Looks like the Watch Live feature is reserved to the app only, on Mobile platforms. This is a screenshot from Chrome.

Looks like your using Android emulator that's why it's not working. Here is my screenshot from my Android phone using Chrome and it plays a live video gaming.

Looks like your using Android emulator

Actually, it's a real device connected to a PC, and using Vysor for interaction.

Can you please give me the link to the live streamer? I tried viewing a live feed from one of our other test accounts.

Here he's still live > link

I could reproduce it.

I think an Android 10 device must be used.

STR:

  1. Login to Facebook.
  2. Open a live stream (eg. https://www.facebook.com/soloz322/videos/1012296072476310/).
  3. Tap Play.

I've did some digging about this and there is just 1 error in console (No problem on Firefox Desktop Nightly, Chrome Desktop and Chrome Android).

resim HTTP “Content-Type” of “application/dash+xml” is not supported. Load of media resource https://video.fada1-8.fna.fbcdn.net/hvideo-cln-lla/_nc_ohc-HsDM1z30YWAAX9RqZmc/_nc_cat-105/v/rw4wQrEUt5ZGdkLBIqSdq/live-dash/dash-abr5/835233640593313.mpd?_nc_rl=AfAFUYeos9p2OPuO2Ic&ms=m_CN&oh=fec29d4bebe933f03f54b41f075bbc1b&oe=5FB4EA32 failed.

VLC also opens this link with no problem (this means there is no restriction, if fb restrict browser etc video will not play on vlc either). Probably fenix doesn't support mpd files.

Does fenix support mpd file type? How or where can i check this?

Edit: Oops, when i check deeper i can play this link in dash reference player on fenix. Soo fenix has no problem with video but has problem with its own video player? Idk.

This was mentioned in #media today. FWIW I can reproduce on Firefox desktop by spoofing my UA string as Firefox for Android.

They serve Firefox for Android dash+xml directly. If I spoof as Chrome for Android they serve MSE but something else is broken on their end so it appears as if it's loading indefinitely.

Firefox for Android in desktop mode works so consider that a workaround.
