Re: Why can't N900 play videos smoothly?
 

Hah, what I just found, guys...

I read the visN900 post and I decided set new overclock profile for my tablet which is from 500Mhz to 900Mhz. Every video that I`m trying to play works perfectly!

But when I change profile to 250-900, half of my videos does not want to play smoothly...

I have only one explaintaion. Our N900 trying to be economical and didn`t set right lowest frequency for played movie.

Try this on your tablets and tell how it works:

Have fun!

Re: Why can't N900 play videos smoothly?
 

Try to play 720p high bitrate mp4 streams and see what happens. If you were having problems due to low frequency, you might want to try to get lower bitrate videos instead of increasing your low working frequency. I bet you will see no appreciable quality difference by using the more processor intensive videos, but your battery will run out much faster and your N900 will probably run warmer too.

25 degrees now, when playing video never gets over 35, so I believe it`s ok. I will stay with better overclock profile, because I like comfort. I don't like to convert video everytime I want to watch something on n900. I would like to copy it, or download from web and watch at sight.

Also I'm spending a lot of time outside, because of the work which including long breaks and waiting time. I'm connecting my tablet to free wi-fi or GSM internet, download something and I can watch it without any doubts.

Battery isn`t a problem. I have car charger, mobile charger (2800mah) and second, fully charged battery :)

In that case, I agree with you. Whatever works better!

Talking of which, I got my first spontaneous reboot today :o

My N900 is overclocked only to 805 Mhz, but it was very hot inside the car (around 100 F) and I keep it in an aluminum case which conducts heat very well. So I suppose it was very hot.

My Phone Gets Too Hot While Watching Music Videos And Then Ting Tong "Battery Low", I Think There is Nothing Exact Solution For Video Playing For Nokia N900, Cuz I Think Its All Like "Beta" Damn

Reflash it go to 720p thread follow it.
Thats it !
100% n900 leveraged to video capablites.)

Re: Why can't N900 play videos smoothly?
 

Yeah, thats great. After few days of better working problem appeared again. I did not install new apps. Now can't get any better idea over changing my phone... :/

(Edit)

Now I'm confused. I just removed "Advanced Clock Plugin" and problem disappear. I'm confused because I checked my N900 few times with this app installed and videos worked ok...
I will install it again an check this out...

(Edit 2)

Ok, first check shows that the Clock plugin caused this problem. I will test my N900 for next few days and we will see.

(Edit 3)

I just checked my dad n900 with installed "Advanced Clock Plugin" and his tablet was able to play the same video nice, with small issue (Sometimes video runs slower than it should) but it's hard to see. Uninstalling the Advanced Clock does not change antything.
I think it's time to clarify this. N900 is not tablet for watching videos, if you need phone for watching videos n900 is not the one you're looking for.

Re: Why can't N900 play videos smoothly?
 

I am unsure of a diagnosis but if you are running the 720p modded libs know that the DSP can experience voltage issues and need a reboot in order to reset. I generally have to reboot after a day or two and even within a day if I am watching vids intensively. I fact, I believe the advice for watching HD was to fresh boot.

Prolly of no use to you but...

Reflash the damm thing you have messed it up.:)
i bet n900 videos an similar are less strainy for the eyes than the amoled os similar types:)

Re: Why can't N900 play videos smoothly?
 

I am having a similar issue. I have 2 N900s, and playing the exact same file from kmplayer (using mplayer) in one of them produces a smooth video, whereas the other plays with a peculiar "sine-wave-like" playback where playback slows down cyclically every 1 or 2 seconds, then speeds up, then slows down, etc. Very annoying.

Here's my observations so far:
- Different hardware revisions (smooth playback is 2204, other one is 2104).
- Different kernel and firmware (smooth is PR1.3.1 with stock kernel, weird playback is CSSU-Thumb with KP 52).
- Same kmplayer and mplayer versions.
- In system with weird playback, playing from mplayer in the terminal produces smooth playback. I couldn't find any kmplayer options that may be affecting this. /home/user/.kmplayer only has the xml file which holds the list of recent videos.

Right now I'm copying the file to the eMMC in both systems (it's in micro SD storage at the moment) to see if it makes any difference.
