Nathan,
This is fantastic, thanks!
I've made a few changes:
--
import os, re, shlex, subprocess
def sendToFFmpeg():
# grabs the write node's file value and makes sure the path uses printf style
filenames
imgSeqPath = nukescripts.replaceHashes(nuke.thisNode()['file'].value())
# generate mov path
base, ext = os.path.splitext(os.path.basename(imgSeqPath))
movPath = os.path.dirname(os.path.dirname(imgSeqPath)) + '/' +
re.sub('\.?%0\d+d$', '', base) + '.mov'
# make shell command
enc = 'ffmpeg -y -r 24 -i \'%s\' -an -vcodec libx264 -vpre slow -crf 22
-threads 0 \'%s\'' % (imgSeqPath, movPath)
subprocess.Popen(shlex.split(enc), stdout=subprocess.PIPE,
stderr=subprocess.PIPE)
--
Specifically,
Updated the mov path to write the mov one directory up from the image
sequence
Added escaped quotations marks around the shell path
Updated the ffmpeg call for the default compile on ubuntu 11.10
It works well, though I have a couple questions:
Why did you use
[^A-Za-z0-9]? instead of just \. in the re.sub() call?
If the file value passed from the Write node has any TCL, ffmpeg
obviously fails. Is there a way around this?
Lastly, for anyone else attempting this, remember that ffmpeg assumes the image
sequence starts at frame 0. At some point, I'll have to work out a way to pass
any offset to the command.
