Howto: Youtube auto-upload script

March 3, 2010

So you’re making lots of movies and you want things to upload to youtube automatically without you having to do any heavy lifting? If you are comfortable with a little bit of terminal and command line stuff, no problem.

A few things you will need:
Gmail account and Youtube account. These will be linked. You can use one gmail account as the developer for multiple youtube accounts but each youtube account needs it’s own independent email address, and for multiple gmail accounts you might need to get some dummy address at yahoo.com or mail.com as an alternative email. Then get yourself a developer key while logged into your developer gmail account.

Python 2.6 is probably already installed. But if not, install that too.

We’ve gotten this working for MacOSX and Linux (ubuntu 9.10 and fedora 11 anyway).
It’s probably not too hard to get it working with Windows but we’ve never tried.

Files you need:
uploader2.py at http://gist.github.com/319734
edit login information for youtube and gmail accounts.
edit developer key. edit the keywords and description to fit your project.

videochecker.sh at https://gist.github.com/e2569bca9313b1056c0e
check the path.
Thanks to Sean Levin for writing these.

Gdata and Atom directories. They are zipped and downloadable here: http://www.divshare.com/download/11521457-3da Unzip and place into same directory as uploader2.py.

Copy these files into whatever directory you will be uploading videos from.
You will now need to edit both of these files as noted above. Do you have a favorite text editor for simple code? We like smultron on mac and gedit or emacs on linux but any will do. Whatever music you like.

make sure both files are executable.

chmod 755 uploader2.py
chmod 755 videochecker.sh

then try it out manually. from the video directory prompt try running the videochecker.
yourvideodirectory$ ./videochecker.sh

yourvideodirectory$

if you’re getting an error with videochecker, try changing the first line to
#! /bin/bash -ex and it will output lots of extra info as it runs.

Ok. So you made it that far and now you want to set it up so it runs automatically each day or week or hour. Time for crontab. What is a crontab you ask? It’s sort of like asking your alarm clock to run a program instead of make a loud sound. It’s just a simple text file that you add some instructions to. The only problem is that you usually edit it in vi (a text editor). vi is nice and all but it’s rather confusing if you haven’t used it before. With vi, there are 2 modes, insert-text mode and command mode. 3 most useful key sequences are:
i – enter insert mode,
esc – exit insert mode
ZZ – save file and exit program.
Want to learn more: http://heather.cs.ucdavis.edu/~matloff/UnixAndC/Editors/ViIntro.html

In the terminal window (here your current path matters not), enter
crontab -e
type i to put the editor in INSERT mode. (see text in bottom left of editor)

– then make your crontab look like:
# m h dom mon dow command
*/10 * * * * /home/yourlinuxboxname/Videos/Webcam/videochecker.sh

(which runs that script every 10 minutes.)
or

# m h dom mon dow command
* 3 * * * /home/yourmac/Movies/AUTOUPLOAD/videochecker.sh

(which runs that script at 3am each evening. But only when the computer is awake.)

– hit the ‘esc’ key to get out of insert mode.

– then type ZZ to save and exit.

Let us know how this works for you and we will try to keep an updated version of these instructions.

python uploading scripts for youtube

July 27, 2009

UPDATE:
consider skipping this post and going right to this newer one: https://broadcasterproject.wordpress.com/2010/03/03/howto-youtube-auto-upload-script/

http://code.google.com/apis/youtube/1.0/developers_guide_python.html

many thanks to sean levin for writing the upload scripts.

basic script functionality:

check a folder periodically
if movie file is there: upload it, then move it somewhere else.

that covers the basics. here are some more details.

make softlink for no space version of “Photo\ Booth”
ln -s /Users/yourname/Pictures/photobooth /Users/yourname/Pictures/Photo Booth/
crontab to call shell script periodically.
shell script functionality: check for directory and lock file. make lock file. look for files. call python uploader with file. cp file with new timestamped name. mv file.

now the problems.

1. login problems. i think this has to do with the way that youtube and gmail are now linked in some account. including the edlabbroadcaster account. i made edlabbroadcaster2 that is not linked to google account and that seems to fix log in problems.

2. conversion problems. lots of the videos fail to convert. and some convert to junk like this.

and a static shot of the conversion errors.
youtube conversion errors

tried with some avi files and it works so i’m guessing it’s the .mov format. does built in camera on an imac generate different .mov files than external isight firewire camera on a macmini? that is the question i am pondering.

is there another 3rd party photobooth style software that will write a different format video?

login problems persist as well. would love to move to something other than youtube. it seems youtube gets very confused about login now as accounts are linked to google accounts. so you can’t change password anymore or anything. its really annoying.

UPDATE on login:
so i was working on this today (2009-aug-4) and had several succesful uploads. then 2-3 in a row had login problems with no change to code. then waited 5 minutes and login is fine.

still working on this issue of videos that go grey: http://www.youtube.com/watch?v=UacDMt3hhZY

some question asking on developers forum.
http://groups.google.com/group/youtube-api-gdata/browse_thread/thread/e5f7f73e111162a9#

update:
login issues seem to be mostly fixed now.
conversion errors may have something to do with the filme movement while photbooth is still open. it seems the first of “movei 1.mov” always seems to upload fine. but the next one often has a conversion error. maybe photobooth has some issues with file movement going on while it’s still open? should the files be left in the directory and only moved once a day or something? should photobooth be closed and restarted? is there a photobooth alternative that might work better? use screencapture program like ishowuhd combined with processing or openFrameworks webcam monitor?

installing ffmeg on mac os x

July 27, 2009

i’m on a mac mini. 1.83 intel core duo. 1 gb ram.

os x 10.5.4.

my notes on ffmeg install following this article  — http://stephenjungels.com/jungels.net/articles/ffmpeg-howto.html

 tar xvzf lame-3.97.tar.gz

(this line didn’t work for me because mc os x automatically unzipped for me) so instead i need to get rid of the z.

tar xvf lame-3.98-2.tar

then a couple lines down there is a 

./configure

this didn’t work for me either. i got

… configure: error: no acceptable C compiler found in $PATH See `config.log’ for more details.

now i’m downloading xcode and developer tools. i’m assuming this will cover the c compiler part. http://developer.apple.com/technology/Xcode.html

ok. this block works now. 

./config

make

sudo make install 

optional: 

same issue with tar after downloading. i could get the command line download line to work. so i went to download faad from sourceforge. and then used this tar line

tar xvf faad2-2.7.tar

then i ran ./configure, make,and make install.

now back to ffmpeg. mkdir. cd. svn.

“Checked out revision 19521.”

long configure line. make (this is a long one). sudo make install.

now i noticed the additional config flags for the aac stuff. so i go back and run config again.

 

 

 ./configure –enable-libmp3lame –enable-shared  –disable-mmx –enable-libfaac –enable-libfaad

libfaad2 is gpl and –enable-gpl is not specified.

If you think configure made a mistake, make sure you are using the latest version from SVN.  If the latest version fails, report the problem to the ffmpeg-user@mplayerhq.hu mailing list or IRC #ffmpeg on irc.freenode.net. Include the log file “config.err” produced by configure as this will help solving the problem.

not sure what this means but i’m moving on…
so here i am. first try.
$ ffmpeg -i codemovie.mov codemovie.flv

codemovie.mov: Unknown format

tar xvf faad2-2.7.tar

it can’t understand the native .mov files written by photobooth. that’s all for now. back to this at a later date.
