Hello,
2 suggestions are recommended below:
(1) Using latest android BSP( android7.1.1), please!
In android4.4, MJPG encoding is done by software, which can make speed of taking picture slow, Android5.0 BSP and later, MJPG is encoded by VPU(hardware), so it's speed should be improved more.
(2) Using MJPG USB camera
You can try using USB carmera with MJPG video stream, when taking a picture, MJPG encoding doesn't need to be done, so speed may also be improved.
Have a great day,
TIC weidong
