[bug] macOS audio bug with .webm

[0PandaDEV]

Describe the bug

Im working on a app with Tauri so far so good on windows everything works as expected but on macOS i can not play any files it alwasy gives me a error that the operation is not supported. I can confirm its only when using webm i tried it with mp3 too and that worked without any problems.

Reproduction

• Clone Vleer on a macOS machine
• install all the dependencies
• run the app in dev mode
• download a song through the search page
• look into the browser console (right click inspect element)

Expected behavior

It should play normally like on windows

It looks like WKWebView and Safari do not support this type of .webm (audio only?). I just tried using Safari to play the .webm file that was downloaded from Vleer, but it shows no support.

[0PandaDEV]

Exactly that is what i also observed so is there a workaround or do we have to wait for apple to „fix“ this issue?

[pewsheen]

Unfortunately yes. But there could still be some workarounds like converting the webm to another format that webview currently supports by Rust or Javascript.
