Detailed Description

Renderer for intra-only video codecs with instant seeking.

Unlike VideoNodeRenderer which reads from a frame queue fed by a background thread, this renderer owns its own LibAV decoding context and performs synchronous seek + decode + GPU upload directly in update().

This enables instant seeking for all-intra codecs (ProRes, MJPEG, DNxHD, HAP, etc.) where every frame is independently decodable.

Supports hardware-accelerated decoding when available (VAAPI, D3D11VA, CUDA, VideoToolbox, Vulkan Video). When zero-copy GPU texture import is not possible for the current RHI backend, falls back to av_hwframe_transfer_data() which still avoids software decode CPU cost.
