Ha ! nice trick with the SVG import/export smile

Having an "Image tool" has also been suggested previously. Admitedly, this type of image tool, would mainly serve for comparison with reference, so it might indeed make more sense to provide it with the "guides" feature rather than as a "drawing tool".

Maybe a menu under Observational Reference, before the list of svg, "Import an image", that would allow one to directly overlay an image file (jpg, png, bmp). Maybe even import an .svg as a guide on the fly…

It is a restriction of the OS, but Kinovea is compiled as a 32 bit program. When installed on a 64 bits OS, it runs in compatibility mode.

Bonjour,

Pour l'instant la fonction de capture est plus organisée autour du délai par rapport au direct qu'autour de l'enregistrement.

Il y a un concept important qui diffère peut-être des autres logiciels similaires : quand on enregistre, on enregistre ce qui passe à l'écran, pas ce que la caméra voit en temps réel.
(D'ailleurs vous pouvez modifier le délai pendant l'enregistrement, cela se verra dans le fichier final)

L'idée était de limiter les surprises et de permettre l'enregistrement « à la demande » même après que l'action soit finie.
Par exemple, si vous mettez le délai à 10s et que vous loupez le début de l'action, vous pouvez augmenter le délai à la volée et « rattraper » le bout d'action loupée.

Pour l'instant il n'y a effectivement pas de fonction permettant d'enregistrer une durée prédéterminée en un seul clic.
Dans votre scenario, il faudrait placer le différé à 20 secondes, et attendre que le saut arrive à l'écran, et démarrer l'enregistrement à ce moment. (Ou sinon tout mettre dans un gros fichier)

La fonction d'enregistrement n'est pas vraiment finalisée, et les choses peuvent encore changer…

There was some discussion about the PS3Eye a few weeks ago. I don't know if it works at the higher frame rates. Please try with 0.8.12 and report if it works or not.

You can add angles upon the capture screen to compare with a fixed value.
If you want to measure the exact angle you'll have to save the capture to a file and open it in a regular playback screen.

Hi,
I'll add the following line to the suggestion list :
- More control over naming convention for captured files.

More specifically, I think it would be nice to have a preference page where we can have full control over the naming convention, with a description string using format characters.
I recently came across an open source screenshot utility called ZScreen that has this kind of configuration page. (See screenshot).

Small update on this issue,
The cause of the error is that on a 32-bit system, we can't address more than 2GB of memory per process. (It's not actually running out of memory per se, it's running out of a way to address it. The ammount of physical memory in the computer is irrelevant).

Now this limit is a hard one, so the only solution is to prevent the buffers from taking up that much space.

I think the most straightforward way from the user point of view would be if the memory setting in the preference were to be understood for both screens combined ?
Other suggestions welcomed.

Thanks for the report and the log.
I have cut the long log from your message and pasted it in a file and attached it in bug 235.
I have reproduced this issue as well.

By the way, from reading the log, it would seem that you are also suffering from bug 234 ? (Trying to change capture resolution doesn't work: disconnects and reconnects at the default resolution.)

No problem smile

I've had some disconnect/reconnect issues in the past so there is probably something going on somewhere.
If you ever come across the issue again, try to find the reproduction scenario.

Pour l'export de fichier XML, je pensai bien à un menu avancé. Dans un sens tu as déjà réussi à avoir la possibilité ou non d'exporter les coordonnées des croix alors  je pensais que ça serait possible de faire la même chose avec la couleur des points ou la longueur de la ligne que tu traces, l'aire de rond

Oui c'est tout à fait faisable, mais c'est le rendre dynamique qui va être compliqué. Comme le script doit être embarqué à l'avance dans le programme, ça va être un peu tout ou rien, on pourra difficilement choisir ce qui est inclu dans le fichier final. (Sauf à générer un script XSLT dynamiquement à la volée ce qui est également envisageable).

Balou wrote:

Pourrait tu me préciser qu'elle est le logiciel le plus adapté pour modifier le fichier XSLT et éventuellement me donner le nom du ou des fichiers qui est responsable des export XML?

Personnellement j'utilise Notepad2 pour éditer les fichiers XSLT.

Ça fonctionne globalement comme ça :
- Au moment du clic sur le bouton d'export, on génère une description des dessins en XML sauce Kinovea.
- C'est l'équivalent du fichier .kva que l'on peut obtenir en faisant menu Fichier > Enregistrer… > Enregistrer uniquement les données des images clés.
- Ce fichier est ensuite transformé vers un autre XML (sauce Excel, OpenOffice, etc.) à l'aide d'un script XSLT.
- Le script XSLT décrit donc, pour chaque nœud de l'arbre XML Kinovea, la transformation à appliquer pour obtenir l'XML tableur.

Balou wrote:

Pour ne pas que j'ai de mauvaise surprise, qu'elle est la taille ou le temps maximal des fichier que kinovea peut gérer

Il n'y a pas de taille maximale, mais le mode « analyse » (quand les images sont décompressées en mémoire) dépend des préférences (page lecture/analyse) et de la mémoire vive disponible.

Derniére petite question quand compte tu implémenter la gestion du son dans kinovea?

Pas tout de suite tongue
Je pense que ce sera probablement relégué pour la série 0.9.x.

bonjour,
en voulant utiliser la version 8.12 j'ai ouvert ma webcam: logitech HD webcam c510 et j'ai eu un plantage avec ce message:
invalidArgument=la valeur 'o' n'est pas valide pour "selectedIndex'. Nom du paramètre: SelectedIndex. Pas moyen de la faire tourner...

Bonjour,
Est-ce que c'est arrivé en cliquant sur le bouton de configuration de la caméra ( « Choisir la source ») ? ou directement, sans intervention ?

Still, I'd like to understand the issue with the switching if possible.

Could you :
- Launch Kinovea, open capture screen. When your camera shows up try to switch configuration.
- After the switch fails and you are back to the 1600x1200 @ 5fps configuration, go to menu Help > Open log folder.
- Open the log.txt in notepad.

- Look for lines with "Connecting to device."
- Copy everything from the first list of possible configurations to the end.
Paste it here or as a comment in bug 234.

Thanks!

I am shooting with a Casio EX-FH100 that is capable of 120, 240, and 420 fps, as well as regular video. I would like to know if there is a way to put the frame rate into the program to adjust the timer accordingly, as well as adjusting the slider to play in real time.  Thanks!

Yes, go to menu Motion > High speed camera… and enter the capture frame rate.
Going back to normal speed from this type of slow motion video is not currently a planned feature for technical reasons: we would have to decode 210 frames or 420 frames per second (or more depending on the high speed settings) which is out of reach.

Maybe what could be done to mitigate this issue is to make the choice persistent somehow. So that when you select a specific configuration for a given device, the device always open up in this configuration when connected.

This configuration memorization feature may fix your switch problem because when reconnecting it would go with the preferred configuration directly.
