It’s been a couple of years now since I have been a digiKam user. I have been mostly happy with it (actually I don’t even use a lot of its features as my needs are not particularly advanced), but from time to time the Flickr would fail for no reason. Some time ago I needed to upload a lot of pictures and it started failing again, so I looked for some alternatives.

Apart from other apps I knew already and didn’t particularly like, I found dfo (Desktop Flickr Organizer), a GNOME application. It was nice, and it was easy enough to upload pictures to Flickr with it, but it felt weird. What I would like to have is some application to manage my gallery, with some option to upload certain pictures to Flickr. However, this applications is more like a local Flickr mirror with synchronisation options. I don’t want all my pictures in Flickr, even marked as private. I just don’t care, and I don’t want to wait for all synchronisation between the app and Flickr. Moreover, I feel kind of tied to Flickr using that, and I’d rather work in a more “agnostic” environment. So it was cool using it to upload the pictures I had to upload, but I wasn’t really going to keep using it.

At the same time, one friend suggested using Picasa to upload some pictures, so I gave it a try. I had tried it briefly in the past, and I remember that some things were nice, but for some reason it was never my gallery manager of choice. So, trying it again, and even using the synchronisation options for the Picasa web albums, somehow I got the same feeling again: it’s nice, but there’s something undefined that makes me not use it. I have to admit that the interface is really fancy and easy to use, and it works decently well, but I don’t completely like the way the synchronisation works, not to mention that I don’t want to be stuck with only Picasa web albums. Also, I’m not happy with it being proprietary, not available in the Debian repositories, and with that special, anti-integrated interface. Some things work much better than in digiKam (I’m especially thinking fullscreen/slideshow, which sucks pretty badly in it), but I still prefer digiKam overall.

As I wasn’t too happy with the alternatives, I decided to have a look at the problem with digiKam. It turns out that digiKam just uses the so-called Kipi-plugins for picture exporting and other things, and that there was a new version of it that fixed a couple of issues… one of them being a problem with Flickr upload. The package is not available on Debian unstable because we’re currently in freeze (unfortunately, that means that Lenny will ship without a functional Flickr-uploading Kipi plugin). However, I saw that the new package was actually uploaded to experimental, so I decided to give it a try. Not only it works like a charm, but the new version 1.6 reworks the Flickr export plugin completely, and now it’s much nicer. So I’m happy now, back to digiKam with a working Flickr export \o/. To install it yourself, make sure that you have this line in your /etc/apt/sources.list:

deb http://ftp.de.debian.org/debian/ experimental main non-free contrib

Then, update your available package list and install kipi-plugins from experimental, like this:

sudo aptitude update && sudo aptitude -t experimental install kipi-plugins

That should do it.

From time to time I like making panorama pictures. When I started several years ago, Autostitch was really popular, but it didn’t have a Linux version, which sucked. Actually, it still doesn’t. However, it worked under wine, so I just used it via emulation. It was very simple and worked ok.

Sometimes I’d look for alternatives under Linux (if possible, free) and I had seen a tool called Hugin. It looked complicated (at least compared to Autostitch’s select-pictures-hit-ok-there-you-go), and for some reason I never really used it. It probably wasn’t packaged for Debian or something like that.

A couple of days ago, though, I arrived from a trip where I took a couple of panoramas, and Autostitch had a quite suboptimal behaviour: it didn’t recognise one of my panoramas, and some others were completely destroyed perspective-wise. So I decided to give Hugin another go. And boy am I happy with it. It’s very easy to install in Debian, and although I had some problem with the path to enblend (apparently I had to specify the absolute path to it in preferences), everything worked fine. Selecting the points to join the pictures is not that hard, and actually has one advantage over Autostitch, namely that if it doesn’t recognise your panoramas automatically, you are giving “hints” about which points are the same in other pictures to Hugin, so it will work. Another advantage is that it has several ways of joining the pictures, which solved my second problem with perspective destruction :-)

Apart from the panorama pictures, I also had some videos... and one of them was recorded as “portrait” instead of “landscape”. So I needed a way to rotate the video. Fortunately, that was easy enough with mencoder (using command-line, though):

mencoder -vop rotate=2 MVI_2352.AVI -ovc lavc -oac copy -o MVI_2352.avi

I found the tip in some thread in Ubuntu forums, and had to look up the values for “rotate” in mencoder’s manpage:

0    Rotate by 90 degrees clockwise and flip (default).
1    Rotate by 90 degrees clockwise.
2    Rotate by 90 degrees counterclockwise.
3    Rotate by 90 degrees counterclockwise and flip.

In my recent trip to Copenhagen, I recorded a small video of the subway (it’s really cool, because it’s completely automatic, it doesn’t have drivers or anything). I wanted to edit the video to remove people that were reflected on the window, so I wondered if I could do that on Linux. I imagined it wouldn’t be trivial, but it was more frustrating than I thought. Maybe I’m too old for this.

The first thing I tried was looking in APT’s cache for “video editing”. The most promising was kino. I had tried that some time ago a couple of times, and I never made it to work, but I figured I would try again. Unfortunately, same result: I just can’t figure out how to import my videos. Maybe I’m just hitting the wrong button or whatever, but it’s really frustrating.

Second thing was having a look in the internet. I found the (dead and being rewritten?) Cinelerra, as always, and I didn’t feel like installing the old one from source, only to lose my time and not get it to work, so I just ignored it. Maybe they had it in debian-multimedia and wouldn’t have been a tough install after all. Anyway.

Next thing, I found some program called openmovieeditor. This one apparently worked, but I couldn’t figure out how to crop the image (or almost any other thing for that matter).

Next, some neat program written in Python, called pitivi. When I tried to run it though, it just said Error: Icon 'misc' not present in theme on the console and died. I later figured out that I had to install gnome-icon-theme for it to work (yeah, Debian maintainer’s fault). It’s funny, because on the webpage it says that it has some “advanced view” that you can access via the “View” menu… but I couldn’t find it. My menu only had one entry: “Fullscreen”. Great.

Oh, wait, there’s a gimp-gap. I could just import my animation in Gimp, crop the frames, and convert again to video. Easier said than done. I needed some programs that I didn’t have, and I wasn’t sure if they were so easy/quick/clean to install (sure, I could have exported to GIF animation and probably convert to video, I just didn’t want to lose so much color quality in the GIF step). Forget for now. At least I had the images, so if I could just turn them into a movie…

So, I started wondering if, given that I had decided to just crop, and especially now that I had a lot of images that were the frames, maybe I could just use some command line tool or something. So I found this tiny little program, images2mpg. Long story short, after installing some dependencies from source (that gave compilation errors, but luckily I could compile only the binaries I really needed) that program was completely retarded and didn’t even do what I wanted (it wanted at least one second between images, but I didn’t want a slideshow, just a normal movie from the frames). It looks some simple and it’s so buggy. Gah.

So I started wondering if I could just crop with mplayer... Hmmm… after a couple of problems (like documented switches that were not there and other crap), I ended up with this command line:

mencoder -vf crop=320:200:0:40 MVI_2160.AVI \
         -ovc lavc -nosound -o metro-crop.avi

That was reasonably quick and easy but it was so frustrating after all that lost time.

In any case, I ended up with the video I wanted, so I went to YouTube to upload it. When uploading, I realised that there was some option I had never seen: annotations.

YouTube annotations are really cool. They are like the notes on Flickr, but on a video :-D Actually I kind of wanted to make a note like that on this video, to show the automatic doors on the Metro station, so I was really happy to see that I could actually do it. And the interface is really easy to use and very clear. I really like it! You can see the result here:

EDIT: WTF? The annotations don’t appear on the embedded videos? You’ll have to go to the video page to see them, then…
