Research direction

Start by reproducing the issue on a Raspberry Pi 4 using the attached vert.zip sample and the reported command, omxplayer vert.mp4, with the listed firmware and kernel versions. Compare playback with the Raspberry Pi 3B+ and the older Raspbian release; done means the 1080x1920 H.264 video displays without corruption on the Pi 4.

Description

Describe the bug
When playing a vertical video (h264, 1080x1920) using mmal decoder,
video display is corrupted.: only the left part of the frame is correct and the other part is full of noise/random colors.

To reproduce

  • prepare a microsd with Raspbian buster with desktop 2020-02-05;
  • boot the Rpi4
  • copy the attached vidio to the Rpi
  • play the video with: omxplayer vert.mp4
  • the video display is corrupted

Expected behaviour
Video should play without corruption.

Actual behaviour
When playing a vertical video (h264, 1080x1920) using mmal decoder,
video display is corrupted: only the left part of the frame is correct and the other part is full of noise/random colors I attached a picture of the video corruption.

After upgrading the firmware, the problem still exists.

Additional info
If I put the same microsd on a rpi3B+, the video plays correctly and the bug wasn't present in previous raspbian version (2019-09-26).
