The timestamps of captured frames are provided directly by MediaCodec with the encoded packet:

scrcpy/server/src/main/java/com/genymobile/scrcpy/SurfaceEncoder.java

Line 175 in 206809a

streamer.writePacket(codecBuffer, bufferInfo);

scrcpy/server/src/main/java/com/genymobile/scrcpy/Streamer.java

Line 82 in 206809a

long pts = bufferInfo.presentationTimeUs;

This is (or should be) the capture time, not the time where you retrieve the encoded frame, so if you check the current time when MediaCodec provides a frame, it's a bit later, depending on your device/encoder, so it's expected that a trace would be "delayed" compared to the capture time. Maybe you should subtract the duration between the capture time and the current time immediately after the MediaCodec call returns if you want to compare with your own timestamped traces.
