Hey guys, I hope all is well. I haven't seen you online lately. I've been working with one of the gstreamer guys about the dv bug. Looks like we are making some progress. I've started work on the timeline playback. Turns out the scenelist is broken. Here's a quick look at what I'm thinking. <scenelist> <blank begin=3D end=3D /> //for gaps in the timeline. Probably play blackness. <video begin=3D end=3D offset=3D effect=3D src=3D /> //can be a/v <transition begin=3D end=3D src1=3D src2=3D type=3D /> <audio begin=3D end=3D offset=3D src=3D /> </scenelist> It will probably be much simpler than this to start but it would be good to have an idea of where we want to go. Let me know what you think. Cheers. Rob |

Hi everyone, A few updates on Kut. -Lucio has dv Kapture controlling a camera. -the gst engine has been integrated into the app. the callback issue has been fixed. -the configure.in.in and Kut/Makefile.am have been rebuilt. (Ruslan) the *.la dependencies are hopefully gone. -both monitors are now visible by default There are still some playback issues with the clip list but they should be worked out soon. Then on to the timeline playback. Finally. Unfortunately, I was accidently working on the cvs HEAD and not in NEW_ENGINE. So, I have made a new branch KUT_0_1 with the latest changes. I'm not really sure of the best way to get us in sync if you've been doing a lot of development in NEW_ENGINE. any ideas?? If most of your work has been in new classes it may be easiest to add them to a KUT_0_1 checkout. I just wanted to get these changes up while relatively stable. cheers, Rob |

Hi.
Here is a screenshot of my text application. Now I can show images on widget
using SDL. It is very fast. Now, I will start to work on frame decoder. It is
almost ready. To finish it I needed monitor, which I have now.

Hey fellas, Just wanted to give you an update on the engine status. I've been dealing with a strange bug for about a week trying to use the dvdec plugin. Even with a simple pipeline like:__ filesrc ! Dvdec ! Xvimagesink __ the application crashes sometimes and plays the other times. The only info from the crash is 'killed' and sometimes 'segentation fault'. I've done a core dump which has not been much help in figuring this out. I've got a few more ideas. I may also try to use the gst-ffmpeg plugin (I think it handles dv as well) and determine if it's just the dvdec plugin or something in the application. Hopefully, things will be working better soon. Cheers Rob |

I think it is the right way with current timeline design.
Decorator call the TimeLine method, which do all work with KRender.
KRender emits signal which is processed by TimeLine slot. After that,
TimeLine updates its area, sending icons array to the Decorator's update
method.

Hi all.
I force y brain to think a little about normal design of timeline objects.
I've started from decorators and track items.
Check XMI, any ideas will be good.

Lucio, Regarding your question yesterday about how to implement dv capture. I would suggest looking at writing a private plugin for our engine. There's a quick overview here. http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/sec tion-data-manager.html We would initialize it in the existing gstengine and have some application convenience functions there. That way there is no need to derive it from another class. Let me know what you think. Cheers, Rob |

I see.
I've checked Makefile.* in engine and plugins directories and found that it=
=20
use .la files of common use system libraries. Can you redesign these=20
Makefiles so they won't use .la of Qt and so on? As I think, you need .la=20
from libraries are builded in engine/plugins directory only.

Ok, I understand.

You've explained it above. I'd asked for how to use Engine with Kdenlive GU=
I.
I want to take Kdenlive version. It works fine with clips and timeline. I p=
lan=20
to insert your GST engine into Kdenlive. Then I'll test it and show to you=
=20
with Lucio. If all will be OK, I commit it into Axis/Kut CVS as the next=20
version of Kut. This is because I can catch a blinking bug with dragginf=20
clips on timeline. Sometimes it works, sometimes no.

Hi all. Rob, how to use your engine in kdenlive. As I understand, you just implement it like KRender. Is Engine look like KRender for GUI code?
