coreav probe - CoreAV

coreav probe FILE describes a media file as a JSON document on standard output: its container, its duration and each stream’s codec, size, timing and metadata. It reads MP4, MOV, Matroska, WebM and MPEG transport stream files. The document’s schema depends on the container:

Container	Schema
MP4 and MOV	`coreav.probe/1`
Matroska and WebM	`coreav.probe-matroska/1`
MPEG-TS	`coreav.probe-mpegts/1`

Examples

coreav probe input.mp4
coreav probe https://example.com/video.mp4
coreav probe --allow h264,aac --strict upload.mp4

--allow keeps only the streams whose codec is on the list, and --strict rejects the whole file (exit status 1) instead of dropping a stream. --ffprobe-compat prints the shape of ffprobe -of json -show_format -show_streams instead, limited to the fields that are checked against ffprobe.

Options

Describe an MP4, MOV, Matroska or WebM file as JSON

Usage: coreav probe [OPTIONS] <FILE>

Arguments:
  <FILE>  The file to probe

Options:
      --ffprobe-compat     Print the `ffprobe -of json -show_format -show_streams` shape, limited to fields checked against `ffprobe`
      --scan-fragments     Read every movie fragment so that fragmented streams get their durations (the default with --ffprobe-compat)
      --no-scan-fragments  Do not read movie fragments, even with --ffprobe-compat
      --scan-frame-sizes   Read the parameter sets and frame headers in every sample of each video stream for `video.scanned_size` (docs/design/frame-sizes.md). Reads the headers of every sample, not their coded data. For Matroska and WebM, the same pass also gives each stream's `duration`, `frame_count` and `bit_rate`
      --allow <CODEC>      Codecs to accept, comma separated (for example `h264,aac`); streams with any other codec are dropped. Default: every supported codec. Unsupported codecs (`other`) can never be allowed. Names of codecs a container cannot hold are ignored for that container
      --strict             Reject the whole file when a stream's codec is not allowed, instead of dropping that stream
  -h, --help               Print help
