RAM Disk Advice (1 Viewer)

Logifuse.

Thank you sooooooooo much for those clear instructions mate. Have a great little RAMDisk set up now!

Unfortunately, I have had to rebuild my server with another motherboard since your last post - my original board had 12gb of RAM in it but the one I am using now only has room for 2 slots of RAM, so I have only got 4GB to use for time shifting. Hopefully, that should still be enough, otherwise I shall have to look at some expensive 8GB Ram Sticks

Anyway, the next bit is the bit that I have been dreading - setting up timeshifting to the RAMDisk. At the moment I says that it is 3.99GB in size with 3.94GB free. I have read the timeshifting part of the Wiki, but it is not absolutely clear which settings to use.

It says that I need to assign the space equally to each tuner (I have three, so approx 1.31 GB per tuner). I assume that I should leave the "Wait for unscrambled signal" "Wait for timeshifting file" and "Maximum free cards to try" boxes alone, which leaves "Minimum X files", "Maximum X files" and "File size X MByte/file".

Any clarification for this set up would be greatly appreciated.

Thanks

Alex

Hi Alex,

I re-jigged my RAMdisk as per logifuse's instructions as I was just using a FAT32 format as the RAMDisk program allows.

I just have the RAMDisk set as drive I: and all my timeshift files point to the root... I: and it seems to work fine. I have 8Gb of RAMDisk

I use ForTheRecord (where the default it 4 x 750MB files), so I'm not sure about setting the buffer in MPTV server.

For 'live' viewing, the disk space used per tuner = "Minimum X files" x "File size X MByte/file"

If you pause live TV, then the maximum space used per tuner = "Maximum X files" x "File size X MByte/file"

When you stop live TV the files are deleted, so in a single-seat system you can allocate more space per tuner because it's never going to be timeshifting on more than one tuner anyway.

Hi,

is there in the timeshift file only one channel or the full DVB mux?

One channel.

What will happen if one channel is record and another is watched in same mux. Will create MP a timeshift file during the record?

Yes, for the live channel.

Thanks very much for that. I am not sure I can entirely see why Live TV would have a lower authority to store programs information than when the paused button is pressed - is it for the simple reason that when you are watching live TV, you may want to skip back say a maximum 10 minutes to re-watch something, but if the phone goes and you pause for five minutes, you get this five minutes plus the original 10 minutes, giving a total of 15 minutes of skip back?

So, Just using my computer as a worked example, I have a standalone setup with 3.94GB of RAM free for timeshifting and three tuners. I have up to three client's that might be using the tuners in addition to the Standalone setup, so I would have to give a careful maximum to each tuner.

Hopefully this is the correct calculations:

3.94GB = 4,034MB of total RAM to share.
4,034MB / 3 = 1,344MB per tuner.

Am I correct in thinking that I should set time shift with a file size of 134MB, a minimum of say, 6 files and a maximum of 10 files?

If this is correct, would there be any advantage of having smaller files but allow more of them e.g. 67MB files but a minimum of 12 and a maximum of 20?

Sorry if this is getting a little complex.

Thanks again,

Alex

Yes, but you can set the min and max to the same value if you want to....

The 6+10 setup should be OK, but someone like porky996t who runs a multi-seat system might give you better advice in this situation.
