I was having some difficulty with running a Live Screencast under Linux. I've found jtvlc and tried using that, but whenever I use it the stream comes out either blank or lagged with extremely high latency. I have a fast internet connection and a fast computer, but am I perhaps taxing it too much?

Any ideas on what I could possibly be doing wrong?

# 1. Get an account on http://www.justin.tv/
# 2. Copy streaming key from: http://www.justin.tv/broadcast/adv_other
# 2. Install VLC: http://www.videolan.org/vlc/
# 3. Get Win/Mac/Lin Stream Client: \
# http://apiwiki.justin.tv/mediawiki/index.php/Linux_Broadcasting_API
# 4. Adjust the vlc parameters to your liking and run VLC like this

#!/bin/bash
cvlc screen:// --input-slave=pulse:// \
    --screen-width 1920 \
    --screen-height 1080 \
    --screen-fps 5 \
    -v input_stream \
    --sout='#duplicate{ dst="transcode{ scale=1, venc=x264{ keyint=60 }, vcodec=h264, vb=600, acodec=mp4a, ab=32, channels=2, samplerate=22050 } :rtp{dst=127.0.0.1,port=1234,sdp=file:///tmp/vlc.sdp} "}' \
    --sout-transcode-threads=4 & sleep 2

# 5. Run JTVLC to stream like this:
./jtvlc/jtvlc omnipotententity censored /tmp/vlc.sdp

# Notes:
#- If you want to see what you're about to stream add 'dst=display, '
# before 'dst="transcode['
