TransformationOptions giving corrupt video

[AsitDixit]

I don't know is this a right place to ask doubts, but I need your help. My problem is this lib has less documetation.
I want to:

1. Trim vieo
2. compress video (maintaining original aspect ratio, width height can be decreased)
3. adding my custom image at bottom left corner with some margin to bottom and left side. One thing I want to maintain constant ratio of bitmap overlay width and height to the height & width of video.

        TransformationOptions transformationOptions = new TransformationOptions.Builder()
                .setGranularity(MediaTransformer.GRANULARITY_DEFAULT)
                .setVideoFilters(null)
                .setSourceMediaRange(new MediaRange(1000,5000))
                .build();

When adding null in place of TransformationOptions in mediaTransformer.transform it is working fine. But with above code it is not giving any error but producing an empty file. Am I missing something?

SORRY I'm beginner

I think the problem here is with MediaRange values. They are supposed to be in microseconds, not in milliseconds. I assume you are trying to trim the video between 1 and 5 seconds. So values here should be 1_000_000 and 5_000_000, not 1_000 and 5_000

Okay but I saw LiTr is using many deprecated api please update them.

  MediaFormat targetVideoFormat = new MediaFormat();
                targetVideoFormat.setString(MediaFormat.KEY_MIME, "video/avc");
                targetVideoFormat.setInteger(MediaFormat.KEY_WIDTH, 100);
                targetVideoFormat.setInteger(MediaFormat.KEY_HEIGHT, 150);
                targetVideoFormat.setInteger(MediaFormat.KEY_BIT_RATE, 4800);
                targetVideoFormat.setInteger(MediaFormat.KEY_I_FRAME_INTERVAL, 5);
                targetVideoFormat.setInteger(MediaFormat.KEY_FRAME_RATE, 30);
                targetVideoFormat.setInteger(MediaFormat.KEY_COLOR_FORMAT, MediaCodecInfo.CodecCapabilities.COLOR_FormatSurface);

Here HEIGHT=150 & WIDTH=100 but output is opposite of this.

Here HEIGHT=150 & WIDTH=100 but output is opposite of this.

Is there a rotation flag? If rotation flag is present (90 or 270 degrees) it is preserved and video will be rotated when played, which will make it look like that width and height are switched.
