Video component can't download URL behind a proxy #10726

Something isn't working

What proxy are you using? Can you explain how you set it up so we can try to reproduce this? |
|
This is behind a "corporate" web proxy, e.g. https://www.squid-cache.org/. |
|
Hmm this might be tricky to reproduce, but are you certain https://github.com/intel-iot-devkit/sample-videos/raw/master/person-bicycle-car-detection.mp4 is accessible through your proxy? What happens when you run this: import requests
url = "https://github.com/intel-iot-devkit/sample-videos/raw/master/person-bicycle-car-detection.mp4"
response = requests.get(url, stream=True)
if response.status_code == 200:
print("File is accessible. Saving...")
with open("person-bicycle-car-detection.mp4", "wb") as f:
for chunk in response.iter_content(chunk_size=8192):
f.write(chunk)
print("Download complete.")
else:
print(f"Failed to access file. HTTP Status Code: {response.status_code}") |

I kind of confirmed this issue, by installing the Squid Web Proxy, and running a test app with http_proxy and https_proxy env vars. Install Squid: https://documentation.ubuntu.com/server/how-to/web-services/install-a-squid-server/index.html Do a test request: export https_proxy=http://localhost:3128
export http_proxy=http://localhost:3128
curl www.google.comCheck the access log: sudo cat /var/log/squid/access.log The log shows: 1741122617.179 109 ::1 TCP_MISS/200 17789 GET http://www.google.com/ - HIER_DIRECT/142.250.217.100 text/htmlNow, write a test application: import gradio as gr
def create_interface():
with gr.Blocks() as demo:
gr.Video(
label="Input Video",
interactive=True,
value="https://github.com/intel-iot-devkit/sample-videos/raw/master/person-bicycle-car-detection.mp4",
sources="upload",
)
return demo
demo = create_interface()
demo.launch(
server_name="0.0.0.0",
server_port=7860,
)Run it: python test.pyCheck the access logs again: sudo cat /var/log/squid/access.log There are a bunch of requests, but no one for the video: 1741122617.179 109 ::1 TCP_MISS/200 17789 GET http://www.google.com/ - HIER_DIRECT/142.250.217.100 text/html

I think a simple way to test is: set a bad proxy configuration. python3 -m venv test
source ./test/bin/activate
pip install gradio
export http_proxy=http://a.random.proxy.address.com:911
export https_proxy=http://a.random.proxy.address.com:911
export no_proxy=localhost,127.0.0.1This is the test application, with another video import gradio as gr
import logging
logging.basicConfig(level=logging.DEBUG)
def create_interface():
with gr.Blocks() as demo:
gr.Video(
label="Input Video",
interactive=True,
value="https://download.samplelib.com/mp4/sample-5s.mp4",
sources="upload",
)
return demo
demo = create_interface()
demo.launch(
server_name="0.0.0.0",
server_port=7860,
)Run the app gradio test.pyAnd this are the logs: There are network requests failing because of the bad proxy setting, but the video request doesn't pass through the proxy so it works. |

Describe the bug
When I use Video with a URL as value, and run gradio behind a proxy, Video fails to download the url:
This code doesn't work:
The fail log is the following:
We thought it was a proxy misconfiguration. But looks like Video ignores our proxy settings (env vars http_proxy and https_proxy).
After changing our code to:
It started working (download_file uses requests to pull the file, looks like that one respects the proxy)

Reproduction
You need to be behind a network proxy. Configure the proxy and do:
