===Exsiting bugs===
====Bug description====
*Can not encode to H.264 stream at full framerate
Using the gstreamer instructions used in the previous section to encode the video, the full frame cannot be reached. It can only reach about 17 frames. Limiting all CPU speeds to 600MHz which gives a stable 25FPS in PAL mode.
*Memory leak
Using rkisp as a gstreamer plug-in, there will be serious memory leaks.
====Bug Analysis====
Although rockchip's rk3399 supports camera module of YUV format, there are serious bugs in the gstreamer plug-in they provide.
