Companion plugin for the DropTracker RuneLite plugin.
This plugin contains the GPU-accelerated (LWJGL/OpenGL PBO) frame-capture engine used to record short gameplay clips of drops, personal bests, and other achievements. It is kept separate from the main DropTracker plugin so that the OpenGL surface is small, isolated, and easy to audit.
- The plugin does nothing on its own. It idles until the main DropTracker plugin asks
it to start recording via RuneLite's
PluginMessageevent (namespacedroptracker-video). - While recording, it keeps a rolling in-memory buffer (~10 seconds) of JPEG-compressed frames read back from the OpenGL front buffer via a small ring of Pixel Buffer Objects. Nothing is written to disk and nothing is uploaded by this plugin.
- When the main plugin requests an event clip, the buffered frames (plus a final
screenshot) are handed back to the main plugin in-memory via
PluginMessage. The main plugin is responsible for any uploading. - Login screens and bank-PIN interfaces are detected and blurred before frames leave the buffer.
- Requires the GPU plugin (or another plugin providing an OpenGL context). Without one, it reports capture as unavailable and the main plugin falls back to screenshots.
