Help with youtube script

snowman81 · 03-04-2008, 08:00 PM

I created a script that converts a youtube flash video to an mp3 then adds fake stereo sound and moves it into my mp3 folder. It creates the mp3 from the .flv ok but I think it is getting hung up after that.

Code:

#!/bin/bash

echo "Please type in name of file"
read NAME

sudo cp /tmp/Flash* /home/$USER/mp3/$NAME.flv

cd /home/$USER/mp3

sudo chown $USER:$GROUP $NAME.flv

ffmpeg -i $NAME.flv $NAME.mp3


sudo ecasound -i $NAME.mp3 -etf:8 -o /home/$USER/$NAME.mp3

cd /home/$USER

sudo chown $USER:$GROUP $NAME.mp3

sudo mv /home/$USER/$NAME.mp3 /media/Space/JasonC/My_Shared_Folder21

cd /home/$USER/mp3

rm *.*

I am also having a permissions problem with my external hard drive (media/Space) so that could be a part of it.

Looks wierd, you should only need sudo for doing 'root' type things (occasionally).
What you are trying to do should not need that.
Please post your /etc/fstab and /etc/mtab files.

It won't work without the sudo's. Maybe I'll go back and change permissions for the command or something.

Code:

Well, it sounds like you downloaded that file as root, not a good idea.
If you downloaded it as yourself, it should work.
If not, maybe it is the disk/mount perms, but it's a while since I knew that stuff. Maybe someone else can help or you can google it (fstab permissions vfat).
You could have a prob that vfat doesn't understand Unix perms, prob need to mount it rw for the world or as your own uid/gid.

Never mind, I found the problem. The line where it saves it to my shared folder. I accidentally renamed that folder and it had an erroneous space in the name. I could kick myself.

Bobzilla2639716495 · 03-07-2008, 01:28 AM

you think that you could set this up to create wav or mp4?

nullmind · 03-07-2008, 10:42 AM

This script could easily convert to mp4 because it usees FFMPEG. See the ffmpeg man (http://swoolley.org/man.cgi/1/ffmpeg) it might just require setting the output filename to *.mp4 (ffmpeg is rather slick like that) or require setting the output muxer to mp4 and audio codec to mp4a.

What is more irritating/difficult is getting it to recognize the input bitrate and leave it unchanged or detect it properly without using vbr/abr. FFMPEG isn't reliable to scrape output from (wasn't created for this) and libavcodec is rather undocumented and hard to use.

Cheers,
Kris

From some examples I've seen, it should be relatively easy to convert to mp4. I'm having a problem with my ffmpeg though. for some reason when I compile with mp4 support it still doesn't recognoxe it. I get this error:

Code:

 Seems stream 0 codec frame rate differs from container frame rate: 1000.00 (1000/1) -> 29.92 (359/12)
Input #0, flv, from 'flash.flv':

Stream mapping:

  Stream #0.1 -> #0.1
Unsupported codec for output stream #0.1

I don't know how to fix that.

nullmind · 03-07-2008, 11:58 PM

I've had this error at as well, although I'm using the ffmpeg in the ubuntu repos. You may wish to try -acodec to force the codec and you can also force the fourcc code (which I heard may be the cause of that error). Mencoder does a good job too.

Cheers,
Kris

snowman81 · 03-09-2008, 10:43 PM

I'll try the force codec option. Do you know the command you would use for the mencoder option?
