From python you can run it through hou.hscript()

Before all, OpenGL ROP. You may find it more convenient to work with this node using Python.

 

hou.GeometryViewport.saveFlipbook() still not in H15, but you can invoke HScript command viewwrite from Python. Example:

import hou
import toolutils


def viewname(viewer):
    viewname = {
        'desktop' : viewer.pane().desktop().name(),
        'pane' : viewer.name(),
        'type' :'world',
        'viewport': viewer.curViewport().name()
    }
    return '{desktop}.{pane}.{type}.{viewport}'.format(**viewname)


def viewwrite(options='', outpath='ip'):
    current_view = viewname(toolutils.sceneViewer())
    hou.hscript('viewwrite {} {} {}'.format(options, current_view, outpath))


viewwrite('-q 4 -f 1 10', "$HIP/flipbook/'$F3'.jpg")

Hi,

Colud You tell why it's not working reading the files back.

hou.hscript( "loadseq -r a:/Projects/HoudiniTests/Python/flipbook/'$F3'.jpg")

print 1

Looks like it's MPlay-specific. Houdini doesn't know about loadseq command. Forum search says that you are first living human trying to use this command. hou.Mplay functionality still not implemented at all, like flipbook generaition classes, so, you are out of luck even with HScript, probably.

From Houdini Textport:

/ -> help loadseq
No installed command matches loadseq

From MPlay Textport:

mplay -> help loadseq
loadseq

    Loads a sequence of files into mplay.

 

But it is extremely easy to directly call MPlay as a program using Python:

import subprocess
import hou

ip = hou.expandString('$HB/mplay')
seq = hou.expandString('$HIP/flipbook/*.jpg')
subprocess.Popen([ip, seq])

Thanks,

It is easy, but you know any easy method to bring mplay app to front?

Thanks in advance!
