Server for Real Time Video Encoding

post #1 of 16
Thread Starter 
Hello,

I'm gonna make a PC for Real Time Video Encoding. The system will be under Linux. I need to encode MPEG to mp4 or flv. So I need to build a machine which will handle that. I don't know....I need fast CPU or GPU. And for the VC - I need regular or something like ATI FirePro (workstation), and for the CPU - again regular or server CPU like Xeon or Opteron?

Ask any questions...tnx!

Encoding is entirely CPU based unless you use GPU acceleration, but only a select few programs actually use GPU acceleration and any low end Cuda card (like a GTX 550Ti) will be more than enough for GPU acceleration so you don't need a workstation GPU or anything high end.

Now, what's your budget?

The budged is around $1,000.

and I'm talking about not 1 real time video encoding....I need several simultaneously encodings.

Is that budget for the entire rig? So PSU, RAM, HDD, case, mobo, CPU?

It's for the entire rig.

Ok, you could do a 2600K build for a grand, might go a bit over.

- 2600K

- Z68 motherboard
http://www.newegg.com/Product/Product.aspx?Item=N82E16813131792
or http://www.newegg.com/Product/Product.aspx?Item=N82E16813131806
or this open box http://www.newegg.com/Product/Product.aspx?Item=N82E16813131791R

- 16GB of RAM (1600MHz and the lowest timings you could find for the cheapest price; two 2x4GB kits)

- SSD if you can find one cheap, use for OS and uploading your work to for encoding; otherwise if you need the storage, two smallish 7200RPM drives and RAID 0 them.

Any good PSU, and cheap case.

If the encoding is going to be mission critical you need server hardware (for ECC). I do a lot of encoding on consumer hardware, and I constantly encounter an error on every few output files. It's not going to be cheap. MPEG, MP4, and FLV are not very descriptive on what you are going to be encoding, and therefore hardware requirements to encode in real-time can vary greatly.

The encoded video will be 720x576, 2 mbps. I need good quality - no drops..nothing like you said "crystal clear" (as can be with 2 mbps) smile.gif

That shouldn't be challenging to encode, whatsoever. My i7-970 encoded DVD stuff at well over 120 FPS, and always of a higher bitrate than 2mbps. You could get some low-end Xeon stuff to do that. An old LGA 771 Xeon system should do what you need without corruption within your budget. You also don't need much RAM for video encoding. It's purely CPU-intensive. You don't need any special video card. A server motherboard with onboard video would be fine. What format are you going to be encoding to? MP4 and FLV are containers.

To be exact I will encode 16 simultaneously video streams from DVB-S2 (satellite) to h.264 codec (flv).
