<h1>Hugging Face Space DASH test</h1>
<p>This page is meant to run from a Hugging Face Static Space and test whether a DASH manifest and its segments can be played from a Hugging Face dataset repo without cross-origin failures.</p>

<p class="small">Use a dataset URL like <code>https://huggingface.co/datasets/USERNAME/REPO/resolve/main/dash-h264/manifest.mpd</code>. If playback works here but not on your own domain, the issue is cross-origin policy rather than packaging.</p>
<p class="small">Check the browser console too. dash.js may fail because of CORS, unsupported codecs, or a segment path problem.</p>
