Using MediaCodec to compress video

Question

I'm trying to use MediaCodec in Android to compress videos.

It looks like MediaCodec will give you back the raw stream. Is there a way to go from A->B (compress video with an output file at the end)?

Thanks.

You can employ the MediaMuxer class to store the elementary streams into a file format like MP4 . Please refer to this cts example for a good illustration of transcode + muxing where the encoded data is written into a file through the MediaMuxer .
