How to output long (30min-2h) videos?
When using theVideocomponent to output a video that are around 40 mins long, I encounter timeouts. Could someone please suggest a workaround for outputing long videos?Replicating the issueIf you don’t have a >40 min mp4 h264 encoded video available locally, download the Blender Bunny video (https://ia803407.us.archive.org/0/items/big-bunny-sample-video/SampleVideo.mp4) and run the following command, it takes seconds and the output is 416MBs:ffmpeg -stream_loop 40 -i SampleVideo.mp4 -c copy LongSampleVideo.mp4import gradio as gr

def greet(name):
    return "Hello " + name + "!"

with gr.Blocks() as demo:
    name = gr.Textbox(label="Name")
    output = gr.Textbox(label="Output Box")
    greet_btn = gr.Button("Greet")
    greet_btn.click(fn=greet, inputs=name, outputs=output)
    # input components above are just dummies to ensure that output loads
    gr.Video("LongSampleVideo.mp4")
demo.queue() # a futile attempt to avoid timeouts
