I have two FLV files, File-A.flv is 11MB, File-B.flv is 50MB. Both are playing fine for public album. However, if I set album permission to Registered Users only, then File-A.flv plays fine, File-B.flv returns "HTTP/1.0 500 Internal Server Error" shown in Fiddler, FlowPlayer will show "200 stream not found...".

A few points to help debugging:
1. Both files play fine for public album, so it cant be Apache/php/FLV problem.
2. If log into the shell and swap the two files' names, and reset browser cache, then File-A.flv (now 50MB) gives problem. So it is solely related to file size, not user permission setting.
3. The "HTTP/1.0 500 Internal Server Error" is not from Gallery codes? Because I see you use "HTTP/1.1" whenever you return error in your php code.

Please help.

Al we do for permissions is drop a .htaccess file to prevent users from seeing the files. That appears to be working right since you swapped files name around.

What is in the Apache error logs?

The other thing that happens is when it's public, there's not any processing of the files through the file_proxy, but when permissions have been set, the files get processed through the file_proxy so now PHP is streaming that file out (at least that's how I believe things are still working) so it could also be a setting in PHP.

As Dave pointed out, finding out what the Apache error logs are showing will be helpful.

Bingo!
It was due to file_proxy and php setting. My php.ini had following line:

Quote:
memory_limit = 32M

I changed it to:

Quote:
memory_limit = 70M

After Apache restart, the File-B.flv of 50MB plays fine.

BTW, Apache error log had no trace of any problem. Maybe the reporting level is not set high enough to catch this error. I dont know.

However, using file_proxy brings up another question: I run "top" command in shell, I do see the MEM usage jumps to 50 whenever I view File-B.flv. My Linux box only have 256 RAM. Does this means my box can only support maximum of 5 simultaneous File-B.flv viewers?

Thanks guys.

Hm. What version of PHP5 are you using? On my dev box (PHP 5.3.2) I set my memory limit to 32M and played a 60MB flv file without difficulty. I didn't notice any excessive CPU usage :-/

I am using PHP 5.2.10

I get MEM spike every time I view the large FLV. Of cause you need to clean browser cache to view the effect.

I'm not sure what's going on there. If you have it working and you're not planning on hosting a lot of FLVs, I'd just leave it alone. PHP 5.2.10 is a year old so you could try upgrading to PHP 5.3.x to see if the problem still occurs.
