probably YUV420P vs YUV422P
Some players only supports YUV420P.

Re: [FFmpeg-user] Problem with videos not playing in mobile browser
Hello,
Could you share a URI for one of these videos?
Also, do they play on mobile before you add the text filter?
Cheers,

May the source be with you,

Dear all
I am new to this forum.
I have noticed that some of my videos, encoded with ffmpeg and uploaded
to my websites, do not play on mobile web browsers, but they work
perfectly well on desktop browsers on my Linux machine. I get either a
message saying 'file is corrupted' or no message at all (just a blank
video) depending on the browser. I've tried Brave, Firefox and Chrome,
on an iPhone, a Samsung tablet and a Samsung Galaxy s10 plus. The 'bad'
videos consistently fail to play on mobile devices.
I've run an ffprobe on two .mp4 files: one which works on a mobile and
desktop browser (good.mp4) and one which will only play on a desktop
browser (bad.mp4. These are partial outputs (the rest of the output for
the two files seems identical):

[FFmpeg-user] Problem with videos not playing in mobile browser
Dear all
I am new to this forum.
I have noticed that some of my videos, encoded with ffmpeg and uploaded
to my websites, do not play on mobile web browsers, but they work
perfectly well on desktop browsers on my Linux machine. I get either a
message saying 'file is corrupted' or no message at all (just a blank
video) depending on the browser. I've tried Brave, Firefox and Chrome,
on an iPhone, a Samsung tablet and a Samsung Galaxy s10 plus. The 'bad'
videos consistently fail to play on mobile devices.
I've run an ffprobe on two .mp4 files: one which works on a mobile and
desktop browser (good.mp4) and one which will only play on a desktop
browser (bad.mp4. These are partial outputs (the rest of the output for
the two files seems identical):
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'bad.mp4':

-write_tmcd false -s 1280x720 -preset medium -crf 24 "full/${f%.*}.mp4"
done
Can anybody offer any insight?
My thanks.
