Never heard of them. What DSP do they use, and through which driver API?

VLC bears no direct relation to ffdshow, so I cannot comment on that.

Of course, supporting DSP improves performance a lot. Even Cortex-A8, which is 
by far the most powerful ARM core in the market to this day, won't decode high 
definition video in real time.

To "upstream" DSP support into VLC, we'd need someone to submit the code to 
vlc-devel. Also, it probably needs the kernel driver to be upstreamed into the 
operating system too. And then, the hardware should be open, otherwise you 
will never be able to run your own VLC on it anyway.
