What is a 100KB WebM file useful for?
A 100 KB WebM is the right file for testing VP9 video support in your stack. WebM is Chrome's native video format and the default output of browser-based recording APIs (MediaRecorder API). Use it to verify MIME type detection (video/webm), to test that your video player correctly handles VP9-encoded content, and to confirm your pipeline remuxes or transcodes WebM for Safari delivery (Safari does not support VP9 natively without MSE).
What's inside this file?
Generated by ffmpeg. An 854 × 480 SMPTE colour-bar test pattern approximately 12 seconds long, encoded with VP9 at CRF 33 (quality-based encoding). Audio: a 440 Hz sine tone, mono, Opus at 64 kbps, 48 kHz. WebM (Matroska subset) container with EBML header and 'webm' DocType. VP9 achieves approximately 40% better compression than H.264 at equivalent quality — this file is slightly longer than the equivalent MP4.
