Thanks, I should have known to do that.

I don't remember having to install mbuffer last time.

Last spring, I used my pi to time shift video from the camera module 30 sec for diving. It worked great!!!! This is the code I used... raspivid -t 120000 -w 1280 -h 720 -n -b 5000000 -o - | mbuffer -m 20M -P 40 | /opt/vc/src/hello_pi/hello_video/hello_video.bin /dev/stdin I misplaced the sd card and...

i have upgraded twice this week. i tried again tonight and this is what it said.... omxplayer package has been kept back. Reading package lists... Done Building dependency tree Reading state information... Done The following packages have been kept back: fake-hwclock gnome-accessibility-themes gnome...

I'm pretty new to this, so I'm not sure if I updated right. I used the directions on raspberrypi.org and I updated when I installed the camera. Thanks pi@raspberrypi ~ $ apt-cache policy omxplayer omxplayer: Installed: 0.2.6~git20130427~fcfb7911 Candidate: 0.3.6~git20150210~337004e Version table: 0....

The hello_video thing worked!!!! Thanks. I have one last stupid question to ask and it's probably the dumbest. When I put -t 0, how do I stop it? I can't use killall raspivid because the pi@raspberrypi ~$ doesn't show up. It's just a blinking curser. Thanks a ton. Here is the which omxplayer and omx...

I went ahead and did the sudo apt-get update and sudo apt-get upgrade

So, I got this...
pi@raspberrypi ~ $ omxplayer -v
/usr/bin/omxplayer.bin: invalid option -- 'v'

Thanks

Thatnks for your help. I appricate that you took the time to explain what was going on in the code. I'm still having problems, however. I think I got the raspivid stuff right, but when I run omxplayer, it says.... pi@raspberrypi ~ $ mkfifo fifo.mp4 pi@raspberrypi ~ $ raspivid -t 0 -w 1280 -h 720 -n ...

I would love to be able to shift a live feed of video 30 seconds. I coach diving and I want the divers to be able to watch their own dives. I thought I could do it by using raspivid set to infinite time and then opening up omxplayer player, but omxplayer only shows what was recorded before it was op...
