@BruceChai-SM Works in general, yes, using the code published, except for the unmerged PR that fixes reading bidirectional stream https://github.com/GoogleChrome/samples/pull/752. I have not achieved the requirement of live-streaming media https://github.com/GoogleChrome/samples/issues/756. The stream and datagram eventual grow in internal buffer size (should not be buffered at all), and stops streaming.

Can you share the link to the PR please?

@Niek Yes, that code runs, though does not support live-streaming. I also do not gather why Chromium authors who updated WebTransport in GoogleChrome/samples did not update code in the main dependency. I mentioned this handshake error in a PR there.

Thanks, @guest271314 Can you share the link to the PR please?
