coreav ffprobe

coreav ffprobe is experimental. Its values can differ from ffprobe’s for MP4, MOV and MPEG-TS files. The measurement page has the agreement of every key.

coreav ffprobe ARGS takes an ffprobe command line in ffprobe’s own syntax and answers it from CoreAV’s own probes. It prints the format, stream, chapter, program and packet sections that the container describes, in ffprobe’s writers (default, compact, csv, flat and json). It reads MP4, MOV, Matroska, WebM and MPEG-TS files, and https:// URLs. A command line outside what it implements, such as -show_frames, which needs a decoder, is refused in strict-safe mode and goes to the real ffprobe otherwise (strict-safe mode and the fallback).

Examples

coreav --strict-safe ffprobe -v error -show_format -show_streams -of json input.mp4
coreav --strict-safe ffprobe -v error -show_entries stream=codec_name,width,height -of csv=p=0 input.mp4

Use it in place of ffprobe

A link named ffprobe that points to coreav behaves as coreav ffprobe with the whole argument list, so a script that runs ffprobe can run CoreAV without changes. Under that name, only COREAV_STRICT_SAFE=1 turns on strict-safe mode, since every argument belongs to the tool:

ln -s "$(command -v coreav)" /usr/local/bin/ffprobe
COREAV_STRICT_SAFE=1 ffprobe -v error -show_format input.mp4

Options

coreav ffprobe --help prints a usage text of its own, not the full ffprobe option list:

usage: coreav ffprobe [OPTIONS] INPUT

Experimental: values can differ from ffprobe's for MP4/MOV and MPEG-TS
(measured on 1,315 files: of the keys outside the tags, 9 of 101
MP4/MOV and 35 of 157 MPEG-TS agree on fewer than 98% of files);
Matroska/WebM agree on 98% or more of files for all 101 keys.

The common ffprobe invocations, over CoreAV's own probes. Options:

Reads MP4, MOV, Matroska, WebM and MPEG-TS files and HTTP(S) URLs.

For untrusted input, set COREAV_STRICT_SAFE=1: anything else is then
refused (exit status 4). Without it, anything else runs the ffprobe
program on PATH instead (or the one COREAV_FALLBACK names), which is
FFmpeg's C code, and says so on standard error.
See docs/design/compat-cli.md.

The compatibility command’s design note has the grammar and the bars.
