I didnt say that I'll leave
I just dont have time Now ^_^

by the way how is the driver !!
is it good or bad !!!

No comment untill now

The pics i have taken upto now seem fine, Liking the compression on some too!

Have had 5895Kb! Insane!

What other changes have you done in this version, i can't tell with the naked eye!

From the previous driver is a big improvement on the plus, there is no longer so much noise but there are still too many shades of the blue and white

Good news,C905 support vga video recording but you'll can't watch on phone and the bitrate still the same ...
If anyone discover where's the code for video bitrate will help a lot...
I haven't tried many values,here's a sample(i no,the bitrate and framerate s**ks is just an example...)

My C905 Super-mode is completed, can anyone give me a link to C905's original en.lng so that i can edit some parameters in it for the driver?

When you said "Normal Driver", as in AUTOMATED ISO?

How do you find the current version of the cam driver?

Also would the cam driver affect how it saves the data? I'm having problems since I updated my phone (from SEUS) with it geotagging correctly, it doesn't seem to write the EXIF tags properly - and I was wondering if the cam driver might cause the problem.

luhccas you can give a link to this driver which records video in VGA?

I think this is the secound time you asked and I didnt replay
sorry sorry sorry
I 'm really so sorry

yes Normal is as the original driver
you can't fix the ISO
and effect list is effect
not like the other driver where the effect list allowe you to change the ISO

Have had 5895Kb! Insane!

you can get up to 7MB
the maximum I got was 6.7
^_^


What other changes have you done in this version, i can't tell with the naked eye!

less compress
more contrast
WB
there are some other small changes like the color, brightness, exposure just to fix the contrast issue because more contrast = less color ,brighter image

^_^


@mazi292
but there are still too many shades of the blue and white

is that while using the flash !!!
because I spends a lot of time just tring to fix this flash issue

i got one at 6008kb!!!!!!.very,very good driver but the colours are too cold,too many shades of blue,more warm colours would be more natural.as for the contrast is too high,too much white scenery,the contrast value is 01,but even if i put it to 00 it's still too much conrast.

luhccas-c905, would you mind to make a mod camdriver for C901? I have gave original camdriver in a thread where u ask for it. Sorry for being out of topic here...i've lost my patient to wait nice mod camdriver for it.

Posted by eltoffer
Thanks for the advise it was so easy how i couldnt see before :S

here you have new modded version of my driver, i was working on it its a bit improve i guess i fix the colors only all is just like the last one 3.6

it is 3.61 i also add one INTERESTING GIFT on rec mod please check it out

really with camera driver can we achieve VGA video recording?? really?? then its possible in w995 too rite??

Posted by daviep
eltoffer-does your new driver with vga video still have the qvga@30fps option?

Hi dude,i'm working on it right now ^^!
Waiting for my greenheart from ebay ...

If someone discover where is the code for video buffer c905 can handle up to 3.6mbps without any problem...
And about the bitrate i've tried 24fps and works but the low bitrate kills the quality

Im working on having both recording options

to lucas: where did you manage the FPS i can handle up the bitrate but i need to know the FPS

Use the night mode for VGA and left the normal mode in QVGA
About the fps:
BB8 = 3000 = 30 fps ,got it?

Yes,but the bitrate still in 886kbps
And for sure have repeated frames...
Where do you increase bitrate?

Posted by eltoffer
mmm could you please post a vid at 24 fps???? i cant make it record at that fps :S

There is only one minus the driver can not play the recorded file on your phone.

Posted by Luhccas-U1a
It's frimware limitation... Isn't the driver.

Posted by Theliel
I want give us a little explication:

I dont want to "criticize", but yours VGA mods are very poor. You can record video to VGA resolution, yes, but in the best case you only obtain 7-12fps, depending scene complexity. You can force to 15fps if you want, and 24 or 30, only need change a pair of numbers, but this change dont mean you obtain this framerate.

For example, the video upload by eltoffer with her 3.61 version. You can analyze the video and you can view that the máximun fps are 11 (it dont bit). Anyone dont trust me, i can post some images.

And this its very simple. The clock of this camera its setting to 13MHz (Master Clock its double, but its used for other things). But a 640*480 resolution for 15fps (for example) need a little more power. A simple example:

C905 camera capture video in YUV422/YUV420. YUV422/YUV420 need read 4bytes per output pixel (if i remember)

CLK 13MHZ similar to said that can read 13.000.000 bytes per second.

QVGA= 320*240 -> 320*240*4 = 307200 -> 13*10^6 / 307200 = 42.3fps max
VGA = 640*480 -> 640*480*4 = bla bla bla = 10.57fps max

Of course this its relative, you can obtain in some times a little more/less.

If you want a pure VGA at 15fps you need:

640*480*4*15 = 18432000 Hz = 18.5MHz aprox, 19MHz

this mean you must overclock the stock 13MHz clk to at least 19MHz. This can be done in camera driver. The problems? Its can be... dangerous. Always its possible a little margin in OC, but nobody know never the max threshold. My be 19MHz can be safe, maybe no

VGA at 15fps = 19MHz -> Must be safe and stable
VGA at 20fps = 24.5 -> 25MHz -> Can be safe and stable
VGA at 25fps = 30.7 -> 31MHz -> The most probable its very dangerous for cam integrity


In other point, this its only the first problems. Exist other: bitrate. If you want obtain a good quality you need a good bitrate (depending of course of codec). C905 take videos in MPGE-4 part 2 (Im sure that SP profile only) and h263 for videoconference only. In both cases, at a target bitrate of 768. With MPEG4 part 2 SP, 768 can be sufficient for 320*480 30fps, but for 640*480 at 15fps you obtain clearly much less quality. For 640*480 at 20 you obtain less. If you want obtain a similar quality at 640*480 at 20fps you need at least about >1.5Mbps.

Looking into camdriver maybe its possible make a mod to take video in pure YUV, so you can obtain a max quality for video recording with a "expensive" memory size

cheers.

Wow! Been on vacation for some time and what a surprise after coming back home!

Eltoffer did U make any changes with Your camdriver besides 640x480 video?
Cheers DM! nice to see U R doing great job again!

In the location of ifs / settings / camera / There are two files camdriver0 and camdriver2 (in the older firmwares, there were three if I remember correctly).
I have a question what's for camdriver2? Has something to do with the video but what exactly?

Just like you I was puzzled. So itchy fingers of me, I went to delete camdriver2.dat. Ended up when I boot my phone and try to view videos, my phone kept hanging. So I realized it might be cause I deleted it. So true enough I flash my firmware again and this time not removing camdriver2.dat but just overwriting camdriver0.dat and no hang appear when I tried to view videos.

Any news about eltoffer's 3.6.1 camdriver and fixing video playback through device??

Posted by mikely_28
Dm & Eltoffer: Did U guys tried to do something with a camdriver from R1FA035 firmware? Some people say that SE has improved it.

Posted by eltoffer
well guys i got bad news

1.- im not sure but i guess the phone will never playback vga videos

2.-certanly we can record at VGA but lately i have get some bugs (the camera closes while recording and doesnt saves the file) and only at 11-12 FPS (1.3-1.4mbps) i was trying to get more fps but the phone becomes unstable (the camera just doesnt stars, or starts but is not working)

So........

i cant clear what else should i do to improve this driver sorry guys but it is out of our limits, damn be the SE programmers

PS keep trying

With 20mhz 15fps vga are ok but qvga looks laggy...

@eltoffer

where is the iso setting for your new camdriver 3.61?
under WB, effect, or...?

Posted by eltoffer
hi it is on WB thanks

Posted by Luhccas-U1a
Why don't you try in your phone Eltoffer ?
Code:
// Camera characteristics section
//====================================================================

cam_power_on_0 = 5, 2, 113, 0, 00; // Pull CAMRESn pin (PO3=Port 9, pin 3 + 0x80), delay 0ms
cam_power_on_1 = 5, 2, 112, 1, 01; // VCAM_SD18 (PO2=Port 9, pin 2 + 0x80), delay 1ms
cam_power_on_2 = 5, 2, 110, 1, 01; // VCAM_SA28 etc (PO0=Port 9, pin 0 + 0x80) delay 1ms
cam_power_on_3 = 5, 3, 9, 4E20,14;
cam_power_on_4 = 5, 2, 113, 1, 05; // Release CAMRESn (PO3=Port 9, pin 3 + 0x80), delay 5ms

In supported sizes:
29[90,B0,3E8], // VR 144 x 176 YCbCr 10 fps
2a[140,F0,BB8], // VR 320 x 240 YCbCr 30 fps
2b[280,1E0,5DC], // VR 320 x 240 YCbCr 15 fps
2c[280,1E0,5DC], // VR 320 x 240 YCbCr 7.5 fps
2f[140,F0,BB8] // VF 320 x 240 YCbCr 30 fps

And on seq_vf_config_2*(b and c) framerate use 1E
======================================================================================
I think that "trick" isn't usefull... We can try to record in wqvga,wcif or other not-so-high resolution.
The values for change the output resolution,framerate we know.Now,need to found a value for #SET_REG(23,**) who works well with the chosen resolution...

Posted by eltoffer
i have tried but no success thats why i asked to you a video, do you really get 15 fps at vga??????

about to use other not so high res i think theres no 23,XX which controls that res i.e. wqvga i think the only res are 144*176, 128*96, 320*240 and recently discovered 640*480 any way ill be around here looking for your updates XD

Dear eltoffer,

Can you post 3.61 again? Cos when I click "http://www.megaupload.com/?d=D2IEQ5D9", I got "This service is temporarily not available from your service area."

Thank you very much.

Best Regards
Kelvin
