N97 Review Day 5 - Camera app crashed & Lock Switch wouldn't unlock so I did a hard reset

N97-1 camera app crash 070620098264

 

Today was a wee day of frustration (which could be attributed probably due to the early V11 firmware or less likely the the fact that I am running the 5800 i.e. unsupported version of ShoZu) in trial N97 review land:

  1. At one point, the N97 lock switch aka "keyguard" stopped working, i.e. it wouldn't unlock and the only way I could fix it was to do a *#7370# hard reset which meant I had to re-install all my apps (ShoZu, Nokia Sports Tracker, etc which was very annoying for me, imagine if a non S60 geek had to do this!)
    1. Hmmm, looks it might be fixed as follows (hat tip to The Definitive Nokia N97 Bug List):
      "Unlocking the phone via lock switch will not activate the backlight most of the time. This happens on the first unlock after an idle period – subsequent unlocks will activate the backlight until the phone goes into idle mode again. Seems to be a pretty universal problem. Extremely annoying because I have to hit the unlock switch a minimum of three times, usually more. No fix yet. Workaround: Hit the Menu Key [thanks Jasz] or Camera Key [me] to turn the backlight on before hitting the unlock key."
  2. The camera app hung as shown in the photo above in the "Processing Image" state. Holding the menu key and trying to kill the camera app didn't fix it (instead the phone just showed a blank menu of apps). I had to turn the phone off and then on to make it work.

Can't record video from S60 Python on an N93, how do I record video at 640x480?

Aaargh, it turnes out (thanks to Forum Nokia people for responding to my query!) that I can't record video from S60 Python on an N93 (see my earlier S60 video python post) without installing a MultimediaDD certificate which for some reason (bug?) is not present on an N93. Please Nokia update the N93 firmware to include he Multimedia DD certificate !

Questions:

  1. Since it's extremely unlikely there will be further N93 firmware updates, how do I install a Multimedia DD certificate on my N93?
  2. How do I get camera.start_record() to record 640x480 video on an N95? Is there some size parameter I need to specify in order to record at 640x480 resolution? There is nothing in the docs about a parameter that specifies the video resolution

 

How Do I record a Video using S60 Python 1.4.1?

I tried to record a video using the new video APIs in S60 Python 1.4.1 but I can't get it to work. My code (inspired by instaflickr code from the S60 Python Book Sample code) runs but the red light doesn't come on on my N93 and nothing is recorded. I am guessing (Forum Nokia post, SourceForge Bug Report) I have an error in camera.start_record() in the following code (which is also attached):

import appuifw
import e32, key_codes, os, os.path, camera, graphics
def cb(im):
  try:
    canvas.blit(im)
  except:
    appuifw.note(u'cb')
def cb2(im, blah):
  try:
    x = 1
  except:
    appuifw.note(u'cb2')
def start_viewfinder():
  camera.start_finder(cb)
  camera.start_record('E:\\Python\\whatever.mp4', cb2 )
  canvas = appuifw.Canvas()
  appuifw.app.body = canvas
  start_viewfinder()
  e32.ao_sleep(30) # record video for 30 seconds
  camera.stop_record()
  camera.stop_finder()

Lowepro - CompuTrekker AW backpack is what Kris and I carry all our photo, video and computer gear

My Lowepro Computrekker AW - Roland in Vancouver 1177.jpg

I know Tim has already bought a Brain Bag but if you have to carry around an SLR, a laptop, and other things (I also carry an iRiver, an iSight, 2 microphones, a zoom lens and many other technical doodads and geegaws), there is really no other alternative. It ain't stylish being all black but it does the job and it does the job well. Highly recommended.
