I'm working on a site, which needs to have a feature of users capturing their opinions about a specific topic with their webcam, and uploading them to the server. After a short research, and viewing similar questions like this one I ran out of possibilities:
I cannot use Flash Media Server (out of budget)
I cannot use Red5, as the server where the app will be hosted is not able to build or install it. (our server guy told me that Red5 was last updated in 2007, and he got some errors which I include below (in case that someone would have an idea how to fix it) )
Are there any other possibilities?
red5 install errors:
xxyyzz#zzyyxx ~/red5 $ sh red5.sh

If you're looking for "production ready" solutions you're pretty much looking at flash media server. Other than that, try googling around for a PHP FLV encoding but I dont think you're gonna be able to stream to php and encode on the fly. Dunno, have to research and ask a PHP developer. Maybe post a modified version of this question with PHP tags.
Take a look at haxevideo, I've never used it but it could be what your after. http://code.google.com/p/haxevideo/
Teo! Have you tried to look for an online service (like Nimbb)? I used NImbb in one of my projects and it worked very well. I didn't need to spend time in programming and the technology they offer was very use for the end-users. This is a very

Moving from play 2.2.x to latest activator last night. Downloaded minimal 1.2.10, extracted it in program file (x86)\typesafe... and put the directory into the system path variable. cloned my repository, and when i executed activator run it downloaded the required modules and my app is up and running. All great so far. run works!
Then I tried to create a new app, and activator fails, with the following trace:

I've taken a look at several similar issues on SO and elsewhere. I've deleted .activator directory and retried, I've tried this process from behind a proxy and not, as well as offline (surely offline should work!), but it consistently gives the above error. activator ui gives the same error. I'm stuck and any suggestions would be appreciated. (Edit. tried with full activator download, rather than minimal, and I get the same error.)
Look for reasons it might be impossible to create or access 'C:\Users\admin.activator\1.2.10\templates\in
dex.db_6e0565f0c8826b17.tmp' ... maybe a permissions issue?
The failed check is for "is a directory" but that also fails if it just doesn't exist or can't be accessed.
I am trying to deploy a Play Framework 2.3 application to OpenShift.
I am following this example: https://github.com/JamesSullivan/play2-openshift-quickstart
Building and deploying the application is working (by that I mean the push to the git repository is working and the build is completing successfully), but during startup I see this error in play.log:

So it looks like the ${OPENSHIFT_POSTGRESQL_DB_URL} environment variable token-substitution is not working.
If I log in to my application, I see this via env (obviously I replaced the username, password, IP and port for the purposes of posting here):
OPENSHIFT_POSTGRESQL_DB_URL=postgresql://xxxx:yyyy#ip:port
I have also tried using the other environment variables, like OPENSHIFT_POSTGRESQL_DB_HOST but those too do not get substituted.
The relevant part of my openshift.conf looks like this:
db.default.driver=org.postgresql.Driver
db.default.url="jdbc:${OPENSHIFT_POSTGRESQL_DB_URL}"
db.default.user=myappuser
db.default.password=myapppassword
From the linked quickstart project, the following command is used to start the Play server (again, I replaced server-ip for the purposes of this post):
/app-root/runtime/repo/target/universal/stage/bin/myapp
"-DapplyEvolutions.default=true"
-Dhttp.port=8080 -Dhttp.address=server-ip
-Dconfig.resource=openshift.conf
You can see the openshift.conf file being referenced.
I tried a lot of things, eventually I found something that worked:
db.default.driver=org.postgresql.Driver
db.default.url="jdbc:postgresql://"${OPENSHIFT_POSTGRESQL_DB_HOST}":"${OPENSHIFT_POSTGRESQL_DB_PORT}/mydb
db.default.user=(((db-user)))
db.default.password=(((dp-password)))
The upshot is, it seems, you need to watch out very carefully for correct usage of the quotation characters.
It looks "wrong" (at first glance) since the last quotation character closes the string prior to the OPENSHIFT_POSTGRESQL_DB_PORT variable.
My OS is Win7 64 Enterprise.
I've just installed idea12 (ultimate), added Haxe plugin (0.5.6), installed haxe sdk 2.10win, also tried using 2.09win that comes with fdt.

This issue can't be in Haxe sdk as it compiles project fine under fdt (however, sdk-based autocomplete is not working, but I think it is not related to idea problem). Other project types (like java) are working fine with idea.
So, what shall I try to solve this issue? What does that exception mean?
Update: Installed idea 12.01 on WIN7 32 Professional, created new project - same exception happens. So, I conclude that this issue is not related to 32/64 bit OS or Java. This issue is not specific to idea version 12.00.
May be it is important that new project created by idea contains neither .hx classes, nor any build configuration files(like .hxml). I tried to create .hx main class and .hxml build for it, but idea still does not build project.
Changing run configuration to one of those files or to .swf result(built manually) or to cmd does not help(run option still not available).
I also tried to build with ant task, and it succeeded, but idea still can't build a project when I choose this option from menu.
The problem will be fixed in IDEA 12.0.2, thank you for reporting. As a workaround you can switch off 'Use external build' option in File | Settings | Compiler.
I cannot reproduce your error. Please try the usual reinstall, remove/add the Haxe SDK again, Invalidate Cache and restart (from the file menu).
If you can reproduce this problem with a fresh install, the best place for Idea support is their forum or create a new issue on their tracker http://youtrack.jetbrains.com/issues/IDEA?p=0&q=haxe
They have been very helpful to me in the past.
We are using hudson version 2.0.0.
Few days back after restarting hudson, i found that some of the jobs were missing.
Found that its due to the following NPE.

Upgrading to 2.1.2 didnt help. I removed all the plugins and re-installed, but in vain.
Has anybody else faced this?
Thanks,
Gayathri
OK I found the problem.
To fix this issue, I had to add the line that contains <publishers/> to each config.xml file in projects that failed to load (towards the end of XML file):
</builders>
<buildWrappers/>
<publishers/>
</project>
Somehow without this, Hudson/Jenkins barfs and hides in the corner crying.
Jobs will go missing from the dashboard when there is a parse error in the config.xml.
You can inspect these errors in Hudson / Manage Hudson / System Log looking for
Caused by: com.thoughtworks.xstream.converters.ConversionException: Could not call hudson.scm.CVSSCM.readResolve() : null :
It means the auto parameter migration failed and you have to edit the config.xml in the Jobs root by hand, the debug information in the log provides the offending line number. Commenting out the item usually works. Sometimes manual reconfiguring is needed.
Jobs will go missing from the history between restarts when the file build.xml is not generated in the build/<jobref> directory. If there is an exception in any plugin, it may cause the creation of this file to be skipped, and it will not show in history after a restart. Again looking in the log using Hudson / Manage Hudson / System Log is the quickest way to find the offending plugin. Disabling usually resolves the problem.
Please note that searching for "Missing Hudson Builds" will point to many different plugins/versions that all cause this problem. You should look in YOUR log to find what is causing the problem in YOUR installation, and only disabling the plugin that is causing YOUR problem.
A warning about "failed to generate build.xml" would save a lot of hours. I should open a bug on that.
I have a groovy application running locally on my desktop.
Apparently it runs error free. At least all unit tests I wrote are fulfilled.

Any hint why?
Thanks a lot in advance
I think you'll have to find the source of Gant.groovy and see what it's doing on that line. Apparently there is some problem caused by your project's specific configuration (since such a show-stopper bug would have been caught if it always occurred), but the error message does not contain much information.
Alternatively, you could try upgrading Grails to the latest version 1.1.1 if you haven't already.
