What are all of the file extensions supported by FFmpeg

How would I go about getting a list of all the file extensions supported by FFmpeg for use in an ExtensionFilter used by FileChooser in JavaFX?

I am familiar with the "-codecs" and "-formats" options from FFmpeg, but these list the format and codec names which do not necessarily coincide with their file extensions.

e.g. (partial output from "ffmpeg -formats")

parsing aac and ac3 from the output of ffmpeg would work fine to create file extensions for those types of files, but matroska has ".mkv" file extension.

in python, this is trivial with pyav

python -c 'import av; print("\n".join([ formats + ":" + ",".join(extensions) for formats, extensions in (map(lambda format: (format, list(av.format.ContainerFormat(format).extensions)), av.formats_available))]))'

binka:binka
adp:adp,dtk
ilbc:lbc
sol:
fwse:fwse
s24be:
xvag:xvag
avif:avif
redspark:rsd
msf:msf
...

note: formats can have multiple names:

mov,mp4,m4a,3gp,3g2,mj2:mp4,mov,3gp,psp,isma,3g2,ismv,f4v,avif,m4b,mj2,m4a,ism

see also formats_available and ContainerFormat in av/format.pyx

JavaFX

in java, you will need to find a way to call libavformat.so

see also Where to get full list of libav* formats?

Based on the Gyan's answer, here's a python script I used to get all possible extension from ffmpeg, fot its muxers and demuxers:

import subprocess, re

ffmpeg = 'c:/ffmpeg/bin/ffmpeg.exe'

LINE_PATTERN = r' +\S+ +(\S+)'
EXT_PATTERN = r'Common extensions: (.+)\.'

# Get demuxers
output = subprocess.getoutput([ffmpeg, '-hide_banner', '-demuxers'])
lines = output.split('\n')[4:]

demuxers = {}
for line in lines:
  demuxer = re.findall(LINE_PATTERN, line)[0]
  
  info = subprocess.getoutput([ffmpeg, '-hide_banner', '-h', f'demuxer={demuxer}'])
  exts = re.findall(EXT_PATTERN, info)
  if exts:
    demuxers[demuxer] = exts[0].split(',')


# Get muxers
output = subprocess.getoutput([ffmpeg, '-hide_banner', '-muxers'])
lines = output.split('\n')[4:]

muxers = {}
for line in lines:
  muxer = re.findall(LINE_PATTERN, line)[0]

  info = subprocess.getoutput([ffmpeg, '-hide_banner', '-h', f'muxer={muxer}'])
  exts = re.findall(EXT_PATTERN, info)
  if exts:
    muxers[muxer] = exts[0].split(',')


# Write extensions
file_name = 'ffmpeg_extensions.txt'
f = open(file_name, 'w')

exts = set()
for ext in demuxers.values():
  [exts.add(x.strip()) for x in ext]
for ext in muxers.values():
  [exts.add(x.strip()) for x in ext]
for ext in sorted(exts):
  f.write(ext + '\n')

f.close()

print('Extensions written to file: ' + file_name)

There's no list directly available. You'll have to run

for input formats, ffmpeg -demuxers
for output formats, ffmpeg -muxers

Then for each entry, run

for input formats, ffmpeg -h demuxer=entry
for output formats, ffmpeg -h muxer=entry

Each format readout will show something like,

Muxer matroska [Matroska]:
    Common extensions: mkv.
    Mime type: video/x-matroska.
    Default video codec: h264.
...

or

Demuxer avi [AVI (Audio Video Interleaved)]:
    Common extensions: avi.
...

Then you can collect all extensions from the Common extensions entries.
