I'm running GStreamer gst-launch application on Windows with all the sources built with MinGW 32. Pipeline is very simple, I'm just showing an MPEG4 video coming from an IP camera: gst-launch-0.10 rtspsrc location=<RTSP URL> ! queue ! rtpmp4vdepay ! ffdec_mpeg4 ! d3dvideosink Everything went fine with 0.10.35 series, i.e.: gstreamer and plugins base 0.10.35, plugins good 0.10.30, plugins bad 0.10.22, gst ffmpeg 0.10.13, most important CPU load is around 3%. Then I upgraded to 0.10.36 series, i.e.: gstreamer and plugins base 0.10.36, plugins good 0.10.31, plugins bad 0.10.23, gst ffmpeg 0.10.13 and CPU load now is around 27%, but this is not sistematic. I mean, it can happen (rarely) that CPU load is around 3% as above, but very often it goes up to 27%. With further Investigations with Process Explorer I found out that in the worst case there's one thread that consumes up to 24% of CPU, while the rest goes normally. Since rtpmanager calls occurred often in the stack trace, I decided to recompile it with MSVC to get functions information and then the very strange behavior: with it CPU load is always OK, around 3% with no chance to reproduce the issue. Frankly speaking I have no idea of what's happening, may you please help me? Many thanks in advance, Matteo </body> </html>
