MEDIASESSION

Awesome! Thanks for your help. I got pretty far in coding the Quicktime settings. But there are a few settings that I am having trouble with. (Datarate, Audio Samplerate and Audio Bitrate)

import c4d
from c4d import bitmaps
import maxon

def main():
    
    QUICKTIME_FORMAT_NUMBER = 1073784596

    # Retrieves render data and its container
    renderData = doc.GetActiveRenderData()
    bc = renderData.GetDataInstance()

    # Gets image filters options
    saveOptions = bc.GetContainerInstance(c4d.RDATA_SAVEOPTIONS)

    # Sets Quicktime Mov output format
    bc[c4d.RDATA_FORMAT] = QUICKTIME_FORMAT_NUMBER # c4d.FILTER_MOVIE sets format to mp4 not mov, so I used the call command instead

    # Defines Quicktime settings
    compressionmethodID = maxon.InternedId('net.maxon.mediasession.mf.export.codec')
    datarateID = maxon.InternedId('net.maxon.mediasession.export.datarate')  # Problems here needs BytesValue
    keyframesID = maxon.InternedId('net.maxon.mediasession.export.keyframes')  # Asks for Int32 and works
    audiocodecID = maxon.InternedId('net.maxon.mediasession.mf.export.audio.codec')
    audiosamplerateID = maxon.InternedId('net.maxon.mediasession.mf.export.audio.samplerate')  # Problems here asks for Int but doesn't like it'
    audiobitrateID = maxon.InternedId('net.maxon.mediasession.mf.export.audio.kilobitrate')  # Problems here asks for Int but doesn't like it'
    

    # Configures Quicktime format options with a maxon.DataDictionary
    exportSettings = maxon.DataDictionary()
    exportSettings.Set(compressionmethodID, maxon.Id("H.264"))  # works
    
    exportSettings.Set(datarateID, 2)  # does not work
    exportSettings.Set(keyframesID, 2)  # works
     
    exportSettings.Set(audiocodecID, maxon.Id("mp3")) # works
    
    exportSettings.Set(audiosamplerateID, 96) # does not work (adds new fake setting)
    
    exportSettings.Set(audiobitrateID, 320) # does not work (adds new fake setting, notice no kBit)
    
    # Stores settings in render data container
    bitmaps.SetImageSettingsDictionary(exportSettings, saveOptions, QUICKTIME_FORMAT_NUMBER)

    # Updates Cinema 4D
    c4d.EventAdd()

if __name__=='__main__':
    main()

Datarate, Audio Samplerate and Audio Bitrate are not being set.

Keyframes, which asks for an Int32, does get set successfully.

Datarate asks for BytesValue. I can't figure this out. What is a BytesValue, what does it look like in python, and do I need to import it?

Audio Samplerate and Audio Bitrate ask for an int. I include an int, but it doesn't work. It actually adds a new fake value to the bottom of the pull down which is not correct. How is this different than an Int32?

Thanks for your help.

GetImageSettingsDictionary()

Ok. R20 is fine. Could I see a code example for SetImageSettingsDictionary() in python?

I've tried to follow the C++ code example:
https://developers.maxon.net/docs/Cinema4DCPPSDK/html/page_manual_renderdata.html
But I can't seem to create a DataDictionary in python. And there is no information on them in python.

And I don't know what the settings are called.
The standard "drag attribute to console" gets me:
foo[1852142638,1835104367,1848536421,1684627827,1702065001,1869491823,1885695589,2020748901,2020634482,1949198433,1818650220,1868657664,c4d.MEDIASESSION_PROPS_NET_MAXON_MEDIASESSION_OPENEXR_EXPORT_HALFFLOAT]

Ultimately I'm mainly interested in setting the Quicktime or Avi settings. But would be happy to get the EXR working as a start.

Thank you.

How do you set Quicktime options. (like ProRes, h264, data rate, etc.)

I've tried using this older code with EXRs. But it doesn't seem to work for EXRs anymore.

import c4d
rd = doc.GetActiveRenderData()
container = rd.GetData()

# OpenEXR
container[c4d.RDATA_FORMAT] = c4d.FILTER_EXR

saveOptions = container.GetContainerInstance(c4d.RDATA_SAVEOPTIONS)

# OpenEXR options
bc = c4d.BaseContainer()
bc[0] = 3 # ZIP
bc[1] = True # clamp to half float

# save OpenEXR options
saveOptions.SetContainer(0,bc)

# save render data
rd.SetData(container)

c4d.EventAdd()

The above doesn't set the zip or half float.

I've also looked into using the MovieSaver class.

But still couldn't get where I needed to go. The code in that post also didn't seem to work.

How do I set the Quicktime options with Python?

This worked. Thank you.

Here's a simple test to run in the script editor:
Add a Cube to the scene.

import c4d
current_doc = c4d.documents.GetActiveDocument()  
cube = current_doc.SearchObject('Cube')

def AddStringDataType(obj):
  if obj is None: return

  bc = c4d.GetCustomDataTypeDefault(c4d.DTYPE_STRING) 
  bc[c4d.DESC_NAME] = "String"           

  element = obj.AddUserData(bc)  
  obj[element] = 'bob'       
  c4d.EventAdd()             
  
def AddFloatDataType(obj):
  if obj is None: return
  bc = c4d.GetCustomDataTypeDefault(c4d.DTYPE_REAL)
  bc[c4d.DESC_NAME] = "Float"
  element = obj.AddUserData(bc)
  obj[element] = 22.2
  c4d.EventAdd()
  
AddStringDataType(cube)
cube.RemoveUserData(1)
AddFloatDataType(cube)

If I add a string field with AddUserData.
And then I delete that string field with DeleteUserData.
And then try to add a float field with AddUser Data:
I get
TypeError: setitem expected str, not float
And if I try to get the value before EventAdd, I get the old, deleted value

Anyone know any workarounds? Like how to flush the memory of the user data?
