Yes

Reproduction steps

1. Set the supported media types to ImaAdsLoader,setSupportedContentTypes() to be only DASH
2. Play content with VAST URL (to be supplied)

The key to the issue is:

1. The VAST MediaFiles tag indicates the mime-type, but that is not passed in the MediaItem to the player.
2. The URL has no extension so the player guesses the format incorrectly.

The VAST looks like:

<MediaFile id="GDFP" delivery="streaming" width="1280" height="720" type="application/dash+xml" minBitrate="45" maxBitrate="5343" scalable="true" maintainAspectRatio="true">
<![CDATA[ https://redirector.gvt1.com/api/manifest/dash/requiressl/yes/source/gfp_video_ads/id/d66a085f556356c8/itag/0/playlist_type/LIVE/xpc/EgVovf3BOg%3D%3D/acao/yes/mime/application%2Fdash+xml/ctier/L/ip/0.0.0.0/ipbits/0/expire/1768102093/sparams/ip,ipbits,expire,requiressl,source,id,itag,playlist_type,xpc,acao,mime,ctier/signature/851CD059CE4A127D9B9BBFC35EC94C4F98F0E4D9.0CDAC505A856B1E916226E487580BAE54D62B20F/key/ck2 ]]>
</MediaFile>

This could be impossible for ExoPlayer IMA Extension as it looks like the AdMediaInfo discards everything in the MediaFile tag except the URL.

At any rate, egregious shortcoming is something you (AndroidX/Media team) may have far more luck then we do raising to the IMA SDK (if indeed that is the problem). With no access to any of this source so I can only guess

Expected result

The ad plays correctly
