Apply an MPlayer filter to the input video.

This filter provides a wrapper around most of the filters of MPlayer/MEncoder.

This wrapper is considered experimental. Some of the wrapped filters may not work properly and we may drop support for them, as they will be implemented natively into FFmpeg. Thus you should avoid depending on them when writing portable scripts.

The filters accepts the parameters: filter_name[:=]filter_params

filter_name is the name of a supported MPlayer filter, filter_params is a string containing the parameters accepted by the named filter.

The list of the currently supported filters follows:

• detc
• dint
• divtc
• down3dright
• dsize
• eq2
• eq
• fil
• fspp
• harddup
• il
• ilpack
• ivtc
• kerndeint
• mcdeint
• noise
• ow
• perspective
• phase
• pp7
• pullup
• qp
• sab
• softpulldown
• softskip
• spp
• telecine
• tinterlace
• unsharp
• uspp

The parameter syntax and behavior for the listed filters are the same of the corresponding MPlayer filters. For detailed instructions check the "VIDEO FILTERS" section in the MPlayer manual.

Some examples follow:

• Adjust gamma, brightness, contrast:

  mp=eq2=1.0:2:0.5

• Add temporal noise to input video:

  mp=noise=20t
