[hacker1024]

Steps To Reproduce

Steps to reproduce the behavior:

1. build and test gst-plugins-rs on Hydra

Build log

Additional context

Tests time out when building gst-plugins-rs on Hydra.
This was reported to occur on Darwin in #225143, but also occurs on Linux as well. Currently, there is no up-to-date build for aarch64-linux in cache.nixos.org.

Oof the tests timed out on aarch64 on one and livesync plugin test failed on the other. I guess I'll make that timeout longer and disabled livesync on aarch64. PR incoming in the next hour or so

This was reported to occur on Darwin in #225143, but also occurs on Linux as well.

Darwin timed out in ofborg on the PR for other reasons (ofborg's internal timeout, not the timeout I set on the tests). It successfully built on Hydra after merging and I had tested it locally

For reference, this was the test failure on livesync on aarch64:

     Running tests/livesync.rs (build/target/aarch64-unknown-linux-gnu/debug/deps/livesync-335f59c0161e7d2b)

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

I'll follow-up with the gstreamer folks later and figure out what's going on with the livesync test (more uninitialized memory usage in videotestsrc like in audiotestsrc maybe 🤔)

Oh hey it's actually already been reported upstream. I'll just disable it across all platforms then and will re-enable when that issue is resolved

I've opened #234771

Thank you for reporting! (I've been checking zh.fail every couple days, but hadn't in several days so missed the failure)
