automatic resize 2:35 or 2:40 to 16:9

[rjc862003]

is there anyway todo this only for the files that need it and not everything
most of my libary are 1920x800 but I would like to automatically resize them to 1920x1080 when required to avoid annoying black bars on my 52 inch LCD
id even settle for pan and scan
thx

It is exactly what this does:

# KeepAspectRatio: Some renderers like Panasonic TV internally rescale the video.
# This option sets the MEncoder custom options "-vf softskip,expand=::::1:16\/9:4"
# internally and set up keep aspect ratio for FFmpeg.
# Set this option to true to keep the original movie aspect ratio.
# Default value is false.
KeepAspectRatio =

# RescaleByRenderer: Works only for FFmpeg and together with KeepAspectRatio. Normally
# the renderer is rescaling the video. If set this option to false the UMS will do that.
# It can make better video quality but the CPU and bandwidth are more utilised and can
# produce jerking video on WiFi.
# Default value is true.
RescaleByRenderer =

In past we used for it "CustomMencoderOptions=-vf expand=::::0:16\/9:4,softskip" added to renderer.conf file:

So adding "KeepAspectRatio = True" should add black bars to video automatically, only in case it is for sure needed.
