Listening issue - Windows 7 Web browsers

[silverkorn]

Not sure if it's related with this issue #8 but listening to streams broadcasted by Icecast 2.4.2 is taking way too long before starting natively on any Web browsers on Windows 7. Note that audio players/tools such as FFplay and VLC works properly under this OS.

This issue doesn't seem to happen using an Icecast 2.4.0 (KH branch) server.

Thanks!

This is not an issue with Icecast but sounds a lot like configuration specific. Note that you can try to use a bigger burst on connect in the Icecast config (remember to increase the overall buffer too).

And no, this is completely unrelated to #8, as that is about sending content to Icecast.

If it turns out that increasing burst will not help, please comment again here, and I'll have another look at it.

This was already tested from 64k to 32k.
Did you have a chance to test on your end?

[ePirat]

What do you mean by "from 64k to 32k"? That would be making the burst smaller, which is the wrong thing to do in this case, as you want a bigger buffer, so the browsers player buffer fills faster and playback starts faster.

And please provide a few more details:

• Which format are you streaming in?
• Which Bitrate or Quality?
• Which web browser(s) did you try this with?
• If possible, the url for the problematic stream

Hmm... I thought that burst was about a buffering feature that by lowering it, it would start faster on the listener's end.

Unfortunately, the correlation that it worked properly on 2.4.0-kh and not on 2.4.2 with the same configuration file and this only happens on Windows 7 (SP1) OS, on any Web browsers (IE11, Chrome, Firerox).
Windows XP SP3 (Any browsers) and Windows 10 (Tested on Firefox & Chrome) were tested on 2.4.2 and it worked properly...

At first I thought it would be because of the network but I tried on a direct access to the Internet without proxies/firewalls and the same behaviour happened.

As by relating the issue #8, I was guessing that it might be a problem through a HTTP header that Windows 7 SP1 might not operate properly under any browsers.

Hope this helps.
Thanks!

Closing this as I am unable to reproduce and so far this is the only report we got about this.
Note that neither MP3 nor AAC are officially supported formats so it could be that it works better in kh.
