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:
Upload /home/shihan/Downloads/N1cdUjctpG8.mp4 in Open WebUI chat.
Verify no upload failure toast for video/mp4 processing.
Send prompt to vLLM-backed model.
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.
