How to set movflags?

[felicemarra]

Hi.. I'm trying to stream via rtmp to social networks.
Everything works with facebook and node-media-stream but I have troubles with youtube and twitch.

I tested with classic ffmpeg and I saw that if I put -movflags faststart works well. If I miss movflags parameter doesn't work.

So I tried to set movflags with this function
await muxer.initOutput({ movflags: "faststart" })

but I'm not shure if the syntax is correct. Nothing changes about youtube streaming and I don't know how can I check if this flag is actually setted

Anyone can help me?

If you do a search in this repo, I think you will come across where I found something like the following (mostly untested on my end)

await mux.initOutput({ movflags: 'frag_keyframe+empty_moov+default_base_moof'});
