Steps to reproduce

Research direction

Reproduce the HEVC/H.265 upload in the viewer and inspect the browser log, especially client.js:125 and the reported video.es.js error. Trace how the files_videoplayer app handles an unsupported format; done means the viewer gives clear feedback instead of showing a black screen with audio only.
