Given that the "vlc.dialog:add_image()" function only works with local images, what's the best way to display a remote image in a dialog box? I want to avoid using an external command (e.g. wget) to download the image to disk first. The extension shown in this article might do what I want, but I can't seem to find its source code anywhere. Does anyone know where I can find it or how to go about displaying remote images in dialog boxes?

I figured out how to work-around this inability. For the benefit of others, below is the code I'm using. I've assumed that artist image files (300x300) won't be larger than 1 MiB. Let me know if anyone knows of a better method.

Code: Select all

function get_artist_image_filename()
	local url = get_artist_image_url()
	if url == nil then return nil end
	local stream = vlc.stream(url)
	if stream == nil then return nil end
	local data = stream:read(1024*1024)
	if data == nil then return nil end
	local fname = os.tmpname()
	if fname == nil then return nil end
	--local fhandle = io.tmpfile()
	local fhandle = io.open(fname, "wb")
	--local fhandle = assert(io.open(fname, "wb"))
	if fhandle == nil then return nil end
	fhandle:write(data)
	fhandle:close()
	return fname
end
