I am looking for a standardized way to create and serve MP4 files made from a series of dynamically created canvas elements which I am currently able to do with h264-mp4-encoder on a serverless Vue app, but I wish to use a more recent and supported way. I have researched it and although I really want to use ffmpeg.wasm I am not sure how to integrate it in the context of a serverless Vue SPA and browser native APIs such as MediaRecorder do not seem to be best suited for my application. The very minimum would be to be able to control the frames per second (each frame added being a HTML Canvas element), the quality of the compression and if possible add metadata and allow for variable sized canvases (both features h264-mp4-encoder does not have).
