You can speed up or slow down audio with the atemto audio filter.The atempo filter is limited to using values between 0.5 and 2.0 (so it can slow it down to no less than half the original speed, and speed up to no more than double the input).To slow down the audio to half of its speed we have to use atempo value 0.5. For example, if there are two succesive frames shown at timestamps 1 and 2, and you want to slow down the video, those timestamps need to become 2 and 4, respectively.Thus, we have to multiply them by 2.0. The filter works by changing the presentation timestamp (PTS) of each video frame.To slow down your video, you have to use a multiplier greater than 1. I have used RangeSeekBar to allow user to select the time range for cutting video from original video.Ĭomplete code for the post is uploaded on github at below link-Īnd an extended app is published on play store-ġ.Add FFmpeg dependency in app module gradle file and sync project.Ĭompile ‘com.writingminds:FFmpegAndroid:0.3.2’įfmpeg.loadBinary(new LoadBinaryResponseHandler() void onFailure() void onSuccess()
