avcodec_find_best_pix_fmt_of_list gives wrong format

[str]

Summary of the bug:
avcodec_find_best_pix_fmt_of_list gives me AV_PIX_FMT_PAL8 instead of AV_PIX_FMT_GRAY8, although src is AV_PIX_FMT_GRAY8 and it is contained in the list.
How to reproduce:
Use the ffmpeg API and try to call avcodec_find_best_pix_fmt_of_list with src = GRAY8. As destination list I used the list of png encoder, which contains GRAY8 as well as PAL8.

Is this also reproducible with current git head?
How can I reproduce this problem?

Replying to cehoyos:

How can I reproduce this problem?

Yes. This problem also occurs in git head.
I already explained how to reproduce:
Simply call
avcodec_find_best_pix_fmt_of_list(pix_fmt_list, AV_PIX_FMT_GRAY8, 0, 0)

with the pix_fmt_list taken from png encoder for example.

What I meant was:
Assuming this is not reproducible with ffmpeg (or is it?), could you provide source code that allows to reproduce the problem?

[str]

  AVPixelFormat list[] = {PIX_FMT_PAL8, PIX_FMT_GRAY8};
  AVPixelFormat src = PIX_FMT_GRAY8;

  AVPixelFormat res = avcodec_find_best_pix_fmt_of_list(list, src, 0, 0);
//res is PIX_FMT_PAL8 instead of PIX_FMT_GRAY8
