Converting MPD (MPEG-DASH) stream to m3u8
1er avril 2023, par veedoniI am currently doing research about how to convert MPEG-DASH stream to m3u8. So far I couldn't find anything helpful. What I know is that I need to decrypt mpd file using license key which I have and then convert it to m3u8. I have tried multiple times in last 7 days to do this but unsuccessful. I was using axios along with crypto, fetch, xml2js, m3u8stream and a lot of others tools. I am looking for directions where to start and examples of what to do because I feel like I'm lost. Anything would be helpful, Thanks !
