Hook AVFormatContext.io_open so HLS/DASH segment fetches and other nested FFmpeg I/O go through stream_http when libcurl is available. This lets segments inherit the connection reuse, HTTP/2 multiplexing, mid-stream resume and conditional compression of the top-level stream. Falls back to FFmpeg's default I/O for non-HTTP URLs and when the curl backend is not built in.
