Description

FFmpeg is a multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. It supports the most obscure ancient formats up to the cutting edge. No matter if they were designed by some standards committee, the community or a corporation. It is also highly portable: FFmpeg compiles, runs, and passes our testing infrastructure FATE across Linux, Mac OS X, Microsoft Windows, the BSDs, Solaris, etc. under a wide variety of build environments, machine architectures, and configurations.

Available versions (Euler, old software stack)

Legacy versions	Supported versions	New versions

How to submit a job

You can submit an ffmpeg job in batch mode with the following command:

bsub [LSF options] "ffmpeg [ffmpeg options]"

Here you need to replace [ffmpeg options] with ffmpeg command line options (please run ffmpeg -h for getting a list of all command line options) and [LSF options] with LSF parameters for the resource requirements of the job. Please find a documentation about the parameters of bsub on the wiki page about the batch system.

Example

As an example for an ffmpeg job, we are creating an mpeg movie out of a series of jpeg pictures.
