Comment (by Kdmeizk):

 Replying to [comment:1 Cigaes]:
 > ffmpeg and ffprobe will not lie to you. They tell you what they are
 doing. You are misunderstanding the whole concept of pixel formats. Please
 stop opening issues until you understand it better.
 I can try to better explain what you misunderstood, because I did not
 write explicitly or implicitly something like “ffmpeg and ffprobe lie”.
 For the pixel formats, ffmpeg’s output section displays the value set to
 “-pix_fmt” which is the pixel format “nv12”. In ffprobe, I believe the
 function
 “[https://git.videolan.org/?p=ffmpeg.git;a=blob;f=libavcodec/utils.c;hb=HEAD
 avcodec_string]” is called and contains:
 {{{
             snprintf(buf + strlen(buf), buf_size - strlen(buf),
                  "%s", enc->pix_fmt == AV_PIX_FMT_NONE ? "none" :
                      av_get_pix_fmt_name(enc->pix_fmt));
 }}}
 So the pixel format “yuv420p” is displayed.
