QT Media Error: DirectShowPlayerService::doRender: Unresolved error code 0x80040266

problem¶

First of all, for this problem, the compilation can also pass, but the operation will cause an error:

DirectShowPlayerService::doRender: Unresolved error code 0x80040266

reason¶

The bottom layer of multimedia playback in Qt uses DirectShowPlayerService, so installing a DirectShow decoder, such as LAV Filters, can solve the problem of running errors.

Download and install LAVFilters:
