[FFmpeg-devel] pixel format convertion yuv422p->yuv420p->yuv411p->yuv422p degrade picture

[Maksym Veremeyenko]

Dear Developers!

I was testing pixel format changing and found that convertions like:
yuv422p->yuv420p->yuv411p->yuv422p
degrade picture - it become greener.

To prove this i did a shell script, see attached. On 50th iteration 
picture is almost compleately green.

Is it normal behaviour for pixel format converting or it is a bug?
