Actual Time Of "nativegettimestamp" In "surfacetexture"

I'm writing a video processing app and need to know the actual time of each frame. The app works fine at first when I used elapsedRealtime To compute the time offset: long timeOffs

Solution 1:

MediaCodec doesn't invent the timestamps. The buffers that MediaCodec return only contain the same values for presentationTimeUs as you pass in the presentationTimeUs parameter to queueInputBuffer, or when using Surface input, is set on the input surface using eglPresentationTimeANDROID.

So you need to check with whichever piece of code that actually produces the timestamps to know what time reference they use.
