KCW + Webcam + Wowza media server not working
Thu, 12/17/2009 - 09:12
I am able to record on the webcam -- it shows the video preview, I even can back the recorded clip. I click through next to finish. The file shows up but it is 0 kb in size what gives???
Is it a permissions issue?
thanks

Wow... what a huge hassle.
Personally I think the symlink method is just too error prone -- I tried the SymLink in multiple ways and it just DID not work!!! I had no idea why I was getting these 0 kb files...
well I found the problem it had something to do with it not accessing the files properly (don't know why this would happen since I had the symlink in)
I ended up changing the php file by adding a $inputPath that points to my red5 server. My suggestion is to please just make this a configuration variable you can set somewhere in xml ... this is just so much easier than symlinking and less confusing / error prone.
File:
/var/www/kalturaCE/kaltura/alpha/apps/kaltura/lib/myInsertHelper.class.php
else if ($media_source == entry::ENTRY_MEDIA_SOURCE_WEBCAM)
{
// set $entry_fileName to webcam output file and flag that conversion is not needed
$webcam_basePath = $content.'/content/webcam/'.($webcam_suffix ? $webcam_suffix : 'my_recorded_stream_'.$kuser_id);
$entry_fullPath = $webcam_basePath.'.flv';
$inputPath = "/usr/share/red5/dist/webapps/oflaDemo/streams/".($webcam_suffix ? $webcam_suffix : 'my_recorded_stream_'.$kuser_id);
$inputPath.='.flv';
//echo "myInsertEtryHelper:: [$entry_fullPath]";
// for webcams that might have problmes with the metada - run the clipping even if $entry_from_time and $entry_to_time are null
{
// set $entry_fileName to webcam output file and flag that conversion is not needed
$webcam_basePath = $content.'/content/webcam/'.($webcam_suffix ? $webcam_suffix : 'my_recorded_stream_'.$kuser_id);
$entry_fullPath = $webcam_basePath.'.flv';
$inputPath = "/usr/share/red5/dist/webapps/oflaDemo/streams/".($webcam_suffix ? $webcam_suffix : 'my_recorded_stream_'.$kuser_id);
$inputPath.='.flv';
//echo "myInsertEtryHelper:: [$entry_fullPath]";
// for webcams that might have problmes with the metada - run the clipping even if $entry_from_time and $entry_to_time are null
if ( $entry_to_time == 0 ) $entry_to_time = null; // this will cause the clipper to reach the end of the file
// clip the webcam to some new file
$duration = myFlvStaticHandler::getLastTimestamp($inputPath);
$entry_fixedFullPath = $webcam_basePath.'_fixed3.flv';
myFlvStaticHandler::fixRed5WebcamFlv($inputPath, $entry_fixedFullPath);
$entry_newFullPath = $webcam_basePath.'_clipped.flv';
myFlvStaticHandler::clipToNewFile( $entry_fixedFullPath, $entry_newFullPath, $entry_from_time, $entry_to_time );
$entry_fullPath = $entry_newFullPath ;
}

Foobar you are the man. This fix is legit. Anyone having issues with the dubious webcam symlink structure needs to check this post out quick.
I see the following files in my /content/webcam directory:
