Smooth Scrubbing Video In Android

I am trying to achieve smooth video scrubbing with Android VideoView. The seekTo method of MediaPlayer is not doing exactly what i want. It does not exactly seek to millisecond i p

Solution 1:

This is not a straight forward question to answer. I spent a month researching and implementing it myself.

The only way this can be achieved is using MediaCodec.

You can look at this project that does exact scrubbing using MediaCodec. The only issue I had with that project is that it takes time to load the buffer and display it on the surface, about 0.5 seconds.

You can also have a look at Grafica, especially the MoviePlayer class. Another source is the BigFlake website.

What I ended up doing is creating my own implementation using MediaCodec as none of them provided me exactly what I was looking for, as I was building a golf analyzer, I needed (real-time) precise (frame-per-frame) scrubbing of the video.

You can also look at a question I asked that is similar to this, where I added a lot of info on how I achieved this. Though this question is more about playing a video frame-per-frame, I think there is valuable info in it.
