Direct playback renders through a worker-driven canvas and WebGL pipeline. The server
prepares HTTP-delivered HEVC segments, the browser buffers them in rolling 15-second
windows, and no video tag is used for the canvas path.
Waiting for a URL.
No media loaded
Load a remote video for canvas-based H.265 playback, upload directly to Vercel Blob,
or paste a YouTube link to let the background pipeline download and prepare HTTP
segments for canvas playback.
Canvas mode needs browser support for OffscreenCanvas, WebGL2, Fetch, and WebCodecs.
Direct URLs, Blob uploads, and YouTube links all flow through the same prepared HTTP
segment pipeline, and seeking reuses the prepared media timeline.
