insert.video answered playable=true with no warning for a clip whose video codec has no decoder (a VP8 + Vorbis WebM, say): its audio track plays, but the slide shows an unexplained black box, which reads as "black with no audio". The insert now warns that the video can't be played yet and only the audio plays. The missing audio itself is not reproducible: through the real insert + play path the Vorbis track of a VP8 WebM decodes and sounds, on main and on 0.10.0 (the reporter's build). A regression test drives that whole path, on a new synthesised clip-vp8.webm fixture. Co-Authored-By: GLM-5.3 <noreply@z.ai>
