Check Existing Issues

  • I have searched for any existing and/or related issues.
  • I have searched for any existing and/or related discussions.
  • I have also searched in the CLOSED issues AND CLOSED discussions and found no related items (your issue might already be addressed on the development branch!).
  • I am using the latest version of Open WebUI.

Installation Method

Pip Install

Open WebUI Version

0.7.2

Ollama Version (if applicable)

No response

Operating System

Centos7.9

Browser (if applicable)

No response

Confirmation

  • I have read and followed all instructions in README.md.
  • I am using the latest version of both Open WebUI and Ollama.
  • I have included the browser console logs.
  • I have included the Docker container logs.
  • I have provided every relevant configuration, setting, and environment variable used in my setup.
  • I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
  • I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
  • Start with the initial platform/version/OS and dependencies used,
  • Specify exact install/launch/configure commands,
  • List URLs visited, user input (incl. example values/emails/passwords if needed),
  • Describe all options and toggles enabled or changed,
  • Include any files or environmental changes,
  • Identify the expected and actual result at each stage,
  • Ensure any reasonably skilled user can follow and hit the same issue.

Expected Behavior

The video can be displayed normally on the chat page, and its height is not compressed.

Actual Behavior

I wrote a pipe function, and the content it ultimately returns to the frontend is as follows:

video_embed = f"""
        <video controls style="max-width: 100%; height: 100%;">
            <source src="{public_video_url}" type="video/mp4">
            Your browser does not support the video tag.
        </video>
        """

# Emit the video embed message
await state["emitter"](
    {
        "type": "embeds",
        "data": {"embeds": [video_embed]},
    }
)

return body

However, it is displayed on the frontend as shown below.

How can I make the video display correctly without its height being compressed?

Steps to Reproduce

None

Logs & Screenshots

None
