Re: How To Do Noise Reduction Using ffmpeg And sox

You should not use `-sameq` option, the name doesn't mean what you think it does.
You do not need to re-encode the video stream.
The command for merging two stream should be:
ffmpeg -i Ktmpvid.mp4 -i tmpaud-clean.wav -map 0:v -map 1:a -c:v copy -c:a aac -b:a 128k out.mp4

Thank you for the tutorial! I follow, but the page still say "SSL connection error" and i don have idea way, the server say "_default_ VirtualHost overlap on port 433, the first has precedence
".

That may be the case however hohoho is correct. If you have other certs there because you previously had created them for other applications and are just following this to enable ssl on apache then of course the other certs don't need to be copied over so a full directory copy is not the correct way. If thats not the case and the tut follower has only installed ssl to configure apache then your tutorial commands will be perfectly fine.

I downloaded FFMPEG and it is a BZ2 file, how do I install the program? Thanks

jim.ji is correct you can't be a straight-up print.
While we're at it though, you can eliminate a lot of the math and if statements except for a bit right at the start, and allow for any N:

We know that the pattern repeats for every 15 n. So why not just determine the length, then print the repeating string until you get to the necessary length?

hah but its not saving/reading anything from the hdd what was the main point of "1 command" anyways :)

you cheated ;) using pipe is still two separate commands, only called on the same line...

Re: How To Do Noise Reduction Using ffmpeg And sox

gondoSVK — Thu, 14 Nov 2013 07:45:01 -0000

actually there is:
sox input.wav -n noiseprof | sox input.wav output.wav noisered - 0.2

im having consistent noise so i can just take first 0,5s of the sound to profile it

Re: How To Do Noise Reduction Using ffmpeg And sox

Zohar Babin — Thu, 14 Nov 2013 07:11:10 -0000

Wish there was, however I don't think so... I'd also like to find an automatic way to find the time in the video where the noise happens on its own, so that we could generate the profile automatically.

Re: How To Do Noise Reduction Using ffmpeg And sox

gondoSVK — Thu, 14 Nov 2013 03:40:30 -0000

is it possible to generate the profile and clean the noise in 1 command?

@hohoho -
These two methods are the same... the first tells cp to copy the file with its original file name to the dest directory, while the second (your suggestion) tells cp to copy over using a specific file name (which happens to be the same in this case).

step 5

cp server.key /etc/apache2/ssl
cp server.crt /etc/apache2/ssl
should be
cp server.key /etc/apache2/ssl/server.key
cp server.crt /etc/apache2/ssl/server.crt

Hi there,

I'm also trying to join together two bytearrays generated by FLVencoder and am having the same error:
RangeError: Error #2006: The supplied index is out of bounds. at flash.utils::ByteArray/writeBytes()

Did you find a solution?

Thanks,

Lezlea

Hi Zohar,

Thanks for these instructions. I just wanted to report that ffmpeg now (February 2013) requires yasm 1.2.0 and the apt repository still has 1.1.0, so I had to build yasm separately to then get ffmpeg to build.

jim ji — Thu, 21 Feb 2013 06:10:01 -0000

if N is a const number, print the result directly is the most efficient way:)

like this:

// N is 100.
print("1\n2\nFizz\n4\nBuzz\nFizz\n7\n8\nFizz\nBuzz\n11\nFizz\n13\n14\nFizzBuzz\n16\n17\nFizz\n19\nBuzz\nFizz\n22\n23\nFizz\nBuzz\n26\nFizz\n28\n29\nFizzBuzz\n31\n32\nFizz\n34\nBuzz\nFizz\n37\n38\nFizz\nBuzz\n41\nFizz\n43\n44\nFizzBuzz\n46\n47\nFizz\n49\nBuzz\nFizz\n52\n53\nFizz\nBuzz\n56\nFizz\n58\n59\nFizzBuzz\n61\n62\nFizz\n64\nBuzz\nFizz\n67\n68\nFizz\nBuzz\n71\nFizz\n73\n74\nFizzBuzz\n76\n77\nFizz\n79\nBuzz\nFizz\n82\n83\nFizz\nBuzz\n86\nFizz\n88\n89\nFizzBuzz\n91\n92\nFizz\n94\nBuzz\nFizz\n97\n98\nFizz\nBuzz\n");

Thank you for the tutorial! I am on Ubuntu 12 but still had to create the symlink for default-ssl (step 7). Strangely, the symlink for default was already there.
