<br>
Please send me the links to your streams. I'm interested in the audioquality.<br>

<pre style="white-space: pre-wrap; word-wrap:break-word; font-family: sans-serif; margin-top: 0px">Hello Jordan,<br /><br />I run a test stream in OPUS format.<br />I find the quality of OPUS way better at low bitrates then VORBIS.<br />Thus better quality at lower bitrates, but also on higher bitrates the<br />codec sounds good.<br /><br />Latency is lower, but for broadcasting a radio program for me at the<br />moment it is not that importend, so i did not test that really with<br />icecast (i did test opus low latency but with other applications:<br />fideliphone and teamtalk)<br /><br />Stream runs stable, my stream is a transcode made by Liquidsoap, from a<br />transparent ogg vorbis stream (The reason i'm doing that is because i'm<br />transcoing also to mp3, vorbis aacplus at different bitrates).<br /><br />Input is a live stream from a studio to my main icecast server, on this<br />server i transcode with liquidsoap. Then every stream is relayed by two<br />public ic
ecast
servers where listener clients connect to.<br /><br />Running this for quite a while now and it is stable for all streams.<br /><br />The is one downside on OPUS at the moment, there are not that much<br />clients able to play opus, plus on track change the stream makes a<br />little frame noticeable dropout. I do not know wheather this is cased by<br />liquidsoap or the player.<br /><br />The quys from liquidsoap say it is a problem how the player implemented<br />the opus codec (VLC).<br /><br />If you want, you can listen to my (dutch streams, day hours non stop<br />music, evenings programms hosted by a announcer) streams, send my a<br />private message and i will send you al my diffrent stream links, so you<br />can compare.<br /><br />Kind regards,<br /><br />Dennis<br /><br /><br /><br /><br />Op 31-5-2013 16:43, TheDarkener schreef:<br /><blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #729fcf; padding-left: 1ex;">Hi all,<br /><
br
/>I've been looking at opus lately as a replacement to vorbis and it sure<br />seems to me that, at least on paper, it is the 'next generation'<br />streaming codec. Has anyone been using opus as a streaming codec to<br />Icecast? If so, how do the following general characteristics compare to<br />vorbis?<br /><br />+ Quality<br />+ Latency<br />+ Bandwidth<br />+ Performance (on stream client and Icecast server)<br />+ Stability<br /><br />Also, what use case in your setup (voice only, music, pre-recorded files<br />vs. live input, ?) Any input is greatly appreciated. I understand there<br />is little support (compared to vorbis, anyway) for opus, but I'm hoping<br />to help change that at least a little bit.<br /><br /><br />Cheers,<br />Jordan</blockquote><br /><br /><br /><hr /><br />Icecast mailing list<br />Icecast@xiph.org<br /><a href="http://lists.xiph.org/mailman/listinfo/icecast">http://lists.xiph.org/mailman/listinfo/icecast</a><br
