Local video won't play - unsupported format

mike

Hello,
I'm having an issue with some local videos on my Android phone - they just won't play while others are playing with no issue.
Some of the videos I have even appear to be of the same parameters like resolution, codec type and frame rate. And still one file is played flawlessly and the other one ends up with the error.
What could be the reason?

Here's some details for one of the video files that won't play (taken from VLC) and I have another one with the same details and it plays with no issue:

Stream 0
Codec: H264 - MPEG-4 AVC (part 10) (avc1)
Type: Video
Video resolution: 1920x960
Buffer dimensions: 1920x960
Frame rate: 30
Decoded format:
Orientation: Top left
Chroma location: Left

Stream 1
Codec: MPEG AAC Audio (mp4a)
Type: Audio
Channels: Stereo
Sample rate: 44100 Hz
Bits per sample: 32

I tried the following:
- Scale resolution down to 720p
- Remove audio stream
- Convert to MJPEG

The issue's still there.

Ok I seem to have found the fix. Probably there is a more optimal way but at least it worked for me.
I just took ffmpeg and converted the original file into mjpeg without any other changes and then took the output and converted it back to x264 using command like

-i 1.mp4 -q:v 0 -c:v libx264 2.mp4

here's the ffprobe output for original file that won't play:

And here's one for the final one that plays nicely:
