Looks like my ASM change is not happening or cygwin/windows2000 cannot handle
it since all my tests are dying on it after 54-194 frames. I tried:
lav2yuv test.avi | mpeg2enc -f8 -o t.avi #which locked up every time
#then:
lav2yuv test.avi > test.yuv
mpeg2enc -f8 -o t.avi < test.yuv
both lock up
By the way: I am attempting to compile everything on cygwin. I have had to
download and try to install the following:
SDL-1.2.5: success (I was suprised at this)
avifile0.7-0.7-22: failed
glib-2.0.7: requires libiconv and pkgconfig but link failed miserably after
succesfully obtaining dependent pa
I changed line 394:
punpcklwd mm5, [INP+8]
to these two lines:
movd mm2, [INP+8]
punpcklwd mm5, mm2
since nasm had a problem with the source size.
I hope this works. It's been a while since I have done ASM, z80, x86, 6510
and never have seen the MMX instruction set before to

Yeah, I seemed to have gotten it up to about 4fps or thereabouts,
Hi Brian,
I checked the numbers for 720x480 input which is DVD resolution.

You have the interlaced (-I 1) flag
I'm trying to use yuv2divx on a debian unstable system, but it is
segfaulting right when it starts. Is this a known problem? I've tried
it on a few different systems and all have the same problem.

The advice I was given several days ago on improving hqdivx to svcd
conversion speed has really helped me out. With my new pipeline I can
get between 6.5-7.5 fps from NTSC sources and 4.5-5.5 fps from PAL
sources (actually, I'm sure the encoding rate is better than that; the
fps computation includ

Hi "b.",
First off we need to make sure we're comparing like with like.
For a test.avi which is 720x568 full-size PAL video:
lav2yuv test.avi | mpeg2enc -f 8 -o /dev/null
my old PIII-500 (Katmai core) delivers just under 1.5 frames/sec.
my Duron-800 delivers roughly 3 frames/sec.
my Athlon/X

Hi Brian,
Is there another process in your pipeline that could be causing the
slowdown?
In my personal experience, the raw MPEG encoding speed of an Athlon
700Mhz is around 30fps for VCD resolution with default encoder settings.
There are some benchmarks at http://klicman.org/altivec/ if your

800MHz Athlon ThunderBird. The mpeg2enc was build on this machine so
(hopefully) it is tuned for the Athlon's processor features. I did
see mention of MMX being used during the startup of mpeg2en

I am trying to convert some MJPEG that I captured with my G400 Marvel
to MPEG2. I have tried an mpeg2enc coomandline sever al times but
it's too slow. The best I can get (with bad quality switches) is
2fps. But at that rate every hour I record will take 15 hours to
convert.
