DM365 H.264 Encoder YUV test files

Fikret Alim

Hi,

I am trying to encode YUV test files by using digital video test bench on DM365 processor. For this purpose, I have downloaded some YUV test sequences and convert as defined in the dvtb_user_guide.pdf. But, the encoded files have some problems; the color is different from the original clip, there are some shadows passing. I think this is related to the YUV format. 

My question is; do I need to use only 4:2:0 semi planar YUV test files? Is it possible for me to use the downloaded test files with some kind of conversion with an external software or by using DM365? If I can only use 4:2:0 format, then can you please tell me where can I find those clips? Most of the clips I have downloaded are not in this format.

Thanks&Best Regards,

Fikret

    Hi,

    You need ti use only YUV420 semi planer YUV files for DM365 H.264 codecs. You can convert file from one YUV format to other through ffmpeg.

    Dear Yashwant,

    Thank you for your prompt response. I have already tried to convert the file with ffmpeg with the following command. 

    avconv -s 720x480 -pix_fmt yuv420p -i CITY_704x576_30_orig_01_yuv/ -pix_fmt nv12 city_nv12.yuv
    avconv version 0.8.3-4:0.8.3-0ubuntu0.12.04.1, Copyright (c) 2000-2012 the Libav developers
    built on Jun 12 2012 16:52:09 with gcc 4.6.3
    CITY_704x576_30_orig_01_yuv/: Operation not permitted

    I have also tried ffmpeg command instead of avconv, but the result is same. Do you have an idea about that?

    BR,

    Ok, no problem that's my fault. I haven't entered the source file correctly. So it is OK. Thanks again.
