I'm using FFMPEG to produce a video consisting of a single monchrome JPG image:
ffmpeg -y -loop 1 -framerate 30 -t 5 -i SplashBW.jpg Splash.mp4
There are two issues with the resulting video:
When viewed with Irfan View it looks fine. I don't know whether the issue is with the original JPG, the FFMPEG command, or the viewers. Naturally, I want it to render properly on all outputs.
The first two links below look fine in my browser (Chrome) when I open them. The third link is a screen recording of what I see when I try to play the video with the Film and TVapp.

Your input image has only one component channel - luminance. Most players deal with H.264 streams containing three component channels - luminance or 'brightness' (Y) and two for chroma or 'color' (U & V). When the H.264 encoder encodes a luma-only stream, it stores it using a syntax which many players don't handle well. So, we tell ffmpeg to add chroma components which will have neutral values (since there's no color valence in the source) before sending it to the encoder. We'll add the most common form of YUV encoding - yuv420p.
So,
