title: MP4 filewriter in android 4.1+
body: <p>Starting from Android 4.1 (API level 16) MediaCodec APIs have been introduced. These APIs support Elementary stream Decoding &amp; Encoding. Also MediaExtractor API will give elementary track details by analyzing Media streams.</p>
  
  <p>My Question is, I setup a video encoder using MediaCodec API, which gives me encoded file in .h264 format. I want to write .h264 file into a .mp4 file for playing/storing/sharing purposes. I don't find any .MP4 file-writer API for android.  Is there any way to achieve it?</p>
  
  <p>Thanks,
  Satish.</p>
