I think there is problem with fs read even file is there on specified path.

File upload on kaltura

var KalturaConstants = require('./KalturaTypes.js');
var Kaltura = require('./KalturaClient.js');

var KalturaClient = null;
var Session = null;

var pager = new Kaltura.objects.KalturaFilterPager();
pager.pageSize=10000;
pager.pageIndex=1;

var KALTURA_PARTNERID="#####";
var KALTURA_ADMINSECRET="##################";
var KALTURA_USERID="####";

var initialize = function(callback) {
var config = new Kaltura.KalturaConfiguration(parseInt(KALTURA_PARTNERID));
KalturaClient = new Kaltura.KalturaClient(config);
KalturaClient.session.start(function(session) {
KalturaClient.setKs(session);
Session = session;
callback();
}, KALTURA_ADMINSECRET, KALTURA_USERID, KalturaConstants.KalturaSessionType.ADMIN,
parseInt(KALTURA_PARTNERID), '10000000');
}

var uploadMedia = function(videoFile,userId) {

var fs = require("fs");

var DOWNLOAD_DIR = './downloads/';
var fileWithPath=DOWNLOAD_DIR+videoFile;

fs.exists(fileWithPath, function(exists) {
if (exists) {
fs.readFile(fileWithPath, "utf8", function(error, data) {
var uploadToken = null;
KalturaClient.uploadToken.add(function(token){

console.log("upload token added " + JSON.stringify(token));



KalturaClient.uploadToken.upload(function(token){

console.log("upload token uploaded " + JSON.stringify(token));

var entry = new Kaltura.objects.KalturaMediaEntry();
entry.name = "My Video";
entry.description = "My video";
entry.userId = userId;
entry.creatorId = userId;
entry.type = KalturaConstants.KalturaEntryType.AUTOMATIC;
entry.mediaType = KalturaConstants.KalturaMediaType.VIDEO;
entry.sourceType = KalturaConstants.KalturaSourceType.FILE;

KalturaClient.media.add(function(result){

console.log("media entry added " + JSON.stringify(result));

var resource = new Kaltura.objects.KalturaUploadedFileTokenResource();
resource.token = token.id;

KalturaClient.media.addContent(function(result2){
//if(err) console.log('Failed to add content ' + JSON.stringify(err));
console.log("media entry updated with content " + JSON.stringify(result2));
}, result.id, resource);


},entry);

},token.id,data);

}, uploadToken);
});
}
});

}

initialize(function () {
console.log('Uploading file');
uploadMedia('main_OUTPUT.tmp.mp4',1901);
});


Please help, i am new to node.js.

Thanks

Answer

I have to give path of file in string and i am giving file data in bytes. So replace "data" with string path like "/opt/video.mp4" and it works.
