 480); //width 640, height 480
        myMediaRec.setVideoFrameRate(30);  //30 FPS
        myMediaRec.setVideoEncodingBitRate(3000000); //adjust this for picture quality//# Audio settings
        myMediaRec.setAudioEncoder(MediaRecorder.AudioEncoder.AAC); //must always be AAC
        myMediaRec.setAudioEncoder(MediaRecorder.getAudioSourceMax());
        myMediaRec.setAudioEncodingBitRate(16);
        myMediaRec.setAudioSamplingRate(44100);

    }
}
