dash.js player doesn't seem to work if 'Location' field in manifest file is different from the manifest download uri.

Version 4.7.4
Problem with reference online player.

dash.js player doesn't seem to work if 'Location' field in manifest file is different from the manifest download uri.

Bug seems to be located in the following method.

function getBaseURLsFromElement(node) {
var entries = node.BaseURL_asArray || [node.baseUri];

This method doesn't take manifest 'Location' field into account.

This method is called recursively on manifest nodes.

I've fixed it by replacing

var entries = node.BaseURL_asArray || [node.baseUri];
with
var entries = node.Location_asArray || node.BaseURL_asArray || [node.baseUri];

I don't know if this is the correct fix, but this may help you to solve the problem.

Can you provide a sample stream to reproduce?

Hello,

Please find attached a sample stream.

Test.zip

This is a just of modified version of https://dash.akamaized.net/akamai/bbb_30fps/bbb_30fps.mpd :

• added 'Location' section at the beginning (line 3)
• commented out 'BaseUrl' just in case (line 2)

You can see the problem:

• by copying the .zip content to a local disk (ex : D:\Test.mpd)
• by loading 'file:///D:/Test.mpd' (with correct path) in the reference player (https://reference.dashif.org/dash.js/nightly/samples/dash-if-reference-player/).

'Location' should allow to view the stream at the provided 'Location' (https://dash.akamaized.net/akamai/bbb_30fps/bbb_30fps.mpd).

Instead, the player try to read steam relatively to the manifest place (from disk).

With my modified version of your player, it works. See my first post, but I'm not sure at all this the correct fix.

Hi, dsilhavy

Did you manage to reproduce the bug with my sample ?

Thanks
