We can compress video using ffmpeg in android.

For integrating FFmpeg in android we can use precompiled libraries like ffmpeg-android.

You can use below command to compress video

String[] command = {"-y", "-i", inputFileAbsolutePath, "-s", "160x120", "-r", "25", "-vcodec", "mpeg4", "-b:v", "150k", "-b:a", "48000", "-ac", "2", "-ar", "22050", outputFileAbsolutePath};

Here,

-y

Overwrite output files without asking.

-i

ffmpeg reads from an arbitrary number of input “files” specified by the -i option

-s

video output size

-r

Set frame rate

-vcodec

Set the video codec.

-b:v

Set the video bitrate

-b:a

Set the audio bitrate

-ac

Set the number of audio channels.

-ar

sets the sampling rate for audio streams if encoded
