FSCK MPAA ! Spread the word about this : Spanish teacher gets fired after MPAA pressure
I finally finished backporting gnonlin to it's repository, cleaning it up, updating the website, putting more documentation online, etc... I've just put a pre-release online (v0.2.0-pre1). It's available on the GNonLin website. You're welcome to try it, and send me any bugs/inconsistencies you find out. I'll do a real release in 7 days if there's no major bug found.
So this means that, AT LAST, I'm hacking on python-pitivi !
On the side, I've been working with the Farsight (library for IM Voice and Video) team to "reverse" the OSCAR (ICQ/AIM/iChat) voice-and-video negotiation protocol. I'm not doing this out of interest, it's so I can call my folks back home for 0 euros :)
And I've finally found somebody who's doing a video motion-estimation filter (stand-alone, not lost in the middle of a video encoder) so I can finally put into code all these algorithms that have been taking the dust for the past year (slow-motion, motion compensation, temporal interpolation, HQ video scaling, ...). More about it once he's released it in Open-Source.
So I wasn't quick enough to reply for the room to rent in the Barri Gottic :( But I went to see the other place which is a little bit further (a good 20 minutes by foot from work, but which will be good for the exercise and the tan). This time I accepted the place way quicker :)
It's really great, I'm sharing it with Cristina - the catalan girl who owns the place - and Rachid, a french guy who works at Hewlett-Packard in the suburbs... and Kika a lovely little cat :) Well furnished, big bathroom (most important!), nice living-room, and all-in-all a very friendly 'ambiance'. And yes, I am forcing myself to speak spanish with Cristina (who also speaks english and french), and I'm starting to feel the results.
As you might have noticed, or not, I didn't release the next version of PiTiVi. Why, you might ask ? :) Well as I said before, I wanted to clean it up thoroughly so to make it easier to add new features, get rid of bugs, etc ... But I've been spending all of this past week finding out how much of the codebase was.. well... totally and completely un-evolve-able !!! The reason for that is in fact quite simple : the rest of the team was only interested in getting something nice for the final presentation (which we mostly managed to do), and it seems I was the only one wanting to make pitivi a true application (usable by everyone, and especially that carries on living after the end of studies).
SO... since I would have to rewrite almost everything (GUI-wise) from scratch, I am going to.. in python :) I've been wanting to do so from the start of the project, but for some reasons I won't evoke here, we decided to do it in C/GObject. Doing it in python is going to allow faster development, ease the addition of new features, and concentrate on the ergonomy and added value of a non-linear editor (instead of banging my head on stupid C related problems). And it's also time gnonlin goes back to it's separate repository and it's gst-plugin'able (which will definitely happen shortly). So for those not getting the message : the cpu-intensive parts of pitivi (GStreamer and gnonlin) are staying in C !
I'll be reviewing all of those ideas (and all the feedback I got on pitivi) at the beginning of this week with the rest of the fluendo team... stay tuned !
Wow, over a month without blogging. But I'm not dead, far from it.
End-of-Studies project [PFE]
So we did our final presentation of PiTiVi for school on Saturday 12th February. It went quite well and the teachers were more than pleased by the result, both from a technical and a commercial point of view. In fact I was just waiting for all this "school" period to end so I could get on some real PiTiVi hacking... far from constraints of studies and freeloaders.
The slides from the presentations are available here. They're in french , but I'm quite happy with the result I achieved using only OOo.
Change of Life
So that's it, Studies are OVER for me :) Well not entirely, I've still got to finish this internship at Fluendo, but I wouldn't call that studying...
The weekend after the final presentation of PiTiVi I went to Barcelona for the GStreamer summit. It was great finally meeting up with people you talk to every single day by IRC. A lot of decisions have been made which I won't go over again, but Stefan (ensonic) and I are working on the replacement for dparams to be included (hopefully) in 0.10 . It's quite interesting because both our projects (pitivi and buzztard) have heavy requirements on a form of dynamic parameters, and we've managed to come up with a lightweight method (in terms of cpu usage and lines of code to use it) to handle almost any use case. Stay tuned for more info, or check the mailing list. The weekend was also filled up with the usual eating and drinking...
Coming back from that extended weekend in barcelona I had 24 hours to move out of my room in Paris since I was letting it out. I will NEVER EVER AGAIN do that ! I trashed about half of the stuff I had in my room (12 square meters) and still managed to get a full car packed with all my stuff (furniture excluded)...
... and all of that in time to catch the coach to go to Brussels for the FOSDEM. The weekend was quite nice, I stayed at my best friend's place (who recently moved to Brussels to work), and it was great seeing him. I didn't go to many talks (apart from the usual Stallmann speech), but I spent most of my time talking to other hackers. The best was on sunday where I was able to hook up with Ronald (GStreamer plugins), Oyvind (GIMP/GGGL/Oxide) and Charles (MLT/Kino); we had lunch together and the talks revolved around getting all our various multimedia (and more specifically video editing/modification) ideas/projects/solutions working with one another. Great stuff in perspective !! Then salsaman joined Charles and I to present each other our software (lives, mlt, pitivi) and discuss our stroing/weak points.
After that weekend, I took one week of well earned vacation in my country house with the family and the girlfriend. The great part was that it snowed like hell (for two weeks) when usually it barely even snows in winter... Finally I arrived in Barcelona on saturday evening and started work at Fluendo on Monday.
I've been staying at Christian's place since, but been looking for rooms to rent. After visiting two places I think I've finally decided on taking one in the Barri Gotic (historical centre of Barcelona) where the owner is really easy-going, the living room really big and it's 5mins away from work.
The past three months have been ectict in pitivi development: lots of patches to have a presentable version for school. I've spent the last two weeks cleaning up the code (I still found some unused code !!!), moving functions/methods around, complying more to the OO programming paradigms and making it easier to add features in the future. I hope to have finished cleaning up everything by next tuesday in order to make a 0.1.2 release which will be the last pitivi release packed with gnonlin and using GStreamer 0.8 .
After that I'll put the gnonlin code back on it's independant cvs and pack it separately since more and more people want to use it for audio and/or video non-linear editing. I'll also add the necessary functions so they can be installed as gstreamer plugins.
Kiddo (the artist who made the new logo) is doing a long critic of almost every available non-linear editor with a beginner's point of view. His work (in french) is available here. Combined with Gnome HIG and other inputs I'll then refine the orientation of PiTiVi for the future, the main points being :
If you've got comments/ideas/features you'd like to see in a video editor, now is your time ! Mail me or come and chat on #pitivi or #gstreamer.
 : Yes I know commercial might seem somewhat irrelevant for open-source software. If you prefer we presented it for people who (in theory) didn't have a clue what our software does and how it works, so we had to present PiTiVi as if we were trying to convince customers (users).
A new pre-release is out, a bit delayed because casaxno left us for Stevens University next to NYC and so had other things on his mind, I had a very bad cold at the beginning of this week, and two others have been out skiing since last saturday (no comment).
This pre-release contains quite a few stability and ergonomy improvements, and a lot of other things that aren't really visible. I recommend using cvs versions of gstreamer/gst-plugins/gst-ffmpeg , it's more stable with those and works real faster.
v0.1.1.3 is available here.
Have fun and please report any bug you find.
I'm starting to make mini-releases of pitivi starting from today. Several reasons : it's easier to keep track of what versions worked, allows people to check if certain bugs were fixed, and allow more people to try pitivi between official releases.
Beware though that I don't check as many things/errors/coherence as for normal releases.
The pre-releases are available here starting with v0.1.1.1. Have fun :)
At long last, we've finally released the first version of PiTiVi. More info here.
Their still a lot of work to do, but I've got the feeling we're now on the good tracks.
Thanks to the GStreamer team for all their help.
I'm completely knackered, time to go out and eat a bite.
At Last ! I've managed to get rid of the remaining bugs in GnlOperation (the gnonlin effect handler) and now we can also put/move/cut.. use video effects in the Timeline. I also did a little cleanup in gnonling, and a (failed) attempt at trying to make gnonlin more "threaded". I'll have to look at that in 2-3 months when we get some heavier editing going on. 7 days left to check audio minimal editing and encoding and we'll be ready to freeze it for a release before Xmas.
Spent most of the weekend in bed because of a flu and a stiff neck. Both have gone, and I've got a lot more productive.
So... first post in my blog.
To sum up what I'm involved with, I'm head of project for PiTiVi a non-linear editor (NLE) that uses GStreamer as it's multimedia framework. This project was started as an "end-of-studies project" at the french IT I study in : EPITECH, but it will be carried on after the end of my studies (which'll be march 2005, yeah!).
In the past few days we've gone through the make install/dist/distcheck procedure for PiTiVi. I think we got most of it working, it'll take trials on other platforms/configuration to know if it really works.
I've also started making a list of the GStreamer plugins we use in the NLE, how "well" we can use them, and what the eventual problems are. The list is here. As I encounter new problems/bugs I'll update that list.
