ffmpeg output doesn't play on multiple devices
22 janvier 2019, par jchaykowI have read the other stackoverflow posts regarding this topic so I am fairly certain this is not exact duplicate.
ffmpeg exports a video that seems to only play on select players. I want to export a video that plays on iphone/mac/general players. I have seen the suggestions for the
-pix_fmt yuv420p
tag but this does not seem to work anymore - I read that Mac has since changed their systems that makes it not compatible anymore.I am running :
ffmpeg -start_number 1 -framerate 4 -pix_fmt yuv420p -i screen%01d.png output.mp4
This all works fine and I can see the video by doing :
ffplay output.mp4
But I would like to be able to transfer this to mobile or general playback, any way to do this, ideally using ffmpeg ? I’d rather not use two tools to do 1 job.
