decoder/ffmpeg: append file name suffix to virtual stream URL
To allow libavformat to detect the format of the input file, append the suffix of the input file to the URL of the virtual stream. This specifically enables the "shorten" codec, which is supported by libavformat/raw.c, detected only by the suffix.
