Version

Media3 1.9.2

More version details

I'm experiencing an issue where the artwork displayed in the media notification and on the lock screen appears heavily pixelated / blurry, even though the source image is high quality.
The image used is a 1024x1024 PNG, so resolution should be sufficient.
The issue has been specifically observed on Samsung devices.

Image format: PNG
Resolution: 1024x1024

I also tried:

• Passing artwork as a ByteArray
• Converting the image locally to WebP from ByteArray
• Bump library to 1.10.0-rc02

The issue persists in all cases

internal fun MyAudio.mapToMediaItem(): MediaItem {
    return MediaItem.Builder()
        .setUri(audioEndpoint)
        .setMediaId(id.toString())
        .setMediaMetadata(
            MediaMetadata.Builder()
                .setArtworkUri(artworkUrl?.toUri())
                .setTitle("Title")
                .setDescription("Description")
                .build()
        )
        .build()
}
