If this is the key reason for the stuttering, then there has to be a reasonable solution for it. Still, what a shame.

It's apparently not that simple.
In the case of the Media Player, the request to open the source code was denied: https://bugs.maemo.org/show_bug.cgi?id=1235

However, in this case we are dealing with a feature advertised everywhere in Nokia's PR about this phone, the supposed "dvd-quality" of the video camera. I don't know whether the solution is to open source the code or to push Nokia to resume work on this.

My suggestion would be that people keep voting the related bug:
https://bugs.maemo.org/show_bug.cgi?id=7062 adding useful technical comments when appropriate (it's a bug report, not a forum). Previous contributions to the bug report clearly indicated the developers' endorsing of the problem, until the WONTFIX.

At the end of the day, this is not even a matter of capturing video at 720p. This is a matter of capturing video properly, without stuttering, at whatever resolution the developers agree is feasible.

If others have more concrete suggestions, please share them.

maybe it would be required to run a less hogging OS to produce video without frameskipping. it would be nice to have a dualboot OS with no background tasks thats explicitly focus on the task perfomed atm.

like a Media OS with no phone features at all - which instead would include playback / recording softwares for media and camera.


btw... omnia hd actually didnt record buttersmooth 720p... i think it "averaged" at around 20fps, and there was apparent frameskipping. also sound quality was something extremely low. maybe 8khz or something like that.



shadowjk:

alright... there may be something that ive been missing here, but i know for sure that ive seen very old digital cameras handle super high quality MJPEG recording realtime in 640x480 30fps (much higher quality than N900's 800x480... not related to the lens/cmos sensor, but software - with that i mean typical encoding artefacts like blockiness and sacrificing less details)

i hope that the DSP can provide the required horsepower to enable this.

stop trolling us

it makes no difference.

You may install this very good front end for tracker:

It will allow you to test all those tracker settings.

Surprisingly, I dont have much, if any at all, stutter while recording videos. But, in my case the video-nokia_n900.mp4-stutters a bit at times while playing with the default media player.What makes this hard to tolerate for me is that this video is included by default and is the phones feature video(showing the phone features, i think)... I expected a bit more from my $500 device.

Has anyone tested this in the context of the problem discussed here?

That's what I used to test my smooth video. Works OK, though if you want you can edit the conf yourself. I have a backup. Also, the app has a "restore" that dumps the original conf in there.

Nice app.

Andre Klapper suggested that the best way to follow up on this is directly with Nokia Customer Care.

While it's great that the community tries fixing the problem independently, I think that as Nokia users we need to push them to accountability on issues such as this, especially given their claims and marketing regarding the N900 video capabilities.

To this end, I have sent them an email asking them to reconsider their decision not to fix this, and started a thread on the Nokia forum on the same. If others following this thread have a minute to spare, it would be great if they could also (politely) make their voice heard by Nokia on this. If you want to comment on my message or copy & paste some of it for your own email to Customer Care, you can find it here:

Pan test nr 1

Pan test nr 2

Nr 1 is on the EMMC

Nr 2 is saved on the SD, which is smooth for about 30 secs or so, then skips a little every 30 seconds, assumingly speed is a limiter.

My benchmarks over mass storage are as follow:

EMMC:
Unbuffered Write: 12/14.7/14.2 M/s (Min/Max/Avg)
Unbuffered Read: 9/9.57/9.4 M/s (Min/Max/Avg)

SD:
Unbuffered Write: 8.2/8.25/8.22 M/s (Min/Max/Avg)
Unbuffered Read: 8.12/8.25/8.20 M/s (Min/Max/Avg)

Benchmark software is my own home brew, using Windows single-thread unbuffered read. I'd link you, but I'm having a little trouble with my provider page, it seems to be under maintenance.
