Input: front Camera captured videos with OrientationHint set at 270 to make end result as Portrait video.

Action: Resize(Downsample)

Behaviour in Lollipop: The videos are auto rotated to portrait format. So we have to pass Resolution.360p.getWidth() as height and Resolution.360p.getHeight() as width. The end result is proper portrait videos (video completely changed to portrait, not the metadata or container orientation)

Behaviour in Kitkat: The videos are in landscape mode.

Why this difference in behaviour? I would like to get the behaviour as in Lollipop, so that the video is completely transformed to 360x640 portrait resolution

Your code work perfectly when set birate greater than 2073600, however when i set it lower than 2073600 (1000000 for example), it will automatically change back to 2073600. I using Android 12 API 31 Pixel 5.

I recored one video from camera with width=864 and height=480.

When I scale it down by 2, then the video get compressed with no issues.

But when I scale it down by 4, then I get warning : width or height not multiple of 16 and below exception :
java.lang.IllegalStateException at android.media.MediaCodec.dequeueOutputBuffer(Native Method) at VideoResampler.resampleVideo(VideoResampler.java:376) at VideoResampler.feedClipToEncoder(VideoResampler.java:245) at VideoResampler.resampleVideo(VideoResampler.java:208) at VideoResampler.access$200(VideoResampler.java:37) at VideoResampler$VideoEditWrapper.run(VideoResampler.java:165) at java.lang.Thread.run(Thread.java:841)

Is the issue related to scaling?

There is no audio in generated video file.
I have used this code,

VideoResampler resampler = new VideoResampler();
        resampler.addSamplerClip(new SamplerClip(inputUri));
        resampler.setOutput(outputUri);
        resampler.setOutputResolution(Resolution.RESOLUTION_360P.getWidth(), Resolution.RESOLUTION_360P.getHeight());
        try {
            resampler.start();
        } catch (Throwable e) {
            e.printStackTrace();
        }
