1. Looks like libfdk-aac is NOT free. So, I disabled it...
```console
error: Output ID 'ffmpeg_muxer' not found
error: Failed to create output 'adv_file_output'!
error: Encoder ID 'ffmpeg_nvenc' not found
error: Failed to get properties for encoder '' (ffmpeg_aac)
error: Could not enumerate any AAC encoder bitrates
error: Failed to create audio encoder (advanced output)
```
2. ffmpeg was built from source and installed. But, there is NO such tools `ffmpeg_muxer` or `ffmpeg_nvenc` generated...
It looks I've got to enable --enable-libfdk-aac to build ffmpeg, which further supports OBS. However, libfdk-aac is NOT a free open source . Does that mean: OBS cannot work without relying on some non-free software?
Cheers
