video not playing on Android (chrome) and iOS (safari)

Hi I have a few video that DOES NOT play in Android (directly on Chrome) and on iOS (directly on Safari) but plays on Windows, Mac and Linux on any browser.

Here is the ffprobe output

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'intro_sequence_01.mp4':
  Metadata:

    Metadata:

and here is the ffprobe output of another video that DOES play on Android and Chrome:

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'Torcia_960x540.mp4':
  Metadata:
    major_brand     : mp42

    Stream #0:0(eng): Video: h264 (Main) (avc1 / 0x31637661), yuv420p(tv), 960x540 [SAR 1:1 DAR 16:9], 10576 kb/s, 25 fps, 25 tbr, 25k tbn, 50 tbc (default)
    Metadata:

      handler_name    : Mainconcept MP4 Video Media Handler
      encoder         : AVC Coding

Both are .mp4 format and are using h264 codec. As far as I can see, I notice a difference in codec profile h264 (High 4:4:4 Predictive) vs Video: h264 (Main) and yuv444p vs yuv420p(tv) and on metadata section.

I tried re-encoding the first video with ffmpeg but without success. Does anyone know why video1 is not compatible with Android and iOS and how to re-ffmpeg it to make it play? Thanks!

    • @aergistal: Thanks! I have reencoded like that ffmpeg -i original.mp4 -vcodec libx264 -acodec copy -vprofile main -pix_fmt yuv420p reencoded.mp4 and now it plays! Thanks again! If you turn your comment into an answer I'll vote and accept it.

According to aeristal comment on my question above, I have re-encoded my video like this:

ffmpeg -i original.mp4 -vcodec libx264 -acodec copy -vprofile main -pix_fmt yuv420p reencoded.mp4

and now it plays back on Android and iOS too.

The key switches are -vprofile main and most important -pix_fmt yuv420p as Android / iOS does not support Hi444PP profile as stated by aergistal
