Webcam / motion

[ygator]

Okay I found the problem.
Setting dinfo.do_fancy_upsampling = FALSE in the couple places they initiailize dinfo in jpegutils.c now has the colors coming out correct.

Looking into libjpeg after jpeg_create_decompress and then jpeg_read_header the do_fancy_upsampling is set to its default of TRUE.

So either libjpeg does not handle it being set to TRUE correctly or the motion program should have set it to FALSE.

Now to move on to the ffmpeg support problem.
They actually have inline assembly in the code.

Okay that was easy. All I had to do was take out the inline assembly code. It looks to be all working now.

More features then the packaged version.

Have you sorted out a PKGBUILD and patches yet? Thanks

I just downloaded the latest motion from http://www.lavrsen.dk/sources/motion-daily//motion-daily-last.tar.gz

In the file ffmpeg.c I just deleted the following lines so that it would compile under ARM.
$this->bbcode_second_pass_code('', '#ifndef __SSE_MATH__
__asm__ __volatile__ ( "emms");
#endif
')

In the file jpegutils.c after the line (there are two places) I set fancy to false as the colors were skewed without it from my JPEG cameras. Also I believe this is needed due to a bug in libjpeg not working under ARM as it seems to work under x86.
$this->bbcode_second_pass_code('', ' jpeg_read_header (&dinfo, TRUE);
')
I added the line
$this->bbcode_second_pass_code('', ' dinfo.do_fancy_upsampling = FALSE;
')

I you are already running motion do not start with your old config file as there are a lot of changes.

I already took out the emms lines, will try the others too.
But I don't hold out much hope. I don't have wrong colours at this point.

$this->bbcode_second_pass_quote('pepedog', 'B')ut I don't hold out much hope.

Just grey captures for me.

Are you able to produce an good image with fswebcam?

[pepedog]

Exactly the same.

[ygator]

I would guess problem with the camera driver then.

Here is what my camera uses.
$this->bbcode_second_pass_code('', 'gspca_zc3xx 33162 0
gspca_main 16921 1 gspca_zc3xx
videodev 63679 1 gspca_main
i2c_core 15432 1 videodev
')

hi, would you please share me how to use fswebcam? thanks very much

$this->bbcode_second_pass_quote('ygator', 'I')s anyone doing anything with a webcam?

I'd like to have a webpage I can bring up that will show the video from a webcam that is connected.
I've tried many of the webcam packages, but most don't compile due to missing linux/videodev.h.

I am able to capture snapshots with fswebcam.

Thanks
