How to stream music with Windows Media Player 12

I recently getting problem in soundcloud where i can't play some tracks. After trying 3 times, i decided to open Web Console(Ctrl+Shift+K in Firefox) which shows me some security warnings. One of them is refer to "api dot soundcloud dot com / bla bla.. / streams" that says Cross-Origin Request is blocked. I'm spending about half-hour to activate CORS but Firefox seems not support that thing.



But...
I remember Internet Download Manager that sometimes shows "Download This Audio". Maybe i can do some kind of experiment with those links, ok, i decide to open the link and it shows some kind of JSON data like this:
{"http_mp3_128_url":"some_links_here","preview_mp3_128_url":"some_links_here_2"}
 
Maybe the "some_links_here" contains the mp3 file which can be used to stream the mp3 from WMP instead.
I try to copy the "some_links_here" link and paste it to WMP for stream and it worked. Here's how
1. Open Windows Media Player
1.a. For faster, just press Win+R and type "wmplayer"
2. Press Ctrl+U and paste the link at there
3. Press OK.
4. Wait for some time and it will start to stream the mp3 from your WMP.
4.a. If it shows error, maybe the link already expired, in that case, try to reopen the soundcloud page.
Well, after some investigation that i do myself, it seems that it only throws security warning when it try to use "OPTIONS" request method instead of "POST"(maybe) or "GET".

Okay, one more question. How to do this in OneDrive?
Okay i also have a story about this today. I'm uploading 3 files to my OneDrive and only 1 file is uplaoded with very slow speed.
Then, after the file has beed uploaded successfully, it shows that the rest of 2 files(that failed) has beed uploaded successfully too.
I need to verify that those 2 files doesn't corrupted first so i do these things:
1. Right click the file you want to stream
2. Click Download
3. When download dialog pops up, try to copy only the link.
3.a. If it doesn't allow you to do so(like bulit-in firefox download), try to press "Download" and then abort it(also read 3.b for next steps for this)
3.b. Shows your download(Ctrl+J) and you find your aborted download. Right click on it and press "Copy Download Link"(or something similar)
4. Repeat step 1-4 above(in soundcloud stream method)

 }
 std::cout << "Accent: " << accent.r << "," << accent.g << "," << accent.g << endl << "Background: " << background.r << "," << background.g << "," << background.b << endl;
 return 0;
}

Note1: It also work in Windows 8.1 without any edits
Note2: It can be ported to C with some editing.
Note3: I give a bonus code. You can use get_winver to get windows version(which i think is better than GetVersionEx)

[Lua]Get BPM/Tempo from WAV file

How do i get the tempo from WAV file? nah some Lua code can do that.

local function num2float (c)	-- http://stackoverflow.com/questions/18886447/convert-signed-ieee-754-float-to-hexadecimal-representation
	if c == 0 then return 0.0 end
	local c = string.gsub(string.format("%X", c),"(..)",function (x) return string.char(tonumber(x, 16)) end)
	local b1,b2,b3,b4 = string.byte(c, 1, 4)
	local sign = b1 > 0x7F
	local expo = (b1 % 0x80) * 0x2 + math.floor(b2 / 0x80)
	local mant = ((b2 % 0x80) * 0x100 + b3) * 0x100 + b4
	if sign then
		sign = -1
	else
		sign = 1
	end
	local n
	if mant == 0 and expo == 0 then
		n = sign * 0.0
	elseif expo == 0xFF then
		if mant == 0 then
			n = sign * math.huge
		else
			n = 0.0/0.0
		end
	else
		n = sign * math.ldexp(1.0 + mant / 0x800000, expo - 0x7F)
	end
	return n
end
 
local function int2char(int)
	return string.char(int%256)..string.char(math.floor(int/256%256))..string.char(math.floor(int/256/256%256))..string.char(math.floor(int/256/256/256))
end
 
local function char2int(char)
	return char:sub(1,1):byte()+char:sub(2,2):byte()*256+char:sub(3,3):byte()*65536+char:sub(4,4):byte()*16777216
end
 
function getWAVTempo(wav,verbose)
	local vp=function() end
	local f
	if verbose then vp=print end
	vp("getWAVTempo start!")
	if type(wav)=="userdata" then
		vp("#1 type is userdata. Assuming it's a file type!")
		f=wav
	else
		vp("#1 type is string. It's path to wav file")
		f=assert(io.open(wav,"rb"))
	end
	if verbose then vp=function(txt) print("["..string.format("%08X",f:seek("cur")).."] "..txt) end end
	local curSeek=f:seek("cur")
	local fileSize=f:seek("end")
	f:seek("set")
	if f:read(12)=="RIFF"..int2char(fileSize-8).."WAVE" then
		vp("WAV File header correct. Reading chunks!")
		while(f:seek("cur")~=fileSize)do
			local chunk=f:read(4)
			if(chunk=="acid")then
				vp("\"acid\" chunk found. Getting tempo data!")
				f:read(24)
				tempo=num2float(char2int(f:read(4)))
				vp("Tempo data found!")
				if type(wav)=="string" then f:close()
				else f:seek("set",curSeek) end
				return tempo
			else
				local size=char2int(f:read(4))
				vp("\""..chunk.."\" chunk found with size of "..size..". Skipping...")
				if size%2==1 then size=size+1 end
				f:seek("cur",size)
			end
		end
	else
		error("Invalid wav file!")
	end
	if verbose then print("Tempo data not found!") end
	if type(wav)=="userdata"then f:seek(curSeek)
	else f:close() end
	return 0
end

What do you need to do is:
  1. Save code above to file
  2. dofile it
  3. call getWAVTempo(file[,verbose])
    getWAVTempo Parameters:
    file - file handle(from io.open) or string to filename
    verbose - show more message. If you set this to true, you can see what's going on.
  4. a. If it returns 0, then the wav file does not come with embedded tempo data
    b. If it returns value more than 0, then that's the tempo. Please note that the decimals is stripped on return.
That's it.
Feel free to use some (or all) parts of code above.

[C#]Synaptics custom touchpad gesture code.

Nah, my laptop cannot use updated version of the synaptics touchpad driver. The driver that comes with it does lack of using some windows 8 touchpad gesture. I'm start to think, maybe i can access the Synaptics API and yes, that's possible. After a lot search in google, i have a code that allows to switch to Windows apps and show Charm bar with touchpad gesture.

If someone need it, feel free to check my source code(well, it's dirty written)(Requires Input Simulator)
