Chapcast adds a Podcast chapters meta box in the editor where you can enter start times and titles. On the front end, visitors see the standard HTML5 audio player plus a list of chapters; clicking a chapter jumps to that position in the audio.
<ul>
<li>Audio URL is resolved automatically: Seriously Simple Podcasting episode file, first audio file attached to the post (upload in editor), Audio block / <code>[audio]</code> shortcode in content, or a manual override / media library picker in the meta box.</li>
<li>Shortcode <code>[chapcast_player]</code> for manual placement (otherwise the player is appended after the post content when chapters exist). The legacy tag <code>[spc_player]</code> is still registered for backward compatibility.</li>
<li>Settings screen under Settings → Podcast Chapters (help text + toggle automatic player placement).</li>
<li>Media Library (list view): Chapters column on audio files shows whether chapter rows are saved on the attachment.</li>
<li>Filters for developers: <code>chapcast_post_types</code>, <code>chapcast_audio_url</code>, <code>chapcast_append_player_to_content</code>.</li>
</ul>
