After trying to find elsewhere and not finding here it goes.

Is there an easy soft for recording with the webcam (how). So far it works with ffmpeg but I would like mplayer or something to watch and record at the same time like Kaffeine. I can get pics with camcoder but get error when trying to make video (no mencoder). I am using Slackware 14.1. 

Thanks for help.
 
Could you please post the exact error you get, along with pndrun_camcoder.out file?

PS. recording video with live perview never worked in camcoder. It is implemented (select the first entry in the menu, press 'v' when preview shows up), but it never worked on my system.

If i remember completely. Using the panda operatyng system(whatever it was callez) and a microsoft webcam it worked with Mplayer
 
Guvcview is working so far but gets only 9fps at 1.2 Ghz.

Mplayer is told to work for recording but how ? To view just use mplayer tv://

The error in camcoder is : could not start mencoder

Return code is : 10
 
 
You should be able to add the -dumpstream option to mplayer. I think. Maybe. If you don't have a chance to do it I'll try it tonight myself.
 
I used dumpstream but it didn't work. There is also dumpvideo option and something is saved but gives black video and big file. Maybe I miss some options.
 
Hmmm, haven't figured out an easy way to display and record at the same time yet, but I was able to record with mencoder, just needed to install it first.

# opkg install mencoder

$ mencoder tv:// -tv driver=v4l2:width=320:height=240 -o test.wav -ovc copy
 
I tried mencoder in SZ and it worked but most times I use Slackware and it seems there is no mencoder. In SZ codecs are installed but camcoder got the same error when trying to record from webcam.
