<p class="MsoNormal"><span style="font-size:11.0pt">My product involves streaming high bit rate (>15M) 4K video over a high-bit rate wireless link. I use LIVE555 proxy server on both sides. Based on reviewing the forum articles, I have made the following changes,

<p class="MsoNormal"><span style="font-size:11.0pt">What’s a good value to use here for 4K CBR at high-bit rate (>15M) ? 4K max uncompressed size is = 4096*2160*3=26,542,080. That seems somewhat excessive. I am not sure if using any other value would just be
totally arbitrary. Is there a guaranteed minimum compression that a H.265 encoder can guarantee irrespective of what the scene is ? If so, I can arrive at my buffer size based on that information.<o:p></o:p></span></p>
