Hi Rob Savoye, Seems like now the gnash need high speed and high memory from hardware.I will try " --enable-media=ffmpeg --enable-jemalloc CXXFLAGS=-O3" and play a swf with small resolution.
I have used the flash player on windows mobile, I think it's fast and acceptable. That's right, as told by Russ Nelson,the software need to be optimized for ARM processor.
Best Regards, Xu Haigang Rob Savoye ??:

My nokia n810 plays videos very nicely, so clearly the hardware can play video, it's just a question of having software which works well on the ARM processor.Your N810 uses hardware decoding, which is why the performance is acceptable. Doing 100% software decoding and rendering on a 400Mhz processor with only 64M of RAM is always going to be slow. I have found that if you play a video without having to rescale, a 400Mhz cpu can do 10-15 fps, but with 64M, there isn't much room for buffering.Btw, the Gnash reference manual talks about cross configuring and compiling Gnash for the ARM, it that helps. Me, I configure with --enable-media=ffmpeg --enable-jemalloc CXXFLAGS=-O3.- rob -
