FWIW, I closed Bug 1676902 as worksforme because that particular test of `video/webm; codecs=vp8` was now fast. But I didn't have my thinking hat on - it was an example from a larger enumeration test of video and audio for fingerprinting - so not all codecs may have improved over the years and indeed `'video/mp4; codecs="avc1.640028"'` didn't move in the `PoC 1676902` (note you need to remove the blank dimensions size since that's invalid in FF149+) ``` this PoC PoC 1676902 webm vp8 PoC 1676902 mp4 avc1.640028 chrome148 cold: 3.80 ms 4.799999952316284 ms 5.100000023841858 ms uncached: 0.16 ms/call (N=30) cached: 0.11 ms/call (N=30) nightly153 cold: 11.75 ms 10.21100000000024 ms 234.45400000000154 ms uncached: 2.81 ms/call (N=30) 3.3997999999992317 ms rerun 220.85879999998724 ms rerun cached: 2.31 ms/call (N=30) FF102 cold: 10.37 ms 72.41029999999955 ms 220.14689999999973 ms uncached: 2.75 ms/call (N=30) 49.83520000000135 ms rerun 201.61880000000383 ms rerun cached: 2.38 ms/call (N=30) FF95 cold: 43.09 ms 99.30589999999938 ms 268.40469999999914 ms uncached: 2.53 ms/call (N=30) 80.84870000000228 ms rerun 233.44219999999768 ms rerun cached: 2.79 ms/call (N=30) ``` Perhaps we should create a new issue to test all audio/video codecs combos vs chrome for possible perf improvements
