how to get only vp8 bytes

hi. the webp format is based on the vp8 codec, how can I get vp8 bytes without metadata? I have a need to create
a webm video (using https://github.com/pion/example-webrtc-applications/tree/master/save-to-webm ). On mac OC, I used another vp8 codec and the video was created, but on windows that codec does not fit, I tried your project, but the video is not being created, I think this is due to the presence of any service information in the file

Start with the issue description and the referenced save-to-webm example, then inspect how this Go WebP project exposes encoded bytes. Compare the output expected by the WebM example with the project’s output on Windows. Done requires a reproducible cause and a confirmed way to obtain compatible VP8 bytes, but the issue names no files, tests, or acceptance criteria.
