Media Router not working for Chromium

[Shanfeng Cheng]

After updating to Chromium 55, I found the Media Router (Chrome Cast) still doesn't work for Chromium. When I click the Cast menu, it always shows no cast destination found. Did I do something wrong? Or Chromium is not going to be supported as far as Media router is concernced?

The new Chrome Media Router presently relies on a binary-only component extension, so isn't available in Chromium by default.

You can enable it in Chromium builds by running with --load-media-router-component-extension, which will cause Chromium to download the component extension.

I launched Chromium with that switch but it still can't find any cast destination. I checked the extensions folder within the user profile and no cast extension is downloaded.

Actually, I found a few other lines in the code which is masked with GOOGLE_CHROME_BUILD. After I uncomment those conditions, media router works just fine. Thanks for pointing me in the right direction.

Cool to hear you got the media router to work from chromium!

Do I understand correctly that this requires a recompile? I'd like to get back the possibility to cast :) - and that did seem to be the intention behind https://bugs.chromium.org/p/chromium/issues/detail?id=646170 which added that flag.

If you have a recent enough Chromium build (end of October 2016), you
should be able to use the "--load-media-router-component-extension"
command line flag. If you are building your own version of Chromium,
make sure this commit is applied:
https://chromium.googlesource.com/chromium/src.git/+/ac0030f5d07e66752b93695bc373bcb55ab26602
