https://community.intel.com/t5/Intel-Integrated-Performance/vm-time-sleep-wrong/m-p/787058#M2090 Hallo @ All<BR /><BR />i had the problem, that my video output hangs some times, so i looked up why, and i found this in avsync.cpp line 831:<BR /><PRE><SPAN style="font-family: Consolas;"><SPAN style="color: #880000;">vm_time_sleep</SPAN>(</SPAN><SPAN style="font-family: Consolas;"><SPAN style="color: #a000a0;">IPP_MAX</SPAN>(0,</SPAN><SPAN style="font-family: Consolas;"><SPAN style="color: #a000a0;">IPP_MIN</SPAN>(1,(</SPAN><SPAN style="font-family: Consolas;"><SPAN style="color: blue;">Ipp32s</SPAN>)((</SPAN><SPAN style="font-family: Consolas;"><SPAN style="color: navy;">ft</SPAN>-</SPAN><SPAN style="color: navy;"><SPAN style="font-family: Consolas;">st1</SPAN></SPAN>)*1000)))); </PRE>(i think this expession will always call vm_time_sleep(0&lt;=1) :D, but mostly with 0, so the output freeze)<BR /><BR />I replaced it with:<BR /><PRE><PRE>vm_time_sleep(IPP_MAX(0,IPP_MIN(DEF_TIME_TO_SLEEP&lt;&lt;1,(Ipp32s)((ft-st1)*1000)))); </PRE><BR /><BR />and now the movements are very softly, also in H264 and everything works fine. Also with this solution you can run (parallel) the windows Media player <BR />without some freezings.<BR /><BR />Best Regards Detlef<BR /><BR /><BR /><BR /><BR /></PRE> Thu, 24 Nov 2011 16:16:00 GMT detlef_stralaudynami 2011-11-24T16:16:00Z https://community.intel.com/t5/Intel-Integrated-Performance/vm-time-sleep-wrong/m-p/787058#M2090 Hallo @ All<BR /><BR />i had the problem, that my video output hangs some times, so i looked up why, and i found this in avsync.cpp line 831:<BR /><PRE><SPAN style="font-family: Consolas;"><SPAN style="color: #880000;">vm_time_sleep</SPAN>(</SPAN><SPAN style="font-family: Consolas;"><SPAN style="color: #a000a0;">IPP_MAX</SPAN>(0,</SPAN><SPAN style="font-family: Consolas;"><SPAN style="color: #a000a0;">IPP_MIN</SPAN>(1,(</SPAN><SPAN style="font-family: Consolas;"><SPAN style="color: blue;">Ipp32s</SPAN>)((</SPAN><SPAN style="font-family: Consolas;"><SPAN style="color: navy;">ft</SPAN>-</SPAN><SPAN style="color: navy;"><SPAN style="font-family: Consolas;">st1</SPAN></SPAN>)*1000)))); </PRE>(i think this expession will always call vm_time_sleep(0&lt;=1) :D, but mostly with 0, so the output freeze)<BR /><BR />I replaced it with:<BR /><PRE><PRE>vm_time_sleep(IPP_MAX(0,IPP_MIN(DEF_TIME_TO_SLEEP&lt;&lt;1,(Ipp32s)((ft-st1)*1000)))); </PRE><BR /><BR />and now the movements are very softly, also in H264 and everything works fine.
