WriteConfigurationToPreferences() doesn't save

Hi,

I tried to write a program that prints the current bmdDeckLinkConfigVideoInputConversionMode and change it and then exit directly.

Code: Select all

result = deckLinkConfiguration->SetInt(bmdDeckLinkConfigVideoInputConversionMode, videoInputConversion);

after it returns S_OK, I tried to call

Code: Select all

result = deckLinkConfiguration->WriteConfigurationToPreferences();

followed directly by

Code: Select all

deckLinkConfiguration->Release();

however around once every two times the program is run, it doesn't actually change the preferences even though SetInt() and WriteConfigurationToPreferences() returns S_OK..

Is there any special handling that needs to be done?

The code is available at https://github.com/afriza/decklink-adapter

Hi Afriza,

Thanks for providing your code sample, we will resolve issue in a future release. As an interim workaround, you could add delay between IDeckLinkConfiguration::WriteConfigurationToPreferences() and IDeckLinkConfiguration::Release(). I added call to std::this_thread::sleep_for() with success.
