Hello all,<div><br></div><div> It is little bit off-topic, since it concerns OPAL 3.9.0 and above (e.g. trunk from svn), but, I can confirm, that H.263 codec support can be nicely without problems compiled under windows 7 32bit using VisualStudio2010 solution which is in OPAL 3.9.0 and above. (i did it). I tried also other codecs one can found in plugin directory of OPAL. Also PTlib and OPAL itself - both might be compiled directly from solution. </div>
<div><br></div><div>Codec plugins  I was able to make run so far is (capability list from openam):</div><div><br></div><div><div>   Cisco G.7231AR{sw} &lt;1&gt;</div><div>   Cisco G.7231A{sw} &lt;2&gt;</div><div>   G.711-ALaw-64k &lt;3&gt;</div>
<div>   G.711-uLaw-64k &lt;4&gt;</div><div>   G.723.1{sw} &lt;5&gt;</div><div>   H.261-CIF{sw} &lt;6&gt;</div><div>   H.261-QCIF{sw} &lt;7&gt;</div><div>   H.261{sw} &lt;8&gt;</div><div>   H.263-CIF{sw} &lt;9&gt;</div><div>
   H.263-QCIF{sw} &lt;10&gt;</div><div>   H.263{sw} &lt;11&gt;</div><div>   H.239 Capabilities &lt;12&gt;</div><div>           H.263{sw} &lt;1&gt;</div><div><br></div><div> however today I found out, that data transfer of H.263 is broken (looks like broken paylod in rtp data stream). H.261 works fine (i was testing openmcu together with openphone and myphone) and I could see this behavior on both - &quot;pure opal&quot; applications as well as mixed opal/h323+ (yes I know that opal uses h323+ or part of it). Right now I&#39;m not entirely sure whether it is caused by me or there is a bug. I have a plan to investigate it further.</div>
<div><br></div><div>Concernig plugin files, I was able to compile in the end (e.g. what you get from opal/plugins/ after build) :</div><div><br></div><div><div> g7231acm_pwplugin.dll</div><div> G726_ptplugin.dll</div><div>
 h261vic_pwplugin.dll</div><div> libavcodec.dll</div><div> Vic H.261 Video Codec.lib</div></div><div> ffmpeg H.263 Video Codec.lib</div><div> h263ffmpeg_pwplugin.dll</div><div><br></div><div>I had to download ffmpeg and compile it as well in order to build opal plugins for ffmpeg h263.</div>
<div><br></div><div>Concerning H264 plugin for OPAL - there is a problem around plugin-config.h file. Project uses it but according to svn it is not supported anymore (at least I saw the last one in OPAL 3.6.something (maybe even lesser version) and after that it was deleted from svn tree), so one can have x264 build under windows (which can be done also with little patience, but will have problems with opal plugin). - that&#39;s so far my observation. </div>
<div><br></div><div>Hope it helped!</div><div><br></div><div>Best regards,</div><div><br></div><div>   Vladimir</div><br><div class="gmail_quote">On Mon, Feb 7, 2011 at 12:01 PM, Simon Horne <span dir="ltr">&lt;<a href="mailto:s.horne@packetizer.com">s.horne@packetizer.com</a>&gt;</span> wrote:<br>
