From 6dc99338536ad45094a2513e8c86830244954a1c Mon Sep 17 00:00:00 2001 From: ydy0615 Date: Sun, 3 May 2026 19:14:55 +0800 Subject: [PATCH] refactor: remove FFmpeg dependencies and related video processing logic - Deleted FFmpeg related packages from package.json and package-lock.json. - Removed video transcoding and editing functionalities from FileContent.vue. - Simplified video handling logic and error management in FileContent.vue. - Added a clear button in MilkdownEditor.vue for clearing the editor content. - Enhanced UniverPreview.vue to clear detached popups and mount nodes on destroy. - Updated docBlockPlugin.ts to improve context handling for document blocks. - Cleaned up vite.config.js by removing cross-origin isolation headers. --- package-lock.json | 53 +--- package.json | 6 +- src/components/FileContent.vue | 460 ++---------------------------- src/components/MilkdownEditor.vue | 30 ++ src/components/UniverPreview.vue | 40 ++- src/plugins/docBlockPlugin.ts | 102 ++++++- src/utils/ffmpeg.js | 230 --------------- vite.config.js | 9 -
