Top Forums UNIX for Dummies Questions & Answers [Solved] Delete files with condition Post 302649419 by Skrynesaver on Thursday 31st of May 2012 09:57:12 AM

I may have misunderstood your requirements, but what's wrong with this bash "one" liner:

Code:
for i in directory/with/videos/files/*.mp4;do if [ ! -e ${i%.mp4}.avi ] ; then rm $i;fi;done

Or more explicitly:
Code:
for i in directory/with/videos/files/*.mp4;do # work through all mp4 files
   if [ ! -e "${i%.mp4}.avi" ] ; then # if no matching avi file exists
      rm "$i" # delete the mp4 file
   fi
done

yuvkineco

yuvkineco(1)							MJPEG tools manual						      yuvkineco(1)

NAME

       yuvkineco - revert 2-3 pulldown movie

SYNOPSIS

       yuvkineco [options] [-C PATH]
       yuvkineco [options] -O|N PATH

DESCRIPTION

       yuvkineco  reverts  to  original non-interlaced frames, from NTSC video which was film sourced and 2-3 pulled down.  Input fps code must be
       4(29.97fps), output fps code can be selected from 1(23.97fps) to 4(29.97fps). If 2, 3 or 4 selected, duplicated frames remain but they  are
       reverted  to  non-interlaced.  If input was non-interlaced only remove duplicate frames.  Interlaced frame detection may fail in conditions
       like:
	   Pull down cycle changed (video editing).
	   Low quality pull down.
	   Motionless scene.
       If -C PATH was specified, yuvkineco outputs 2-3 pull down cycle list to the file.  You can edit this file by hand and feed it to  yuvkineco
       with -O or -N option to correct mistake of 1st yuvkineco.  Try -C and see cycle list.
	 EXAMPLE #1: for 24p movie / automatically
	   lav2yuv 60i.eli | 
	       yuvkineco -F 1 | yuv2lav -f a -I 0 -o 24p.avi
	 EXAMPLE #2: for 30p/24p mix / automatically
	   lav2yuv 60i.eli | 
	       yuvkineco -F 4 | yuv2lav -f a -I 0 -o 30p.avi
	 EXAMPLE #3: for 24p movie / check and repair
	   lav2yuv 60i.eli | 
	       yuvkineco -F 1 -C 60i.23c | 
	       yuv2lav -f a -I 1 -o take1.avi
	   glav -F +n take1.avi  # check and edit 60i.23c
	   lav2yuv take1.avi | 
	       yuvkineco -F 1 -N 60i.23c | 
	       yuv2lav -f a -I 0 -o take2.avi
	 EXAMPLE #4: for 24p movie / check and retry
	   lav2yuv 60i.eli | 
	       yuvkineco -F 1 -C 60i.23c | 
	       yuv2lav -f a -I 0 -o take1.avi
	   glav -F +n take1.avi  # check and edit 60i.23c
	   lav2yuv 60i.eli | 
	       yuvkineco -F 1 -O 60i.23c | 
	       yuv2lav -f a -I 0 -o take2.avi

OPTIONS

       yuvkineco accepts the following options:

       -F FPSCODE
	       Set output fps code (default: same as input).

       -C PATH Specify 2-3 pull down cycle list file name to write.

       -O PATH Specify cycle list name to read with old yuv stream to retry.

       -N PATH Specify cycle list name to read with new yuv stream to repair.

       -S MIN  Use yuvycsnoise(1) as preprocessor and specify minimum threshold.

       -n LEVEL
	       Specify noise level of input (default: 10).  This affects both pulldown cycle detection and deinterlacing.

       -c THRESHOLD
	       Specify	threshold to decide pictures in 2 frames are same (default: 4).  yuvkineco compares several frames, searches pair of frame
	       they contain same pictures, to decide which frame should be dropped.  If THRESHOLD is 0, pair which has smallest difference will be
	       selected.  If 16, selected from pairs those have differences smaller than average.

       -i PERMIL
	       yuvkineco  deinterlaces	each  frame after 2-3 pulldown reverting process, specify how much pixels deinterlaced to decide to use or
	       not use deinterlacing result (default: 10).  If PERMIL is 10 and 1% or more of pixels deinterlaced, deinterlacing  result  will	be
	       used.   If  0, always deinterlacing result will be used.  If 1000, deinterlacing result will not be used, but deinterlacing process
	       will run on all of frames.  To disable deinterlacing process, specify negative value.

       -u      Set interlace information in header of output to unknown (default: non-interlaced).
