I actually made a version of motion without ffmpeg built in becaues it did make much sense to bring in all those ffmpeg dependencies for somthing it wont use....

You do realize which forums you're on...right?

[reinaldoaf]

yes but, it is only place I found with correctly informations,

sorry for this, and sorry my english,

I read hundreds of other forums and tutorials, most aimed at linux not arm, and unsuccessfully, on of you can run the program and it gives me a screen shot, no longer generates the video stream.

with informations on another posts and this post I make one run, no correctly but run...

really sorry for that.

tks

$this->bbcode_second_pass_quote('hydro', 'T')he webcam worked fine with motion on my dockstar, but since a few weeks I have similar problems. My workaround is to first capture a single dummy picture using fswebcam before starting motion.

fswebcam -r 320x240 -d /dev/video0 -v /dev/null
