Ucview Webcam Capture

[jemimah]

Have you tried FFconvert from Shinobar?

[edoc]

Is there an option to convert AVI to AMR in FFconvert.

We couldn't find it.

CORRECTION:

My error, it wants AMV not AMR ... there is an option in wo-ff for AMR but not for AMV.

BTW: I did a conversion to AMR but it is identified in Puppy as a text file ... though that could be a mis-ID.

[edoc]

I found this page of AMV sample files but the MP4 player that will only play AMV files says that the file format is wrong.

http://samples.mplayerhq.hu/amv/

Can someone test them on a known-good MP4 player that handles AMV and tell me if they are OK?

I need to know if this is just another piece of cheap Chinese fake-MP4 junk hardware that needs to be returned or if something else is going on with more than one AMV file format out there.

Sigh.

I rebuilt ucview with the newest libtheora and now theora encoding doesn't crash. Yay! Updates coming for Puppeee and Fluppy.

[abushcrafter]

Yay ! Could you also build it for other puppy's please.

[jemimah]

Which Puppies?

Surely there's a UCview package in the Ubuntu repo that would work with LuPu?

[abushcrafter]

I was think of a generic build that would work of 4.3.* or newer. How ever I can't test it until I get my non UVC logitech quick cam express webcam working. Then there's the though of that am am considering using Fluppy as a base for my system...

nice, many thanks!

Example video, grabbed with 1 frame every 5 seconds, then encoded with 25 fps (resulting in 125* speed):

using a subfolder called "1" to store the jpg frames:


grab.sh

Code: Select all

#!/bin/bash


thedir=1

while [ 1 ];do


 ffmpeg  -y -f video4linux2 -s 960x720 -r 1 -t 1 -i /dev/video $thedir/`date +%s`.jpg

# ffmpeg  -y -f video4linux2 -s 1280x960 -r 1 -t 1 -i /dev/video $thedir/`date +%s`.jpg

 sleep 5

done

encode.sh

Code: Select all

#!/bin/bash

thedir=1



#-vf eq2=gamma:contrast:brightness:saturation
#where gamma 0.1 - 10 (default 1.0), contrast -2 − 2 (default 1.0), brightnes -1 - 1 (default 0.0),
#saturation 0 − 3 (default 1.0),

#res="w=640:h=480"
res="w=960:h=720"


mencoder-mt mf://$thedir/*.jpg -mf $res:fps=25:type=jpg -ovc lavc \
    -vf eq2=1.4:1.2:0.0:1.5 \
    -lavcopts vcodec=mpeg4:mbd=2:trell -oac copy -o output-$thedir.avi

To encode I used this mencoder:

Hello greengeek

Does anyone have a copy of the ucview pet please?
Jemimah - please come home. There is much to do.

After a quick search, it appears that the missing package from page 1 is/was unicap-0.9.5-i486.pet
you can grab a copy from here: http://akita.scottjarvis.com/

Hope that helps.

Many thanks Musher

Musher? Why did I call you musher?? Sorry CatDude!! I get you confused with musher sometimes because you are both so helpful and your avatars look a little bit similar.
