[jitsi-dev] Problem running jitsi-hammer

Archive

Hi!

Trying to launch jitsi-hammer, getting this:

It looks like it needs to have jnffmped library installing - but
having played a lot with ffmpeg, libav* stuff before this is the first
time i hear about it, and most mentions on the internet refer to
Jitsi.

Do you have any idea how do i build it to fix the problem?

Thanks,

Mikhail

Hi!

Trying to launch jitsi-hammer, getting this:

It looks like it needs to have jnffmped library installing - but
having played a lot with ffmpeg, libav* stuff before this is the first
time i hear about it, and most mentions on the internet refer to
Jitsi.

Do you have any idea how do i build it to fix the problem?

The hammer doesn't need ffmpeg, the warning is harmless. The other warning, however, isn't. Can you share the command that you us to launch the hammer?

Hi Boris!

Thanks for getting on that! Honestly i don't even remember how i
invoked Hammer, because not getting verified on the mailing list, i
just got this email a few hours ago, and before that, i set up load
testing the other way - running my Electron app in Xvfb inside Docker
containers - which seems to work just fine. I am facing another
problem though, on which i sent a separate post.

Trying to launch jitsi-hammer, getting this:

It looks like it needs to have jnffmped library installing - but
having played a lot with ffmpeg, libav* stuff before this is the first
time i hear about it, and most mentions on the internet refer to
Jitsi.

Do you have any idea how do i build it to fix the problem?
