onFrameRendered(MediaCodec codec, long presentationTimeUs, long nanoTime)
Called when an output frame has rendered on the output surface. |
void onFrameRendered (MediaCodec codec, long presentationTimeUs, long nanoTime)
Called when an output frame has rendered on the output surface.
Note: This callback is for informational purposes only: to get precise render timing samples, and can be significantly delayed and batched. Some frames may have been rendered even if there was no callback generated.
| Parameters | |
|---|---|
codec |
MediaCodec:
the MediaCodec instance |
presentationTimeUs |
long:
the presentation time (media time) of the frame rendered.
This is usually the same as specified in queueInputBuffer(int, int, int, long, int); however,
some codecs may alter the media time by applying some time-based transformation,
such as frame rate conversion. In that case, presentation time corresponds
to the actual output frame rendered. |
nanoTime |
long:
The system time when the frame was rendered. |
