# FFmpeg OpenBSD
FFmpeg scripts for screen recording YouTube videos and YouTube live streaming on OpenBSD.
# Stream Key
If you intend to do live streaming, make sure to place your Stream Key under the `~/Document/.streamkey` file.
# Enable microphone
The microphone is disabled by default on OpenBSD.
Temporary enable:
```bash
$ doas sysctl kern.audio.record=1
```
Permanently:
```bash
# echo kern.audio.record=1 >> /etc/sysctl.conf
```
# Audio playback
The scripts are capable of recording/streaming audio playback as well. It is done by
utilzing `mon0.` in sndio. You need to enable that or modify the scripts.
Enabling `mon`:
```bash
$ doas rcctl set sndiod flags -v 80 -s default -m play,mon -s mon && doas rcctl restart sndiod
```
You can specify the volume of playback with `-v` flag.
# Microphone volume control
It is impossible to control microphone volume using FFmpeg. You need to set it with `sndio` or `cmixer`. I recommend the latter.
Install cmixer:
```bash
$ doas pkg_add cmixer
```
If you open the program, it defaults to `snd/0`, your internal sound card.
To switch the sound card, you must export the `AUDIODEVICE` variable and then open the mixer.
Example,
```bash
$ export AUDIODEVICE=snd/1 # pointing to the first external sound card
$ cmixer
$ unset AUDIODEVICE
```
Putting it all together, you can create an alias,
```bash
$ alias cmixer-microphone='export AUDIODEVICE=snd/1;cmixer;unset AUDIODEVICE'
```
