Find input audio rate beforehand thus:
ffmpeg -i input.mp4
Assuming input audio rate 44,100 Hz, this command will do the job:
ffmpeg -i input.mp4 -af asetrate=44100*3/4,atempo=4/3 output.mp4
The factor of 3/4 will change most female and “skinny” (chipmunk) voices into male and “fat” voices. Use 4/3 for the opposite:
| # Vncserver service file for Debian or Ubuntu with systemd | |
| # | |
| # Install vncserver and tools | |
| # e.g. apt-get install tightvncserver autocutsel gksu | |
| # | |
| # 1. Copy this file to /etc/systemd/system/vncserver@:1.service | |
| # 2. Edit User= | |
| # e.g "User=paul" | |
| # 3. Edit the vncserver parameters appropriately in the ExecStart= line! | |
| # e.g. the -localhost option only allows connections from localhost (or via ssh tunnels) |

This is a gist with a set of helpful performance tricks and best practices that I've found on the internet.
To remove a submodule you need to:
| version: '2' | |
| services: | |
| db-bootstrap: | |
| image: dayreiner/centos7-mariadb-10.1-galera:latest | |
| container_name: db1 | |
| restart: never | |
| expose: | |
| - "3306" | |
| - "4567" | |
| - "4568" |
| - What do Etcd, Consul, and Zookeeper do? | |
| - Service Registration: | |
| - Host, port number, and sometimes authentication credentials, protocols, versions | |
| numbers, and/or environment details. | |
| - Service Discovery: | |
| - Ability for client application to query the central registry to learn of service location. | |
| - Consistent and durable general-purpose K/V store across distributed system. | |
| - Some solutions support this better than others. | |
| - Based on Paxos or some derivative (i.e. Raft) algorithm to quickly converge to a consistent state. | |
| - Centralized locking can be based on this K/V store. |
