Starting from Android 4.1 (API level 16) MediaCodec APIs have been introduced. These APIs support Elementary stream Decoding & Encoding. Also MediaExtractor API will give elementary track details by analyzing Media streams.
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?
Thanks, Satish.
As of Android 4.3 (API 18) you can use the MediaMuxer class to convert the raw H.264 stream to a .mp4 file (and even merge an audio stream in).
See the EncodeAndMuxTest and CameraToMpegTest sources on this page for sample code.
