</table><br></div><div>It seems the vaapijpegdec is able to perform the decode in 3.16ms vs almost 17ms for the software decoder (jpegdec) yet the framerate is 12.14 FPS so almost double with the software decoder. Do you know why this could be?</div>

Could you try to increase jpegparse between depay and vaapijpegdecode?<br>
