So it's hard to know how much of the improvement is due to compiling for v6 over v4t, soft-float vs vfp, armhf ABI vs armel ABI, and possibly variation in gcc used. I suspect all of those are mixed in.
Agreed, but wow, the MP3 encode differences of 5x+ are dramatic (is that using lameenc?).
That's probably largely due to softfp vs vfp. We'd expect that to make a pretty dramatic difference.
I assume the Ogg encoder is fixed-point and therefore doesn't get the hf benefit.
You need to link against libtremor to get integer ogg en/decoding and few apps do, so I'd expect it to be fp too. But without the details of what was tested we can't tell from here.
Wookey
