A dynamic graffiti art character. A boy made of spray paint comes to life on a concrete wall. He sings an English rap song at high speed while striking a classic, energetic rapper pose. The scene is set under an urban railway bridge at night. The light comes from a single street lamp, creating a cinematic atmosphere full of high energy and amazing detail. The audio of the video consists entirely of the rap, with no other dialogue or noise.","",832,480,24,5.0]}],"links":[[29,4,0,16,0,"IMAGE"],[30,8,0,16,2,"SAMPLING_PARAMS"],[32,16,0,13,0,"VIDEO"],[33,18,0,16,4,"VIDEO_PARAMS"],[34,23,0,21,0,"IMAGE"],[35,24,0,21,2,"AUDIO"]],"groups":[{"id":1,"title":"Image-to-video input (first-frame-to-video)","bounding":[168.92390079062986,-653.2124402506535,560.8246471437027,407.4246532472182],"color":"#3f789e","flags":{}},{"id":2,"title":"Reference-to-video input","bounding":[-66.75175444110151,-225.24978633666066,805.4597228678848,554.7384400819777],"color":"#3f789e","flags":{}}],"config":{},"extra":{"workflowRendererVersion":"LG","ds":{"scale":0.8,"offset":[1240.4751945653188,770.6151743053379]}},"version":0.4} diff --git a/apps/ComfyUI-vLLM-Omni/web/main.js b/apps/ComfyUI-vLLM-Omni/web/main.js index da99b2539..9aba6260e 100644 --- a/apps/ComfyUI-vLLM-Omni/web/main.js +++ b/apps/ComfyUI-vLLM-Omni/web/main.js @@ -1,19 +1,153 @@ /** - * @file This file is intended to add dynamic fields to vLLM-Omni nodes - * based on widget (in-node form fields) and input (connection link) values and changes. - * However, this functionality is currently disabled/commented out. - * Because it introduces too much complexity, - * and it may even conflict with the current backend (Python) validation for unknown reasons (pending ComfyUI upstream fixes). + * @file Front-end extension for the vLLM-Omni nodes. + * + * Branding.
