Currently there is a restriction on size of file because it has to process the video in your memory and isn't saving content on the fly to disk but that is definitely something I can try to add moving forward
Good job on your release,
Curious, How is your version different from kagami or videoconverter versions, which were file conversions and they did not have streaming options, even though they had some patches who showed how to do it.
Does yours support streaming options so that the streams can be saved to file serially using streamsaver.js.
