The follow are three images respectively getting from raw yuv、jpeg encoder、mpeg4 encoder. The jpeg encoder was set to the highest quality 97. It is clear that the jpeg is the lowest quality.
How to improve it ?
Is the problem only related to contast ? Jpeg as such does not have any other quality knob apart from QF. Can you please send the original YUV as attachment to us, we will try reproducing the issue here.
