Technical summary

Streamlink DASH BaseURL handling can join segment paths against the wrong MPD manifest URL path.

Resolve MPD BaseURL values with URL joining relative to the manifest URL directory, preserving path segments.

This issue is about MPD URL path joining, so the bug shows up when the manifest is not at the domain root.

The snippet uses native project logic; the MPD URL and BaseURL node are joined before Streamlink resolves segment URLs. The helper result is consumed directly by the patched code path.

After applying the patch, keep the import smoke test for the affected package:

python3 -c "import streamlink; print('smoke test OK')"
