Why the vpu output a color changed video?

Question asked by Lv Smalight on Jun 4, 2013

Hello, Experts and friends!

Now, I want to transform a yuv video to mp4.

I run the mxc_vpu_test.out in the i.MX53 platform.

(mxc_vpu_test.out is a example program int the i.MX53 development board)

the command line as follow:

./mxc_vpu_test.out  -E  "-i test.yuv -o testvpu.mp4 -w 720 -h 576 -f 2 -g 25"

 

the format of the input file "test.yuv" as follow:

Sampling Format: yuv422 planar progressive

Componet Order:  Y,U,V

Progressive,Planar

PAL 720*576

 

 

After encording finished, I got the video file "testvpu.mp4".

I play it int microsoft media player in my PC. But I find the picture's color of testvpu.mp4

is more yellow than test.yuv. It's so obvious that I don't satisfied the result.

there are the two files in attachments. you can play them and view the effect.

 

if ther are some parameter is error or the "mxc_vpu_test.out" need some other parameters?

How can I get a more clearly video? Thanks for any help.
