audiocogs / opus.js Goto Github PK

Hello! My android app uses OPUS to record and play audio. OPUS is not supported on most mobile browsers such as Safari and Chrome so I gave a shot with this awesome library.
I used the prebuilt opus.js and succeeded to play opus files. However, some of my files cannot be played and I have no idea why this happens on some files. I've confirmed that these files are correct opus files using opusinfo and these files can be played on VLC player as well. I've attached links that you can download.

Whether to support opus audio frames coming from websocket, accepting frame by frame

opus.js suggests you can both encode and decode signal.

Please add encoding support. Maybe create opus-decode.js for only decoding?

i've installed av and opus.js:

"av": "^0.4.9",
"opus.js": "^0.1.1",

however when i try to play it in browser i get the following error:
