Quicktime not playing a h264 aac encoded file - why?

Quicktime says "This file isn't compatible with quicktime player" when I try to play an mp4 file.

The info shows the encoding as : H.264, AAC, QuickTime Text

The file plays fine with VLC. I need this file in my iTunes library so that I can stream it, hence the importance of this question.

Strange thing is I have other files with similar codes that QT can play fine. How can I check why this file is incompatible?

Here is the log from ffprobe:

Please try to add "-vf format=yuv420p".

I have the same issue, I have a video of

Stream #0:0(und): Video: hevc (Main) (hvc1 / 0x31637668), yuv420p10le(tv, bt709/unknown/unknown), 1170x2532, 2534 kb/s, 42.16 fps, 600 tbr, 600 tbn, 600 tbc (default)

And then I do:

ffmpeg -i in.mp4 -r 25 -vf scale=300x500 o.mp4

I got the o.mp4 as

Stream #0:0(und): Video: h264 (High 10) (avc1 / 0x31637661), yuv420p10le(tv, bt709/unknown/unknown), 300x500, 53 kb/s, 25 fps, 25 tbr, 12800 tbn, 50 tbc (default)

I can't play it with QT. Then I changed to

ffmpeg -i in.mp4 -c:v libx264 -profile:v high10 -level:v 4.0 -vf scale=300:-1 -vf format=yuv420p  o.mp4

The video is good now. I supposed "-vf format=yuv420p" is the crucial, and szatmary might be right, "QT can't play 10bits with High 10".

The final video is

Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, bt709/unknown/unknown), 1170x2532, 415 kb/s, 42.16 fps, 42.16 tbr, 2380950.00 tbn, 84.32 tbc (default)

Quicktime can not play 10 bit h.264, hence:

This file isn't compatible with quicktime player
