Hi Rolf, Does kdenlive still freeze on you? (I haven't modified the code in the last week) If so, can you try this and tell me what happens : in krender.h, change the lauchProcess() method so that it says this : void launcProcess() { m_socket.connectToHost("127.0.0.1", m_portNum); } This will stop kdenlive trying to start piave processes and it will simply try to listen on the relevant port instead. Now, start piave manually in the console (do it for all three instances) piave -p 6100 & piave -p 6101 & piave -p 6102 & Do you still get the freeze, or does this make kdenlive work for you?

That should be launchProcess() ;-) Cheers, Jason -- Jason Wood Homepage : www.uchian.pwp.blueyonder.co.uk |

I tried it a few time at it seems to work.

What does that mean? I'm not sure, but I'll throw a question over to the kde-devel list and see if anyone else knows. My suspicion that it is something to do with KProcess comes from when I first started using processes in Kdenlive. I initially used QProcess (the QT process class), but this always used to freeze kdenlive if you tried to open a file dialog. So I changed it to KProcess, and since that worked, I just assumed there were incompatabilities between how KProcess and QProcess worked. However, if kdenlive is freezing on your computer because of kprocess, then either there is a bug in kprocess that has since been fixed (what version of KDE is on your computer?) or there is something that kdenlive needs to do that I currently don't know about.

Can't it be something with the network connection, and/or piave? The freezing decreased since piave is not crashing so frequently. -- Cheers, Rolf *************************************************************** Rolf Dubitzky e-mail: Rolf.Dubitzky@Physik.TU-Dresden.de s-mail see http://hep.phy.tu-dresden.de/~dubitzky/ *************************************************************** |

You would never have seen kdenlive using QProcess, I never committed it to cvs. Kdenlive 0.2.0 uses KProcess. > > if kdenlive is freezing on your computer because of kprocess, then either > > there is a bug in kprocess that has since been fixed (what version of KDE > > is on your computer?) > > 3.0.0 I think that might be the issue here - I'll see if I can find out which modifications and bug fixes have happened since KDE 3.0.0 to see if this is a known issue. > > or there is something that kdenlive needs to do that > > I currently don't know about. > > Can't it be something with the network connection, and/or piave?

It could be the network connection, but you said that when you remove kprocess out of the loop (i.e., start all three processes from the terminal), kdenlive runs without freezing? This makes me think the problem is not network based unless it is some strange interaction between kprocess and qsocket. The fact that it kills your computer is also very suspicious - I don't do anything that low level ;-) Cheers, Jason -- Jason Wood Homepage : www.uchian.pwp.blueyonder.co.uk |

I have not studied that in detail, but it might be that > The fact that it kills your computer is also very suspicious - I don't do > anything that low level ;-) No, it doesn't hang the mashine (that would be very surprizing..). Only kdenlive hangs.
