how to play web url audio files corona sdk? - web

Question

I am trying to play audio file from web link but it seems not working now. These are the codes I tried:
local birdSound = audio.loadSound("www.sound.com/birds.mp3")
audio.play(birdSound)
It gives an error

Answer 1

You can't load in memory a remote audio file with the loadSound API because this function is just intended to load local files.
By default the file is searched for in the project folder (system.ResourceDirectory), but changing the baseDir parameter you can also look inside a different local folder.
So to play your remote audio file you should first dowload it in the system.DocumentsDirectory through the network.download API. When it is done you can load it with the loadSound, specifying the correct baseDir.
For details about the network.download API look here

Answer 2

Use the sniper below to download your remote file and then save it to localFilename at base dir basedir:
local xmnetwork = {
last_error = nil,
downloadHandlerInProgress = nil,
downloadHandlerFinished = nil,
downloadBeginHandler = nil,
network = require("network")
}
function xmnetwork.download(url, errorHandler,beganHandler, inProgressHandler, endedHandler, localFilename, basedir)
if( xmnetwork.network == nil) then
xmnetwork.network = require("network")
end
xmnetwork.downloadHandlerInProgress = inProgressHandler
xmnetwork.downloadHandlerFinished = endedHandler
xmnetwork.downloadBeginHandler = beganHandler
xmnetwork.errorHandler = errorHandler
local function downloadListener( event )
print("download event:" .. tostring(event))
if ( event.isError ) then
print( "Network error!" )
if( xmnetwork.errorHandler) then
xmnetwork.errorHandler(event)
end
elseif ( event.phase == "began" ) then
if ( event.bytesEstimated <= 0 ) then
print( "Download starting, size unknown" )
else
print( "Download starting, estimated size (in MB): " .. ( event.bytesEstimated /1024/1024))
end
if( xmnetwork.downloadBeginHandler) then
xmnetwork.downloadBeginHandler(event)
end
elseif ( event.phase == "progress" ) then
if(xmnetwork.downloadHandlerInProgress ) then
xmnetwork.downloadHandlerInProgress (event)
end
if ( event.bytesEstimated <= 0 ) then
print( "Download progress: " .. event.bytesTransferred )
else
print( "Download progress: " .. (event.bytesTransferred / event.bytesEstimated) * 100 .. "'%'")
-- log("xmnetwork.download", "downloading :" .. (event.bytesTransferred / event.bytesEstimated) * 100 .. "'%'")
end
elseif ( event.phase == "ended" ) then
print( "Download complete, total bytes transferred: " .. event.bytesTransferred )
if(xmnetwork.downloadHandlerFinished) then
xmnetwork.downloadHandlerFinished(event)
end
end
end
local params = {}
-- Tell network.request() that we want the "began" and "progress" events:
params.progress = "download"
-- Tell network.request() that we want the output to go to a file:
params.response = {
filename = localFilename,
baseDirectory = basedir
}
xmnetwork.network.request( url, "GET", downloadListener, params )
end
