I'am trying to upload video to Youtube with flash from browser. Usual HTML form created with official API works fine, but I need progress bar.
I'm trying to use SWFUpload, Uploadify and Yahoo UI, but all uploaders throws Security Error #2049. I guess this means crossdomain.xml file rejects my request, right?
Youtube's crossdomain.xml located in https://uploads.gdata.youtube.com/crossdomain.xml. I can see this request in browser when trying to upload. I've tested both localhost and App Engine -- same error is occured.
Could you give me a tips? Tnanks.
