    This works on Windows, so I think the format is fine.

      No, it's not. Read the error you posted here:
      data:image/jpg;base64,: Unsupported image format

        @mikeeeeee
        might actually be an endian error, where do you get your Bytearray from?

              Do you get this on Android?
              For which platform were these libraries build?

                      @mikeeeeee I do this on my Android application, and it works fine (Android 7.1/7.0 and Qt 5.7). Do you have enabled multimedia support in you PRO file with QT += multimedia ?

                          @mikeeeeee So your real problem is not showing PNG but taking a screenshot? right?
