Like I said, the %nice is probably because that particular mode is run at low priority.
To know why it's run at low priority, I'd have to look deep into gstreamer.

lav2yuv
lav2yuv(1) MJPEG tools manual lav2yuv(1)
NAME
lav2yuv - Convert a MJPEG file to raw yuv
SYNOPSIS
lav2yuv [options] lavfile1 [lavfile2 ... lavfileN]
DESCRIPTION
lav2yuv converts an MJPEG video sequence described by a sequence of MJPEG video files and/or edit lists pointing to such files into the
simple uncompressed planar 4:2:0 Y'CbCr format, as used by mpeg2enc(1) MPEG encoder and image processing filters like yuvscaler(1) or
yuv2dfilter(1) or yuvdenoise(1).
Output is to stdout so that by piping the output of lav2yuv into a suitable pipeline it is possible to process and then encode or play back
video recorded in any of the mjpegtools MJPEG container formats: AVI, quicktime or edit lists describing editted versions of video held in
such files.
Mixing different files with different video formats is currently not possible.
The -S -T -D options are used for scene detection which is used by linux video studio.
OPTIONS
lav2yuv accepts the following options:
-m Force mono-chrome
-c Conceal frames containing corrupt MJPEG data by repeating the preceeding good frame.
-S list.el
Output a scene list with scene detection
-T num
Set scene detection threshold to num (default: 4)
-D num
Width decimation to use for scene detection (default: 2)
-o num
Frame offset - skip num frames at the beginning. if num is negative all but the last num frames are skipped
-f num
Only num frames are written to stdout. 0 means that all frames are processed.
-A width:height
Set/override the sample aspect ratio (SAR) emitted in the output stream header. Currently, the SAR is only auto-detected for DV
files, and guessed otherwise.
-P width:height
Set the intended/approximate display aspect ratio (DAR) for the stream. This value is only used to guess the SAR when it cannot be
detected from the input stream. The default DAR is '4:3' (corresponding to a standard TV screen); another useful value is '16:9'
(corresponding to widescreen TV).
-C chroma
Set output chroma (default: '420jpeg'). Currently, '420jpeg', '420mpeg2', '420paldv', '422' are available.
-x Exchange fields. Useful if the field order was reversed during editing.
