Yes, I did Is and it shows the files are in the folder (N900 memory).
But it doesn't want to instal them..

...too bad this already happens with the stock/unaltered 'dsp' profile from kernel-power-settings v13.

Default DSP profile is SR enabled, issue is some devices cannot handle the too low voltages which SR supplies even for stock frequencies. make sure to disable SR and tinker(by lowering voltage after disabling SR) with voltages untill you finds best stable voltages.
hopefully freemangordon will update kp50 with better SR voltages/calibrations.


Alternatively you should be still good to have SR on by moving oc-DSP frequencies to higher MPU frequencies. i.e 805: xx :560 and 850: xx :600

Too strange that it DID work for several days (around the 19th of November) before i updated to the last CSSU testing. With SR enabled. I have several 1024x576 videos recorded from that period.

Hey @<camera-ui2 devs>,

yesterday I was thinking in bed (...) is it possible to implement software zoom in videos similar to the one found in Canon's newer DSLRs.

For example if the sensor is 512x512 pixels and you are shooting video @128x128 you would be skipping 3 pixels for each one, at zoom level 2 you would start shooting from 128th pixel top&left and end at 384th pixel skipping every other pixel, and at zoom level 3 you would start from 192th pixel and end at 320th pixel, capturing every of the pixels. This will create a software fake zoom that does not lose quality.

And some illustrations(Rant @TMO file uploader requirements):
Sensor: 32x32
Image: 8x8

Yeah sure freemangordon (i mean "tecs", scusi), don't try to cheat us :D

Nah, it is not me.

Black screen / stuck on first frame on my device as well. DSP overclocked, SR off. With and without freemangordons 720p-packages.

I was having issues with camera-ui (original AND new), which nothing seemed to fix. On a whim, I decided to try the new 720p package because it contained some up-stream fixes. I figured it was already broken, so what could it hurt? Since then, camera-ui hasn't gotten the dreaded gst-faults (where when run from xterm it complains about not being able to allocate resources on dsp to save the image).

I see no reason to stay on the older drivers if they're not working for you... Give the new ones a shot. (Btw: I did discover that disabling SR vdd1 was needed to make it work properly for recording. Playback seemed to work fine in both modes though... How odd is that?)

Still withouth getting any answer...

The DSP can handle higher bitrates? ( in theory DPS isnt the limiting factor here, it looks like write speeds are too slow )

So please, tell me, is posible to increase the bitrate? videos still looking to pixelated, my old Samsung H1 run at 15mbps at HD 720P and has lower hardware ( nand/microSD speed sucks ).


So please, i need an answer, i really can sleep! xD
