How to play video of "Playback on other websites has been disabled by the video owner"

[JmyW]

Is that possible to make the video work? More and more video was limited "Playback on other websites has been disabled by the video owner". I originally thought it must be common problem for all apps besides YouTube itself. But I found some apps as following that can play those videos. How do they make it work? Do you have an ideal? Possible to do so?

Have you tried playing the videos in the sample app? does it work there?

I am surprised those apps are allowed to exist on the PlayStore, as they seem to break YouTube terms of service in many ways. Also it doesn't look like they are using the IFrame player to play videos.

Yes, I tried your sample app. Those videos cannot be played.

BTW, I found a website I'm not sure whether it's same issue. She added a meta tag to fix her issue. "". It's Chinese web content, you can translate to English. Just FYI, I'm not familiar on html design, not sure what it is, hopefully not waste your time.

It seems like the solution is for the video owner to allow embeddings, see here.

I see. It's mainly about "allow embedding". Just hope to get a way to play those videos like those apps :(
