Should `video_metadatas` be `video_metadata` in `agent_loop.py` for Qwen3 VL?

[Solus-sano]

Description

Hi, I noticed that in verl/experimental/agent_loop/agent_loop.py, the processor is called with video_metadatas (plural form) as the parameter name on lines 290 and 661.

However, looking at the official Qwen3-VL repository, it seems the parameter name used is video_metadata (singular form):

processor(text=text, images=images, videos=videos, video_metadata=video_metadatas, return_tensors="pt", do_resize=False, **video_kwargs)

I'm wondering if this might be a typo, or is there a specific reason for using the plural form here?

Affected Code

Line 290:

model_inputs = self.processor(
    text=[raw_prompt],
    images=images,
    videos=videos,
    video_metadatas=video_metadatas,
    ...
)

Line 661:

multi_modal_inputs = self.processor(
    text=[current_text],
    images=images,
    videos=videos,
    video_metadatas=video_metadatas,
    ...
)
