Hello kdenlive-devel!<br><br>Sorry if the message is inappropriate for this mailing list.<br><br>My
goal is to edit AVCHD (h264/AC3) files in kdenlive. The videos are
generated from my Panasonic HDC-SD1 camcorder and are all interlaced or
1080i. For what is worth, I can play these files properly on my linux
box (Pentium D 3Ghz, Ubuntu 8.10 amd64, GeForce 9500 GT) using the
following combinations:<br>
<br> 1) mplayer + CoreAvc-for-linux<br> ~80-95% CPU w/ 2-cores. A/V out-of-sync but "corrected" with -mc 100<br> ./mplayer -vc coreserve -demuxer lavf file.m2ts<br> (have been unsuccessful at enabling CUDA support.)<br>
<br> 2) mplayer+ffh264vdpau (using mplayer HEAD revs)<br> ~30-40% CPU w/ 1-core only. No A/V sync issues. HW deinterlacing fine.<br> ./mplayer -vo vdpau:deint=2 -vc ffh264vdpau -demuxer lavf file.m2ts<br><br> 3) ffplay/ffmpeg (HEAD revs)<br>
~80% CPU w/ 1 core only. No A/V sync issue. No deinterlacing.<br> ./ffplay -skiploop 48 -threads 4 file.m2ts<br><br>I understand kdenlive uses ffmpeg and that VDPAU support in kdenlive is not ready <a href="http://www.mail-archive.com/kdenlive-devel@lists.sourceforge.net/msg01253.html" target="_blank">yet</a>.
However, I expect kdenlive to behave similarly to option (3) at least,
but unfortunately the playback in the clip monitor is pretty choppy and
nowhere near any of the options above.<br>
<br>I tried recompiling kdenlive's src/recmonitor.cpp and added the
skiploop and threads option (above) with no success; i.e. the behavior
is apparently the same as without it. I'm not sure if the change is
actually in effect and if that's the right place to add it.<br>
<br>Any help is appreciated.<br><font color="#888888"><br>Andre<br></font>
