Manifest with multiple codec families

[AlexanderSlesarenko]

Hello, I use v 1.6.13, have manifest with h264 and h265 codecs:

i see that hls.js is jumping from one codec family to another. And that leads to bufferAppendError.

Does hls.js support multiple codec families in manifest? If yes - how to make it work without errors (maybe forbid switching between codec families?)
