Hi,

Thanks for this script - I am trying to run it on ubuntu 13.04 but having some problems.

Here's the config:
INRES=”1280x720″ # input resolution
OUTRES=”1280x720″ # Output resolution
FPS=”25″ # target FPS
QUAL=”ultrafast”
STREAM_KEY=$(cat ~/twitch/.twitch_key)

avconv
-f x11grab -s $INRES -r “$FPS” -i :0.0
-f alsa -ac 2 -i pulse
-vcodec libx264 -s $OUTRES -preset $QUAL
-acodec libmp3lame -ar 44100 -threads 6 -qscale 3 -b 712000 -bufsize 512k
-f flv “rtmp://live.twitch.tv/app/$STREAM_KEY”

and here's the error message:
[x11grab @ 0x1215d00] Couldn't parse video size.
:0.0: Invalid argument

Do you have any idea why I am getting this error?

Best regards,
Iancul

Look like the quotes are directional quotes. Go back and retype every quotation mark and it should work.

Bumping this thread to mention that I'm having issues:

1. Terminal window runs fine and prints frame outputs but stream doesn't start
2. If stream does start (sometimes it works), I only see a green screen with static.
