I have a sample.mp4 which is currently not playable on VLC or media player and I've checked the FFmpeg values and get the below result? Any help would be greatly appreciated.
It is all about the proprietary codec, i.e. IMM5. The VLC and FFMPEG can't deal with it except patching the avcodec manually using https://firstname.lastname@example.org/. Of course, you need to re-compile the ffmpeg using the IMM5 supported avcodec lib.
