Support WebM with V9 Codec

Currently only V8 is supported which don’t bring any advantage in compression/file-size compared to MP4/H.264

Here are some requirements for Assets/Dynamic Media

  • Dynamic Media accepts WebM/VP9 video files during the asset upload process 
  • WebM/VP9 assets are automatically ingested into the Dynamic Media processing pipeline and appear in the DAM with correct metadata (resolution, frame rate, duration, codec).
  • Video Profiles in Dynamic Media include WebM/VP9 as a transcoding output format with configurable bitrate, resolution, and quality settings.
  • Dynamic Media delivers WebM/VP9 video via adaptive streaming to supported browsers, with automatic fallback to MP4/H.264 for non-compatible clients.
  • Asset processing status (pending, processing, failed, ready) is correctly reflected in the AEM DAM interface for WebM/VP9 files.
  • Published WebM/VP9 assets are delivered through the Dynamic Media CDN with proper cache headers and MIME type (video/webm).

    Interesting point about VP9 support — totally agree that sticking with VP8 doesn’t really bring much improvement over H.264 in terms of compression.

    From what I’ve seen while working on platforms like Offerix, performance and file size play a huge role in user experience, especially when media-heavy pages are involved. Having VP9 as an option could definitely help reduce load times while maintaining better quality.

    The fallback to MP4 is also important, but adding VP9 to the pipeline would make Dynamic Media much more future-ready. Curious to see if anyone has already tested a workaround for this or achieved similar optimization through other formats.
