Simply put, I want access to the pause button when playing a transcoded stream.
I have gotten transcoding to work with rev1577. Using the ffmpeg sh script to play to a fifo I was successfully able to pause and restart the video through:
kill -STOP pid
kill -CONT pid
So, in theory it's possible to have a pause feature using an external transcoder.
p.s. I'm on OSX (PPC) 10.4. But, I checked out OpenBSD's man page and found the same signals are present using the same names. So, I image that there are only possibly minor naming variations across the *BSD's and Linux (Windows unknown).
