Support alternative video tracks [RFC8216 (Section 4.3.4.2.1)]

Open enzanki-ars opened this issue 6 years ago • 2 comments

Description

Sources

I do not have a webhost I could use to the demo files I am currently using. The demo I am using with just 4 camera angles (will be 9 soon) already takes up 1.46 GB.

I might create a very simple test I could host on GitHub Pages if needed.

Copied below is my test files: (Independent testing via VLC and MPV show that the video tracks appear and can be switched to.)

There is a PR (#1128) for this. Maybe we could restart the conversation as it seems to have died down.
