Image preview error

[fabioharry]

Thanks for sharing!

I'm working on a project that uses this feature, but when I run your solution, an error is occurring.

Has anyone managed to make it work?

Any idea how I can solve it?

Hello, awesome project.

• @fabioharry @jdelrue It works (vp8enc, webcam) on firefox 62.0
• it doesn't work on chromium 69.0.3497.81 (Official Build) Built on Ubuntu (same issue as Image preview error #3)

issue on chromium may be linked to https://bugs.chromium.org/p/chromium/issues/detail?id=469457

It also works using x11grab (on firefox 62.0) but I had to take into account my modest hardware ^^ (-framerate 5, fewer threads, lower speed...)

Setup

ffmpeg -f x11grab -framerate 5 -video_size cif -i :0  -vcodec libvpx -b:v 3500k -r 25 -crf 10 -quality realtime -speed 6 -threads 4 -an -g 25 -f webm tcp://localhost:9090
