Freeing memory in Example1

[goodintention]

Thank you for providing this wonderful package,
On Example1, when I choose MP4 output format, the app’s memory usage increases by +59 MB every time I click the ‘Execute’ button,
How can I free the memory after encoding?
I’m using the 32-bit Delphi 10.1 Berlin compiler.
Thanks.

Hi,

I made some changes in the sample.

The main issue was that FSampleSinkWriter was not correctly freed from memory.
The others are creating and freeing the sinkwriter in combination with repeatetly calling MFStartup increases memory consumption while running a lot. This will not affects memory when closing the app, but should not happen.

The changes in the sample are uploaded to GitHub.

Thank you for reporting this issue.

Thank you for the changes,
now there’s no memory issue, but the example sometimes freezes.

Hi,
On what codeline does the app freeze exactly?

[goodintention]

Hi,
when I comment out this line:
//hr := pRintWriter.Flush(stream);
the app stops freezing.

I remember there are some issues using the Flush method.

Thank you and regards, Tony.
