Thanks for your report!

Yeah, looks like the extractor is only reporting an audio track.

In BoxParser.parseStsd we check the childAtomType which in case of the skipped track has a value of 0x68323633 while Mp4Box.TYPE_H263 is 0x48323633. So the extractor doesn't recognize the H.263 video track.

When I add the following in BoxParser.parseStsd I can see the presentation of a design brand intro.

          || childAtomType == Mp4Box.TYPE_s263
          || childAtomType == 0x68323633
          || childAtomType == Mp4Box.TYPE_H263

I'm adding extractor experts who know platform and Media3 extractor code.

Hi @MrBoe,

Thanks for flagging this! We’ve added a fix that’ll be in our next rc release.
