Does it make a difference if you insert the scale filter?
-vf scale=640x360,zoompan=z='min(zoom+0.0015,1.5)':d=125:s=640x360

What about an AMD Octacore cpu optioned with highest amount of caches and
highest clock speed available, and of course full complement of RAM that
the mobo can handle?
If you still want intel, then choose
Intel Core i7-4790K @ 4.00GHz

Hi users,
I am wondering about the ffserver stats on stat.html page. There are two
fields; Bit rate and Video kbits/s and I can see my video stream bit rate
specified from ffmpeg in the field Video, but I see a low value of 128
kbits/s in the Bit rate field.
The two fields are contradictory and

The following are the default (and have no effect),
you can remove them:

If I add scale filter after crop filter i.e. -vf crop=650:480:103:0,

It's not correct. Not 4:3 video. Just same as black band removed video...

If you change LABELED_BRAND_NAME in line

Thanks for the info! Yeah, I was considering the AMD 8-core chip over the
i7-4790k, but everything I was reading was suggesting the i7 over the

of FFMpeg task, i.e. SSD over SATA?
