I obtained this video from directly reading the memory of a hardware encoder. The encoder supposedly produces a HEVC (H.265) or H.264 video stream, but I can't accurately play or convert the file with ffplay or ffmpeg.
Given the information below, is this something I might be able to play correctly? Is it incomplete data, and something more may be needed to reconstruct the video?
Link to the file I'm trying to play.
This is what ffmplay is producing when trying to play the file. It's possible to view the outlines of the actual recorded objects. Seems like information about the pixels that change? That would be something to be expected from a H264 or H265 stream...
ffplay -f rawvideo -video_size 1920x1088 -framerate 5 -pixel_format yuv420p stream.bin
And this is a sample of the actual recorded footage, for comparison purposes:
When I try to play it using ffplay, no arguments:

EDIT
There's another dump I'd like you to take a look at: link to file.
ffplay -f rawvideo -video_size 1920x1088 -framerate 5 -pixel_format yuyv422 -vf scale=320:-1 0x239F.bin
And the correct image, for reference:
