increase brightness gets blurry

[sanmool]

Hi

After installing VLC-Android from google play, I could increase the brightness.
It increases the brightness and color gets clearer as I increase the brightness, it improves picture quality.

However, When I use the code

Code: Select all

libvlc_video_set_adjust_int(vlcPlayer, libvlc_adjust_Enable,1); libvlc_video_set_adjust_float(vlcPlayer, libvlc_adjust_Brightness, 1.5);

The result is,

https://ibb.co/HG4Y9LG -- after

it just makes the image whiter and picture becomes blurry with white color as you can see. It feels like putting a white paper on top of the picture.
It seems changing brightness on VLC-Android does not use above code. How can I get the same effect as VLC-Android did? Thank you for reading.

It turns out that that's not about the brightness of video player, it was the brightness of android device. So we could do it using the function

Code: Select all

void changeBrightness(float delta) { // Estimate and adjust Brightness final WindowManager.LayoutParams lp = getWindow().getAttributes(); float brightness = Math.min(Math.max(lp.screenBrightness + delta, 0.01f), 1f); setWindowBrightness(brightness); brightness = Math.round(brightness * 100); showInfoWithVerticalBar(getString(R.string.brightness) + "\n" + (int) brightness + '%', 1000, (int) brightness, 100); }

But it is not about vlc. I will delete this post once I find how to do it.
