Peertube: Video not playing in Peertube player, but playing in Firefox player

[vtexier]

When I try to play my uploaded video, the Peertube player loads data (1M) but play nothing (black screen with loading icon).

If I use the direct download menu, the mp4 link play well in the Firefox player.

Can reproduce on your link, firefox nightly 63.0a1

In the console, after some time I get:

ICE failed, add a TURN server and see about:webrtc for more details
Error: "Connection error: Ice connection failed."

[rigelk]

The ICE server is mainly here to establish connection with other peers. It is not required to use the server's WebSeed, and as a matter of fact, the mp4 chunks get downloaded by the client normally from the WebSeed.

Since the server doesn't seed to have transcoding activated, it can be that the mp4 is faulty, but I'm not sure how to assert that. @Chocobozzz ?

[rezonant]

Same behavior in Chrome stable 67.0.3396.99 but no ICE errors visible (or any other errors). It is pulling chunks from WebSeed according to the Network tab, but no playback. WebSeed URL also plays back fine in Chrome.

https://tube.p2p.legal updated to PeerTube v1.0.0-beta.9.
Problem persist...
Issue modified to reflect that.

[poka-IT]

I open another ticket for a bug on another video in the same peertube instance, maybe the same bug but not sure: https://github.com/Chocobozzz/PeerTube/issues/785

[Chocobozzz]

This particular video was not transcoded, it's the reason why it fails to play :)

[vtexier]

The transcode option is now active and working well on the server.
Thanks for your quick answers !
