IFME Distribution

What is this?

This command-line tool allow you encode video over network (via pipe).

Most encoder's support stdin and stdout, most popular tool is FFmpeg

How to use?

System Requirement

Ensure your computer meets the following specification:

1. .NET Framework 4.0 (Windows) or Mono Runtime (Linux)
2. Windows Vista and above or Ubuntu 14.04 and above
3. Intel Core i5 (1st Gen) or AMD AthlonII X2
4. 1GB RAM for handling RAW frame

Example

Internet Friendly Media Encoder Distribution - by Anime4000 (x265.github.io)
Version: 0.1.5579.20146 compiled on 11/Apr/2015 (AMD64/Windows RELEASE)

Lets you encode video over network, splits frames for each server
and equally distributes jobs to available workers in parallel.

Usage: ifmed [--help] [-s/-c] [-h ip] [-p port] [< "nope.avi"]
       ifmed [--help] [-s/-c] [-h ip] [-p port] [| ffmpeg.exe]

Options:
   --help   Display help
   -s       Run as server
   -c       Run as client
   -h       IP Address (Default: 127.0.0.1/All interface)
   -p       TCP Port (Range: 1024 - 65535. Default: 4000)
   -        stdin/stdout

Example:
   Client mode, distribute stream
   ifmed -c -h 192.168.1.2 - < "nope.avi"
   ifmed -c -h 192.168.1.2 -p 4001 - < "nope.avi"
   avs2pipe video "nope.avs" | ifmed -c -h 192.168.1.2 -

   Server mode, encode stream
   ifmed -s - | ffmpeg -i - nope.mp4
   ifmed -s -h 192.168.1.2 - | ffmpeg -i - nope.mp4
   ifmed -s -h 192.168.1.2 -p 4001 - | ffmpeg -i - nope.mp4

   Server mode, receive stream with specific time and duration
   ifmed -s - | ffmpeg -i - -ss 120 -t 200 nope.mp4

Note:
1. Server needs to be run prior to client.
2. Pipe over WAN is not recommended unless
   you have speeds exceeding 10mbps with VPN (encryption).
3. Sending RAW stream over network is not recommended unless you have 10Gbps.

Detailed Explanation

Server mode

Server mode is when a machine only does encoding. Before starting a client, ensure the server is running and awaiting connection.

FFmpeg:

user@host~# ifmed -s - | ffmpeg -i - nope.mp4

FFmpeg (listen specific interface):

user@host~# ifmed -s -h 192.168.1.3 - | ffmpeg -i - nope.mp4

FFmpeg (listen specific interface and port):

user@host~# ifmed -s -h 192.168.1.3 -p 4001 - | ffmpeg -i - nope.mp4

Or you can do more pipe! FFmpeg to x265!:

user@host~# ifmed -s - | ffmpeg -i - -pix_fmt yuv420p -f yuv4mpegpipe - 2> nul | x265 -p ultrafast --crf 25 -t psnr -o nope.hevc --y4m -

or encode specific start time and duration:

user@host~# ifmed -s - | ffmpeg -i - -pix_fmt yuv420p -f yuv4mpegpipe -ss 120 -t 240 - 2> /dev/nul | x265 -p ultrafast --crf 25 -t psnr -o nope.hevc --y4m -

Client mode

Client mode is the host that sending video data to encoding server. first you need a server running, see below.

To send a video (localhost default):

user@host~# ifmed -c - < "nope.avi"

Send to server:

user@host~# ifmed -c -h 192.168.1.3 - < "nope.avi"

With specific port:

user@host~# ifmed -c -h 192.168.1.3 -p 4001 - < "nope.avi"

Or send RAW (AviSynth) not recommended:

user@host~# avs2pipemod video "nope.avs" | ifmed -c -h 192.168.1.3 -p 4001 -

FAQ

Notice: 2> /dev/nul (linux) or 2> nul (windows) not to display text.

Notice: -ss is FFmpeg command for Start encode at specific second.

Notice: -t is FFmpeg command for Total time encode, require -ss.
