i am sharing a solution for pd to remix youtube video (download, transcode, sequence, fx). it's only for linux and it's using py.pd_linux (included for python 2.6) + python-gdata, mtl and other applications (readme.txt).

cool!!

hello,

yeah everything is working but the transcoding. ffmpeg transcodes from the terminal fine. ffmpeg, normalize and sox all installed from macports. python-gdata installed, etc.

downloads and cleans *.flv fine too... just no transcoding. and no errors in pd console.

hi,

for OSX maybe using the compiled py external from: http://grrrr.org/ext/beta/macos/pd/

but that's only to search / download video from youtube...

you will have to change how pd is started (portaudio in mac?) & youscrap.py (ffmpeg, path). i am sure it's doable.

yeah something like this works fine running the the terminal:

import os os.system('ffmpeg -i /Users/megrimm/Desktop/youtube2pd/footage/MuU00Q3RhDg.flv -an -pix_fmt yuv420p -vcodec mjpeg -s 640x480 -sameq -f mov -y /Users/megrimm/Desktop/youtube2pd/footage/test.mov')

os.system('ffmpeg -i /Users/megrimm/Desktop/youtube2pd/footage/MuU00Q3RhDg.flv /Users/megrimm/Desktop/youtube2pd/footage/temp.wav') os.system('sox /Users/megrimm/Desktop/youtube2pd/footage/temp.wav -r 44100 /Users/megrimm/Desktop/youtube2pd/footage/test.wav') os.system('normalize-audio /Users/megrimm/Desktop/youtube2pd/footage/test.wav')

so I am assuming its a path problem with your script? since it downloads and cleans. although why would it be able to clean the downloaded file from '+savepath+'/footage/' but not able to find to transcode?

hi mark,

you can try with a simple python script something like:

import os os.system('ffmpeg -i /Users/bla/video.flv -vcodec mjpeg /Users/bla/video.avi')

if it's working, then maybe it's a problem with the savepath. also starting pd in a terminal might give you more info.

yeah works fine run from terminal, just not when opening patch directly from osx finder. only error is this: sys:1: RuntimeWarning: Python C API version mismatch for module pyext: This Python has API version 1013, module pyext has version 1012.

should this really matter? maybe it does... i dont know.

see output below.
