Well I'm looking for the same thing, for a lightweight 2D game engine supporting decades old hardware (the game player is 2MB zipped, 1MB for a minimised build). Animations are likely to be low resolution and seconds long, so a huge decoding library would be pointless. Sure, most users don't care about file sizes, but some (including me) still do. Especially for the wasm and Win95 ports.

I considered libtheora, the library size is good but the compression/visual quality is awful compared to the alternatives.

Same use-case, we used to rely on system libraries but the video codec support is all over the place on each platform, and developers would test in their main platform and ship to others without fully testing and have a broken video near the end of their games because WMV runs on Windows but not on macOS, or the audio of the video was a variant of AAC that didn't run in the web port in some places and a bunch of other random differences between platforms to the point the only reliable way was to cut system video libraries and make sure all platforms have the exact same codecd. But then it turns out there isn't something better than Theora or mpg-1 without making the game player have 10x or more in size - the game player is around 3MB unzipped.

Does that hardware have the CPU power for a recent video codec? It doesn't sound like it.
