This is the command that I use: ffmpeg -v 0 -y -i $OUTPUT_FILE -f mjpeg -an $HEADSHOT_DIR/$BASE_DIR/$jpg 2>&1
I run that in a bash shell script which is invoked by the flash client via remoting On 1/8/07, john_69_11 <[EMAIL PROTECTED]> wrote:

I have found that unless you are getting the FLV from a server you control you will run into crossdomain issues when trying to process it in AS. It looks like I'll be following suit and using ffmpeg as well. Do you have any suggestions/links on how to set it up? I want to process remote flvs for now and eventually using it to convert avi/other video formats to flv. Thanks for the help, -John <[EMAIL PROTECTED]> wrote: > > John, > > I don't do it in AS.
