What happens when you try to access the video from a browser?
ie
http://bucketname.s3.amazonaws.com/video.mp4Usually when it won't download it'll say key doesn't exist or some other message in the browser.
If your filename has spaces you'll need to encode them or double encode them with either a replacement of %2520 or %20 in the url in your xml. On a linux server I had to use %2520, on a windows server I had to use %20 - your results may vary so try a few for your situation to find what works.
Specific filenames are not supported on S3, such as a filename beginning with a hashtag/pound sign like #video.mp4, cryllic characters, spanish/german characters, ampersands (without proper encoding), etc etc.
If your encoded URL for an object on S3 is longer than 1024 characters, the file will not be able to be retrieved.
To comply with Amazon S3 requirements, bucket names:
Can contain lowercase letters, numbers, periods (.), underscores (_), and dashes (-)
Must start with a number or letter
Must be between 3 and 255 characters long
Must not be formatted as an IP address (e.g., 192.168.5.4)
To conform with DNS requirements, we recommend following these additional guidelines when creating buckets:
Bucket names should not contain underscores (_)
Bucket names should be between 3 and 63 characters long
Bucket names should not end with a dash
Bucket names cannot contain two, adjacent periods
Bucket names cannot contain dashes next to periods (e.g., "my-.bucket.com" and "my.-bucket" are invalid)
There is a maximum of 100 buckets
If you can download the file in your browser, then you'll need to examine/re-examine your roku coding to diagnose why it isn't playing.
