Description of the bug:

I got extra_forbidden error when trying to set custom fps for video processing using client.models.generate_content. (code reference: https://ai.google.dev/gemini-api/docs/video-understanding). Please share if you have ran into the same issue and look forward to hearing how you solved it!

My code:

with open(video_local.name, 'rb') as f:
                    video_bytes = f.read()
                
                # Create content using inline data
                response = await self.gemini_client.aio.models.generate_content(
                    model=model,
                    contents=types.Content(
                        parts=[
                            types.Part(
                                inline_data=types.Blob(
                                    data=video_bytes,
                                    mime_type=mime_type,
                                    video_metadata=types.VideoMetadata(fps=5)
                                )
                            ),
                            types.Part(text=prompt)
                        ]
                    )
                )

Actual vs expected behavior:
