Error when QMediaPlayer setMedia QTemporaryFile

[Charlez Kwan]

Hi everyone, I'm trying to play write a wav file in QTemporaryFile and want to play it via QMediaPlayer. But i get the following error:

DirectShowPlayerService::doRender: Unknown error 0x80040266.

Does someone know what could be the problem?

So does it work with a normal QFile?

I found out the problem, QTemporaryFile cannot set flag for append, it makes the audio file corrupted.
