IMX 50 MOV Issue

Post by vijm1972 » Tue Jul 19, 2016 1:26 pm

Hi Steipal,

I am trying to transcode IMX 50 MOV using encoder IMX D-10 or custom FFmpeg, after conversion Display Aspect Ratio is showing 1.408 instead of 4:3. I have tried with custom FFmpeg and command prompt option, but it's still showing same ratio. I have tried below command.

-vcodec mpeg2video -r 25 -s 720x608 -aspect 4:3 -pix_fmt yuv422p -minrate 50000k -maxrate 50000k -b:v 50000k -bufsize 2000000 -rc_init_occupancy
2000000 -rc_buf_aggressivity 0.25 -intra -dc 10 -ps 1 -qmin 1 -qmax 3 -top 1 -flags +ildct+low_delay -vtag mx5p -vbsf imxdump -acodec copy

Please find below screen shot for your reference.

I had also tried with codec copy option but it's still showing same issue. I haven't found option to keep the ratio 4:3.
Please suggest.

Thanks,
Vijay
