### Update 21th May 2022 of FFmpeg vvdec support
Good news, you can play .mp4 file after .h266 and audio format were merged into mp4 playable of VVC.
About [xHE-AAC](https://www.iis.fraunhofer.de/en/ff/amm/broadcast-streaming/xheaac.html), there is no decode support of FFmpeg, the reason is a license fee, but except [Exhale](https://gitlab.com/ecodis/exhale) (encoder) is free to use and open source. However, you can also merge encoded xHE-AAC audio into mp4 too.
To make playable VVC with audio, you need VVC video encoded, audio file and [GPAC Nightly build](https://gpac.wp.imt.fr/downloads/gpac-nightly-builds/). Code for mp4box/gpac:
```
mp4box -no-probe -add video.266 -add audio.opus -new convertedvvc.mp4
```
For Linux and Mac OS users: Replace **mp4box** by **gpac**
