[maemo-developers] Video decode capability of N810

[From: Martin Grimme]

Hi,

the N810 cannot handle videos in VGA resolution very well. At least on the
N800 the video bandwidth is rather limited (in contrast to the Nokia 770)
and I assume that the video hardware on the N810 is the same.

Video decoding, however, works fine with lower resolutions such as QGA.
ffmpeg runs fine on the N810, but is not installed there by default. The API
for DSP accelerated video decoding on the N810 is gstreamer (
http://gstreamer.freedesktop.org), which is opensource software. Some
gstreamer plugins on the N810 are closed source, though.

Without using gstreamer, you can get very good video playback with mplayer (
http://mplayer.garage.maemo.org). By using mplayer's slave mode, you can
embed the player into your own applications, like  kmplayer, Kagu, and
MediaBox do.


Cheers,
Martin
