Able to reproduce this issue on Win-10 and Ubuntu 14.04 using chrome reported version #61.0.3163.79 and latest canary #63.0.3212.0. Issue is not seen on OS-Mac. This is a non-regression issue as it is observed from M50 old builds. Hence, marking it as untriaged to get more inputs from dev team. Thanks...!!

This is a Chromecast bug, as far as i can tell.

zivh@ - Can you take a look at this? Derek thinks it may be caused by trying to load from e.g. dev versions of the component extension that don't exist.

I am not sure what is Derek referring to. You tube does not use our bootstrap receiver, they embed it in the page. I couldn't recreate, and I am not really sure where the error come from.

I did a little bit more digging and found that the URL is generated by Chrome under certain conditions, such as when the extension requested by the page does not exist [1]. The bootstrap script tries a few extension IDs belonging to MR extension on different channels (stable, dev, etc.) in order to probe for the extension to load cast_sender.js from. Normally on Chrome this should load successfully, unless --load-media-router-component-extension is disabled, or the extension isn't loaded for other reasons (e.g., Media Router disabled by policy, or extensions is disabled). Another point is that if the MR extension needs to be downloaded for the first time / updated from CWS, then it might take a bit of time before the extension becomes available after startup. khym.chanur@: could you please check if the MR extension might be disabled due to the points above?

> Media Router disabled by policy Yeah, that's what's happened. I have set a policy to disable media router so as to remove the "Cast..." entry from the context menu.

Since MR extension is disabled, the probing logic in the bootstrap script would generate these error messages. Marking as WontFix since this is working as intended. |
