@taichiro-ishikawa-play it seems that your url uses <BaseURL>https://example.com/</BaseURL> which is a bad url, also the mediaPresentationDuration="PT12S" is different than <Period id="0" start="PT0S" duration="PT6S">

@avelad It is does not matter of this issue. This stream does not play, it expected. Issue is Resolve init segment url using unrelated AdaptationSet BaseURL.

For example, This MPD's video/audio initialization segment use wvtt AdaptationSet BaseURL instead of MPD BaseURL. (NG) By other hand, video/audio media segment use MPD BaseURL. (OK) This behavior not occur v4.5.0, this is regression.

@avelad It is v4.5.0 playable and nightly unplayable MPD. https://taichiro-ishikawa-play.github.io/hls-sample-stream/dash_multi_baseurl2/master.mpd
