When using the Video component 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 issue
If 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.mp4
import 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
demo.launch()
