</span>The payloader is (usually) processing data that does not come over the<br>
wire, and in many cases it also needs to be able to look at the<br>
complete frame first before actually doing something.<br>
<br>
For the depayloader, e.g. rtph264depay should (or could) output<br>
individual NALs instead of complete AUs but as our decoder also work on<br>
frame-units this wouldn't help much. It would however be beneficial to<br>
change that in some situations, it just has to be done.<br></blockquote><div><br><br></div><div>Thanks. Since J2K supports tiling, tiles could be processed (encoded, decoded, etc)<br></div><div>before the entire frame is present.<br></div><br></div><br></div></div>
