576i video getting squeezed

 Not sure is that correct terminology.

Hi,

Looking at your ffmpeg I see:

The video start-time is 4,905,841ms
The audio start-time is 4,904,952ms
=> Offset is 889ms

This is often an indication of poorly authored files!

The resolution is 720x576 which is a 4:3 anamorphic aspect ratio.
However, the media is incorrectly marked as having an aspect ratio of 16:9

That would explain the funky condensed view you see.
You'll want to replace the media or try to fix the media
You could try using ffmpeg with a command like:
 

ffmpeg -i input.ts -c copy -bsf:v h264_metadata=aspect_ratio_idc=1 output.ts

-i input.ts: Specifies your input file.
-c copy: Copies the video and audio streams without re-encoding.
-bsf:v h264_metadata=aspect_ratio_idc=1: Sets the aspect ratio metadata to 4:3.
output.ts: Specifies your output file.

This command changes the aspect ratio metadata to 4:3 without re-encoding the video.

Thank you for detailed explanation. It’s live tv SD channels that this happens to and this happens in Roku as well.
