I have introduced an AssHandlerConfig with defaults for the glyph and cache that preserve the existing behavior but allows applications to configure the cache limits based on their needs.
I was able to test a glyph size of 10000 and a cache size of 128 MB for a few months playing media heavily on a Shield TV and found the experience to be much smoother. I only crashed one time.
Usage is as simple as setting the config when you new up the AssHandler.
private val assHandler by lazy { AssHandler(AssRenderType.OVERLAY_CANVAS, config = AssHandlerConfig(glyphSize = 10000, cacheSize = 128)) }The config and all members within the config are optional so a consumer can mix and match their own settings based on their needs.
