更多信息
After installing the extension, you'll be prompted to download the helper. One-time setup, runs in the background automatically after that.
Why a helper app? Browser extensions alone can't re-encode video, merge clips, or record live streams — these need real media tools (ffmpeg, yt-dlp). Keeping them in a local helper means all processing stays on your computer. Nothing is ever uploaded to any server.
Download the helper here: https://codeberg.org/alper-ux/qolva-helper
