Ffmpeg

FFmpeg is a free and open-source project consisting of a vast software suite of libraries and programs for handling video, audio, and other multimedia files and streams. At its core is the FFmpeg program itself, designed for command-line-based processing of video and audio files, and widely used for format transcoding, basic editing (trimming and concatenation), video scaling, video post-production effects, and standards compliance (SMPTE, ITU). FFmpeg includes libavcodec, an audio/video codec library used by many commercial and free software products, libavformat (Lavf), an audio/video container mux and demux library, and the core ffmpeg command line program for transcoding multimedia files. FFmpeg is published under the GNU Lesser General Public License 2.1+ or GNU General Public License 2+ (depending on which options are enabled).

The name of the project is inspired by the MPEG video standards group, together with "FF" for "fast forward". The logo uses a zigzag pattern that shows how MPEG video codecs handle entropy encoding.

FFmpeg is part of the workflow of hundreds of other software projects, and its libraries are a core part of software media players such as VLC, and has been included in core processing for YouTube and the iTunes inventory of files. Codecs for the encoding and/or decoding of most of all known audio and video file formats is included, making it highly useful for the transcoding of common and uncommon media files into a single common format.

Frameserver

With this, you can offload Adobe Premiere Pro encoding to an external server with ffmpeg installed.

• Install ​Debugmode FrameServer, ​Avisynth (32-bit), and ​ffmpeg (32-bit static build).
• Create an Avisynth script named frameserver.avs by opening a text editor and adding the following (assuming your working directory is c:\encode):

   AviSource("c:\encode\output.avi")

• Open Premiere, select your sequence, and choose "File > Export > Media" (or hit Ctrl+M)
• Under "Export Settings" choose "Format: DebugMode FrameServer" and make sure "Export Video" and "Export Audio" are both checked. Give your file the same name and path as shown in your Avisynth script (output.avi in c:\encode for this example).
• The FrameServer setup window will appear. Choose "Next".
• Now you can encode with ffmpeg using your Avisynth script as an input. Windows machine:

   ffmpeg.exe -i frameserver.avs -f mpegts tcp://192.168.1.100:1776

Linux server:

   ffmpeg -i tcp://192.168.1.100:1776?listen -c:v libx264 -preset medium -crf 23 -pix_fmt yuv420p -vbr 4 output2.avi
