In 1.24, official GStreamer installer does not contain ASIO plugin, and MSVC is a only supported toolchan. Note that users need to install ASIO SDK and set the SDK path via build option in case of 1.24, but the dependency was removed in main branch (asio: Drop external SDK header dependency (!6404) · Merge requests · GStreamer / gstreamer · GitLab addressed the restriction but the MR and related cerbero change are not backported into 1.24)
I searched gstreamer document but there’s no asio plugin document
Documentation for the plugin is missed unfortunately (I forgot to do that). Feel free to file an issue to gitlab so that developers don’t forget about it before the 1.26 release
