Doesn't always work for .MOV files on Mac about downsize

[kcjl519]

Actually an extended problem with not playing on finder, is that it won't work on mobile safari / chrome, and desktop safari.

I have tried with manually adding -pix_fmt yuv420p and it resolves the problem

Also the filename may not always be .mov.
I have videos shot on iphone that is saved as .mov and works without pix_fmt and I also have videos shot with DJI Mimo that's saved as .mp4 but doesn't work without pix_fmt..

Hi @galactictech. First of all apologies for the very slow reply. Thank you for raising this and for providing a fix. I can reproduce the issue locally as well.

@kcjl519 based on your comment we might need more than a check on the .mov extension. I will investigate this as a priority. Do you have any suggestion? I wonder if it's safe to add -pix_fmt yuv420p systematically.
