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.
| 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) |

Sometimes you may want to undo a whole commit with all changes. Instead of going through all the changes manually, you can simply tell git to revert a commit, which does not even have to be the last one. Reverting a commit means to create a new commit that undoes all changes that were made in the bad commit. Just like above, the bad commit remains there, but it no longer affects the the current master and any future commits on top of it.
git revert {commit_id}
Deleting the last commit is the easiest case. Let's say we have a remote origin with branch master that currently points to commit dd61ab32. We want to remove the top commit. Translated to git terminology, we want to force the master branch of the origin remote repository to the parent of dd61ab32:
