ffmpeg to sound card

I never did figure this out. Maybe ffmpeg needs to be compiled w/ devices

ffmpeg –devices
linux:
[NULL @ 0x3171700] Unable to find a suitable output format for ‘–devices’
–devices: Invalid argument

mac:
[NULL @ 0x7ff53c810600] Unable to find a suitable output format for ‘–devices’
–devices: Invalid argument

The problem: latest java required TLS 1.2

Solution 1: edit java config to allow TLS1.1
issue: everytime we update java we would need to fix the java config

Solution 2: roll my own
failed miserably

Solution 3: install maridb to kubernetes

kmysql.homlish.net 10.11.168.244

had to connect to the pod to create users
CREATE USER ‘phomlish’@’%’ IDENTIFIED BY ‘****’;

add linux user

initial server install- we started this linux stuff before packages were using the group 101. We like to use that group so NFS shares work without mappings

Fix /etc/groups, move group 101 out of the way
grep 101 /etc/groups
like change systemd-journal:x:101: to systemd-journal:x:128:
groupmod -g 128 systemd-journal
groupadd -g 101 homeuser

add a generic user with a homedir & bash
useradd -m -s /bin/bash sr
add a user with no homedir & no shell
useradd -M -s /dev/null no-reply
add phomlish
useradd -g 101 -u 501 -md /home/phomlish -s /bin/bash phomlish

install certs in .ssh
add phomlish to all groups that have paul

add swarm
groupadd -g 1002 swarm
useradd -g 1002 -u 1002 -m swarm

give sudo
usermod -aG sudo phomlish

for wsl, powershell:

wsl –user phomlish
