Try some that I made up
on the fast cars thread

Many of these were transcoded from FLVs
My videos definitely have a lower resolution than 800x480 otherwise, as mentioned, they would not play. The quality is close but not quite DVD quality.
The Vivo videos on YouTube are the kind of quality I'm reffering to. Does anyone agree with me that it is reasonable to think that N900 should be able to handle that?

it may also be down to the player you are using and not the N900s capabilities-try a dedicated player if there is one for the files you want to play, or try kmplayer. you could also wait for the official release of vlc player, which should be able to handle almost all video files, and give an indication of whether the N900 is really up to the job or not. the N900s built in player seems to jump/skip with some videos that work fine on a pc, although strangely it does not seem to always be a high bitrate or high resolution issue with all types of video

If you want smooth playback you have to transcode videos if they aren't in right format for standard player. It plays videos with DSP and more optimized for ARM while mplayer plays all with CPU. I use MPEG4 and MP3 codecs and avi or mkv containers. 800x450@25 fps and 3Mbit/s plays fine. I think you don't need better quality for this screen.
I played a 192Kb/s MP3 song with standard player and CPU load was about 40% @250MHz. Mplayer did the same with 70% @500MHz (through pulseaudio). And note that N900 don't use DSP for audio. All of this is just low level optimization for particular CPU.

I have a great deal of movie backups in from avi, xvid for SD video and some h264 with AAC sound for HD. SD files are all various resolutions, none over 720x480 (DVD) moderate bitrates (1500 Kbits max. I think). My N900 plays them no problem. Just copy and paste o.O for the HD part, I am using format factory (free) to recompress to .mp4, resize from 1920:1080 to the screen resolution of 800:480. bitrate usually down to 2000Kbits. I am talking stock N900 here.

I do not run anything else in the background while playing videos.
I have checked the CPU usage when videos are playing and it runs at 100% almost constantly until I stop the video and then it drops down to less than 5%
I have managed to play some videos smoothly but it's almost always the low quality videos. The videos that I really want to play almost always have video / audio sync issues.

I'll address the other question when back on a PC. Most likely the resolution is too high though. My avi's are dvd rips.

Is there a simple way to check the details of my videos to find out if they are within a reasonable resolution and bit rate? The specific files I want to play on my N900 are flv files and I don't know where to see the info in question.

To get the facts straight:
1. Forget MHz/GHz. In the 21st century it is an almost completely meaningless indicator due to differences in processor architectures. Forget it. Really.
2. Only the built-in media player uses hardware acceleration. If you don't play it in that, it's not accelerated (=it's slow).
3. Flash will gain acceleration in 10.1 when it gets released for ARM.

BTW, 600MHz P3 is much faster than 600MHz Cortex A8 for general compute.
