My environment is the latest Qt5.5 + Win8.1 64 pro, made of Qt players cannot play mp4 video format, can play WMV format video, but there is no Qt environment program a package on others on the computer even WMV format video may not be able to play, and play a video program crash, look online to say is the problem of video decoding, on my computer Windows Media Player can play in mp4 and WMV format video, do you have encountered such a situation

CodePudding user response:

QMediaPlayer itself cannot to video decoding, he is by calling the bottom of the decoder to decode video, upper users feel can use on all platforms, other people's computer may not be suitable for QMediaPlayer decoder so I can't play video
