So you've cloned somebody's repo from github, but now you want to fork it and contribute back. Never fear! | |
Technically, when you fork "origin" should be your fork and "upstream" should be the project you forked; however, if you're willing to break this convention then it's easy. | |
* Off the top of my head * | |

2. In your local, add a new remote to your fork; then fetch it, and push your changes up to it | |
git remote add my-fork git@github...my-fork.git |

Locate the section for your github remote in the .git/config
file. It looks like this:
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
url = git@github.com:joyent/node.git
Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/*
to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma
You can get the list of supported formats with:
ffmpeg -formats
You can get the list of installed codecs with:
-#, --progress-bar
Make curl display a simple progress bar instead of the more informational standard meter.
-b, --cookie <name=data>
Supply cookie with request. If no =
, then specifies the cookie file to use (see -c
).
-c, --cookie-jar <file name>
File to save response cookies to.
