Directsound Slaving info problem
I am developing an analog capture filter driver. There was an AV sync issue
after the long time live source playback (2 hr). The audio pin always queue few buffers after long time playback. I have checked the video and audio PTS with each media transfer sample, they look like no problem. I have a question with Default Directsound Device filter. There is information in Default Directsound Device Properties-Advanced-Slaving Info-Rate. The “Rate” should be 48KHz with my device, but it will be changed with the “High Err” and “Low Err” parameters. Could I set any parameter to change the “High Err” or “Low Err” values in audio pin of analog capture filter? |
