Hi,

Is the stream CORS enabled?

Can you play the stream with Chrome?

Can you share the stream url?

Hi Mehmet,

Your infrastructure is not configured very well, so the different browsers behave differently. We tested with Safari, Firefox and Chrome. Chrome worked well and the stream was playing.

Safari requested playlist.m3u8 and got redirected to master.m3u8. Then it tried an OPTIONS request for this resource and got response 501 (Not Implemented).

Firefox requested playlist.m3u8 and got redirected to master.m3u8 (same as Chrome and Safari). Then it received master.m3u8 and tried the first variant of the playlist: index_1_av-p.m3u8 but failed to download it - it got 403 (Forbidden).

Viblast Player fetches the stream entirely via JS and if you haven't configured CORS properly, it will fail to play the stream due to HTTP issues.

Best regards,

Stefan

Hi,

As we mentioned before, it seems like your server is not properly configured:

Please, find a comparison of the browsers requests/responses:

Firefox:

As you can see, the server responds different variant playlist. When the playlist is requested by Chrome, it contains variants with tokens. This is not true when the playlist is requested by Firefox.

Also, we tested with JWPlayer. It tried to use flash with Firefox, which is different from HTML5/MSE.

Best regards,

Hi,

It works with the other players because of the flash fallback used by them (JWPlayer). We tested with other pure HTML5 players and the result was the same. The issue is not related to the player itself, but  to the configuration of your servers. It is very aggressive. As far as I know you are not allowed to substitute the User-Agent header from JS. The better approach is to fix your servers.

Best regards,
