ov_set_video_meta: Set metadata tags in a video file

In openvolley/ovideo: Volleyball Video Utilities

Set metadata tags in a video file

Description

Requires that ffmpeg is available on your system path.

Usage

ov_set_video_meta(
  video_file,
  ...,
  movflags = FALSE,
  overwrite = FALSE,
  debug = FALSE
)

Arguments

video_file	string: path to the video file
...	: named values to set
movflags	logical: if TRUE, add "-movflags use_metadata_tags" to the command-line ffmpeg call. This allows arbitrary tag names to be used with mp4/m4v/mov video formats, but note that these may be stored in a manner that some video software cannot read. If movflags = FALSE, the supported video tag names (i.e. allowable names in the ... parameters) depend on the video file type
overwrite	logical: if TRUE overwrite the video_file, see Details
debug	logical: if TRUE, echo the ffmpeg output to the console

Details

This function creates a new video file with the specified metadata added. This is always a file in the temporary directory. If overwrite = TRUE, the original file is deleted and replaced with the new file.

Note that if movflags = FALSE, the supported video tag names (i.e. allowable names in the ... parameters) depend on the video file type.

Value

The path to the new video file, which if overwrite = TRUE will be the input file, otherwise a file in the temporary directory
