Add Video Tracks

Hi Joe,

Using Mojo portal 2.3.9.0, sql server 2005. Log in as administrator

I can add, play video tracks of any size without any problem. Thanks for helping with that.

New Problem:

The problem happens if I add a track of video of different file type in the same group. It throws error

We're sorry but a server error has occurred while trying to process your request.The error has been logged and will be reviewed by our staff as soon as possible. It is possible that the error was just a momentary hiccup and you may wish to use the back button and try again or go back to the home page.

Now I know which trcak is creating this problem and I want to remove this track that is creating the problem. There is no way I can edit this page to remove this track as I cannot view this page and select the option Edit this Page.

I have to go look into sql server for added track. Delete the record and everything works fine. But I don't want users calling me to do this everytime. I want them to be able to delete track that is causing problem. They are also admin to the site.

Please Suggest a solution.

Thanks

Re: Add Video Tracks

Start with Basic Troubleshooting to get the error details.

Post the error here but please don't post large chucks of your log, try to post just a single error with the full stack trace.

I suspect you just need to configure the mime type for the different type of file to prevent this error, or change the allowed file extensions from web.config to prevent users from uploading that type of file.

See also the troubleshooting section of the article Using the Audio and Video Players which explains about mime types.

Hope that helps,

Joe

Re: Add Video Tracks

Hi Joe,

The Tracks in the Edit Media Player is .mp4. and the File I added is .mpg. Config File is set to accept these files.

I know the problem. Its a wrong file. I want to delete this track. If I cannot view this page, I cannot select edit player. The problem is if I cannot edit this page, I cannot delete the track that is throwing error.

So I am looking at a solution of how to delete this track without going to backend database.

Thanks,

Again my intention is not to resolve this error I want to be able to just delete the track and add a good one from the user interface.

Thanks, Really appreciate any suggestion

Re: Add Video Tracks

The only thing I can do is add error handling for that in the next release. I was hopijng it would show a more specific error type than just Exception because I don't generally like to trap general Exceptions.

But in this case I'll just have to add code like

try
{

SetupScripts();

}
catch(Exception ex)
{

log.Error(ex);

}

to keep it from crashing the page.

So for now I guess you'll have to either configure your server to handle .mpg mime type which would solve it permanently and immediately or delete the track from the database.

I'll add that code in the next release to prevent it from crashing the page.

Best,

Joe

Re: Add Video Tracks

Note that if adding this file type to web.config isn't solving it you can directly configure mime types in IIS. In IIS 7.x in the very top node has an icon for mime types that will apply it at the server level though it can also be done at the site level. On my machine .mpg is configured as video/mpeg

Hope that helps,

Joe

Re: Add Video Tracks

I take it back this is not a server configuration problem and cannot be fixed by adding a mime type. After looking at the code (I didn't write this feature myself so I didn't know off the top of my head) I discovered that we were actually throwing an Exception from code if the file extension is not supported by the video player.

I've changed it to throw a more specific ArgumentException and added handling to trap and log that error so it won't crash the page. I've also added a more specific config setting for allowed file types so users will be prevented from uploading file types not supported by JPlayer in the Video and Audio features to avoid this error.

So this will be fixed in the next release but the only way to solve the problem at the moment is to delete the track from the database and advise users not to upload .mpg files. Sorry for the inconvenience.

Best,

Joe
