Support H3_DATAGRAM_DRAFT04

The latest Chromium supports H3_DATAGRAM_DRAFT04 instead of H3_DATAGRAM_DRAFT00. Handshake fails if the version doesn't match.

Question about blackhole detection and idle network detection

Hi,

I am taking tests on high sender loss network condition. The connection is often closed by the network blackhole detection. After I swiched the blackhole_detection_disabled_ to true in quic_connection.h, I got the QUIC_NETWORK_IDLE_TIMEOUT error. However, I think 5 rtos or 33ms timeout is very normal in weak network condition.

Is this normal? Could you please some hints on these problems? Thank you very much.

Execute “gn gen out/debug” command failed when compiling owt sdk on Ubuntu 18.04 system

Hi，
Seems that "gclient sync" is done.
When execute “gn gen out/debug” command
It outputs as follow:

ERROR at //testing/test.gni:21:30: Undefined identifier

Any advice about this error?

getting error at gn gen out/debug step

hello while i am trying to do the steps in build_instructions one by one at "gn gen out/debug" step I am getting the error
"ERROR Unresolved dependencies.
//:gn_all(//build/toolchain/linux:clang_x64)
needs //owt/web_transport:owt_web_transport(//build/toolchain/linux:clang_x64)"

Any idea how to make it run?
Thank you in advance.

Chromium build

Hi
Is there a way to build the owt-sdk-quic without downloading and building the entire chromium code (as it takes a very long time) . Is there still a dependency on chrome .

I saw a few quic clients online which dont need chrome.

I am reading that the new QUIC which the webtransport uses , is independent of chrome.
So assuming owt-sdk-quic uses the web transport / HTTP3/QUIC defined by IETF, do we still need to build chrome ?

thanks

Workflow fails after bumping Chromium to 93

Invalid cross-device link is reported during gclient sync. It's possibly related to container environment.

Sample Application (Linux / Windows)

Hi
Is there any sample quic/webtransport application ( linux or windows) which uses owt-client-native which calls owt-quic-sdk to
test the webtransport / quic features of owt server / client. If so can you please provide the location ?

thanks

Failed to connect to QUIC agent because of protocol version mismatch

Chrome canary now supports IETF draft 29, while server supports IETF draft 27.

Hang on destroying this from ConferenceWebTransportChannel

owt-sdk-quic/web_transport/sdk/impl/web_transport_owt_client_impl.cc

Line 76 in 5867270

task_runner_->PostTask(

When the destructor is called on the interface method that this implements from https://github.com/open-webrtc-toolkit/owt-client-native/blob/5626f534c0f5237e3a7a5303417f1eafd90f3cd2/talk/owt/sdk/conference/conferencewebtransportchannel.cc#L67 the destructor will be pended on the wait() call.

Why would the destructor need to pend on wait() if this instance will be destroyed?
