[FFmpeg-user] balancing image generator and FFMPEG 'loop'

[bino at indoakses-online.com]

Dear All ...

I'm trying to get a cam snapshots and stream it out to ustream

my solution is based on two things
1. Snapshot downloader :
It's based on
https://github.com/jpmeijers/pisstvbeacon/blob/master/AircamDownload.py ,
and I make it to send request in loop.
Currently with this script, new image will be generated each second
(more/less).

Each image have a sequence number in it's name : pic01.jpg --> pic99.jpg

2. Streamer :

ffmpeg -re -loop 1 -f image2 \
    -i "/var/run/snapshots/inaxtower/pic%02d.jpg" \
    -r 10 -vcodec libx264 -pix_fmt yuv420p \
    -f flv "rtmp://1.XXX.fme.ustream.tv/ustreamVideo/XXX/USTREAM_KEY
flashver=FMLE/2.50(compatible;0FMSc/1.0)"


Currently the result looks like 'rushing'.

You can check my current result at : http://www.ustream.tv/channel/16636088
Please put attention on the clock stamp at top-left of the movie, looked
weird.

My Question is :
    How to balance image generation rate (script #1) with the ffmpeg rate ?
    I mean, what number should I put for image generation rate? ,and
    what number should I put for the value of ffmpeg '-r' ?

Sincerely
