Reminder: iPhone wants H.264 encoded videos
I came over a bug where the video wouldn’t play on iPhone, but worked on a Mac.
<video> <source src="flower.mp4" type="video/mp4" /> </video>
The HTML tag was valid, the video HTTP response wasn’t an issue. Instead it was unsupported video encoding (which took me hours to figure out).
And here’s how I made the video compatible with iPhones, using ffmpeg:
# Replace "input.mp4" ffmpeg \ -i input.mp4 \ -vcodec libx264 \ -acodec aac output.mp4
I also realized getting stuck on this problem 5 years ago 😩
