Java – ffmpeg for screenshots?

So I have an applet that captures the screen and makes sound from the microphone of the computer,

How to use ffmpeg to multiplex frame by frame and then send the multiplexed output to wowza media server?

If it can't be done with ffmpeg, can you provide any suggestions?

Solution

Which OS? Under Linux, you may need to consider http://kde-apps.org/content/show.php/FDesktopRecorder?content=147844

The core of the script is:

Record screen:

ffmpeg -f alsa -ac 2 -i pulse -f x11grab -r 30 -s $(xwininfo -root | \
  grep 'geometry' | awk '{print $2;}') -i :0.0 -acodec flac -vcodec libx264 \
  -vpre lossless_ultrafast -threads 0 -y output.mkv

Record a window:

#!/bin/sh INFO=$(xwininfo -frame) WIN_GEO=$(echo $INFO | \
  grep -oEe 'geometry [0-9]+x[0-9]+' | \
  grep -oEe '[0-9]+x[0-9]+')WIN_XY=$(echo $INFO | \
  grep -oEe 'Corners:\s+\+[0-9]+\+[0-9]+' | grep -oEe '[0-9]+\+[0-9]+' | \
  sed -e 's/\+/,/' ) ffmpeg -f alsa -ac 2 -i pulse -f x11grab -r 30 \
  -s $WIN_GEO -i :0.0+$WIN_XY -acodec flac -vcodec libx264 \
  -vpre lossless_ultrafast -threads 0 -y output-single.mkv
