A work in progress web tool to explore FFmpeg. Please log issues/suggestions. Made with svelte, xyflow, and ffmpeg.wasm.
Contributions are welcome! Take a look at the todo list below if you'd like to add a new feature, or the issues page if you want to try to fix a bug.
To run in dev mode:
npm install
npm run devI'm also looking for good FFmpeg examples. If you make a nice filtergraph in the tool, just hit cmd-s (or ctrl-s on windows/linux), and it will export a json file of your graph. Feel free to post those to the issues page for possible inclusion in the tool.
- Rendering on chrome doesn't work in multi-threading mode (it seems to fail on mp4s)
- Rendering progress bar
- "Cancel Render" button (thanks to @jwetzell)
- Disable/enable filters without removing them (thanks to @jwetzell)
- 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
- Handle audio and image output.
- Allow command to be editable
- Use commas to separate filters when possible
- Include some default fonts so text works.
- Allow gif as output
- Add more tests!
- MAYBE allow users to upload their own videos
- MAYBE make each part of the output command clickable, to highlight the corresponding nodes
- MAYBE add previews in the filter list itself
