Android get video rotation from metatags

currently I am using the Android MediaMetadataRetriever class in order to get the video rotation tag from a MP4 file, using the MediaMetadataRetriever.METADATA_KEY_VIDEO_ROTATION tag. The main drawback of this, is that is only compatible with API level 17 and up, and the minimum supported API level desired for the application is 14.

Is there any work around for this, I tried using the ffmpeg library that used in the project, but I did not find an option to get this tag from the video.

Thanks in advance.

The latest version of FFmpegMediaMetadataRetriever has support for the METADATA_KEY_VIDEO_ROTATION tag, I recommend trying that library.

Well, It turn outs that ffmpeg does actually returns the Rotation from the metadata info of the video using the -i option:

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'original180.mp4':

Hope it helps someone.
