yuvcut

yuvcut − cuts a slice of a YUV4MPEG stream

yuvcut [-h] [-c [START]-[[+]END][,[+]START-[[+]END]]...] [-v]

Reads a YUV4MPEG stream from the standard input and outputs the selected ranges of frames to the standard output. A range can be specified using frame indexes (starting at 0) or using time code format [H:]MIN:SEC[.F] (optional hours, minutes, seconds and optional frame index). If start/end location starts with ’+’ it is interpreted relative to the previously specified location. If the start/end location is omitted then start/end of stream is assumed. The ranges must not be overlapping and they must be specified in order.

Cut the first 100 frames (frames 0-99) of the input stream:
yuvcut -c -99 < input.y4m > output.y4m

Cut the frames belonging to the second minute of the input stream:
yuvcut -c 1:00-2:00 < input.y4m > output.y4m
yuvcut -c 1:00-+1:00 < input.y4m > output.y4m

Cut 5 frames starting at 1:15:13:
yuvcut -c 1:15:13-1:15:13.4 < input.y4m > output.y4m
yuvcut -c 1:15:13-+4 < input.y4m > output.y4m

Cut two ranges:
yuvcut -c 10-23,40-76 < input.y4m > output.y4m

yuvcut was implemented by Johannes Lehtinen. It uses the mjpegutils library provided by the mjpegtools(1) package for reading and writing YUV4MPEG streams.
