One quick take:
import os
import re
import shlex
import subprocess
def sendToFFMPEG():
outPath = nukescripts.replaceHashes(nuke.thisNode()['file'].value())
base, ext = os.path.splitext(os.path.basename(outPath))
enc = 'ffmpeg -y -r 24 -i %s -an -vcodec libx264 -preset slow -profile
baseline -threads 0 ~/Desktop/%s.mov' % (outPath,
re.sub('[^A-Za-z0-9]?%0\d+d$', '', base))
subprocess.Popen(shlex.split(enc), stdout=subprocess.PIPE,
stderr=subprocess.PIPE)
Note that this doesn’t account for stereo output, but could be modified to do
so without much trouble.

Subject: [Nuke-python] How to Execute Shell FFmpeg Command in
AfterRenderCallback
Using a Write node's AfterRender callback, I want automate FFmpeg on Linux to
make a movie from an image sequence rendered out of Nuke.
Typically, this is handled by a dedicated render manager, which we don't have
in this case.
I think the callback function would look something like this but I'm not
certain about the subprocess.Popen stuff:
Code:
def ffmpeg(imageSequence, outputFilename):
cmd = 'mkdir %s' % (imagePath)
cmd = 'ffmpeg -y -r 24 -i %s -an -vcodec libx264 -preset slow -profile
baseline -threads 0 ~/Desktop/%s.mov' % (imageSequence, outputFilename)
print(cmd)
retVal = subprocess.Popen(shlex.split(cmd), shell=True,
stdout=subprocess.PIPE)
if retVal==['']:
return(0)
else:
return(retVal)
What python code can I use in the function call to pass the output filename and
output image sequence?
Any suggestions on the code above would be great!
