Using Python's built-in defaultdict we can easily define a tree data structure:
def tree(): return defaultdict(tree)

Originall From: Posted 2015-05-29 http://ubwg.net/b/full-list-of-ffmpeg-flags-and-options | |
This is the complete list that’s outputted by ffmpeg when running ffmpeg -h full. | |
usage: ffmpeg [options] [[infile options] -i infile]… {[outfile options] outfile}… | |
Getting help: | |
-h — print basic options | |
-h long — print more options | |
-h full — print all options (including all format and codec specific options, very long) |
A quick guide on how to read/write/modify ID3 metadata tags for audio / media files using ffmpeg
.
FFmpeg has a free-form command line option that allows the user to specify key-value-pairs for encoding metadata. Let's take a look.
To list all global metadata tags for a media file, just set an input but no output file.
SELECT table, | |
formatReadableSize(sum(bytes)) as size, | |
min(min_date) as min_date, | |
max(max_date) as max_date | |
FROM system.parts | |
WHERE active | |
GROUP BY table |
