NAME

SYNOPSIS

DESCRIPTION

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

-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.
