Problem playing USB file on TV

[akkers]

I have a 1hr MP4 file which plays ok on my PC. I copied it to a USB stick and tried playing it on my TV. It plays for a while and then picture freezes.
I thought it might be the filesize (3Gb) or bit rate but these look reasonable. Are there any tools that can run the file and tell whats wrong?

That's a pretty hefty bitrate for 720x576. Might be choking on that? Also, 50fps.

I wonder if the "odd" display aspect ratio might be messing with the TV upscaler? 720x576 is normally 4:3 DAR.

Use clever FFmpeg-GUI.
Load your mp4, click main page, click multiplex, set all like in the picture below and click multiplex. Done.

Try the new created mp4 on your TV.
If the display aspect is wrong, repeat the operation with 1.78 instead 1.33

So if the aspect ratio is not one of the popular ones (16:9/4:3) does the TV try to upscale/downscale? Extra work?

You can change the display aspect ratio at any time without recoding

Seems your clip was mis-coded. Assuming taken from a DVD, it should have been either 16:9 or 4:3 DAR.
(720x576 is only 5:4 DAR when using square pixels, which is NEVER when on a DVD)

There are tools here to permanently fix things like that (not necessarily requiring a reencode), but as mentioned, you should be able to set that at runtime on the tv.

On a side note, if I have footage that is 4:3, can I reset the DAR flag to 16:9 so that always plays full screen on wide-screen TVs? Yes it will get stretched a bit but sometimes you can live with that.
Will that cause any problems playing that footage on TV>

You can do this, but it is absolutely not recommended, as the 4:3 content should also be played as 4:3.
Examples are broadcast contents from the times before widescreen TVs.

I say this because I had another SD video 4:3 which I played on my Sony TV and it was automatically stretched to 16:9. Even though there was small sign of stretching the pic looked acceptable. I played the same clip on a Samsung TV which just played in 4:3; the pic looked ok but it was too small. A tiny pic occupying about 60% of a 65'' screen.
