Divx movies on n800
 
I have an Axim which I use mostly for watching DIVX movies. My Axim 51v plays them perfectly without any conversion. Now I’m thinking about buying an n800 and wondering if it can play divx movies at full resolution without any time consuming conversion?

Depends on the bitrate and resolution of the DivX you want to play.

< 400x240 plays without problem at the moment in mplayer, 640x380 is maybe possible according to ssvb with further N800 optimisations.

Maybe somebody can try, let's say, play divx at 25 fps 512*208 pixels 24 bit video and 128 kbps audio (or smth close to this resolution)? What's about full vga? Is it watchable?
I just need to know, before i buy it...

N800 should be able to process up to vga resolution in full fps if I'm not mistaken.

I'm pretty sure mplayer will be able to handle pretty much any non hd movie you try.

it sounds like i've found replacement for my axim:)

I hate to bring this disappointing news, but the n800 is currently not capable of playing vga videos at a useful speed. The nokia media player runs at about one frame per second and mplayer is slightly slower. This disappointed me, since I thought it would. The processor has video acceleration capable of playing vga resolution at 30 fps. Apperantly, the video acceleration is not used. :(

I don't have n800 to test it, so any feedback and benchmarks are welcome as they help to identify and fix problems. While it is quite possible that mplayer is not capable to play that video, please make sure that you used the latest test version of mplayer built for n800: http://www.internettablettalk.com/fo...&postcount=275

If it still works bad, please report video bitrate and codec (it is shown by mplayer in console). Using correct video output driver is important, for n800 it should be [xv] (information about video output driver also should reported in console).

Also please run these two benchmarks from xterm or ssh, they should play the first 100 seconds of video and show statistics about the cpu time spent for video decoding, time for video output with scaling and time for audio. Also the number of dropped frames and average fps is also reported. The first cmd benchmarks normal playback, the second cmd benchmarks playback without audio.

> mplayer -benchmark -endpos 100 video.avi

> mplayer -benchmark -nosound -endpos 100 video.avi

The results would be very interesting to see, thanks in advance.

Maybe video acceleration will be used in one of the future software updates from Nokia. Also MPlayer is not optimized for N800 at all, so don't judge hardware capabilities by early versions of software, probably everything can be improved after software issues get resolved.

Very interested on this one also. N800 CPU has about 50% more MHz compared to 770 so it should do 640x225 30fps if 100% scalability would be true.

But I believe CPU has acceleration for display as well as some 3D acceleration (like N93 that has same CPU) also FPU is available. Maybe this could give even better performance if display rendering has been bottleneck in 770 mplayer(?)

Don't know if RAM speed is same as in 770 or interface towards SD cards, that could also be a bottleneck as well if SD card reading takes too much cycles.

Sadly cannot get N800 to test before going to closer to civilization from here :)

Thanks for the mplayer effort!

Thanks! I plan to test it and report the results to the mplayer thread.

Re: Divx movies on n800
 
So, are there any Divx files that are natively supported by the N800 video player? I tried a few and they didn't work: HT option on Divx converter, HT option on Dr. Divx 1.06, and Portable option on Dr. Divx 1.06. It read the length of the two Dr. Divx files but would not open them.

DivX and XviD are not supported as standard on the N800, however they should play ok with mplayer.

Supported video formats as standard: 3GP, AVI, H.263, MPEG-1, MPEG-4, RV (Real Video)

Use Media Converter to convert video first if you intend to use internal player. Here's a link:

If you need to use DivX movies, you need to install mplayer. That should be able to show divx movies out of the box, although performance for higher rez movies is still in tuning phase as serge doesn't yet have a N800.

Re: Divx movies on n800
 
I ran the media converter on a few divx files that I had, in order to make the prerequisit files for the n800 (I used the "mplayer best solution", or something like that, setting) and when I played the files they looked great, but moved in fits and start, both in the stock media player, and in mplayer. The files themselves never quite stopped playing, but it was like somone was hitting fast forward at random intervals. It did not matter if the file was playing at full screen or in a window -- and my load monitor showed that the processor was not redlining. the file was 400x160 (was widescreen -- with black bars on the top and bottom). I saved the "info" file but not sure who to get that too.
