Add AssHandlerConfig.maxRenderPixels to limit subtitle render resolution. When frame size exceeds this pixel count, rendering is proportionally downscaled and then scaled back up during display. This reduces CPU and memory usage on high-resolution devices (e.g., 4K TVs).

Changes:

  • AssHandlerConfig: add maxRenderPixels parameter (default 0 = no limit)
  • AssHandler: add computeRenderSize() utility, apply to all setFrameSize calls, log downscaling when triggered from onSurfaceSizeChanged
  • AssSubtitleTextureView: scale glViewport coordinates from renderSize to surfaceSize
  • AssSubtitleCanvasView: scale drawBitmap with RectF when downscaled
  • AssTexOverlay: create smaller FBO, override getVertexTransformation to scale up in OverlayEffect pipeline
  • AssCanvasOverlay: scale canvas draw coordinates
  • AssPlayer.kt: expose config parameter in buildWithAssSupport()
  • README: document configuration and downscaling behavior

Add AssHandlerConfig.maxRenderPixels to limit subtitle render resolution. When frame size exceeds this pixel count, rendering is proportionally downscaled and then scaled back up during display. This reduces CPU and memory usage on high-resolution devices (e.g., 4K TVs).
Changes:
  • AssHandlerConfig: add maxRenderPixels parameter (default 0 = no limit)
  • AssHandler: add computeRenderSize() utility, apply to all setFrameSize calls, log downscaling when triggered from onSurfaceSizeChanged
  • AssSubtitleTextureView: scale glViewport coordinates from renderSize to surfaceSize
  • AssSubtitleCanvasView: scale drawBitmap with RectF when downscaled
  • AssTexOverlay: create smaller FBO, override getVertexTransformation to scale up in OverlayEffect pipeline
  • AssCanvasOverlay: scale canvas draw coordinates
  • AssPlayer.kt: expose config parameter in buildWithAssSupport()
  • README: document configuration and downscaling behavior
