bad frames in grabber causing led flickering

[pete111]

Hello please one question, my easycap dc60 (stk1160, raspberry pi) is showing this video with "bad" frames - artefacts: http://www.youtube.com/watch?v=gRsONZBXIdw&feature=youtu.be

I tried: /usr/bin/mplayer -tv driver=v4l2:width=72:height=58:device=/dev/video0:fps=30 -vo sdl tv:// /dev/null 2>&1 &

This one was too slow for me with slow motion picture and so my leds were about 1s slower than video. (sometimes with artefatcs as well) /usr/bin/mplayer -tv driver=v4l2:width=72:height=58:device=/dev/video0 -vo fbdev -fs -fps 15 tv:// /dev/null 2>&1 &

How can I get clear video without bad frames? Because with "bad frames" my leds are flickering on "bad" frames and it disturbs me when watching video.

Have you tried overclocking the pi and see if that helps?

stozze, thank you! with overclocked raspi it is much better. :)

Hi,

I'm having the same problem but cant seem to get mplayer working to see if its the video input. Do you have info on how you did this? I have already over clocked my PI.

Thanks Luke

Hi @lukefoster197 I assume when you see video your mplayer is working. You can find out if the problem is video input when you directly connect it to your display/tv. Or second way - I connected output from raspi directly to my display (hdmi output from raspi) - to see what's happening. Hope it helps.

Hi Pete, No mate, the help I need is how to get mplayer installed and working so I can see the video on the PI? The Pi is all connected up correctly. Luke

Please, open terminal and try something like: sudo /usr/bin/mplayer -tv driver=v4l2:width=72:height=58:device=/dev/video0:fps=30 -vo sdl tv:// or adjust settings according to your settings. (I forgot if sudo and /usr/bin/ is necessary, just try with/without it ) if you need to install mplayer try: sudo apt-get install mplayer
