ffmpeg all options in brew
change owner of brew to root, which is common for files in /usr/local directory ( opposed to either /home or /Users )
sudo chown root /usr/local/bin/brew
and/or add the admin group
sudo chown root:admin /usr/local/bin/brew

Use ffmpeg and mp4box to prepare DASH-AVC/264 v1.0 VoD
See my DASH-IF presentation from October, 2014:
https://s3.amazonaws.com/misc.meltymedia/dash-if-reveal/index.html#/
1. encode multiple bitrates with keyframe alignment:
ffmpeg -i ~/Movies/5D2_Portrait.MOV -s 1280x720 -c:v libx264 -b:v 1450k -bf 2 \
-g 90 -sc_threshold 0 -c:a aac -strict experimental -b:a 96k -ar 32000 out.mp4
My input was 30 fps = 3000 ms. If it were 29.97, then a GOP size of 90 frames will yield a base segment
size of 3003 milliseconds. You can make the segment size some multiple of this, e.g.: 6006, 9009, 12012.

Adding a deploy user in Linux

(wherever it says url.com, use your server's domain or IP)

Login to new server as root, then add a deploy user

sudo useradd --create-home -s /bin/bash deploy
sudo adduser deploy sudo
sudo passwd deploy

And Update the new password

How to solve "sudo: no tty present and no askpass program specified" when trying to run a shell from Jenkins
Running shell scripts that have contain sudo commands in them from jenkins might not run as expected. To fix this, follow along
Simple steps:
1. On ubuntu based systems, run " $ sudo visudo "
2. this will open /etc/sudoers file.
3. If your jenkins user is already in that file, then modify to look like this:
jenkins ALL=(ALL) NOPASSWD: ALL
4. save the file by doing Ctrl+O (dont save in tmp file. save in /etc/sudoers, confirm overwrite)
5. Exit by doing Ctrl+X
6. Relaunch your jenkins job
