Fatal Error R
....
First, I'm thankful about your wonderful project.
However, I have serious worries about the reliability of R. I found
the next bug which I consider important because in my job everytime We
work with datanames like next. Please see below:
b=data.frame(matrix(1:9,ncol=3))
names(b)=c("q99","r88","s77")
>b
q99 r88 s77
1 1 4 7
2 2 5 8
3 3 6 9
> b$q9
[1] 1 2 3
Please note that the variable q9 does not exist in the dataframe, but
you can see that R
show q9 (as q99).
Thank in advanced
Cordially

quality question
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
If I'm going from .wav --> .ogg -q9 --> .ogg -q7 do I suffer any ill effects
or is it just like going from .wav --> .ogg -q7 ??
I ask because I think I want to go down a bit more as the size of the files
are around 10mb or so. I can get them from source again and go straight to
- -q7 if need be.

Theora file size
Hi
I was surprised with size of Theora files and thought
of feedback.
Following 1minute duration Theora and Xvid files were
made from a y4m file. The resolution is 1280x720:
1. Xvid 17MB
2. Ogg/Theora Q7 31MB
3. Ogg/Theora Q8 38MB
4. Ogg/Theora Q9 49MB
5. Ogg/Theora Q10 61MB
The Xvid file was made using mencoder by 2 passes with
following options:
bitrate=2500:autoaspect:chroma_opt:vhq=4:bvhq=1:quant_type=mpeg:pass=1
The encoder_example was used to create Ogg/Theora
files.
It was noted y4m to Theora encoding was the fastest
that I hav...

[LLVMdev] NEON intrinsics preventing redundant load optimization?
....data[i];
return result;
}
void TestVec4Multiply(vec4& a, vec4& b, vec4& result)
{
result = a * b;
}
With -O3 the loop gets vectorized and the code generated looks optimal:
__Z16TestVec4MultiplyR4vec4S0_S0_:
@ BB#0:

vld1.32 {d18, d19}, [r0]
vmul.f32 q8, q9, q8
vst1.32 {d16, d17}, [r2]

However if I replace the operator* with a NEON intrinsic implementation (I know the vectorizer figured out optimal code in this case anyway, but that wasn't true for my real situation) then the temporary "result" seems to be kept in the generated...

peeling as I understand it (was Re: When will quality increase be unnoticable?)
...on after
RC4's release.
After 1.0 is out the door, then some attention will be paid to "hinting" to
make peeling easier, and peeling tools will finally be written.
It is suspected that RC3 or RC4 or 1.0 files may not peel perfectly. That
is, if a file is encoded at (for example) q9, and subsequently "peeled" to
q6, it may not sound quite as good as the same file originally encoded at q6.
So they'll peel, and the bitrate (and filesize) will be right where you want
it, but the quality may be sub-optimal. But this depends probably on how
"smart" the...

[LLVMdev] Vector argument passing abi for ARM ?
Hi Sebastien,
> Thanks for the quick answer, how do I know which type is legal/illegal with respect to calling convention ?
the code generators are supposed to produce working code no matter what the
parameter type is. The fact that the ARM ABI doesn't specify how <2 x i8>
is passed just means that the code generators can pass it using whatever
technique it feels like (since it

[PATCH 0/5] ARM NEON optimization for samplerate converter
From: Jyri Sarha <jsarha at ti.com>
I optimized Speex resampler for NEON capable ARM CPUs. The first patch
should speed up resampling on any platform that can spare the
increased memory usage. It would be nice to have these merged to the
master branch. Please let me know if there is anything I can do to
help the the merge. The patches have been rebased on top of master

ABX at q8
...ettings ......... I use q8, because:
- I was able to ABX some test samples up to q4.99
- at q8 Ogg is still around 3.5x smaller than lossless
- it sounds perfect to me!!
I was just courious to know if anyone out there is able to distinguish
from the original (ABX) Vorbis 1.0 at around q8 (or q7 to q9) on "NORMAL
MUSIC" (not special test samples)??
What about q5 to q7?
Thank you all.
