Audio out of sync in DirectShow app on Win7 (HVR1250)
W have developed a win7 app that - among other things - plays analog TV. We have been testing the app with Hauppauge HVR-1250 and the most recent drivers on Win7 64-bit. The usage of the tv tuner is as simple as it could be: issue a play at startup and stop when the app terminates.
The problem is that after a few hours the audio is not in sync with video.
We use a default DirectShow clock which is the audio renderer.
Could someone please let us know if support for DirectShow in Win7 environment is reliable?
