HELP!! some arguments for my hosting provider, pls !! for deactivating this services!

tnx!

Hi,

Kaltura is awesome, isn't that a good argument?

I guess it'll be difficult to convince your hosting provider to enable these commands, since they can be source of security and performance issues in the case of shared hosting.
Even if you achieve to convince them, you will encounter other problems:
- When encoding, ffmpeg/mencoder/other (Kaltura's encoder) will use much CPU resources. Your provider won't like it, and the other users of your server neither. For example, ffmpeg with the -threads 0 configuration will make it use all CPU cores available. Fast encoding, but you won't let many CPU resources for other users.
- Streaming video uses much bandwidth (depending of the bitrate of course). Your provider must have set a quota traffic you can't exceed. It won't be long before this quota isn't enough anymore.

That said, I think you'd better turn to dedicated server or to Kaltura.com hosting service.
