Pull Request Checklist

  • Target branch: Verify that the pull request targets the dev branch. PRs targeting main will be immediately closed.
  • Description: Provide a concise description of the changes made in this pull request down below.
  • Changelog: Ensure a changelog entry following the format of Keep a Changelog is added at the bottom of the PR description.
  • Documentation: Add docs in Open WebUI Docs Repository. Document user-facing behavior, environment variables, public APIs/interfaces, or deployment steps.
  • Dependencies: Are there any new or upgraded dependencies? If so, explain why, update the changelog/docs, and include any compatibility notes. Actually run the code/function that uses updated library to ensure it doesn't crash.
  • Testing: Perform manual tests to verify the implemented fix/feature works as intended AND does not break any other functionality. Include reproducible steps to demonstrate the issue before the fix. Test edge cases (URL encoding, HTML entities, types). Take this as an opportunity to make screenshots of the feature/fix and include them in the PR description.

Changelog Entry

Description

  • Fixes OpenAI-compatible multimodal video upload flow in chat by ensuring uploaded video/* files are injected into the outgoing message payload as video_url parts and media URLs are converted to base64 for both images and videos when needed.
  • Removes misleading upload-processing failure for video/mp4 by treating video uploads as completed for multimodal chat usage rather than forcing retrieval/text extraction processing.

Added

  • Support in process_chat_payload for injecting uploaded video files as {"type":"video_url", "video_url":{"url":...}} content parts.
  • Support in media URL conversion for both image_url and video_url items.

Changed

  • Renamed convert_url_images_to_base64 to convert_url_media_to_base64 and generalized handling from image-only to image+video.

Deprecated

  • None.

Removed

  • None.

Fixed

  • Fixed upload-time warning/error path where valid video/mp4 chat uploads were marked as unsupported for processing.
  • Fixed missing propagation of uploaded videos into OpenAI-compatible multimodal request content.

Security

  • No security behavior changes.

Breaking Changes

  • BREAKING CHANGE: None.

Additional Information

  • No new dependencies introduced.
  • Manual validation performed in a real Docker deployment with vLLM backend:
    1. Upload /home/shihan/Downloads/N1cdUjctpG8.mp4 in Open WebUI chat.
    2. Verify no upload failure toast for video/mp4 processing.
    3. Send prompt to vLLM-backed model.
    4. Confirm model returns accurate video interpretation.
  • "No sources found" may still appear for video-only turns because no RAG citations are attached; this is expected and unchanged by this PR.

Screenshots or Videos

  • Verified manually in local environment; screenshots/video evidence can be provided if maintainers request artifacts in-thread.
