# FFmpeg HDR Metadata Extractor
|
|
|
|
**FFmpeg HDR Metadata Extractor** is a HDR metadata extractor that uses **ffprobe** in order to retrieve HDR metadata from file, and generates ffmpeg parameters based on it.
|
|
Specifically it generates comman line parameters for three codecs available in FFmpeg:
|
|
- x265
|
|
- libsvtav1
|
|
- libaom_av1
|
|
|
|
# Pre requirements
|
|
In order to use this python script you need **python** version 3+ and **ffprobe** binary installed somewhere on your system.
|
|
## Linux
|
|
In **Linux** **ffprobe** usually came with **ffmpeg** package in your distribution.
|
|
## Windows
|
|
In **Windows**, you should search and install **ffmpeg** package by yourself, good starting point is ffmpeg official site: https://ffmpeg.org/download.html
|
|
|
|
# Usage
|
|
```
|
|
get_hdr_metadata.py [-h] -i INPUT_FILE [-s INPUT_STREAM] [-e FFPROBE_BINARY]
|
|
|
|
options:
|
|
-h, --help show this help message and exit
|
|
-i INPUT_FILE, --input-file INPUT_FILE
|
|
video file name from which hdr metadata needs to be extracted.
|
|
-s INPUT_STREAM, --input-stream INPUT_STREAM
|
|
video stream number in the input file, default 0.
|
|
-e FFPROBE_BINARY, --ffprobe-binary FFPROBE_BINARY
|
|
specify ffprobe binary to use, default - "ffprobe".
|
|
```
|
|
|
|
On Windows you probably need to specify exact ffprobe.exe binary location.
|
|
For example: `python get_hdr_metadata.py -e "C:\ffmpeg\ffprobe.exe" -i test.mkv`
