Android Video Compression/Downsampling library

For our android applications we need a generic library that reduces a video taken by the user in size and output it as a smaller-size H264 formatted video that can be easily uploaded. To achieve this, the video needs to be downsampled to a resolution (configurable) and also the video needs to be rotated if the device has saved it with an EXIF property (that property needs to be removed and the video needs to be outputted as top-up).
