mediainfo_query: Query multiple parameters from a single MediaInfo section

In tidymedia: Media File Preprocessing and Metadata for the 'tidyverse'

Query multiple parameters from a single MediaInfo section

Description

mediainfo_query() uses the MediaInfo program to read several parameters from one section, and returns a tibble. To read parameters from more than one section in one call, use mediainfo_template().

Usage

mediainfo_query(file, section, parameters, names = parameters, typed = TRUE)

Arguments

file	A character vector of one or more media file paths.
section	A string. The name of the MediaInfo section to read parameters from.
parameters	A character vector of one or more MediaInfo parameters to read from section.
names	A character vector of column names, one for each element of parameters. The default is parameters. The function keeps the names as you give them, but removes spaces at their start and end.
typed	A logical. If TRUE (the default), numeric columns become numbers and empty values become NA. If FALSE, all columns stay strings.

Details

Give several files in file to get one row for each file. The first column, file, names the input file. The ⁠probe_*()⁠ functions read similar information with FFprobe.

Value

A tibble with one row for each input file. The first column is file, and then there is one column for each parameter.

A file that the function could not read gets a row of NA values. The function reads the other files, and then gives one warning that names the files it could not read. A file that reaches the time limit counts as not read; see with_timeout().

See Also

mediainfo_parameter() to read a single value. mediainfo_template() to apply a whole template. probe_all() to read information with FFprobe. get_duration() and the other ⁠get_*()⁠ functions for common single values.

Other metadata functions: get_duration(), get_frame_rate(), get_height(), get_sample_rate(), get_width(), mediainfo_parameter(), mediainfo_template(), probe_all(), probe_container()

Examples

video <- system.file("extdata", "sample.mp4", package = "tidymedia")
mediainfo_query(video, section = "Video", parameters = c("Width", "Height"))
