I have a Samsung Galaxy S21.
By default, it saves video in one of the two codecs ; H264 and HEVC.
Is it possible to implement VVenC pipeline so that they are directly saved as VVC?

Hi @Razor54672, thank you for asking me your question.

For default of h264/x264 and HEVC, that answer is yes for saving/encoding video in Termux.
For VVenc using your Android device does not work in Termux, because the errors and warnings, however only vvdec in Android can work.

I tried build vvenc of Android build on my Ubuntu 22.04 LTS, it did not work, you can create issue on fraunhoferhhi/vvenc:

Used command: make release.

Let me know and I can help you with your question.

Hello, @Razor54672! As you know... the Android vvenc binaries are available.

You can download Android VVC binaries (AndroidVVC.7z) and run on Termux.
