[GELÖST] Webcam Zeitraffer
Hallo zusammen,
ich soll für einen Kunden auf einer Website webcam-Bilder darstellen.
Jede halbe Stunde kommt ein Bild hinzu in einen fest vorgegebenen Ordner.
So soll z.B. ein Fortschritt bei einer Baustelle veranschaulicht werden.
So ähnlich stellt er es sich vor. Beispiel-Link
Wie mache ich das am besten? Gibt es ein Modul was sich da eignet?
Ich kenne natürlich gallery und album aber so eine Zeitrafferfunktion
gibt´s da ja nicht. Oder?
Hat irgendjemand damit schon Erfahrungen gesammelt?

Re: [GELÖST] Webcam Zeitraffer
So auf die kürze findet sich nur ein Shareware Script welches einiges kostet. Alles in allem müsstest du hier wahrscheinlich ein eigenes Plugin schreiben welches den Ordner ausliest und das JavaScript generiert welches für den Zeitraffer notwendig ist.
Ein Script (javascript) zu suchen dürfte hier jedoch recht aufwändig sein. Der PHP Teil ist noch das einfachere daran.

Re: [GELÖST] Webcam Zeitraffer
Meinst Du ein spezielles Shareware Script? Hast Du einen Link?
Ich glaube, ich brauche da eine fertige Lösung. Darf auch etwas kosten.
Muss der Kunde dann eben zahlen.
Eigenes Plugin schreiben etc. hört sich für mich zu kompliziert an.

Re: [GELÖST] Webcam Zeitraffer
Ich habe schon wieder ein wenig zu weit gedacht. Das Beispiel-Script welches du gepostet hat, eignet sich natürlich auch für deine Zwecke. Hier musst du einzig ein PHP Script schreiben welches dir die Bilder ausliest, sortiert und anschliessend als Javascipt ausgibt.

Re: [GELÖST] Webcam Zeitraffer
Ist wahrscheinlich nicht so schwer zu schreiben für jemanden der sich damit auskennt.
Tue ich aber nicht. 
Ich bin mehr so der Webdesigner. HTML, CSS, CMSMS alles schön und gut.
Wenn´s an PHP, Smarty, Templates von Modulen etc. geht, kriege ich immer schnell die
Krise.
Aber der Link ist super. Das scheint genau die Lösung zu sein die ich brauche.
Danke

Dafür haben wir ja hier auch das Board für "kommerzielle" Anfragen

Re: [GELÖST] Webcam Zeitraffer
Was lange währt...
Wenn´s noch wen interessiert. Hier ist das fertige Script im Einsatz. Link
Das von nockenfell empfohlene Script war eigentlich passend aber hatte keine Möglichkeit in das Bild zu zoomen (war vom Auftraggeber gewünscht).
So habe ich mich in einem php-Forum umgeschaut und da jemanden gefunden der mir das Script geschrieben hat.
Immer wenn ich hier auf ein Problem mit CMCms stosse, wurde mir hier bisher immer schnell und kompetent geholfen.
Seltsamerweise im kommerziellen Board (wo es ja was zu verdienen gibt) gab es keine Resonanz. - Komisch aber doch irgendwie sympathisch.

Re: [GELÖST] Webcam Zeitraffer
Danke für den Link. Schön das du eine Lösung gefunden hast.
Machst du das Script frei verfügbar oder ist das "Closed Source"? Deine Problemstellung haben wahrscheinlich noch weitere Leute.

If you would like to get website screenshots set up, you will need root access to your own server. Enable ALLOW_ALL_EXTERNAL_SITES so you can fetch any external web page. This is more secure now that we're using a non-web folder for cache. Enable BLOCK_EXTERNAL_LEECHERS so that your site doesn't generate thumbnails for the whole Internet. Instructions to get website screenshots enabled on Ubuntu Linux: 1. Install Xvfb with the following command: sudo apt-get install subversion libqt4-webkit libqt4-dev g++ xvfb 2. Go to a directory where you can download some code 3. Check-out the latest version of CutyCapt with the following command: svn co https://cutycapt.svn.sourceforge.net/svnroot/cutycapt 4. Compile CutyCapt by doing: cd cutycapt/CutyCapt 5. qmake 6. make 7. cp CutyCapt /usr/local/bin/ 8. Test it by running: xvfb-run --server-args="-screen 0, 1024x768x24" CutyCapt --url="http://markmaunder.com/" --out=test.png 9. If you get a file called test.png with something in it, it probably worked. Now test the script by accessing it as follows: 10. http://yoursite.com/path/to/timthumb.php?src=http://markmaunder.com/&webshot=1 Notes on performance: The first time a webshot loads, it will take a few seconds. From then on it uses the regular timthumb caching mechanism with the configurable options above and loading will be very fast. --ADVANCED USERS ONLY-- If you'd like a slight speedup (about 25%) and you know Linux, you can run the following command which will keep Xvfb running in the background. nohup Xvfb :100 -ac -nolisten tcp -screen 0, 1024x768x24 > /dev/null 2>&1 & Then set WEBSHOT_XVFB_RUNNING = true below. This will save your server having to fire off a new Xvfb server and shut it down every time a new shot is generated. You will need to take responsibility for keeping Xvfb running in case it crashes. (It seems pretty stable) You will also need to take responsibility for server security if you're running Xvfb as root. */ if(! defined('WEBSHOT_ENABLED') ) define ('WEBSHOT_ENABLED', false); //Beta feature.

Ferner den Ordner img, in dem die Baustellen-Kamara-Bilder für jeden Tag in einem seperaten Ordner gespeichert werden. Zuletzt eine Datei mit Namen css, in der aber nur drei Bildchen drin sind (Play, vor und Zurück-Pfeil, wie auf der Website zu sehen).
aus der Readme.txt: Folgendes bei der Installation beachten:
Der Ordner /cache/ muss beschreibbar sein, sprich die Rechte 0777
WICHTIG
Die Datei .htaccess erstellen, Inhalt ist "deny from all" (ohne Anführungszeichen) und in die Ordner /cache/ und /img/ kopieren
VERWEIS
Diverse Konfigurationsmöglichkeiten sind in der getFilesTT.php vorhanden
Das müsste alles sein. Viel Spaß beim ausprobieren.

Re: [GELÖST] Webcam Zeitraffer
Danke. Kannst du den Code nochmals neu einfügen. Wenn das ganze auf eine einzige Linie gepresst ist, ist er sehr schlecht lesbar.

-------====Website Screenshots configuration - BETA====-------
If you just want image thumbnails and don't want website screenshots, you can safely leave this as is.
If you would like to get website screenshots set up, you will need root access to your own server.
Enable ALLOW_ALL_EXTERNAL_SITES so you can fetch any external web page. This is more secure now that we're using a non-web folder for cache.
Enable BLOCK_EXTERNAL_LEECHERS so that your site doesn't generate thumbnails for the whole Internet.
Instructions to get website screenshots enabled on Ubuntu Linux:
1. Install Xvfb with the following command: sudo apt-get install subversion libqt4-webkit libqt4-dev g++ xvfb
2. Go to a directory where you can download some code
3. Check-out the latest version of CutyCapt with the following command: svn co [url]https://cutycapt.svn.sourceforge.net/svnroot/cutycapt[/url]
4. Compile CutyCapt by doing: cd cutycapt/CutyCapt
5. qmake
6. make
7. cp CutyCapt /usr/local/bin/
8. Test it by running: xvfb-run --server-args="-screen 0, 1024x768x24" CutyCapt --url="http://markmaunder.com/" --out=test.png
9. If you get a file called test.png with something in it, it probably worked. Now test the script by accessing it as follows:
10. [url]http://yoursite.com/path/to/timthumb.php?src=http://markmaunder.com/&webshot=1[/url]
Notes on performance:
The first time a webshot loads, it will take a few seconds.
From then on it uses the regular timthumb caching mechanism with the configurable options above
and loading will be very fast.
--ADVANCED USERS ONLY--
If you'd like a slight speedup (about 25%) and you know Linux, you can run the following command which will keep Xvfb running in the background.
nohup Xvfb :100 -ac -nolisten tcp -screen 0, 1024x768x24 > /dev/null 2>&1 &
Then set WEBSHOT_XVFB_RUNNING = true below. This will save your server having to fire off a new Xvfb server and shut it down every time a new shot is generated.
You will need to take responsibility for keeping Xvfb running in case it crashes. (It seems pretty stable)
You will also need to take responsibility for server security if you're running Xvfb as root.
*/
if(! defined('WEBSHOT_ENABLED') ) define ('WEBSHOT_ENABLED', false); //Beta feature. Adding webshot=1 to your query string will cause the script to return a browser screenshot rather than try to fetch an image.

Re: [GELÖST] Webcam Zeitraffer
Achtung, aufpassen:
"TimThumb by Ben Gillbanks and Mark Maunder"
--> Da gabs mal ne böse Sicherheitslücke, siehe (u.a.):
http://www.heise.de/security/meldung/Kr … 17795.html
das betrifft ja nicht nur Wordpress - dort ist es halt weit verbreitet.
--> check mal ob dein Script davon betroffen ist.
Servus,
Alex

Re: [GELÖST] Webcam Zeitraffer
wenn die htaccess wie beschrieben installiert ist scheint es kein Problem zu sein. So zumindest der Entwickler des Scriptes.
O-Ton:
Entwickler schrieb:
"ich habe erneut drüber geschaut, die Option die die Lücke ermöglichte habe ich zusätzlich deaktiviert, bereits auf dem Live-Server. Da aber die jüngste Version von TimThumb verwendet wird, bestand die Lücke nicht mehr. Selbst wenn sich eine neue Lücke auftuen sollte - wovon nicht auszugehen ist - kann der Angreifer nicht auf der Verzeichnis zugreifen, in welches jener eine schädliche Datei einfügen könnte, so dass keine Gefahr besteht."
