24-bit RGB resolution for album art option is greyed out


Recommended Posts

Poweramp v3 build 871 (full)

Redmi 2 1gb+8gb (wt88047)

Android 9.0 Pie

Custom ROM (AospExtended ROM V6.6)

While my MP3 file has an embedded 1500x1500 image, Poweramp is showing me a 750x750 image as the album art of the song. Even if I select the High Resolution option, it is still very pixelated. The 24-bit RGB toggle is disabled for me under the advanced tweaks in the Album Art set of options. The image is really blurry on all the songs, I don't have this issue with my other phone, every image is crisp and clear. I have only seen this problem on the Redmi 2. I'm really sorry if my post breaks any rules or already addressed bugs. Thanks in advance!

This is the actual size of the image that Poweramp tells me when high resolution is checked (it is unchecked by default on this phone only). But even when I select the 1500x1500 image, nothing happens and it is still pixelated. Is it a bug that has an easy fix? Or is it something to do with Android?

Hello, you have recently released an update with a new option to Increase Resolution under Album Art, this option is greyed out too on my Redmi. I am able to enable 24-bit RGB album art on my Samsung S II which has a screen resolution of 800x480, but the Redmi 2 has a higher resolution of 1280x720 and still no luck with better quality of the album art. Both devices have 1 GB of ram. Please help me resolve this issue, I couldn't find a solution anywhere! If you know about one, please link it and let me know and I'll tell you the results. Thanks!

@SaneComputing this is because your device allocates less than 128mb per app. Each 24bit image is 4-18mb and we need some memory for player itself;-)

PS per image memory allocation depends on color depth (24/16 bit), dimensions (Poweramp uses 512x512, 1024x1024, 1536x1536 texture sizes) and hardware bitmap format support, which reduces memory taken by 2 (Android 9+, except meizu which has this feature broken).

So standard hi-res 24 bit 1024x1024 image takes 1024(size)*1024(size)*4(24bits color)*2(pre-9 Android “tax”) = 8mb on Android pre-9, 4mb for Android 9+.

Thank you for clarifying.

I just checked the new version again, the album art images are smooth now instead of being pixelated on this device. I'm happy with that at the moment :D I can try to show you from the attached image that it looks much better now. It's not the highest quality of the source image, but it looks fine.

Anyway, I would like to thank you both for your time and generous help!
