无法正常间隔1分钟生成一个mp4视频

It's possible that key frames have not been received. Has the other party suddenly changed the encoding format?

无法正常间隔1分钟生成一个mp4视频

有可能一直没收到关键帧。是不是对方突然变更了编码格式？

It shouldn't be, I've tried for several days, every time it runs for a few hours and then does this, click stop playing and then continue playing, zlm resumes with an interval of one video per minute, and I couldn't find any problem by looking at the log

应该不是，试了好几天，每次都运行几个小时后就这样，点击停止播放然后再继续播放，zlm又恢复间隔一分钟一个视频，看log也没看出啥问题来
