Re: [Gnash-dev] I tried Gnash0.8.2 on my arm board, but found it too slow

Hi Rob Savoye,

Thank you Rob!
I understand what you mean: animation decoding is different from video. 
So the video decoding acquire more CPU time.

I have a hardware platform support H.264 and MPEG4 hardware decoder. the 
device driver for which has been implemented under linux.
Does that means gnash can make use of the hardware decoder?

I'm thinking about using gnash as an GUI platform for some device, such 
as control panel of home appliance: it can play online video, local 
flash file and what's more, the flash can provider pretty friendly user 
interface...

Now I'm using SDL as UI IF. the touchscreen input has problem yet. I 
will also try to use it under GTK, which I did cross compile before.


Best Regards,
Xu haigang
