the patch should start with a similar line like:
diff --git a/avidemux/
Code: [Select] <- click , the code is now selected.
Right mouse click on selection, select copy.
Paste this into notepad++, gedit or similar editor (none
word processor = modifies the present code)
and save this file as update.diff (example)
place the saved file into top of avidemux2 (git of current avidemux)
now you can apply the patch
git apply update.diff
If al went fine you should be able to build the modified code.
A sample patch can be found here: slider position displayed time
for documentation purpose only
You should not use this after 2016/09/28, commit ab5ddb4 [nvEnc] provide probe function
. The code will evolve and will probably be not valid.
