Re: [DVBCUT-devel] Qt4 port and further directions

My first aim was to port dvbcut to Qt4 and add multiple source videos. Nice to hear that some people still have free time. Not so nice to hear that you're wasting it. Well, in my opinion, anyway. This is an overview of what I already did: - apply qt3to4 - convert forms with uic3 -convert - port issues not covered by qt3to4 - use current libavcodec, libavformat and libswscale from system packages - remove the dependency of the q3support module Issues not covered by qt3to4 were: - QImage::scale() - QImage::scaled() - implicit cast from std::string to QString - implicit cast from QString to bool - lots of changes in method names Things to consider using QtCreator: - run setversion.sh to create version information The autoconf stuff and directories containing library code are not used. I have not yet created a new KDevelop4 project, because I do not have any experience with KDevelop. If anyone needs this, I will of course look into it. I would also look into new autoconf support, if anyone can give a good reason for doing so. Unlike others, an autoconf-based build environment will work on any system that has `make' and a decent shell. Is that reason good enough? You won't believe how much trouble I've already had with packages that use scons, cmake, or other evil^H^H^H^Hfancy stuff. These will be my next steps: - make sure it still runs on windows - remove all deprecations and compiler warnings - use models in all convenient places - use QListViews instead of QListWidgets - enable multiple input files - provide translations - find similar frames assistant - etc. I sent a mail to Sven Over some time ago, but he has not answered yet. If you like to see, what I have done in the dvbcut project, can please anybody reply to my and tell me how to proceed? Maybe the best course of action would be to take over maintenance of the package, if you're really willing and able to spend so much time on it. Unfortunately, I can't give you write access to the repository, since I'm not its owner. Only Sven can do that, and he's abandoned the project years ago. On the other hand, you don't have to use the repository on sourceforge. You don't have to use subversion either.

Hi. On 01/21/12 11:45, Reinhard Tartler wrote: Moreover, I found a problem in the Cmake files that you ship. They're part of the Qt4 patch. I don't use cmake for the Qt3 build, for largely the same reasons I got rid of the original scons build system. Well, maintaining two separate build systems is surely suboptimal. The cmake build system isn't my favorite either, but could you perhaps elaborate on the problems that it is imposing on you? I'm not familiar with cmake, so I can't maintain and support a cmake-based build system. I'm asking because my agenda on this is to get the Qt4 build integrated properly so that we don't have to update the patch on every upstream snapshot. And Qt3 is, unfortunately, not an option for use in a Distribution setting. Well, I don't want to maintain two versions, and it doesn't seem to be possible to write a program that works with both Qt versions (which says quite a lot about Qt, in my opinion), so a switch to Qt4 would be irrevocable - something I've tried to avoid so far.

Hi. On 01/21/12 13:23, Reinhard Tartler wrote: I see. What I understand is that the cmake build system is basically not blessed by upstream, and it was a mistake to settle on it in the debian package. Moreover, the qt4 patch in its current form only works with the cmake system. Well, what's blessed, as you call it, is the Qt3/autoconf combination. Qt4/autoconf would be okay, too, as long as everybody is aware that there's no way back once I incorporate the patch, and that the Qt3 version is effectively dead and buried at the same time. Therefore, you'd require the Qt4 port to work with the autoconf. It must also work on Windows/MinGW, as the Qt3 port does.

Re: [DVBCUT-devel] Simple help menu added
Hi! Here is the work by Claus reformed as a patch against SVN. I've removed all the whitespace changes that were apparently due to spaces changed to tabs by a rogue editor. Thanks, I had made it that far already. But when I ran the program, it dumped core at exit. Some kind of memory corruption, I guess, that needs to be investigated before I commit the changes. I've also made sure the license text exactly matches the license at the top of the source, and included the copyright and owner. Good idea. I've also added links to the project web site. Even better. Although that page is way out of date. I've tested the Help - About action, and I'm happy with it. No core dumps at exit?

Actually, configure is lying. liba52 is NOT missing - but it wants you to link with -lm (the math library) as well. This does not happen (at least on Linux) if you install liba52 as a shared library (in your case, there's only the static one). But you have to explicitly configure liba52 with --enable-shared for that (which I recommend anyway). I changed configure.in a little to take care of that. When it looks for liba52, it will now automatically include -lm, whether you need it or not.

Re: [DVBCUT-devel] translation of dvbcut
Hi! Martin Ereth wrote: In case we're going to use Qt's translation mechanism in the first place. That would be the easiest solution. But also the worst one. What if we want to add a gtk+ GUI one day? Or a *real* command-line version without the GUI overhead? The former is already on my wish list, by the way. What dvbcut badly needs is more separation of the functionality and the GUI. And a clean interface between them. If we use a Qt feature for i18n/l10n, we're going in the wrong direction. Unless we only translate the GUI portion (i.e. the 60-odd menu items). Besides that, everybody else uses gettext. I consider it a major design flaw that Qt provides its own translation mechanism, instead of proper hooks for gettext. If your Qt application uses any non-GUI libraries, for example, you end up using both mechanisms in parallel: gettext for the libraries and the Qt translator for the GUI. That's plain stupid, in particular since no serious application can do without third-party libraries these days. With regard to that, dvbcut is not an exception. -- Michael Tired Riepe [EMAIL PROTECTED] X-Tired: Each morning I get up I die a little - This SF.net email is sponsored by: Splunk Inc.

Re: [DVBCUT-devel] translation of dvbcut
Hi! Martin Ereth wrote: I read that dvbcut may be included at least in SUSE. To support this step it would be great when dvbcut is available in different languages. Yep. But that can't be done in some minutes: At first dvbcut has to be internationalized (i18n) and then it can be localized (l10n). For the first step it is neccessary to add a _() around every string that should be translateable. There have to be some little changes in main.cpp, too. When the strings are marked, a tool (gettext) extracts all the strings, that should be translated in a separate file. (This step can be done in an hour or two.) I'm quite familiar with the i18n process, as far as we're talking about ordinary C/C++ code. Been there, done that. What I *don't* know, on the other hand, is how you can internationalize the Qt stuff. Many texts, in particular all the menu labels, are currently specified inside the .ui files. I have absolutely no idea how to add the _() there. Or if there's any other mechanism. Or if that works with the standard (GNU) gettext. :( [...] Please tell me, whether you like dvbcut to be translatable. [...] Well, yes, of course! I think we already spoke about that here. But I didn't find a solution for the Qt/designer problem yet.
