FFmpeg add a watermark to video

How to Add a Watermark to Video

FFMPEG filters provide a powerful way to programmatically enhance or alter videos, and it’s fairly simple to add a watermark to a video using the overlay filter. The easiest way to install ffmpeg is to download a pre-built binary for your specific platform. Then you don’t have to worry about including and installing all the right dependencies and codecs you will be using.

Once you have ffmpeg installed, adding a watermark is as easy as passing your existing source through an overlay filter like so:

ffmpeg -i test.mp4 -i watermark.png -filter_complex "overlay=10:10" test1.mp4

Basically, we’re passing in the original video, and an overlay image as inputs, then passing it through the filter, and saving the output as test1.mp4.

If you want to get the difference between two branches as a diff patch

If you want to get the difference between two branches, say master and branch-name, use the following command: git diff master..branch-name

If you want that same diff in a patch, because patches are handy, just add the output redirect: git diff master..branch-name > branch-name.patch

If you need to import that patch into something like Crucible then you'll need to get rid of the a and b prefixes that git adds: git diff --no-prefix master..branch-name > branch-name.patch

wuziq / building transmission

how to build transmission with openssl
brew install/upgrade openssl
homebrew tells you where it's installed and what LD/CPP flags to use. for me it was:
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
seems that transmission is also looking for OPENSSL_ROOT_DIR, so:
export OPENSSL_ROOT_DIR=/usr/local/opt/openssl
