fswebcam - gd-jpeg: JPEG library reports unrecoverable error

[drhitchcock]

Howdy Raspbians,

I recently set-up my Raspberry Pi running Raspbian to work as a time-lapse camera taking images of my tomatoe plant I followed the instructions here: http://www.makeuseof.com/tag/how-to-cap ... sb-webcam/

It's been working fine for about 4 or 5 days and then after a recent reboot I started getting this error:

gd-jpeg: JPEG library reports unrecoverable error: Not a JPEG file: starts with 0xff 0x80
All that appears in the image is a black box.

I've updated all packages and drivers, unplugged any unnecessary peripherals and I have also tried using the web cam via a powered hub. It was working via the same USB hub before I started having problems.

Any help with this would be super!

Cheers,
Dr Hitchcock

same problem here please help

[rajbadri]

it seems that the webcam was not recieving enough power. so probably a powered hub would do the trick. I plugged another webcam and it's working fine..

Hello,
I have Creative Live! Cam Notebook VF0470, which I have connected to HUB with external power supply. I have also problem. I took picture and I have it black.

This code doesn't work:

Code: Select all

fswebcam -p YUYV -d /dev/video0 -r 640x480 $DIR/$filename

I have message stat: No such file or directory

I have installed also in Raspberry Pi guvcview for webcam grafic configuration. But all the time I have black window. I have installed guvcview in Ubuntu 12.04 and VF0470 work good.

Any help with this would be great!

Hi,
I got rid of the 'gd-jpeg: JPEG library reports unrecoverable error' by adding a -S 2
This lets fswebcam skip two frames.
Seems that my camera generates faulty frames?

Code: Select all

sudo fswebcam -d /dev/video0 -r 320x240 -S 2

Fixed

I had the same problem, I found that it was actually a problem with the module and when i used zbar to scan an image the input came through fine,
Hope this helps

I have the same problem too. Mjpg-streamer, fswebcam don't run well. I think, it is a encoding problem.

Hey everyone,
I think I got the solution!
i found the instructions:

Code: Select all

sudo apt-get install libjpeg8-dev

sudo apt-get install imagemagick

and the problem was fixed.

Is it possible to save 2 image.jpg when running fswebcam? as example, when running fswebcam once, i want image1.jpg and image2.jpg saved in a folder (of course both are the same image).


>>>import os
>>> import datetime
>>> os.system ("sudo fswebcam /var/image1.jpg")
>>>os.system("exit")

above fswebcam -p YUYV and fswebcam -S 3 kind of worked for initial question, error went away but had saturated (white) picture. Increasing the -S solved the saturation problem, finally using: fswebcam -d /dev/video0 -S 30 -F 5 tst.jpg

Below command worked for me :
fswebcam -d /dev/video0 -r 1920x1080 -S 30 -F 5 image10.jpg
