<div dir="ltr">Daniel, I won't make any points regarding DASH's fit with Icecast, but I wanted to address your statement that there is no purpose for adaptive streaming.<div><br></div><div>Cell phone connections are fairly terrible and inconsistent. Even if you have a solid signal on a 4G technology, you could walk around a corner and it will disappear. What works at 3mbit/s one minute might be 10kbit/s the next. Adaptive streaming is most certainly helpful in these situations, and is one of the reasons I do not exclusively use Icecast for the stations I work on.</div>

Hi Thomas,<br>
<div class="">> I wrote solid IPR evaluation for a reason.<br>
<br>
</div>It might be helpful to ask bitmovin as a starting point, they have<br>
released the reference code under LGPL:<br>
<br>
<a href="http://www.bitmovin.net/libdash.html" target="_blank">http://www.bitmovin.net/libdash.html</a><br>
<br>
The LGPL preamble says:<br>
<br>
"we insist that any patent license obtained for a version of the library<br>
must be consistent with the full freedom of use specified in this license."<br>
<br>
Personally, I don't see the point of adaptive streaming and the implied<br>
variation in quality. Either the quality you are streaming at is<br>
acceptable, or you are wasting bandwidth by streaming with too high a<br>
bitrate, perhaps due to an inefficient codec.<br>
<br>
I suppose the reasoning is that drops in quality are preferable to<br>
playback interruptions, but why tolerate either in a well-designed<br>
system? Adaptive streaming seems to say "we know the Internet is not<br>
really cable TV, but we are going to work around that by providing a<br>
cruddy picture for those times when available bandwidth does not align<br>
with our business model" :-)<br>
<br>
In the Icecast community, we might gain more by promoting Opus as a more<br>
efficient replacement for MP3 streaming, for example.<br>
<br>
Cheers!<br>
