I finally found a video that won't play correctly

After more than three years of daily heavy usage.
It shows heavy artifacts on the lower half of the screen.
Video plays correctly if I disable “Accelerate MPEG4” In System/Player/Videos.
It’s possibly a bad encode and I don’t mind disabling HW Acceleration/re-encoding it, just thought you would know.

Mediainfo for it:

The file is H263 which is interesting.

Can we get a sample of the file?

Thanks

Sam

Here’s a sample, cut with ffmpeg: WeTransfer - Send Large Files & Share Photos Online - Up to 2GB Free

Vero can’t decode h263 in hardware. Other h263 clips I have are played in software (ffmpeg) automatically. Your video is Mpeg4 Part 2 which is h263 compatible (says Wikipedia) but Kodi is trying to play it in hardware. A fix would be to get it recognised and send it to ffmpeg.

E’ un video codificato alla cazzo di cane.

Sorry for the italian, other forum users. It’s an inside joke about the file.

We just need to detect hints properly and return false in AMCodec.
Should be simple enough.

I’ll give you an update when this is done.
