abstract void |
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. |
