That's cool :)
Question:
1) Is it correct for me to use the dspfbsink directly? (Frame
buffer) Any pre-processing necessary?
I'd guess it isn't, but don't know. You would be missing the new window
so it looks like there should be other way.
2) The w.mpg plays correctly on the bundled 770 movie player, but
pretty slowly with a lot of frame skips. Is the CPU of Nokia 770 fast
enough to handle more advanced codecs, like xvid?
All the decoding is done by the DSP. This is IMO bad design choice for
(advanced) video. DSP is simply overused and too slow for this. When
playing the ice age trailer you can notice with load applet that CPU
sits almost idle while DSP is struggling to decode everything. This
makes sense for backgroung sound playback, but not for video. You hardly
play video on the background :-)
It would be interesting to hook in mp4 gstreamer plugin that decodes
video by the main CPU. This could result in much higher framerates or
better resolution and better utilization of both main CPU and DSP. Or is
there some catch why doing it on DSP makes better sense? AFAIK the main
ARM CPU should be better suited for the task than the DSP.
BTW How much dedicated video memory is there? Can the video driver do
double buffering directly in video memory? This would be useful for
video playback too.
