## Advanced settings
|
||
|
|
|
||
|
|
Within **/etc/ffplayout/advanced.yml** you can control all ffmpeg inputs/decoder output and filters.
|
||
|
|
|
||
|
|
> **_Note:_** Changing these settings is for advanced users only! There will be no support or guarantee that it will work and be stable after changing them!
|
||
|
|
|
||
|
|
For changing this settings you need to have knowledge about hardware encoding with ffmpeg. Good starting points are:
|
||
|
|
|
||
|
|
- [HWAccelIntro](https://trac.ffmpeg.org/wiki/HWAccelIntro)
|
||
|
|
- [VAAPI](https://trac.ffmpeg.org/wiki/Hardware/VAAPI)
|
||
|
|
- [QuickSync](https://trac.ffmpeg.org/wiki/Hardware/QuickSync)
|
||
|
|
|
||
|
|
### Example config
|
||
|
|
|
||
|
|
Here an example with Intel QuickSync:

**At the moment this function is _experimental_, if you think you found a bug: check full decoder/encoder/ingest command with ffmpeg in terminal. When there the command works you can open a bug report issue.**

Please don't open issues for general command line helps!
