Thank you to Steve for the resolution suggestion - that seems to have<br>
cut the CPU usage by enough without destroying the quality. </blockquote><div><br>It worked for me so I figured it was worth a go. I read somewhere that the horizontal resolution of SD signals is actually very low - much lower than the 720x576 (or 704x576) that is theoretically possible.<br>
<br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> I am still<br>
quite disappointed by how much CPU decoding MPEG-2 takes - it is<br>
significantly more than MPEG-4, which is a much more compressed format.<br>
</blockquote></div><br>The mpeg standards are designed with decoding requirements in mind - so
mpeg4 requires a lot more horsepower to encode and yet is just as easy
to decode (or even easier as you are seeing in your case).<br>
<br></div></blockquote><br></div></div><div>Mpeg4 easy to decode?</div><div>H264 is part of mpeg4, could very easily argue that it's all but easy to decode. </div><div></div></div></blockquote><div><br>Good point, I forgot that h264 was part of mpeg4.<br>
