If you there is any library you would like to add:

• If it already exists in the replies, simply give an emoji to upvote
• If it doesn't exist, you can reply this issue to propose.

I will check this issue periodically to decide which library to integrate next, or identify which is NOT possible to integrate at the moment.

Hi guys! First off, awesome work on the project! Love it a lot. I was wondering if it would be possible for SVG rendering support through librsvg or resvg. Thanks!

could do with mutiple variations based on different tasks to save bandwidth and store the wasm's on a storage service for people to use.

@jeromewu You should update aac (fdk-aac) in the OP to aac as it seems like ffmpeg.wasm doesn't support libfdk_aac.

[fenicento]

Is there an updated / reliable list of supported formats and codecs for the latest release? Shouldn't this be in the README / FAQ?
