Hi,
I’ve been lurking for a few weeks. I know streaming, and I know serving
audio and video files. My first project had to stream av files so I learned
how to do it with node. You need to work with content-length and you need
to send 206s instead of 200s when you get a range request.
function send(err,data){
if (err)
return send404(fileName)
cache.put(fileName,data,600000) // 10 minutes
var range = request.headers.range // bytes=0-1
if (!range){
response.writeHead(200, {
"Content-Type": mimeType,
"X-UA-Compatible": "IE=edge;chrome=1",
'Content-Length': data.length
});
response.end(data)
}else{
var total = data.length,
split = range.split(/[-=]/),
ini = +split[1],
end = split[2]?+split[2]:total-1,
chunkSize = end - ini + 1
response.writeHead(206, {
"Content-Range": "bytes " + ini + "-" + end + "/" + total,
"Accept-Ranges": "bytes",
"Content-Length": chunkSize,
"Content-Type": mimeType
})
response.end(data.slice(ini, chunkSize+ini))
// console.log('send',ini,chunkSize,end,total)
}
}
