MediaSourceAudioInputNode.Position property doesn't work properly

Question

I'm using MediaSourceAudioInputNode.Position for Audio Graph to get the position of the playback. It always gives 0 value.

For comparison, using Media Playback class such as MediaPlaybackSession.Position Property works fine. It gives me the position of the playback.

Answer 1

Hello,

Welcome to Microsoft Q&A!

It always gives 0 value. Is there a way to get the position/time of the playback for live content?

@vansa I've gotten the response from the team and we could confirm this behavior is by design. Live streams don't have an end, so its file duration is set to -1. This value is generally used to calculate the current position in conjunction with a calculation based on the sampling rate of the audio format. The result of this calculation is always going to be 0 because of the duration value.

Currently, there is no workaround when the live stream doesn't have a specified end time or duration.

Thank you.
