 # Interactive FFMPEG Command Generator
 
 A work in progress web tool to explore FFmpeg.
+
+To run in dev mode:
+
+```
+bash
+npm install
+npm run dev
+```
+
+## Known Issues
+
+- Combining audio and video filters can fail
+- Rendering on chrome doesn't work in multi-threading mode (it seems to fail on mp4s)
+
+## Todo
+
+- [ ] Rendering progress bar
+- [ ] "Cancel Render" button
+- [ ] Disable/enable filters without removing them
+- [ ] Deal with duplicate parameters in filters (sometimes filters have a long and short option)
+- [ ] Add more help/documentation in the filters (there is more on FFmpeg's site that I could incorporate)
+- [ ] Add input options like seek and trim
+- [ ] Somehow figure out how to deal with complex filtergraphs
+- [ ] Add more sample inputs (at least need an image and an audio file)
+- [ ] Put filter options in a separate panel
+- [ ] Add filters that generate content
+- [ ] MAYBE add previews in the filter list itself
