<div class="plain_line">It's rather a matter of the client than Icecast. Icecast blindy forwards</div>
<div class="plain_line">a bit stream. If your client can cope with a stream which changes bitrate</div>
<div class="plain_line">between MP3 frames, then you will be fine.</div>

<div class="plain_line">I just made a test: I created two files, one 32-bkps and another 128-kbps MP3</div>
<div class="plain_line">file. I setup ezstream-0.6.0 to stream them in a loop without reencoding into</div>
<div class="plain_line">an Icecast server, and used mpv (ffmpeg-based) and mpg123 (an independ MP3</div>
<div class="plain_line">decoder implementation) without any problems. I saved a stream reproducing</div>
<div class="plain_line">3 loops of the 2 files and verified that the stream size is roughly</div>
<div class="plain_line">equivalent to a tripple of a sum of the two file sizes. Hence indeed no</div>
