Recently, I encountered a problem that videoview failed to load. The video pressed by my colleagues could not be played on the 5.1.1 system, and an error (1, – 2147483648) was reported. Looking up the error code, I found that it was because the format supported by each version was different. My colleagues pressed a MP4 format which was not supported by 5.1.1, and later changed to h264avc format MP4, which could be loaded and played
