Firefox's navigator.mediaCapabilities.decodingInfo costs ~14 ms per call
(out-of-process RDD decoder probe). Shaka Player calls it once per Variant
in the DASH manifest while filtering supported variants, and YouTube
manifests routinely have 1000+ variants, so player initialization stalls
15-20 s on Gecko-based browsers before the first SourceBuffer is added.
Wrap decodingInfo to delegate "supported" checks to
MediaSource.isTypeSupported (sub-ms on Firefox) with a per-MIME cache.
DRM probes and non-media-source queries fall through to native.
Wrapper is gated to Gecko UAs so Chromium and Safari are unaffected.
