I used the cordova-plugin-file-opener2 plugin to open the MP4 video, only the file name and file type displayed。But the general MP4 video can be played directly。
So, I switched to cordova-plugin-streaming-media to play this video with only sound but no picture。

The AVC Level and bitrate both higher than the first video, but it plays normally。
Apple doesn’t have specific specs, but says it supports MP4 and H.264.
Does anyone know the more detailed H.264 restrictions on iPhone？
