Hello, this time I have some poblems with the camera:
I don't take videos often but since some time they have big squares or artifacts above movings items, regardless of the video resolution, the videos that I taked before PR1.2 don't have this problem and seem to have better quality (higher bitrate ? )
First, I tought that it was the problem was overclocking (with Titan kernel) but before PR1.2 my N900 was also overclocked at 1ghz and I has no problems and I also tried set default CPU configuration as default, power off, power on then take a video: same problem.
So what could be the problem ? Hardware damage ? I have no problem with any other application. Playing videos with Hardware acceleration or playing openglES games cause no problem.
Does anyone have this problem, or have a idea for this issue ?

Hmm this happens when I upload videos to facebook.

I haven't uploaded videos to facebook so I don't know if the N900 reencode the video before sending it. That could be the problem or it can be also a network error.

1.2 video recording is choppier than with 1.1. I have made quite many videos in low light before and after pr1.2 update.... less tearing in 1.1.
I got somewhat better recording when slightly overclocking to 700mhz

I used to see rectangle artifacting on videos taken by N900, when I viewed them on my desktop or with MPlayer on N900.

After I upgraded MPlayer on my desktop, the problem went away.

The builtin media player on N900 also played and continues to play the videos fine.

Ok sorry guys, the problem was in fact mplayer. It look like that osso-media-server (default player) handle better the frame drops than mplayer, the artifacts on mplayer are framedrops on the default media player, can some of you try play some of your recorded vido for confirming this ?In terminal:
mplayer -fs MyDocs/DCIM/*.mp4
arrows to fast forward, spacebar to stop/start, q to quit
But still, this is unacceptable that the N900 can't record 848x480@25fps videos without framedropping while devices with nearly same hardware can record HD videos without problem.
And I still don't see why 848x400 resolution is used, yes it is 16:9 but 800x480 seem more logic (screen resolution)

same problem (artifacts) both on my desktop (mplayer) and when sharing the clips online.

which version of mplayer are you using now?

The git or svn version as of 2 months ago

I also get this when I'm using Windows Movie Maker. Any suggestions?
