🌈 DESCRIPTION 🌈

ok so MP4SetTrackESConfiguration sets the elementary stream (ES) configuration of the track you specified, in the mp4 file you specified. periodt 💜

and the tea is: this info is codec specific. it's carrying the configuration that the given codec needs in order to decode the samples in that track. so like, no config, no decode, the vibe check fails 🫠 give her what she needs and she'll give you the samples back ✨
