Has issue when encoder is QTmuxingAppLibWebM-0.0.1

Noitidart commented 8 years ago

I use webrtc to record audio and video. I then use this to convert. If the recording has no idea it works fine (if I remove _madvise).

With and without _madvise though, if the recording has audio it keeps telling me Error opening filters!

I forked your repo and changed the input.webm file to cant gif.webm here - http://noitforks.github.io/videoconverter.js/demo/

Clicking the "Convert to mp4" will give you this full error:

Can you please advise on how to fix this?

Apparently it seems an older version of fffmpeg is in use by videoconverter.js - which doesn't yet fully support webm -

I was wondering if you had any plans to update :)

I'm not planning to, but I'd be happy to accept a PR with an updated version

Aw dang. Thanks for the comment. Are there instructions on how to update? I would like to try if possible.

bgrins commented 7 years ago

Thanks, that would be great! Apparently there's an issue with the version of emscripten currently used here in which we are stuck on an older ffmpeg https://github.com/bgrins/videoconverter.js/pull/30#issuecomment-98157138. What would be super helpful is if you could try pulling down the code in #30 and see if you can get a build working from that
