Converting Gif to WebM creates a corrupted video about videoconverter.js HOT 7 OPEN

Yes, I think there is something messed up with VP8 - I've tried changing a bunch of different options when compiling but never been able to get it to unscramble. As a workaround I think you could use: -c:v libvpx-vp9, but this will use the VP9 codec. I don't have any real pointers - but if you want to try to build it yourself using this script or a variation of it: https://github.com/bgrins/videoconverter.js/blob/master/build/build_all_codecs.sh maybe it will work - I'd love to see if you get different results.

For another example, run the demo app with:

-t 3 -i input.webm -vf showinfo -strict -2 output.webm

Notice that it's scrambled. But if you run with:

-t 3 -i input.webm -vf showinfo -strict -2 -c:v libvpx-vp9 output.webm

it works fine.

The vp9 codex works great, although it's a bit slow compared to other conversions -- including the broken vp8. I'm going to take a crack at building it; I'll let you know how it goes. In the meantime, thanks for your help.

maybe this one can work better, I used it to convert mp4 to webM and between http://www.bigasoft.com/articles/convert-vp9-webm-to-mp4.html

Using latest libvpx and ffmpeg in PR #30, vp8 encoder works fine for me. @DawsonG can you test it?

Sure, I've been using vp9 successfully for awhile, but I'll fire it up and see.

@duanyao I ran into problems completing the build process that I don't want to take the time to fix. Would you mind updating the pre-built .js files in your repo? I'll use those and tell you how it goes.

I created a release that you can use:
https://github.com/duanyao/videoconverter.js/releases/download/v0.2/ffmpeg_js-v0.2.zip

P.S. what are the problems you encountered? You need very recent emscripten (1.32.x) and run pull_source.sh and build.sh in build_edge.
